Continuous renal replacement therapy for critically ill infants and children

Area of Science:

• Pediatric Critical Care Medicine
• Nephrology
• Renal Replacement Therapy

Background:

• Continuous renal replacement therapy (CRRT) is a vital treatment for critically ill children experiencing acute kidney injury (AKI).
• CRRT has become the predominant renal replacement therapy method over the last decade.
• This study investigates outcomes for children undergoing CRRT for AKI, comparing them to adults and analyzing pediatric subgroups.

Purpose of the Study:

• To compare renal recovery (RR) and mortality rates in children and adults treated with CRRT for AKI.
• To assess the impact of weight (above vs. below 10 kg) on RR and mortality in pediatric CRRT patients.

Main Methods:

• A prospective cohort study was conducted over 13 years at a pediatric intensive care unit (PICU).
• Data collected included patient demographics, diagnosis, CRRT indications, vasoactive drug use, duration of CRRT and PICU stay, mortality, and RR.
• 36 critically ill children receiving CRRT were analyzed.

Main Results:

• The overall mortality rate among the 36 children was 39%, with sepsis and multiple organ failure being the primary diagnoses.
• 80% of patients initiated CRRT due to a combination of anuria/oliguria, severe azotemia, and fluid overload.
• Among the 22 survivors, eight experienced persistent renal impairment at PICU discharge.

Conclusions:

• CRRT is an effective intervention for hemodynamically unstable children with AKI.
• No significant difference in mortality was observed between pediatric patients weighing above or below 10 kg.
• Children treated with CRRT for AKI exhibited lower mortality compared to adults, but a smaller proportion achieved full renal recovery.
