Outline of Final Research Achievements |
Mal-perfusion in contemporary pediatric cardio-pulmonary bypass (CPB) system has been occasionally found. We focused on alkalization of the priming solution induced by usual priming procedures which may lead to unexpected haemagglutination. By using recirculating circuit with a membrane oxygenator, hydrogen power (pH) of the various priming solutions, which were Lactate Ringer, Acetate Ringer, Bicarbonate Ringer, Hemodyalisate, and the various oxygenators, which were CX-FX05RW, HPO-06H-C, JK-JMOXIAIC06, D100-50534, ME62050061, BIOCUBEC2000, were studied. The results concluded that any combinations of the solutions and equipment may lead to excessive alkalization of the priming solution which may be one of the factors of mal-perfusion. In particular, gas insufflation during priming accelerates and increases the risks. Reconsideration of the priming procedures for pediatric CPB is highly recommended.
