Clinical Profile, Outcomes, and Complications in Neonates Undergoing Peritoneal Dialysis in a Tertiary Neonatal Care Unit – An Observational Study

Abstract

Peritoneal dialysis (PD) is the most common form of renal replacement therapy in neonates and there is a lot of heterogeneity in patient selection and outcomes across the various units. This study aimed to assess the indications, complications, and outcomes in terms of survival of PD. This is a retrospective study of 23 neonates who underwent acute PD at a tertiary care neonatal unit between August 2016 and July 2021. A cross-sectional poll was also conducted among the doctors who have been in the unit for the past 10 years regarding their experience in PD. The baseline, clinical, biochemical parameters, outcomes, and complications were analyzed. All statistical analyses were performed using the IBM SPSS Statistics version 23.0 software. The mean (±standard deviation) gestational age and birth weights of neonates were 32.6 ± 4 weeks and 1743 ± 922 g, respectively. Six (26%) babies had extremely low birth weight, five (22%) very low birth weight (VLBW), and seven (30%) low birth weight. The indications were acute kidney injury [17/23 (74%)], fluid overload [3/23 (17%)], suspected inborn errors of metabolism [2/23 (9%)] and hypernatremia [1/23 (4%)]. A pigtail catheter (74%) was used in most of them. Catheter block was noticed in four babies and peritonitis in two neonates. We did not encounter any complications during the procedure, and PD appears to be practicable across all gestational ages and birth weights.
