Advances in Kidney Replacement Therapy in Infants

Area of Science:

• Pediatric Nephrology
• Neonatal Intensive Care
• Renal Replacement Therapy

Background:

• Acute kidney injury (AKI) is prevalent in neonatal intensive care units, affecting up to one-third of critically ill infants.
• Noninvasive treatments are first-line, but kidney replacement therapy (KRT) becomes necessary when conservative measures fail.

Purpose of the Study:

• To review current kidney replacement therapy (KRT) modalities for neonatal populations.
• To discuss the challenges, recent advances, and future directions of KRT in neonates.
• To highlight novel technologies such as the Cardio-Renal Pediatric Emergency Dialysis Machine, Newcastle infant dialysis and ultrafiltration system, and Aquadex system.

Main Methods:

• Literature review of existing studies on neonatal KRT.
• Analysis of challenges and advancements in peritoneal dialysis, hemodialysis, and continuous KRT for neonates.
• Focus on emerging technologies for neonatal ultrafiltration and dialysis.

Main Results:

• Established KRT modalities (peritoneal dialysis, hemodialysis, continuous KRT) present unique challenges in neonates.
• New technologies show promise in addressing limitations of current KRT methods for this population.
• Specific devices like the CAPE-D, NIDUS, and Aquadex system offer potential improvements.

Conclusions:

• Neonatal KRT is complex, requiring tailored approaches and innovative solutions.
• Advances in technology are crucial for improving outcomes in critically ill neonates with AKI requiring KRT.
• Further research and clinical application of new devices are warranted.
