Sixteen patients who had undergone open heart surgery were studied in order to determine the factors influencing cardiac performance in the postoperative period. Hemodynamic influences during and following cardiopulmonary bypass were found to be more important than the preoperative cardiac function. The flow rate used during cardiopulmonary bypass had a pronounced influence on the post-operative cardiac performance. A low flow can result in the development of vasoconstriction postoperative with an increased chance of low cardiac output. A high flow during bypass is recommended, and in the postoperative period vasoconstriction must be treated vigorously to forecome low cardiac output.
为了确定影响术后心脏功能的因素，对16例接受心脏直视手术的患者进行了研究。发现体外循环期间及之后的血流动力学影响比术前心脏功能更为重要。体外循环期间使用的流速对术后心脏功能有显著影响。低流速可导致术后血管收缩，增加低心输出量的几率。建议在体外循环期间采用高流速，并且在术后必须积极治疗血管收缩以克服低心输出量。
