Survey on the practice of extrarenal hemofiltration in pediatrics

BACKGROUND: Several methods of dialysis are currently available. The choice of whether to use one of them is determined by multiple factors that are analyzed in this study. PATIENTS AND METHODS: One hundred and twenty-six children (mean age: 48 +/- 6 months) were treated in 29 French intensive care units and/or departments of nephrology during 1991. The underlying diseases were: hemolytic-uremic syndrome (HUS) in 28% of patients, other renal diseases in 6%, metabolic diseases in 8%, septic shock in 8%, cardiogenic shock in 9%, hypovolemic shock in 10%, multiple organ failure in 7%, acute liver disease in 9% and other diseases in 15%. RESULTS: Peritoneal dialysis (PD) was the favorite method in patients less than 10 years: intermittent hemodialysis (IHD), continuous hemofiltration and hemodiafiltration, (HF, HDF) were preferentially used above this age. PD was used in 85% of HUS, 58% of shocks and 50% of metabolic diseases. Sixty percent of acute renal diseases other than HUS were treated by IHD. HF and HDF were used in 66% of acute liver diseases and 42% of shocks. Overall mortality was 40% but no death could be directly ascribed to the different methods of dialysis. CONCLUSION: The choice of method depends on the type of underlying disease, age of the patient but also the equipment of centers. Progress in evaluating indications and results of the different methods of dialysis are necessary.
