Peritoneal dialysis in very low birth weight neonates

Abstract

© 2017 International Society for Peritoneal Dialysis. ♦ Background: The aim of this retrospective study is to evaluate clinical characteristics and outcomes of very low birth weight (VLBW) neonates with acute kidney injury (AKI) treated with peritoneal dialysis (PD). ♦ Methods: This retrospective study included 10 VLBW neonates treated with PD. Intravenous (IV) cannula and umbilical venous catheter were used for the peritoneal access. ♦ Results: Mean age at the moment of starting PD was 14.9 ± 9.3 days. Mean body weight (BW) was 825 ± 215 g. The average gestational age was 26.3 ±1.1 weeks. The average duration of dialysis was 20.5 ± 14.7 h. The average ultrafiltration was 7.7 ± 4.2 mL/kg/h. At the moment of starting PD, the average BW was 302 ± 317g (22 ± 13%), higher than at birth (in patients who had PD started in first 2 weeks of their lives) or higher than the BW before AKI was diagnosed (patients who had PD started when they were older than 2 weeks). The main cause of AKI was sepsis (n = 8/10). Dialysate leak was registered in 2 patients, 1 patient had peritonitis and the other had a blocked PD catheter. Six patients died during PD (severe sepsis), 1 died due to hypoxic encephalopathy and coma, and 2 patients survived. One patient (with hypoxic encephalopathy and coma) died 10 days after PD was stopped due to sepsis. The overall mortality was 80%. ♦ Conclusion: Acute PD is still an appropriate treatment choice for VLBW neonates with AKI. In VLBW neonates, PD can be performed with an improvised PD system and catheters.
