Week 8 Shift 2

The new crop of ICU nurses is coming on this month. We’ve recruited our usual blend of experienced RNs from other facilities across the country, pre-trained travel RNs who’ve been seduced onto full-time jobs after finishing their contracts (I was one of these), and PCU/PACU/telemetry RNs who are excited to move to the ICU and learn the ropes. The latter group requires a hell of a lot of attention before they’re ready to be turned loose on patients.

When I entered the world of the ICU, I was a new grad, fresh off the NCLEX. I knew I wanted to work ICU, and I had done a lot of high-focus work in school to get there, but I was in absolutely no way prepared to actually provide critical care. I don’t know why they hired me—I probably smelled like amniotic fluid and fresh hay, sitting across the desk from the manager with my incisors clamped together and my lips peeled back.

As it turned out, they were desperate. A mass exodus of nurses from their MICU had made conditions very tight there, and I suppose everyone figured it would be easier to foist off the low-acuity pts on a clueless tottering foal of a nurse who probably wouldn’t kill them than it would be to suffer through another month of catastrophic short-staffing. And, I mean, I’m pretty good at making competent faces.

Fortunately, I had excellent preceptors. I sat through two weeks of class, then another week of computer training, then started two weeks of precepting—following an experienced nurse through the care of a single pt, slowly learning the ropes and getting used to all the drips and rhythms and schedules and reports. At this facility, new nurses are precepted for up to three months; at my initial facility, I had two weeks on days, one week on nights, and then a full pt load. I don’t know how I managed not to kill anybody.

I probably did kill some people. Not immediately, but by providing less-than-competent care that didn’t give them the foundation they needed to heal. I over-sedated my pts—to be fair, we all did this—and I often ended my shifts completely confused and with so many chores left to do that I was the terror of the day nurses who had to follow me. I was Not A Good Nurse.

So precepting is really important to me, and I came to work early because I knew I would be teaching someone how to ICU today.

Her name is Maycee*; she is tiny and energetic and has the cute kind of freckles that speckle the bridge of her nose (unlike my all-over sepia dapple that looks like an old-fashioned Instagram filter of a nasty crime scene under blacklight). She has only ever worked telemetry until now. She’s quite smart and used to hard work (tele/progressive care nurses are some of the hardest workers in the hospital), and so I didn’t feel too overwhelmed when they told me we’d be caring for two pts instead of the traditional precepting one.

This is actually an intense load. You can’t just do anything—you’re explaining all of it, the principles behind it, the rationales for your actions, the processes you used to arrive at your decisions, the whole time. You have to ask leading questions and see if your preceptee can follow those routes on their own, which means setting up a decision situation, prompting the preceptee with a question, and taking the time to gently prod and guide them until they answer the question on their own. It basically doubles the time anything takes, which means that taking two pts is an absolutely mind-blasting time-management gauntlet.

One pt was a desperately ill pt with liver failure and sepsis who had, before being intubated, said that he didn’t want to be intubated for more than four days, and who was now on his fifth day with no family members to follow up on his wishes. The other had chronic worsening respiratory issues and hadn’t wanted to be intubated at all, but had been found down by a neighbor who didn’t know his end-of-life wishes, so he’d been tubed and brought in by the EMTs and was now in full-code hell waiting for some family members to get back to us and let us put him on comfort-only care.

This has been somewhat of a theme on our ICU lately. It’s discouraging. I hate to imagine being chronically ill, having no chance of recovery, and being forced to stick around and suffer because nobody can speak for me.

By the way, DNR tattoos don’t count. DNR papers, signed by a physician, are good for something if they’re posted where the EMTs can see them before they get the tube in and start CPR… but they aren’t allowed to pull the tube out or, in many cases, stop the CPR once it’s started. If you really don’t want to get beat up before you die, it’s a good idea to get the signed papers and put them just inside the front door, and maybe to get a med-alert bracelet instructing any rescuers to look at your papers and/or call your POA (power of attorney) person.

Our pt was on levophed, which meant his pressure was okay, but his arms and legs were enormously swollen. He was up by nineteen liters of fluid from his admit weight. We diuresed him as much as possible, using albumin between rounds of lasix to suck the fluid back into his bloodstream from his tissues. An hour into the shift, we started a lasix drip. We also had to keep him on a continuous potassium drip, as lasix works by dumping potassium to force the kidneys to dump water as well (in simplified terms, anyway).

At max rate, the lasix got his kidneys up to a break-even point where he was peeing about as much as we gave him every hour, except hours where we gave him antibiotics or literally any other fluid above and beyond his continual IV drips.

Meanwhile, the guy next door required frequent bolus doses of sedatives to keep him comfortable, and was shitting more or less continuously. He weighed a fucking ton, so we were relieved to discover that his room was one of the two-thirds on our unit that has an overhead lift by which we could turn and haul and move him. It didn’t really help a lot with cleanups, since it lifts pts by hoisting the corner-straps of a mesh hammock the pt is lying on… so if you need to clean the pt’s butt, you have to move the hammock out of the way. But it made turns a thousand times easier.

Our liver failure/sepsis guy was really not doing well. His PEEP had to be cranked up; he was so fluid-overloaded his lungs were flooding, and the high doses of levophed provided even more systemic resistance that backed up into the left side of his heart. I’m not actually sure if this is true, as I haven’t fully researched it, but I’ve heard that levophed and phenylephrine in particular contribute to pulmonary hypertension by squeezing the lung capillaries, which causes the same swelling in the lungs that happens in the hands and feet with those drugs.

Either way, I can tell you that a pt on a high dose of levophed isn’t going to be breathing on their own for long.

(The hand and foot swelling comes from the way levophed closes up your peripheral blood vessels, resisting blood flow to those areas so that the blood is redirected to critical organ circulation… but also impeding the return flow of fluid that actually makes it out that far.)

So we had him on a whalloping fourteen of PEEP. I can’t remember if I’ve explained PEEP before, but I am the kind of person who precepts well because I can’t stop myself from ranting, so buckle the hell in.

PEEP stands for Post-End Expiratory Pressure. If you just breathe all the way out at the end of each breath, the little air sacs in your lungs—the alveoli—can collapse at the end of expiration. And because the inside of each alveolus has to be wet and gooey with lung-mucus to allow oxygen to diffuse across the membranes, the walls of those little sacs stick together when they close—especially if there’s lots and lots of goop, ie lung boogers or edematous flooding.. It takes a shit-ton of work to force those stuck-shut alveoli open again, and until they pop open again, they aren’t exchanging any air. It’s better to keep them open in the first place… but how?

As a bonus, if your alveoli are swollen up with too much water, they might stop working properly—in which case you gotta bring that swelling down. Diuretics might work if it’s a systemic overload problem, but if your lungs are just irritated and inflamed, you need to find another way to squeeze the fluid out. If you’ve ever had a sports injury, you know that compression helps a lot… but how are you going to squeeze your lung tissue?

The answer to both of these questions is PEEP. At the end of each breath, a sharp puff of air forced into the lung keeps the interior pressure of the lung juuuuuust high enough to prop open the alveoli, and maybe even force a few closed ones to reopen. And by maintaining pressure on the alveolar tissue, PEEP compresses the swelling, forcing fluid back into the bloodstream so your heart can pump it and your kidneys can dump it.

There’s a problem with PEEP though. And we ran into it almost immediately, as our pt suddenly bombed his pressures and had to be given albumin, then cranked up on his levophed even further. Why was this happening, I asked Maycee?

She pondered this for a while. It’s not an easy concept to grasp, and I was asking her to piece it together on her own. I hinted that it had to do with pressures and pressure imbalances in the thorax, and she worked on that until I could see her brain sweating. At last she ventured: is his heart not making enough pressure?

Yeah, I said. There are three reasons why the ratio of pressure involving the heart might be off. The heart itself might be having trouble generating pressure; the pressure beyond the heart (either in the body or in the lungs, the two areas the heart empties into) might have spiked, making the heart’s normal pressure insufficient compared to the new resistance; or the heart might not be getting enough pressure supplying blood to it. Or a blend of these things—it’s rarely just one.

Had we recently changed any pressures in his body?

Any post-end expiratory pressures?

At that point she got it, and it was amazing to watch the string of lights behind her eyes igniting a trail from one concept to the other. “More pressure in his lungs from PEEP,” she said. “More pressure for his his heart to push against; more pressure to resist the flow of blood back to his heart from his body. We changed the pressure! So can we fix that?”

The answer is complicated. More fluid in his bloodstream would increase the return pressure to his heart, but stood a good chance of never making it back to his veins after the pressure in his arteries petered out, and he was already desperately fluid-overloaded. He had run out of places to put extra fluid; his arms and legs were weeping and taut, his scrotum had inflated to the size of a basketball, and his belly was a distended, thumpable tank of fluid that had oozed from his liver into his abdominal cavity.

And honestly, you can only give someone so much levophed.

So we called the charge nurse and asked if we could hand off the other guy at 1500—the answer was yes—and then called the pulmonologist/intensivist, our brilliant and beloved Dr. Padma, and asked if she felt like tapping this guy’s abdomen.

She agreed with us: we needed to get some fluid off this guy, and a quick bedside ultrasound showed that he had too much fluid in his belly to measure easily just by looking at it. She said she would go finish her rounds, then come back after shift change.

I sent Maycee on an extended lunch break. It’s hard to absorb all the things you’ll see in an afternoon on the ICU if you’re not used to it, and I firmly believe that part of the learning process involves time spent staring at the wall, trying to piece all the memories and ideas together. By the time she got back, it was ten minutes after shift change, and I had the room more or less prepared for the paracentesis.

Dr. Padma set up a paracentesis kit at the bedside, and we watched as she used the ultrasound machine to guide a needle into a fluid-filled pocket of his abdomen, thread a hollow plastic catheter over it, then withdraw the needle and leave the catheter to drain.

The bag that came with the kit filled to its total—a liter—almost immediately. We emptied it, then drained some more, then realized that this was going to continue for some time. So we hooked the catheter up to a wall suction canister, turned it to low suck, and changed the canister every time it filled up.

The fluid was thick and gooey and wheat-colored with a pink tinge. It also foamed as it poured into the canister, forming a thick layer of bubbles at the top that forced us to empty the one-liter canisters whenever they hit 800mL. I explained to Maycee that the foaming came from protein dissolved in the fluid, a common finding in ascites runoff. Albumin—yes, the same protein that we give intravenously to thicken up the blood and draw in fluid from the third space—is essentially the same thing that you get in egg whites, albumen, which means it foams up nicely when agitated.

I pointed this out to Maycee, and added that you could probably make a decent meringue out of the stuff. She tripped over a gratifying dry-heave and then spat in the sink. “That’s fucking gross,” she said, the first time I’d heard any real language out of her, but her tone of voice was not one of censure.

I mean, you probably couldn’t make meringue out of it. Any decent cook can tell you that any kind of lipid or protein impurity in the albumen can keep the foam from locking; additionally, the acid-base balance of ascitic fluid is more likely to be alkaline than acidic, which means you’d need a lot of cream of tartar to make the foam stable.

Either way, the gates of gross stories had now been unlocked. As we removed liter after liter of fluid from his abdomen—we totaled at nine and a half liters—she told me about a pt she’d had once with severe osteomyelitis in a leg-bone exposed by rotten diabetic flesh, who refused amputation until the doctor reached into the wound and squished the bone audibly, pointing out that it felt like soggy Triscuits.

I told her that one story about the guy and his mother and all the cats, and she called bullshit, which is an appropriate reaction to a story that grim (I will probably never have another story to rival it), but I texted my coworker from that night: “Hey, remember that one guy and his mom?”

Thirty minutes later she responded: “FUCK YOU WHYD YOU BRING THAT SHIT UP AGAIN”

“But you remember it, right?”

“Uh I’m carrying that smell to my grave. How’s your week going, stinky oatmeal?”

The weird thing is that we actually do talk about this almost every time we hang out. We get a bloody mary each and order a thing of garlic cheese fries and sit there picking at the gooey stuff, talking about that guy intermittently between gossiping about coworkers and bitching about administration. I don’t know what we hope to unearth about it, or what draws us back, but in some ways our friendship is about that guy. We’re still working on it.

We finished the paracentesis and Dr. Padma retrieved the catheter. In its wake the insertion site continued to ooze copiously. His blood pressure gained by twenty points within thirty minutes, and we started titrating the levophed down. We administered intravenous albumin again, and shortly after that deep wrinkles appeared in his feet as the swelling started to recede.

A short-term fix. We’d just reclaimed his abdomen as a reservoir for extra fluid; he was still weeping internally. But it felt nice, and it gave Maycee some visible indicator of the pt’s improvement.

The charge nurse appeared in the hallway and beckoned to Maycee. “We’re putting in a trach and PEG down the hall,” she said. “You should come see this.” I waved her off and wrapped up the shift while she and the other preceptees crowded around my abd guy’s bed, watching the doctors attempt to open a hole in his neck and one in his belly for breathing and feeding on a long-term ventilator in a care facility.

He’s actually getting… not well, exactly, but better. His hemorrhagic necrotizing pancreatitis seems to have turned around, and while I’m sure he’ll never have full pancreatic function—or, at this point, full neurological function, as he barely responds to questions and commands—he doesn’t look like he’s going to die of this anymore.

At this point, it’ll probably be pneumonia that gets him. That’s what usually gets people on long-term vents.

They did not have much luck with the trach, although the PEG went in easily enough. He just has weird anatomy. It will need to be done surgically.

I barely recognized him when I poked my head in. His hair has grown a lot, and he’s grown a full beard and then had it shaved. The distribution of weight in his face is really different. You can tell, now that the swelling is down, that he’s not a tall man. As they cleaned him up after the trach attempt and let him come back around, his eyes opened and he looked around the room: a human expression of bewilderment, a hint of comprehension, a glimpse… I regret, now, that I hoped he would die. He didn’t seem to be in much pain, despite someone having just literally slit his throat. He looked uncomfortable, but who knows what discomfort and pain mean to him now?

I wonder what his life is going to be like from this point on. I wonder if he’ll ever really wake up. I wonder how much brain damage he sustained during his intense illness, and whether the dialysis and the tube feeding and the tracheostomy will give him some quality of life. It’s entirely possible. It’s also possible that I’ll never know.

When the night nurse came on, he flipped his shit because we had forgotten to change the propofol tubing at 1600. Because propofol is suspended in a lipid solution, we change the tubing every twelve hours to keep it from getting goopy; I had completely forgotten. I didn’t feel like the flipout was completely appropriate, though. He browbeat Maycee when I left the room and told her it was unacceptable to forget to change the tubing, which is a bit much considering that she didn’t know the rules on propofol tubing—it was entirely my fault—and that we were now three hours late on a non-critical task with a pt we’d spent all day struggling to keep alive. Then he cornered her into performing a full bed bath on the pt with him before she left.

Well, part of a bed bath. He’s notorious for this: you give report to him, and he’ll try to keep you until 2030 as his own private CNA, bitching at you the whole time. I hooked Maycee by the elbow, gave the night nurse a frosty look, and dragged my preceptee off to the break room to clock out.

She looked exhausted, excited, ready for a few hours of sleep and another shift tomorrow. She doesn’t even seem upset at the prospect of spending another day in my tutelage.

I think she’ll do well.

Week 8 Shift 1

By the time I got back, my DKA/wannabe escapee guy had not escaped, but had made everyone on the unit so angry they wished he would. His nonstop bitching and creepy remarks, combined with his gross treatment of his girlfriend and his frequent not-jokes about how we should just let him shoot up because he was going to anyway, had really not endeared him to any of the staff.

When I arrived, he smirked at me, then informed me that he would be leaving at 0930 whether I wanted him to or not, and if I had any shit left to do for him I better get it done in a hurry. And that he would have a long list of breakfast foods from the cafeteria, but didn’t want to stay on the line and wait to order, so he would just tell me and I would have to call down and order for him. When I told him he could either order his breakfast or go hungry, he shrugged. “Fine,” he said. “I have my own insulin, I’ll give myself a dose and go into hypoglycemia, and you’ll get fired.”

I have honestly never had a pt so openly threaten to harm himself to manipulate me. “I’ll give you IV dextrose,” I said, “and your insulin will mysteriously go missing while you’re unconscious, and you’ll wake up just fine except you’ll be hungry. Here’s your phone, you decide if you want breakfast or not.” Then I went and reported all this to the charge nurse and documented it.

His girlfriend met me in the hallway a little later. I won’t tire you with the entire conversation—it was very long and wandering and difficult to listen to—but the gist of it seemed to be that she wanted to stay in the methadone program and get clean. If she stayed with him, she said, he would never let her get clean; but if she left him, who would take care of him?

“I think you’re right,” I said. “He’s gotta find his own rock bottom, and hope that it isn’t a grave. If you want to get better, you’re definitely going to have to get away from him, and you’re going to need some professional support while you’re remodeling your life.”

“But what if he dies?”

“Then he dies, chickadee. Maybe you won’t die too. When you’re drowning, you gotta kick off your shoes.”

I know there’s not much hope for her. But I really hope, if she dies of this, she’ll at least die without that asshole being rude to her the whole time.

At any rate, I got that dude’s discharge paperwork done in record time. I am already a lightning discharge nurse, which usually helps out my pts who really really want to get home in time for the game, but I had him ready to go by 9:15. I cornered the hospitalist that was seeing him and told her she could either give him discharge orders or sign his AMA*, that I had everything ready to go for him to leave, and that the only medical reason I could see to keep him was that he’d threatened to inject himself with insulin so I’d have to order his breakfast. We could have stretched that into a suicide threat, but honestly, it wasn’t. And there wasn’t much else we could do to help him.

(*AMA, in this case, has nothing to do with reddit—it just means Against Medical Advice.)

If I seem callous about this, know that I have zero interest in whether a person is addicted to a substance—it’s a disease we understand very little about, and one that destroys lives as ruthlessly as any sepsis or stroke. The mental health issues that so often accompany addiction, those I have even more sympathy for: my family is not without its comorbidities, and I have seen firsthand over many years the impact of addiction, bipolar disorder, major depression, personality disorders, and post-abuse trauma, all untreated and all devastating. I see this shit every day on the ICU, and it’s a parade of tragedies that never fails to make me sick with frustration that I can’t save them.

But there are, among the tragedies, people who victimize others in their tragedy. Just as it’s hard to feel fully sympathetic for a person who survived horrific childhood abuse and goes on to abuse their own children, it’s very difficult to feel that sympathy for a person whose lifestyle is so self-destructive and so poisonous that they won’t let their loved ones escape the same trap, and whose attitude toward the people they’re hurting and the people who care for them is one of loathing and snide gloating.

And there are people who are offered the help and support they need, and laugh at the people who offer and how disappointed they are when those gifts are refused.

Not a lot of sympathy, no. I was glad to see him go. He asked if he could keep his IV “for convenience.” I gave him an incredulous look and then “accidentally” pulled his IV out with one sharp yank.

“Oops,” I said. “Usually I leave those in until right before discharge. Oh well, you’re leaving soon anyway.”

He and his girlfriend sat in the room, rolling cigarettes from the tupperware of tobacco, until I escorted them to the door. On the way out he joked that maybe he’d offer me a ride in his truck sometime. I couldn’t even feign a farewell smile.

Meanwhile, next door, a coworker of mine landed a pt with Evans Syndrome, a rare autoimmune disease that causes your body to eat all its blood. The pt was acutely psychotic for some unknown reason and lay in bed screaming as if being burned with hot irons. Pain medication did nothing; anxiety medication helped. He couldn’t tolerate anything touching his body and ripped off his ECG leads and clothing constantly. We didn’t bother putting in a foley, but any time he needed to urinate, he would start screaming extra loud and rolling back and forth, cursing and wailing, until he finally let it all loose and soaked the bed/floor/wall/everything in the room.

The second time this happened, I was helping hold his legs down while he struggled to kick and bite the nurse, and the dam broke just as he started bucking. The ensuing arc of piss undulated across the room like one of those floppy-hose kids’ toys that squirts water at shrieking babies in the back yard. He got himself in the face pretty good, and it shut him up for a minute, his whole face contorting in puzzlement as he smacked his lips and snorted. Then he saw that he’d peed comprehensively all over the other nurse—he only got my arm a little—and started laughing hysterically until he passed out from more Ativan.

Meanwhile I had a second pt to take care of: a woman whose uterus had been removed earlier this year for cervical cancer, whose extensive internal scarring had formed massive adhesions and twisted her small intestines until pieces of them died. She’d undergone immediate surgery to resect the dead bowel, and been in pretty good shape afterward. Yesterday morning, however, she had become confused, then gone into respiratory distress. Early in her confused state, she’d pulled out her feeding tube, vomited, and possibly aspirated before finally being intubated and sedated. My job, today, was to support her through what could either be the return of bowel ischemia, or the beginning of ARDS.

She required lots of fluid support and plentiful pressors. She could hardly tolerate turns, and her urine output was minimal at first, though it picked up as we started Lasix to get rid of her sixteen liters of extra fluid. She was in Tiberius’s room, which felt very strange, because her family was also delightful and friendly and religious.

By midafternoon it was pretty obvious that she had ARDS. What’s more, her intestines started to pick up slack and give me some really gross noises, which is fantastic to hear in a pt whose guts are still stunned from massive injury and surgery. But man, that ARDS was not treating her well, and we kept cranking her fiO2 and PEEP up to keep her ventilated… and, eventually, oxygenated. It takes a lot for your lung tissues to stop exchanging oxygen well. We finally found a nice plateau at a whalloping PEEP of fourteen. (Five is the average. Ten is what you get when you’re ARDSy. Twelve is considered a bit much.)

The rest of the day was a matter of balancing her pressures with her body’s ability to tolerate pressors. Levophed made her arms and legs mottle deeply and turn icy cold, and didn’t have as much impact as I would have hoped on her blood pressure. The PEEP was making it hard for her heart to fill and squeeze effectively, which dumped her BP, which in turn made it difficult for her body to get rid of the excess fluid that had accumulated in her body.

There are three spaces in your body where fluid can hang out. Well, I mean, there are lots of places where fluid hangs out, but there are really only three we care about when we’re thinking about fluid overload and blood pressure.

One space is inside your cells. They’re just little water balloons, right? Some DNA and RNA and a mitochondria or two floating around in there, maybe some enzymes doing heavy lifting, some proteins grabbing shit and gluing it together… and, you know, water. This part is pretty boring to me unless a) my pt has been exposed to cyanide or b) my pt is going to need some kind of insulin fuckery to move sugar or potassium into their cells.

Another space, which I am HIGHLY obsessed with, is the vascular space—your actual bloodstream. Water, albumin to thicken the water and keep it osmotically the same as everything else, blood cells, dissolved gasses and sugars and shit… but mainly, blood pressure. Blood volume. If you’re bleeding out, the first thing I’ll give you won’t be blood, it’ll be saline; it’s the same salt concentration as your blood, and it will expand your blood volume so that the blood cells you have left can actually get around and your heart has something to pump.

Remember: if you ain’t got pressure, you ain’t got shit.

But there’s a third space: the areas between the cells, the structural nooks and crannies of the flesh. And when you’re massively inflamed, that space fills up. When your finger gets stung by a bee and swells up, you don’t suddenly get twice as many finger cells—rather, your inflamed cells call out for help, and your body responds by flooding the areas between them with water so that your white blood cells and antibodies can move around more easily and clean up the toxins. Your finger swells up.

When your whole body undergoes systemic inflammation, as with sepsis, that is a whoooooole lot of swelling. And all that water has to come from somewhere—namely, your vascular space. Pretty soon, there’s not enough water volume in your blood for your heart to circulate effectively, and your bloodstream is drying up, and your organs are dying for lack of blood flow while your body happily carries on dumping all its water into your puffy fingers like it’s gonna do any good there.

That’s the basic dynamic of sepsis. And this lady, with her aspiration pneumonia and her fucked-up guts, was septic as all hell. We had boosted her blood volume over and over with fluid boluses, and done our damnedest to pull the fluid back from her third space into her vascular space, but in the end all you can really do is try to interrupt the septic/inflammatory processes with antibiotics and other drugs, support their blood pressure with volume and pressors, and wait for them to pull out of it so you can dry them out again.

Thus, we gave her Lasix. Albumin first, to draw the fluid into her vascular space; then, after thirty minutes, Lasix to diurese her, to pee off the fluid so it didn't overload her struggling heart and increase the pressure and fluid drainage inside her lungs.

It was a long, exhausting afternoon, full of minutiae and sweating into my eyes. Her mottled flesh continued to spread, and her edema increased visibly from the beginning to the end of my time with her. I don't have a good feeling about her outcomes. I suspect she will never be stable again until she's dead.

Meanwhile, another crazy substance-abuse pt was admitted down the hall. I could hear him screaming and cursing even while I was turning my lady, and one of the other nurses poked her head in to ask if I still had the key to the velcro restraint box (I did not).

Things seem to come in waves on the ICU. We’ll get a bunch of STEMIs in a row, then a bunch of GIBs, then a bunch of ARDS. In reality, it’s probably just a normal distribution of all the shit that can go wrong in a decent-sized city; to the endlessly superstitious nurses on the ICU, it means that once you get two pts with similar symptoms, you are destined to get at least two more in the next week or so. This happens often enough to turn our confirmation bias into rock-solid religious conviction. Not looking forward to the next round of crazy.

But who knows? I could just be destined for admit after admit with stuck gut and sepsis. Or I could be too tired to think straight. I suspect the latter is more accurate. Time to pass out.

Week ???? Shift ???????????

Some things I forgot to mention last time:

At 1100, shortly after I received the abdomen pt, I called up the charge nurse and politely requested to have him made 1:1. I don't ask for this often, and pride myself on my ability to balance multiple high-acuity pts safely. But part of this ability involves my recognition of when the load is too heavy for safety-- anyone can pretend they have things under control right up until a pt codes-- and when I realized this pt had hourly insulin checks, constant potassium replacements from an electrolyte replacement protocol (the intensivist declined to start a potassium-containing IV fluid despite refractory K+ levels below 2.8, the cutoff point below which the heart starts to starve and freak out, on the grounds that his renal failure would cause his K+ to skyrocket eventually), q2h labs, and 200mL+ output every hour from his NG tube (thus the potassium loss: stomach juices contain a lot of K+)... I had also just started levophed to pull his blood pressure up, couldn't find peripheral pulses in his feet, and was calling the RT in frequently to handle his ventilator-bucking. Yeah, at this point I decided he wasn’t going to be compatible with the high-need lady next door on bipap, no matter how clean she was now.

I was pretty sure he’d code by mid-afternoon.

The charge nurse came in, looked around, and agreed with me. So after 1100 he was 1:1. This came in really handy when the GI surgeon took him down for that washout.

So for the next couple of days, he wore me out. His open abdomen wept constantly through the drains in the intestine-containment bag, and every thirty minutes he required a full dressing change just to control the flow. His insulin infusion had to be cranked up from one algorithm to the next, as higher and higher doses failed to control his wild hyperglycemia. Worse, as I finally caught up on his blood sugars the next morning, his anion gap stayed wide open—the acidosis continued, and although his potassium finally caught up and began to rise as his small bowel obstruction stopped backing four liters of stomach juices out of his NG tube every day, the problem was clearly not a sugar/insulin imbalance.

Anion gap acidosis has a number of possible sources, although insulin deficiency is probably the most common. A few of them were addressed in that nephrologist’s note I quoted the other day. Another occurred to me during my camping trip this weekend, as I was studying for the CCRN test I took today (AND FUCKING PASSED YESSSS I AM A CCRN NOW). This guy is an alcoholic, and had been sick for a little while, homebound. What if he got into some alcohol that wasn’t drinkable? Specifically, methanol? It would explain some other major things, like the encephalopathy and his eventual failure to maintain pupillary reflexes.

Man I got no idea. I haven’t actually taken care of a pt with methanol poisoning, so all my knowledge is book knowledge. Methanol, aka wood alcohol, is an alcohol much like ethanol (booze), except that it turns into formic acid in your body, destroys your eyesight permanently, causes brain swelling, and tends to result in horrible death. I’ll have to look that up when I get back to work on Saturday.

Anyway. He stayed very high-acuity for the next few days; I was 1:1 with him the next day, and the day after that I was first admit, but ended up not admitting because the only person who came up from the ER was a telemetry overflow. He was one of those pts who isn’t panic-level crazy, but whose workload nurses describe to each other as “steady.” Basically, there’s something to do at least once every ten minutes, some of these things taking as long as twenty or thirty minutes and requiring multiple RNs or the help of a CNA, and you spend very little time charting because you’re constantly scanning medications or taking blood sugars or turning or changing dressings or titrating drips.

In this case, about halfway through the second day, the intensivist ordered lactulose enemas to be given every four hours, in hopes of stimulating his bowel to move. I took extreme issue with this because I could SEE the guy’s intestines and they were obviously too swollen to twitch, let alone move stool effectively, but considering that his colon was relatively un-irritated per report of the GI surgeon and the enemas were only about 250mL volume (we often give 1L-2L enemas!), I figured it couldn’t hurt. And sure enough, after the second enema he dumped a decent handful of mucoid stool, although his small intestines were obviously still not moving.

How did we administer these enemas? The traditional way involves turning your pt on their left side, sticking a tube up their rectum, and draining a bag of fluid into their butt to get the shitslide cookin’. Turning this guy onto his left side would have been… tricky, so instead I pulled the rubber tube off the business end of a foley catheter, lubed it up a bit, jammed it up his butt via the “lift balls, grope for anus” method, and inflated the balloon with a syringe of saline. Then I mixed up the enema, drew it up into a giant Toomey syringe of the kind we use to instill fluids into a GI tube (it holds about 60mL at a time), and flushed it all through the rubber hose into his colon. Between flushes I clamped it off with a large hemostat, the kind we use to clamp chest tubes shut. An hour or two later he dumped the full enema, still clear, into the bed. Time to start over.

Turning was tricky. Any time we moved him, he would grimace and his blood pressure would skyrocket—even though he was heavily sedated and receiving a pain med drip, he was clearly having a lot of breakthrough pain. His blood pressure tended to run dangerously low whenever he wasn’t in pain, though. So I would dose him with a huge bolus of fentanyl, wait about two minutes for it to kick in, watch his blood pressure start to bomb (watching in real time through an arterial line), and then do all the turning and washing and dressing changing and whatnot.

Ventilated pts also get their teeth brushed or their mouths swabbed and suctioned once every two hours, usually right before we turn them so there isn’t a drool river when we’re moving them around every two hours. 

The whole time, we were hunting desperately for someone to make decisions on his behalf: a family member, a designated power of attorney, anybody. His kidneys weren’t pulling out of their tailspin, and the buildup of nitrogenous wastes in his body wasn’t doing him any favors. Before we made the huge step of initiating dialysis, though, knowing that this would be a long healing process with a huge amount of involved and intensive care, it would have been really nice to know if he’d have wanted it.

This being a weekend, and this fellow being a member of a specific healthcare group that has its own social workers and discharge nurses that aren’t available on weekends for whatever goddamn reason, I found myself doing most of the work of contact hunting. I called his job and, without being able to give them any details over the phone, asked if he had any next-of-kin numbers. None of them worked. I called his home phone, got his roommate, learned that he had a daughter he had only ever referred to as “my daughter;” received a phone call from a coworker of his who had heard he was out sick, and found out that he has a landlady who “might know somebody;” called the landlady and learned that he had family somewhere in a Middle Eastern country “who don’t speak any English and I don’t know their names;” and was finally suggested to contact a religious leader of his community, who might have access to lineage papers.

By the time I got to that point, it was Monday morning, and the social workers were back on the job. So I spent about an hour pushing them over the phone, giving them a full report of everything I’d done to seek contact, and signed off on his “call the family” duties.

Meanwhile, down the hallway, the drowned kid circled the drain for days. His lungs were torn to shreds by the lake water; his anoxic brain injury caused him to start seizing for hours at a time; his mother went completely insane before my eyes and descended from “horrified and grieving mother” to “crazy woman in filthy clothing laugh-sobbing in the end of the hallway all day and all night.” God, we all felt terrible for her. She threw a shoe at the palliative care people when they came by. 

He went into a rotoprone bed, as I think I said before, and coded in it. A rotoprone bed is no minor thing in ICU practice. It’s like a huge padded coffin/cradle into which a pt can be packed, then wrapped tightly in cushions and panels and straps, then rotated until their face is hanging downward so their lungs can drain. Once they’re proned, we open the back of the bed and let them lie there, gently swinging back and forth with their belly facing the floor, letting their lungs stretch and drain and slowly recover. It’s very effective when used early, and was originally marketed for H1N1 support, since young pts who survived the initial respiratory catastrophe of that strain would recover easily enough in a week or two.

Now we use it for ARDS, acute respiratory distress syndrome, which can happen for many reasons ranging from pneumonia to aspiration to pancreatitis. In ARDS, the lungs become so inflamed that their tissues turn thin and stiff, they can’t exchange gas well, fluids weep into the air sacs, and even the blood vessels lose their pliancy and become hard and resistant to blood flow. 

We use a lot of things to treat ARDS. Paralytics can help reduce the pt’s inclination to fight the ventilator, and minimize their oxygen usage; Flolan (epoprostenol) is a ruinously expensive inhaled medication that dilates the blood vessels of the lungs to allow improved blood flow; chest physiotherapy can sometimes be used to help break up secretions and move fluids around; and, of course, antibiotics and steroids and protective settings on the ventilator to prevent lung damage. And PEEP.

Remember how a bipap mask adds a kick of pressurized air at the end of the breathing cycle to keep the airways (large and small) open? PEEP (positive end-expiratory pressure) is similar to that. Cranking up the pressure helps force fluid back into the veins, keeps the air sacs open, and increases the pressure gradient of air vs blood so that air exchanges more effectively across the membranes. Usually ventilation (CO2 shedding) is harder than oxygenation, but in ARDS pts often have oxygenation just as bad as their ventilation. 

I’ve seen ARDS fought effectively. I cared for a pt once who was very young, got a nasty pneumonia, spent days and days in the rotoprone bed, and was eventually transferred to the local children’s hospital to receive ECMO—extracorporeal membranous oxygenation, in which blood is drained from the body, oxygenated through a membrane, and pumped back into the body constantly. She ended up doing well, and sent us a letter about a year later to let us know that she had not only survived, she had recovered enough to walk across the stage at her graduation.

The drowned kid will not be so lucky. Even if his lungs manage to recover from the lake water problem, his brain is completely fucked from the continued hypoxia. We are, essentially, buying the family time to say goodbye.

Which is a victory, sometimes. If we define death as failure and any kind of life as success, then pretty soon our successes are often hollow—we have quite a few pts who end up suffering for a very long time and being shipped back and forth between the hospital and a long-term acute care facility—and our failures are nearly constant.

You have to look for other definitions of success and failure, here. Sometimes our victories are good deaths. Sometimes we work our asses off day and night to make sure a pt is comfortable as they’re dying. Sometimes we finally manage to talk the family into letting go; sometimes we struggle to win them the few days they need to come to terms with their loss. Sometimes we squeeze enough time to let the plane land and the taxi speed from the airport, so that the kids can be there when their father dies. Sometimes we wash our hands of a code and catch our breaths, and the corpse cools in the room while we go back over the entire crisis and realize that we did everything right and they died anyway. But it’s still a victory, just as all these others are victories: we did everything right.

But they died anyway.

And sometimes we practice our skills on a pt who has made every possible bad choice and is dying of their bad choices, knowing that our care is futile and the resources we spend are wasted, but knowing that when the next pt comes in needing that unusual procedure, we will be that much fresher in our practice. That’s a victory, if you squint.

And sometimes we fight tooth and nail to save them, and care about them, and care so deeply about their survival that when they die anyway we are all devastated and we go out and drink and wish we could have done anything, one more thing, to save them. Which, I don’t know, might not be a victory; but it feels like something more important than a defeat. It feels like a connection. It feels like we have successfully recovered our humanity, which we often hang on the break room wall next to the memo notice sheets and the spare stethoscopes, so that we can dig in a pt’s guts without cringing and accept verbal abuse without snapping and look death straight in the face without blanching. It’s inconvenient, but it’s easily lost, and even though it’s selfish we value those moments of realization that we aren’t as dead inside as we pretend to be.

Which is to say: when the drowned kid died, my last day before I went on that huge long camping trip and didn’t post for a while, we were all devastated. His mother cried like an animal, gagging and groaning and clawing at her arms, and we all twisted our mouths and ground our teeth and remembered that we were people and wished we weren’t.

Rachel went home again. Her younger child’s birthday is coming up.

That same day, the last day before camping, I sent my open abd guy down to have his belly incision revised. They will slowly close it until at last his intestines are all contained, giving him time for the swelling to diminish between each revision. Then, because he wasn’t expected back up before my end of shift, I took two more pts: a comfort care pt in his thirties with Huntington’s, who was starting to lose his ability to swallow his secretions and was choosing to go home to die rather than move forward with a tracheostomy, and an older fellow with severe hearing loss who had come in for a very mild GI bleed from an ulcer in his stomach.

The comfort care pt’s case was relentlessly sad. His young wife is pregnant; he is not expected to live to see the child. He declined to make a video for the baby, saying that he didn’t want his son to see him like this. His family are rollicking good-ol-boy country folk, and they all sat in his room picking on him affectionately and watching Pawn Stars. They were delightful; they had faced this monster directly, and chosen not to be destroyed by its inevitable rampage, and as a result they were wonderfully supportive and caring. They helped move his cramped arms and roll him gently when he needed to be repositioned; they joked that his stubble “looked like wanderin’ pubes.” They ate five boxes of Fruit Roll-Ups in the room (making me crave Fruit Roll-Ups), and tirelessly suctioned his mouth with a soft plastic tube so he wouldn’t choke.

We tried out atropine drops to dry up his mouth, and they worked fairly well, although he still needed some suctioning from time to time. He was just waiting for the hospice group to pick him up in the morning and bring him home, where he can spend the rest of his life in comfort, surrounded by family. He got the shittest deal on the table, but I think he’s choosing the best possible option with it.

The GI bleed old guy told me about gladiator diets (beans and porridge, with burned plants to provide magnesium?) and house paint (never just use flat white, it looks too bare!) and nail storage (lots of yogurt containers!). He was advanced from a clear liquid diet to a full liquid diet, and delighted in his tray of four different kinds of soup instead of “all that sweet stuff they’ve been trying to trick me into eating.” He called me darlin’ and ma’am and Nurse Elise. He was an absolute doll and I wish all my pts were like him. Plan was to send him home the next day.

The next day I left for my camping trip, and haven’t been back to work yet. The trip was wonderful—I moved into a hammock by Lake Crescent, out on the peninsula, one of the prettiest places I’ve ever camped—and then I came home, finished my studying, took my CCRN exam, slept for a full day, and went to Cardiology Summer School today (first of three Fridays spread throughout the summer, lectures by a popular nurse educator in the area). Tomorrow, I go back to work.

I did stop by and check on my open abd guy. He is still alive and seems to be doing well, though the dialysis nurse was in his room setting up shop when I poked my head in. I didn’t see his abdomen, though. Maybe it’s closed by now. I will check his chart tomorrow and see what all has been going on while I was eating hot dogs and smores at the lake.

And I had my ninety-day review at this facility (I worked there for three months as a traveler before hiring on full time). My manager said there have been absolutely no complaints about me, which makes me pretty giddy, but added that the charge nurses were surprised by how easily I fell asleep on my nap breaks and how often I spend my breaks napping.

I really don’t know what to say to that. I’m fucking exhausted all the time at work and I sleep like a dead rock every chance I get. I just kind of stammered something about being ex-night-shift and wandered away. I thought break naps were one of the crucial characteristics of the nursing profession in general? Maybe I’m just lazy. That is a very real possibility.

I wonder if I’ll get my abd guy back tomorrow. I guess I should head to bed soon, since I have to be up in six hours. Shit, I think I figured out why I nap on all my breaks.

Saturday, July 18, 2015

I have no idea what week this is but it's Friday

I had Friday off. I spent it on meaningless bullshit and faffery, for the most part; my sister and I had a meeting with her new guidance counselor to schedule some aptitude testing and discuss tutoring/counseling options for the next week. She’s settling in well—learning things like “how to make a sandwich” and “how to use a bus.” I feel like I’ve been working almost every day since she arrived.

Saturday morning I assumed the role of first admit nurse, then took report on one pt, a frequent flyer who has been notorious for her poor adherence to heart failure medications and home bipap use. She is cared for almost entirely by her devoted son, who does a fine job except that she refuses a lot of care, and hits. Or did. Last time she was here we put her on a horse-tranquilizing dose of Paxil, and this time around she’s been fairly pleasant and cooperative.

Her son is a very gentle sort, a little bit Bob Ross and a little bit hapless victim, so I was quite surprised to hear him call the Paxil her “anti-bitch pills.” He said it in such a self-deprecating way that it took me a moment to realize he was making a joke. I suspect that his life has changed a lot for the better since we started her on the meds.

She hadn’t been handling her bipap well lately, though, so not only had she collected lots of carbon dioxide, but her heart failure was really acting up. Explaining this will take a little bit of pathophysiology, so buckle in.

The old ICU saying goes: if you ain’t got pressure, you ain’t got shit. Blood pressure is so crucial to survival that we’ve even changed our CPR methods to emphasize compressions—pressing on the heart to maintain some blood pressure—and decreased the whole rescue-breathing thing to “meh, if you have time, but don’t stop compressions.” Oxygenation and ventilation (remember, ventilation refers to airing out the carbon dioxide in your blood) are important, but without pressure, you can’t get the oxygen to the tissues or return CO2-laden blood from the tissues. And your body can deal with a little low oxygen or high CO2 (your blood keeps a huge amount of oxygen after its first pump-through!), but not with a loss of pressure.

But what if you have too much pressure? High blood pressure makes tiny tears in your veins, which scab and scar and become susceptible to clots. Not as damaging as high blood sugar, which is like knives in your blood, but it will definitely tear you up inside. And if your blood pressure gets too high, you might blow a blood vessel in your brain—you will typically feel a headache only once it’s too late to do more than contain the bleed. High blood pressure is a silent killer.

What about if you have a pressure imbalance? That’s what’s happening to this lady. She has an obstructive breathing disease, with nasty sleep apnea that traps air in her lungs while she sleeps. The pressure in her lungs grows and grows as her body struggles to overcome her collapsed airways, until finally the air escapes with a whoosh and she can start the process of gasping for more air. There’s a reason people with sleep apnea are always tired and shitty-feeling: they spend their nights suffocating.

Meanwhile, the right side of the heart, which pumps blood into the lungs to be oxygenated, has to pump against a huge amount of pressure. As the pressure grows in the lungs, the blood has to be squeeeeeezed in with incredible force, and eventually the right side of the heart blows out like a stepped-on water balloon, becoming weak and floppy, and struggling to empty itself so more blood can return from the body. So blood backs up in the body, and the water that would normally be peed away by the kidneys just squeezes out into your tissues instead. Usually the lower part of your body first. People with right-sided heart failure get giant, swollen ogre legs, which get so stretched out they form big bubbly scars where water is tucked away, never to be returned to the bloodstream again.

One of the most crucial treatments for this is a diuretic, a water pill that convinces the kidneys to pee extra water away while it has the chance, since it’ll take a lot more work for the body to get water all the way back around to the kidneys again. So if you are, say, a grouchy old lady who hits nurses and doesn’t believe in taking her pills, pretty soon you’re retaining more water than New Orleans in hurricane season. And if your bipap is lying in a drawer while you sleep, your CO2 rises, and you become too groggy from CO2 poisoning to wake up and breathe.

CPAP and BiPAP can help a lot with this too. CPAP gives a little boost of air pressure to keep the airways open; BiPAP uses two different pressure levels, one for inspiration and the other for expiration. The increase in pressure is absolutely minimal compared to the whole “lungs stuck shut” pressure differential, and the overall result is that the lungs stay open, the volume of air (and thus the ventilation of CO2) is maximized, and the pt is wildly uncomfortable for the first little bit and then suddenly realizes they can breathe again. Nobody wants to wear a mask over their face… until they realize they can finally sleep like a real human with the mask on.

So she came in to the hospital nearly comatose, swollen up like a marshmallow in the microwave, smelling like the inside of a hobo’s shoe. I have a personal thing about stinky pts: I want them to be clean. I will make them clean if it kills me. Under no circumstances short of immediate, life-threatening danger will I allow my pts to lie in their filth with a baguette’s worth of yeasty crust on their scalp and a gunt-tuck full of smegma the texture and color of butterscotch pudding. If you come into my merciful care and your vagina is oozing all-natural Cheez Wiz, you had better get ready to spread.

I shoved a bedpan under her head and shoulders and soaked her in warm soapy water up to the ears, periodically sloshing more over her scalp and dumping the detritus in the toilet to be replaced with more. Once the water started clearing up, I emptied half a bottle of chlorhexadine mouthwash into the next round, and let that seep through the microbial rainforest of her ratty hair until the tectonic plates of yeast-plaque gave up and let go. The scalp underneath was raw and pink and looked like a fresh pork chop with a little incidental gray hair growing out of it.

All her folds I scrubbed, with the help of the long-suffering CNA, lashing the creases with antifungal powder and lining them with folded absorbent pads. The less said about her lady parts the better, but I can’t imagine how anyone could have dustflaps that yeast-eaten and not cry like a kicked dog every time they took a piss.

Her son came in near the end of the scrub-a-thon and gaped. “She never lets me wash her,” he said. “The last time I tried, she hit me and said she’d be dead before anybody washed her hair again.”

“Well, unconscious,” I said, and added that if she really wanted to stay filthy she was going to have to make sure she took her medicine so she wouldn’t become unconscious and be at the mercy of nurses again.

Then I got a call from the charge nurse: a rapid response from upstairs would be my admit, an alcoholic gentleman who had come in with pancreatitis three days before, gone into massive withdrawal, and then become so short of breath that he was being emergently intubated upstairs.

I knew right away it was going to be a clusterfuck. The intensivist was up to his neck in the drowned kid’s case, and was in the middle of a chest tube insertion that would need to be followed by a bronchoscopy. His acute lung injury was reaching the point where he couldn’t maintain decent oxygen levels, let alone ventilate effectively. Worse, he’d started to show signs of severe brain injury, small seizures that ramped up throughout the day until (right around the time I left) he was in status epilepticus, a massive seizure storm that we couldn’t seem to get under control. Needless to say, if my guy was going to be trouble, he was going to be my trouble.

Naturally, he showed up looking like yesterday’s shit. Blood pressure tanking, legs cold and mottled, foley catheter having drained less than 5mL of urine per hour (we start worrying at 30mL/hr) for the last six hours, nostrils flaring to suck in more air even while the ventilator forced each breath in. His anion gap—a measure of his energy status on the cellular level—was incredibly elevated, along with his blood glucose, which suggested that his sugar was staying in his blood rather than being eaten by his cells. His body was acidotic, which supported that idea—starving cells shit out torrents of lactic acid—but, weirdly, his potassium levels were low.

Those of you who have been following this blog for a bit have already been bashed over the head with the relationship between insulin, sugar, and potassium, but I will explain it again for the new admits. Insulin isn’t a magic anti-sugar substance—it’s just the key that opens your cells’ mouths so they can eat the sugar out of your blood. It also lets them eat potassium, which is a positive anion that keeps the inside of the cell electrically imbalanced against the outside (where negative sodium ions and other such things float around). Between the potassium, which is the electricity that powers the cells’ pumps, and the sugar, which is the gasoline that powers their engines, insulin keeps your cells purring along like that Nissan 240Z pignose you had in college and will never forget.

(I did not have that car. I barely know what that car is. My husband had that car and still obsessively draws pictures of it, rhapsodizes about it, and laments its demise to this day. He likes engines a lot and likes to stay up late at night and look at pictures of old Soviet planes until three in the morning, hurriedly switching windows back to wholesome Miata portraiture when I stumble to the kitchen for a glass of water. This is a dumb derail and I will stop.)

If there’s not enough insulin, or if your cells have become resistant to insulin, your blood sugar will soar as your cells starve. Potassium lingers in the blood, slowly throwing off the balance of positive and negative until muscle cells—especially heart muscle cells—can’t function properly. As your cells rip themselves to pieces, looking for anything they can burn for energy, pouring out lactic acid diarrhea from eating their own garbage, your heart begins to short out and beat erratically.

So it was really weird that he was hypokalemic—LOW on potassium. Especially since his kidneys had started failing, and thus weren’t able to dump any potassium. Even weirder, his lactic acid levels were still fairly low. (I can tell you now, days and days later, that even nephrology was never quite able to pin down the reason behind the rhyme with this one. Actual quote, with warning for medical blather: “Anion gap acidosis. The large anion gap is unexplained by the minimally elevated lactate or phosphorus level. The acidosis is larger than the ABG or serum bicarb suggests since he is currently receiving 180 mEq per day of sodium bicarbonate. Doubt ketosis. Doubt salicylate at this point in hospitalization. Because of ileus, could possiblly have d lacate. No heavy lorazepam (he did have several doses IV) or other propylene glycol ingestion.”)

But all this weirdness aside, I can tell you he was sicker than shit. His abdomen was HUGELY distended and hard to the touch. It’s not uncommon for people with pancreatitis to have swollen, painful bellies—really, that’s usually what brings them in—but this was just out of control. I laid him flat to turn him, and his blood pressure bombed. His ice-cold, mottled legs had no pulses. I sat him back up and he recovered his blood pressure, and I developed a hunch.

Low blood pressure from sepsis isn’t positional. Positional hypotension usually means that either the aorta is so scarred up (usually from smoking) that the heart can’t push blood hard enough to reach the brain when you stand up, or that something is crushing your heart in one position and not in another position. I suspected abdominal compartment syndrome. 

Compartment syndrome is what happens when some part of your body is so swollen that it fills up its entire "compartment" and crushes itself, preventing blood from circulating to the tissue. Compartment syndrome in an arm or a leg can result in losing the limb, and the primary treatment is a fasciotomy: a deep slash that opens the muscle sheath-- the fascia-- so the swollen tissue has somewhere to expand to.

But what if you have massive pancreatitis, and your intestines are so swollen they're crushing all your internal organs, blocking your aorta, preventing blood from returning to your heart, and blocking any blood flow to themselves at all?

One carefully worded discussion with the intensivist-- who was moving the drowned boy into a rotoprone bed, which would rock him gently face-down to help drain his lungs and keep them open-- I got permission to put in a consult by a GI surgeon. "If he's pissed," said the intensivist, "I'm gonna tell him it was the pushy nurse that put in that order." We get along well and are facebook friends, but he's testy when pressed and haaaates being told what to do.

Whatever. Put in the consult with a note of my own-- STAT PLEASE SUSPECT ABD COMPARTMENT SYNDROME-- and within an hour the GI surgeon had cleared his slate and called in the team for an open abdomen washout.

He returned three hours later with his guts still open. A plastic bag contained his bright-red, massively swollen small intestine, sutured to the edges of his incision. Gooey abdominal fluid poured from every crease and seam. His urine output picked up a little, but to this date he hasn't recovered kidney function yet. His legs turned pink again, and his breathing eased. His guts had been crushing him to death.

I had him almost stable by the time night shift arrived. I gave report, helped clean and turn and mop his juices out of the bed, and staggered out of the hospital. I was so tired I slept in my car for an hour before I could drive home.

I will tell you all more about his care and progress tomorrow, and hopefully get caught up completely, as I finally DON'T work tomorrow. For now, I will tell you that there is an actual photograph of his guts posted on my Patreon, and that shit only gets crazier.

Rachel was readmitted that day. She was having sharp pleural pains in her side, and she has a pneumothorax. She's getting another chest tube, but isn't expected to stay long. She's gained ten pounds since discharge and is as sweet as ever.

A forty-five-year-old woman died that day of sudden-onset pneumonia with hypoxia. We are all a little stressed over all these young, incredibly sick pts.
