Continuous arteriovenous hemofiltration: an alternative dialysis therapy in neonates

Modifications have made it possible to perform CAVH in the neonate. One of these is decreasing the extravascular volume in the tubing and filter to a minimal amount to allow for adequate intravascular blood volume in the infant. Another is utilizing predilutional fluid to decrease the need for heparinization. A third modification is utilizing the suction-assist pumps to help control the amount of fluid removed from the infant. With modifications of this system to fit the special needs of neonates and intensive nursing and medical management, CAVH can be a successful alternative to traditional dialysis therapies in neonates.
