This study was undertaken to reveal the limitations and problems with the conventional mechanical circulatory assist devices by analyzing the results in 70 cases; intraaortic balloon pumping (IABP group, n = 42), venoarterial bypass pumping (VAB group, n = 18), and extracorporeal membrane oxygenation (ECMO group, n = 10). The IABP could significantly prevent the development of postoperative low cardiac output state, and the best survival rate (62 percent) was obtained in the coronary arterial disease group. In the VAB group, eight (44 percent) cases were weaned, and four (22 percent) cases survived. These conventional assist devices could, though with limitations, certainly support the circulation and/or provide a period for it to recover, otherwise bridging the patients to new methods. The early decision not only for initiation of mechanical assist devices but also for moving to more definite procedures will improve the results with such devices.
本研究旨在通过分析70例患者的结果，揭示传统机械循环辅助装置的局限性和问题；这些患者分为主动脉内球囊反搏组（IABP组，n = 42）、静脉-动脉旁路泵组（VAB组，n = 18）和体外膜肺氧合组（ECMO组，n = 10）。IABP能显著预防术后低心排血量状态的发生，冠状动脉疾病组的生存率最高（62%）。在VAB组中，8例（44%）患者成功脱机，4例（22%）存活。这些传统的辅助装置虽有局限性，但肯定能支持循环和/或为其恢复提供一段时间，从而将患者过渡到新的治疗方法。不仅要尽早决定启动机械辅助装置，还要尽早决定采用更确切的治疗方法，这将改善此类装置的治疗效果。
