All right, so welcome back to the Internet Book of Critical Care podcast.

I'm here with Adam Thomas, and we're going to talk about abdominal compartment syndrome.

This one should be a juicy little tidbit for you guys, because I know the last couple have been long.

So this one is quick and to the point.

That compartment syndrome.

We always forget about the abdominal compartment I feel like. And it's one of those underlying sinister causes of badness. So today we're going to cover risk factors and who you need to consider this. How abdominal compartment syndrome presents. How we're going to diagnose it. Of course, all things, treatment and finish it off with some pitfall.

So Josh, risk factors and who actually gets abdominal compartment syndrome? What populations

should we have our antennae up for this? Abdominal compartment syndrome is divided into roughly

two categories. The first one are primary abdominal compartment syndrome. These are folks with

primary abdominal pathology. In the medical ICU, the classic one is severe pancreatitis. Ascides can cause this too. And then in surgery,

you have stuff like trauma, abdominal surgery, retropertenile hemorrhage, and severe alias

and essentially like colonic pseudo obstruction can definitely do this. And then the second class

is secondary abdominal compartment syndrome. And this is largely due to folks with systemic inflammation

who are getting lots and lots of fluid and they essentially just get like this systemic congestion.

I'm told that 10, 20 years ago, this was more common when fluid resuscitation volumes were higher.

But Josh has posted in the post about some amazing correlations between

fluid resuscitation levels and incidence of abdominal compartment pressures. So Josh, when I

crush patients with fluids, is it a linear correlation? Is it logarithmic? What kind of things do I

need to think about here? There seems to be maybe a quasi-linear

relationship with the amounts of fluid that's given and the abdominal compartment syndrome.

And of course, this is retrospective correlational data. It's not super. It's hard to say that

it's causal. It's also theoretically possible that fluid administration kind of just correlates
