Abstract
Clinical study of extracapillary blood flow type “Sarns” hollow fiber membrane oxygenator, and campard with Capiox II Sarns 16310 membrane oxygenator (group-C) which was extracapillary blood flow and low priming volume type used for open heart surgery in 22 adult patients, and was compared with intracapillary blood flow type Capiox II 43 (group-C) in 14 patients. The following vesults were obtained. The priming volume of group-S was remarkably decreased (P<0.05) than that of group-C. The amount of bank blood for group-S tended to be less than that for group-C. When the Sarns oxygenator is used, the cases with clear water priming for ECC in creases. In group-S O2 transfer was better than that in group C and both PaO2 and PaCO2 were easily changed only by O2 flow control. In group-S showed the bubble in oxygenator removed better than the other. It yield fewer micro-bubble during ECC and was easily operated. This study indicates that the Sarns oxygenator is suitable for clinical application.
