Advances in pediatric renal replacement therapy for acute kidney injury

Area of Science:

• Pediatric Nephrology
• Critical Care Medicine
• Renal Replacement Therapy

Background:

• The spectrum of diseases causing pediatric acute kidney injury (AKI) and requiring renal replacement therapy (RRT) has evolved.
• Historically, intrinsic renal disease and burns were primary causes; however, advancements in critical care have led to AKI from systemic diseases.
• Improvements in continuous renal replacement therapy (CRRT) technologies have influenced RRT modality choices.

Purpose of the Study:

• To review pediatric-specific etiologies for RRT provision.
• To highlight evolving practice patterns in RRT modality and treatment timing for pediatric AKI.
• To examine the application and outcomes of different RRT modalities in children with AKI.

Main Methods:

• Literature review focusing on pediatric acute kidney injury and renal replacement therapy.
• Analysis of trends in RRT modalities (peritoneal dialysis vs. CRRT).
• Examination of emerging practice patterns and outcomes in pediatric critical care nephrology.

Main Results:

• Pediatric AKI leading to RRT is increasingly associated with systemic conditions, particularly post-surgical complications in neonates and transplant recipients.
• A significant shift in RRT modality preference from peritoneal dialysis to CRRT has occurred.
• Improvements in CRRT technology have facilitated its wider adoption in critically ill children.

Conclusions:

• The causes of pediatric AKI necessitating RRT have broadened, reflecting advances in pediatric subspecialties.
• CRRT has become a preferred modality for critically ill children with AKI due to technological advancements.
• Understanding these shifts is crucial for optimizing RRT strategies and outcomes in pediatric critical care.
