Question

1. There is some indication that COVID patients may need dialysis at a higher rate than standard ICU patients. Research and explain dialysis. Also, why would it be used in the ICU?

Answer 1

Dialysis can be defined as a process whereby the solute composition of a solution is altered by exposure to another solution through a semipermeable membrane.
Dialysis disequilibrium syndrome is a rare but serious complication mostly associated with aggressive hemodialysis. Manifestations include irritability, fatigue, headache, nausea, blurred vision, muscle cramps, and tremulousness. Hypertension, elevated intraocular pressure, and asterixis are sometimes seen. The syndrome is likely to occur with recently initiated dialysis, utilization of a rapid dialysis protocol, or dialysis with ultrafiltration, especially when initial serum osmolality is high.

continuous dialysis for ICU patient provides better fluid removal.
Acute renal failure is a common complication in the intensive care unit (ICU). Over the last 25 years, there have been significant technological advances in the delivery of renal replacement therapy, particularly as it pertains to the critically ill patient population. Despite these advances, acute renal failure in critically ill patients continues to carry a poor prognosis.
Acute dialysis-dependent renal failure is a common problem in the intensive care unit (ICU) and, despite significant improvements in the care of critically ill patients, the mortality from this complication remains over 50%.
