Objectives: This study aimed to investigate the underlying causes and outcomes of less than 1500 g birth weight infants who underwent acute peritoneal dialysis (PD). Methods: Case records of infants with birthweight less than 1500 g from January 2015 to June 2018 were reviewed. Results: The median (range) birth weight and gestational age of the patients were 720 g (555–1055) and 26 weeks (23–27.5), respectively. Underlying factors for the development of acute kidney injury (AKI) were patent ductus arteriosus (PDA) (15 patients), necrotizing enterocolitis (NEC) (10 patients), sepsis (7 patients), asphyxia (2 patients) and hydrops fetalis (2 patients). Multifunctional 10 F flexible catheter was used for the procedure. Median PD onset time was 7 days (4.5–13.5) and median PD duration was 3 days (1.5–3.5). Overall mortality rate was 81 % (n=17). Conclusions: Despite high overall mortality, PD is technically feasible in very low birthweight (VLBW) and extremely low birthweight (ELBW) neonates using a multifunctional catheter.

目的：本研究旨在调查出生体重不足1500 g的急性腹膜透析（PD）婴儿的根本原因和结果。方法：回顾了2015年1月至2018年6月出生体重小于1500 g的婴儿的病例记录。结果：患者的中位（范围）出生体重和胎龄分别为720 g（555-1055）和26周（23-27.5）。发生急性肾损伤（AKI）的潜在因素是动脉导管未闭（PDA）（15例），坏死性小肠结肠炎（NEC）（10例），败血症（7例），窒息（2例）和胎儿积水（2例）耐心）。多功能10 F挠性导管用于该程序。PD发作中位时间为7天（4.5-13.5），PD持续时间中位数为3天（1.5-3.5）。总死亡率为81％（n = 17）。结论：尽管总体死亡率较高，但PD在使用多功能导管的极低出生体重（VLBW）和极低出生体重（ELBW）新生儿中在技术上是可行的。
