Continuous arteriovenous hemofiltration in premature infants.
Five critically ill premature infants with acute renal failure (ARF) and hypervolemia were treated by continuous arteriovenous hemofiltration (CAVH). Prostacyclin was used to prevent hemofilter clotting. Mean treatment duration was 53.6 +/- 14 h. Mean blood flow rates of 1.6 +/- 0.22 ml/min and filtration fractions of 17.2 +/- 3.7% produced mean ultrafiltration rates of 8.3 +/- 3.1 ml/kg.h. Fluid overload was easily corrected by means of CAVH. The mean prehemofiltration serum creatinine and urea levels were 2.3 +/- 0.4 and 77 +/- 29.7 mg/dl; the mean posthemofiltration levels were 2.38 +/- 0.43 and 92 +/- 34.4 mg/dl, respectively. Hemofilter clotting occurred every 14 h. Urinary output was restored in three infants. Three of the five infants died, but none of the deaths was related to ARF or CAVH. CAVH is a safe and simple method to control fluid and metabolic imbalances in critically ill premature infants.
