Peritoneal dialysis using a recycling system in dogs.

Abstract

In this study, Recirculation Peritoneal Dialysis (RPD) apparatus using a pump to circulate the dialysate was devised and its dialysis efficiency was investigated. In the experiment, 15 mongrel dogs with body weights of 6.6 +/- 0.7 kg were used. The surgery to induce azotemia was performed on the dogs, a disk catheter for drainage was placed between the liver and diaphragm, and a straight catheter for infusion was placed on the abdominal side of the bladder. RPD was conducted using 2 l of dialysate containing 1.3% glucose, and the dialysate was circulated by a pump through the peritoneal cavity and the dialysate chamber at the circulation rates of 30, 60, 90 and 120 ml/min. RPD was conducted for 3 hr and the clearances of urea nitrogen, creatinine, inorganic phosphorus and potassium were recorded every hour. The clearances in RPD became higher with an increase in the circulation rate. Although RPD requires two catheters in the peritoneal cavity, it has no appreciable technical difficulty in handling and is considered to be easier than hemodialysis. RPD enabled higher dialysis efficiency to be achieved in a short time compared with conventional peritoneal dialysis. It seems reasonable to conclude that RPD is a useful new dialysis technique for animals.
