Abstract

Background: The efficacy of the hemostasis of prophylactic aprotinin after cardiac valve replacement was evaluated from January 1994 to December 1996 at Pusan National University Hospital. Material and Method: In a randomized study, 20 patients received aprotinin(2${\times}$106 KIU as a loading dose for 30 minutes after anesthesia, 1${\times}$106 KIU for priming and 5${\times}$105 KIU/hr as a maintenance dose from the completion of loading dose till skin closure) and another 20 untreated patients served as controls. Result: Aprotinin produced a significant reduction in postoperative blood loss compared with controls and significantly decreased total exposure to allogenic blood products compared with the control group(p<0.05). Conclusion: We conclude that aprotinin effectively reduces postoperative blood loss and trasfusion in patient undergoing cardiac valve replacement.

배경: 1994년 1월부터 1996년 12월까지 부산대학교병원 흉부외과에서 인공판막 치환술을 받은 40명의 환자를 대상으로 aprotinin 투여군 20명과 투여하지않은 대조군 20명으로 나누어 비교 분석하였다. 대상 및 방법: Aprotinin 투여군은 수술시작 30분이내에 200만 KIU를 정주하고 충전액에 100만 KIU를 첨가하였고 유지용량으로 수술하는 동안 시간당 50만 KIU를 투여하였다. 술전과 술후 혈색소치, 혈소판치, prothrombin time을 측정하였고 출혈량은 술후 6시간, 24시간 술후 총량을 측정하였다. 결과: 출혈량은 Aprotinin 투여군에서 대조군보다 통계학적으로 유의하게 적었고 수혈량도 Aprotinin 투여군에서 대조군보다 적었다. 결론: 저자는 aprotinin의 사용이 개심술시 출혈량과 수혈요구량을 현저히 줄이고 술후 지혈에도 도움을 준다고 생각된다.
