ABSTRACT
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.
