There is growing use of continuous renal replacement therapy (CRRT) for pediatric patients, but no large studies reporting CRRT use and outcome in young children. We describe a cohort of patients weighing 10 kg or less who underwent CRRT at five US children's hospitals between 1993 and 2001. ⋯ CRRT is feasible and useful in children weighing 10 kg or less. Hemodynamic instability requiring pressor support neither precludes successful CRRT nor adversely affects survival. After CRRT, the survival rate in children who weigh 3 to 10 kg is similar to that in older children and adolescents.
