Abstract

Between May, 1994 and December, 1995, 122 adult cardiac surgical procedures requiring cardiopulmonary bypa s were performed at Kang Dong Sacred Heart Hospital, including 18 cases(14.8%) that were associated with preoperative(n:9), intraoperative(n=7), postoperative(n:2) use of an IABP (intra-aortic balloon pump). The reasons for IABP were low cardiac output and PTCA(percutaneous transluminal coronary angioplasty) failure in preoperative period, CPB(cardiopulmonary bypass) weaning difficulty in intraoperative period, and intractable arrhythmia in postoperative period. The mean age of the IABP patients was 61.8 $\pm$ 6.9 years(range, 39 to 75years). The overall hospital mortalities in patients with preoperative and intraoperative IABP insertion were 3 and 42.9% respectively. Two patients with postoperative IABP insertion are alive. The rate of IABP weaning is 66.7% for preoperative group, 85.7% for intraoperative group and 100% for postoperative group . In conclusion, if there were no irreversible myocardial damages, IABP could be used safely and emergently at any perioperative period for hemo ynamic stability, CPB weaning, and to overcome low cardiac output syndrome.

1994년 5월부터 1995년 12월까지 성인에서 심장수술을 시행한 122례중 18례(14.8%)에서 IABP를 순환보조장치로 사용하였다. 그중 술전에 IABP(intra-aortic balloon pump)를 시행한 경우는 9례이고, 술 중에는 7례, 그리고 술후에는 2례에서 시행하였다. 그 이유는 술전에는 저심박출, PTCA(percutaneous transluminal coronary angioplasty)의 실패였고, 술중에는 체외순환기 이탈을 위해서이며, 술후에는 술후 발생한 부정 맥 때문이었다. 환자들의 평균 나이는 61.8$\pm$6.9세(39세에서 75세)였다. 술전 및 술중에 IABP를 시행한 환자의 수술사망율은 각각 33.3, 42.9%였으며 술후 IABP를 시행한 환자는 모두 생존하였다. IABP이탈율은 술전의 경우 66.77%. 술중의 경우 85.7%였으며 술후에 시행한 IABP는 모두 이탈 가능하였다. 결론적으로 IABP는 심근 손상이 가역적인 시기에 적용할 경우, 수술전후 어느시기에나 안전하게 사용가능하며 수술전후의 혈류역학적 불안정, 체외순환기 이탈 및 저심박출증의 치료에 도움을 줄 수 있다고 판단된다.
