Continuous peritoneal dialysis in newborns.

Objectives: To report the complications and outcome of 10 newborns affected by acute renal failure (ARF), treated by continuous peritoneal dialysis (CPD).

Design: All newborns admitted for tertiary treatment to the Neonatal Intensive Care Unit of the University of Padova, who underwent CPD between February 1986 and December 1990, were analyzed retrospectively.

Patients: Ten newborns (mean weight 2077 g, range 540-4930 g) received CPD, 6 of whom were preterm. All the survivors completed the study.

Interventions: A number 9, 5 French Tenckhoff catheter was used, and a closed circuit was created by means of a modified continuous ambulatory peritoneal dialysis (CAPD) technique. The mean duration of dialytic therapy was 7 days.

Results: At the end of the dialytic period, 7 of the 10 patients had normal serum potassium and sodium values. CPD produced two different types of complications: leakage of the dialytic fluid in very low weight newborns and one episode of peritonitis during a chronic dialysis treatment. Six died of severe respiratory failure (in no case, however, was this attributable to ARF or CPD procedure). All but one of the survivors regained normal renal function. The only exception necessitated a kidney transplant.

Conclusion: We believe that this technique, although invasive, improves the outcome of both preterm and low birth weight newborns affected by ARF.
