Catheter Access Management for Acute Peritoneal Dialysis

Area of Science:

• Pediatric Nephrology
• Interventional Nephrology
• Renal Replacement Therapy

Background:

• Peritoneal dialysis (PD) catheter insertion is typically performed by interventional nephrologists for adults, but pediatric procedures are usually done by pediatric surgeons.
• Delayed PD initiation in children due to surgeon unavailability can increase risks of complications and chronic kidney disease.
• Vascular access, including central vein catheter (CVC) placement, is crucial for initiating renal replacement therapy in pediatric acute kidney injury.

Observation:

• A 10-kg infant with hemolytic uremic syndrome diarrhea required multiple invasive procedures for acute kidney injury management.
• Interventional nephrologists performed PD catheter insertion, PD catheter revision, CVC placement, and CVC revision in this pediatric case.
• The procedures were successfully completed by the interventional nephrology team.

Findings:

• Interventional nephrologists demonstrated capability in performing essential PD and CVC procedures in a pediatric patient.
• The team successfully managed acute kidney injury through timely and appropriate interventions.
• The patient's normal kidney function was recovered, and chronic complications were averted.

Implications:

• This case highlights the potential for interventional nephrologists to manage PD and CVC access in pediatric patients, especially when pediatric surgeons are unavailable.
• Expanding the role of interventional nephrologists in pediatric procedures could improve timely access to renal replacement therapy.
• Such interventions can lead to better patient outcomes, including recovery of kidney function and avoidance of long-term sequelae.
