A CLINICAL EVALUATION OF THE PERFORMANCE CHARACTERISTICS OF THREE COMMERCIALLY AVAILABLE EXTRACAPILLARY BLOOD FLOW TYPE HOLLOW FIBER MEMBRANE OXYGENATORS

Abstract

During clinical hypothermic cardiopulmonary bypass, performances of three groups of membrane oxgenators (Bard HF-5000(H), MERA EXCELLING α(M), Capiox-E (C)) have been studied in 39 patients with aortocoronary bypass operation for ischemic heart disease. (1) O₂transfer performance was more excellent in (H) than in (M) and (C). (2) Plasma free hemoglobin was higher in (C) group than (H) and (M) group. (3) Platelet count postoperatively was higher in (H) group than in (M) and (C) group. (4) Coagulation factors were not significantly different in each three group.
