[Open-heart surgery without donor-blood transfusion--a clinical study].
Since October 1987, 80 patients underwent open-heart surgery without donor-blood transfusion. 50 (Group I) out of these 80 cases were selected to be paired with 50 patients (Group II) who underwent open-heart surgery with homologous blood transfusion in the same period. Twelve cases (Group III) underwent open-heart surgery without homologous blood transfusion but were transfused after surgery. To decrease the homologous blood requirements, ultra-filtration system as well as conservation and autotransfusion of autologous blood was employed. Peripheral blood count, blood chemistry for liver and renal function were analyzed and compared among these three groups. Although hematocrit of Group I was lower than that of Group II until the third postoperative day, there was no difference after the seventh postoperative day. The platelet count was more in Group I than in Group II or III on the first and the seventh postoperative day. The level of lactate dehydrogenase was higher in Group II than in Group I. Total bilirubin was more elevated in Group II than in Group I on the first and the fourteenth postoperative day. Direct bilirubin was also higher in Group II than in Group I till fourteenth postoperative day. Five cases in Group II fulfilled the criteria of the serum hepatitis. Blood urea nitrogen and creatinine were less in Group I than in Group II. The duration of the intra-tracheal intubation was shorter in Group I than in Group II or III. There was no difference in postoperative dosage or duration of catecholamines among three groups.(ABSTRACT TRUNCATED AT 250 WORDS)
