Hemofiltration is accepted management for acute renal failure in critically ill patients. However, in infants, obtaining arterial access or adequate flow through the access is often difficult. We report our technique and experience with pump-assisted hemofiltration (PAHF) in ten infants with acute renal failure. In five patients, double-lumen venous catheters provided access, while two catheters at separate sites were used in the remaining patients. In all patients, hemofilters were used with standard intravenous tubing added to pre-filter tubing and placed through a standard volumetric infusion pump for regulation of blood flow. The infants, aged 5-575 days, weighed from 2.8 to 11.4 kg and had primary diagnoses of post-operative congenital heart disease in five, sepsis in four, and renal dysplasia in one. The duration of PAHF averaged 158 +/- 115 h (range 20-332 h). Complications included bleeding at a catheter or surgical site in one patient each and asymptomatic hyponatremia in five patients. Thus, with adequate nurse training, PAHF using a volumetric infusion pump for blood regulation can be acceptable therapy in acute renal failure in infants.
