[Continuous arteriovenous hemofiltration in childhood. Indications and technics]
Summary
Continuous Arteriovenous Hemofiltration (CAVH) effectively treats critically ill children with acute renal failure and fluid overload. This extracorporeal therapy removes fluid and solutes without a blood pump, showing good tolerance and managing various critical conditions.
Area of Science:
- Pediatric Nephrology
- Critical Care Medicine
- Extracorporeal Therapies
Context:
- Critically ill children often experience acute renal failure, fluid overload, and electrolyte imbalances.
- Existing treatments may be insufficient for managing complex fluid and solute derangements in pediatric critical care.
- Continuous Arteriovenous Hemofiltration (CAVH) offers an alternative extracorporeal modality.
Purpose:
- To evaluate the efficacy and safety of CAVH in critically ill children.
- To assess CAVH's ability to manage acute renal failure, hypervolemia, and metabolic crises.
- To determine the tolerance and complications associated with CAVH in this patient population.
Summary:
- CAVH was used in 18 critically ill children (mean age 5.1 years) for conditions including acute renal failure, hypervolemia, and metabolic disorders.
- Various hemofilter systems were employed, with mean treatment durations of 132 hours.
- Ultrafiltration rates varied by filter system, with enhanced rates achieved using negative pressure.
Impact:
- CAVH effectively compensated for azotemia and corrected severe hypervolemia and electrolyte disorders in critically ill children.
- The therapy was well-tolerated, with the primary complication being a femoral artery thrombosis requiring surgical revision.
- CAVH demonstrated significant benefits in managing life-threatening conditions in pediatric critical care settings.
