Peritoneal dialysis in the pediatric intensive care unit setting

Area of Science:

• Pediatric Nephrology
• Critical Care Medicine
• Renal Replacement Therapy

Background:

• Acute kidney injury (AKI) is a frequent complication in pediatric and neonatal intensive care units (ICUs).
• Renal replacement therapy (RRT) is crucial for managing metabolic demands and nutrition in pediatric patients with oliguric kidney failure.
• Timely initiation of dialysis is linked to improved survival rates in infants following ischemic insults.

Purpose of the Study:

• To review the current trends and considerations for choosing dialysis modalities in critically ill children with AKI.
• To compare the use and advantages of continuous RRT (CRRT) and peritoneal dialysis (PD) in pediatric ICUs.
• To highlight the factors influencing the selection of RRT modality in pediatric AKI.

Main Methods:

• Review of current literature on RRT modalities in pediatric intensive care.
• Analysis of trends in the utilization of CRRT, PD, and intermittent hemodialysis in pediatric ICUs.
• Discussion of the advantages and limitations of different RRT modalities based on patient age and clinical status.

Main Results:

• The use of CRRT in pediatric ICUs has significantly increased, while PD and intermittent hemodialysis have declined.
• Patient age is a key factor in selecting dialysis modality; PD remains common in children under 6 years.
• PD offers advantages such as lower cost, technical simplicity, and suitability for hemodynamically unstable patients.

Conclusions:

• While CRRT is preferred for acutely ill children, PD is a viable and cost-effective option, particularly for younger patients.
• Evidence suggests PD can provide adequate solute clearance in infants with AKI.
• The choice of dialysis modality should be individualized based on local expertise, available resources, and the patient's specific clinical condition.
