Abstract
We have already described (Lancet 1983, ii, 642) the results of a controlled study in two centres showing the efficacy of a Y-shaped connector, filled with sodium hypochlorite during the dwelling time, for the reduction of peritonitis: one episode every 33 patient-months in the treated group versus one episode every 11.3 patient-months in the control group using the standard method.
During the past 2.5 years we have continued to use the Y-connector. All new patients referred to our hospital for initiation of CAPD program were trained to use the Y-connector, while those patients already on the standard Y-connector continued on it.
From January 1983 to June 1985, among 18 non-diabetic patients using the standard bag-exchange method, there were 23 peritonitis episodes in 14 patients (78%) over a cumulative period of 257 months -one episode every 11.2 patient-months. In contrast, among the 92 patients using the Y-connector, there were 30 peritonitis episodes in 21 patients (22.8%) during 1354 months -one episode every 45.1 patient-months. When we exclude from this group the 10 diabetic patients adding insulin to the bags, the incidence of peritonitis fell to one episode every 92.2 patientmonths.
These results confirm that the Y-connector is extremely effective in reducing the rate of peritonitis in patients on CAPD.
The most widely accepted technique for prevention of peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) is that described by Oreopoulos et al (I). However, to reduce further the risk of dialysis-fluid
