Abstract
The experimental study of small-sized pump-oxygenator newly designed for infant was performed. Capiox a 08R was used as a oxygenator, and PKS-KidneyR was employed as a roller pump. Mongrel dogs, weighed 4 to 5 kg, were subjected to cardiopulmonary bypass usi ng this pump oxygenator for three hours. The priming volume was 300ml, and 140ml of blood as well as 60ml of additive drugs had to be given to the lines during the cardiopulmonary bypass of 3 hours. 100ml of uncollected cardioplegic solution was included to the circulating volume. This small-sized pump-oxygenator especially designed for the cardiac surgery in neonates and small infants is sufficient for 3 hours of cardiopulmonary bypass with 300ml of priming volume, but in clinical use it is safe to add some extra volume to the prime.
