Optimal Sodium Concentration for Peritoneal Dialysis in Cats

Abstract

In cats with experimentally induced acute renal failure, a silicon disk catheter was placed in the peritoneal cavity, and dialysis was made with 40 ml/kg containing 130, 140 or 155mEq/l sodium. There was no significant difference in drainage volumes, showing a mean maximum level of 12.3ml/kg at 1h-dialysis. With 130 mEq/l sodium serum sodium concentration tended to decrease, and sodium level exceeded the normal one after dialysis with 155 mEq/l sodium. With 140 mEq/l sodium, the serum sodium level remained within the normal range.
