Prospected Randomized Study of Two Y Devices in Continuous Ambulatory Peritoneal Dialysis (CAPD)

Abstract

To evaluate acceptability, safety, and efficacy of a y set with two short branches (TAs) filled with electrolytic chloroxidizer solution during the dwell time, 60 patients were randomly allocated to be treated with the traditional y set (TCs) or with the T AS. Twenty-three were new patients whereas the remaining 37 were patients already on continuous ambulatory peritoneal dialysis (CAPD) with the TCs. The follow-up was 416.5 months in the control group and 387.4 months in the test group. During the study period there were 6 peritonitis episodes in each group with an incidence of 1 episode every 69.4 patient-months in the control group and 1 episode every 64.6 patient-months in the test group. Twenty-four patients (80%) in the control group and 27 (90%) in the test group were free from peritonitis. The probability to remain free from peritonitis was respectively 87% and 83% in the test group and in control group after 12 months, 70% and 78% after 21 months. seventy -nine percent of the patients who used both systems preferred the T AS for better handling, lower encumbrance, and major safety. One patient preferred the TCs, three patients did not find any differences between the two devices.
