Summary
Acute renal failure (ARF) in children treated in the pediatric intensive care unit (PICU) was reviewed. Diarrhea-associated hemolytic uremic syndrome led to ARF with excellent survival, unlike other causes with higher mortality.
Area of Science:
- Pediatric Nephrology
- Critical Care Medicine
Background:
- Acute renal failure (ARF) requiring renal replacement therapy (RRT) in a pediatric intensive care unit (PICU) presents unique challenges.
- Understanding the causes, treatments, and outcomes of ARF in critically ill children is crucial for improving patient care.
Purpose of the Study:
- To review a cohort of children with ARF who required RRT in a PICU.
- To identify the primary causes of ARF in this population.
- To evaluate the treatment modalities and renal outcomes in children with ARF.
Main Methods:
- Retrospective review of case records for children admitted to the PICU between January 1992 and July 1995.
- Data collected included demographics, diagnosis, RRT modality, treatment duration, complications, and renal outcomes.
- Long-term renal function follow-up was obtained from referring pediatricians.
Main Results:
- Twenty children (mean age 2 years 3 months) required RRT for ARF.
- Diarrhea-associated hemolytic uremic syndrome was the most common cause (mean dialysis duration 11.5 days).
- Eight patients had normal renal function at discharge; eight of ten had normalized serum creatinine on long-term follow-up. Four children with sepsis and multiorgan failure died.
Conclusions:
- Diarrhea-associated hemolytic uremic syndrome is the leading cause of ARF in PICU patients, associated with 100% survival.
- ARF from other causes in critically ill children carries a significantly higher mortality rate (27%).
