Abstract:
Two patients with chronic renal failure on hemodialysis, received rapid transfusion of packed red blood cells (PRBCs) because of massive intraoperative bleeding. To eliminate the excessive potassium in PRBCs, a potassium adsorption filter (Kawasumi KPF-4, Kawasumi Laboratories, INC., Tokyo, Japan) was applied during surgery. The potassium adsorption filter successfully reduced the potassium concentration from 14.4-22.0 mEq x l(-1) to 1.9-3.7 mEq x l(-1). A potassium adsorption filter is a simple and useful alternative for removal of excessive potassium in PRBCs.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
