Pediatric Emergent Peritoneal Dialysis in Intensive Care Units: Indications, Techniques, and Outcomes

Abstract

<b><i>Introduction:</i></b> This study aimed to identify risk factors affecting outcomes in pediatric patients requiring emergent peritoneal dialysis (PD) for all causes, focusing on survival rates, kidney function recovery, PD duration, complications, and quality of life. <b><i>Methods:</i></b> A retrospective review was conducted on medical records of pediatric patients who received emergent bedside PD in the intensive care unit from January 2010 to February 2023. Thirty-four catheters were placed, with demographic, preoperative, and procedural data collected. MedCalc^® Statistical Software was used for analysis with a significance level set at <i>p</i> &lt; 0.05. Prophylactic antibiotics were administered prior to surgery, and catheters were placed using a consistent technique by a single team of pediatric surgeons. <b><i>Results:</i></b> The median age at catheter placement was 39 days (range 2–2,286), and the median body weight was 3.53 kg (range 1.2–48.8). The majority were male (64.7%), with 17.6% preterm. The most common indication for PD was acute kidney injury (AKI) (88.2%), followed by hyperammonemia, metabolic acidosis, and abdominal compartment syndrome. The median waiting period for PD placement was 1 day, and the median duration of PD was 7 days. Complications included dialysate leakage (22.8%) and catheter obstruction leading to PD discontinuation (31.4%). The mortality rate was high at 71.4%. <b><i>Conclusion:</i></b> It is advisable to advocate for the early initiation of PD in pediatric patients following cardiac surgery. AKI is a significant risk factor for mortality, while prematurity increases the risk of dialysate leakage. Omentectomy and the method of catheter exit did not significantly affect outcomes. The study’s limitations highlight the need for larger prospective studies to better understand and improve emergent PD management in this vulnerable population.
