[Peritoneal dialysis in children after cardiac surgery].

The authors analyse their experience with the use of peritoneal dialysis (PD) in children with acute renal failure after cardiac surgery. From 1995 through 1998, 1246 children were operated in Pediatric Cardiocenter 38 of them developed acute renal failure and required peritoneal dialysis. Indications for PD were oliguria, anuria, hyperkalemia and fluid overload with generalized tissue oedema. PD was instituted at mean 33.9 (3-132) hours after surgery and lasted mean 53.7 (6-264) hours. None of the patients developed peritoneal infection. Hyperglycaemia developed in 8 patients and was treated with continuous insulin infusion. 5 patients required catheter reposition or reinsertion due to inadequate fluid removal and 1 patient required another renal replacement therapy. 22 (57.9%) patients died due to intractable low cardiac output. 16 survivors recovered their renal functions. In a long-term follow-up, 7 patients had no signs of significant renal dysfunction. In 4 patients, mild elevation of N-acetyl-beta-D-glukozaminidase indicates mild proximal tubular dysfunction. These findings together with aminoaciduria in 5 patients will require a further follow-up. (Tab. 2, Fig. 1, Ref. 16.)
