#CRRT continuous renal replacement therapy.. kinda like an artificial kidney, works 24hrs to filter gunk outta your blood. Useful when pts are extremely uremic, septic, have refractory acid base imbalance and can even dialyze some poisons. Usually patients are critically ill and hemodynamically unstable because they can't tolerate the usual intermittent dialysis (HD) or peritoneal dialysis. The idea is great! However, there aren't clear indications on when it should or shouldn't be used, and it's now expanding to non-renal indications. How do you all use it in your practice??
