Prompt left ventricular assistance by the centrifugal pump enables the survival of many patients with postoperative low cardiac output who cannot be weaned from cardiopulmonary bypass with the aid of balloon counterpulsation and inotropic agents. Successful weaning from the centrifugal pump, however, depends on the careful selection of appropriate candidates as well as the strict control of pump flow, oncotic pressure, coagulopathy, blood pressure, and systemic afterload. The installation of a hemoconcentration device into the pump line helps control hemodilution and maintain adequate oncotic pressure. The management of a patient who was totally dependent upon left ventricular assistance is described.
离心泵进行的适时左心室辅助可使许多术后心输出量低且无法借助球囊反搏和强心剂脱离体外循环的患者存活下来。然而，成功脱离离心泵取决于对合适候选者的精心挑选以及对泵流量、胶体渗透压、凝血病、血压和体循环后负荷的严格控制。在泵管路上安装血液浓缩装置有助于控制血液稀释并维持足够的胶体渗透压。本文描述了一名完全依赖左心室辅助的患者的管理情况。
