严重出血性休克即使控制失血仍因供氧需氧矛盾、心内膜下明显受损，而致心肌功能失常。近年便携式体外循环机的改进又不需肝素化，临床试用于抢救心梗或肺梗塞已有成功的报道。严重创伤病人用心肺支持（CPS）是否有盖尚无定沦。为此作者将羊制成出血休克模型，复苏时使用CPS观察对左室功能、心肌血流量以及代谢的影响。作者选择24只羊在右房和右股动脉置旁路导管。左室心尖处置放高度传真性测微压力计。左室短轴心内膜置放超声计量晶
Severe hemorrhagic shock, even though the control of blood loss is still due to oxygen aerobic contradictions, subendocardial significantly damaged, causing myocardial dysfunction. In recent years, the improvement of portable cardiopulmonary bypass without the need for heparin, clinical trials to rescue myocardial infarction or pulmonary infarction has been successfully reported. Serious traumatic patients with cardiopulmonary support (CPS) is still no fixed cover. For this reason, the author made a model of hemorrhagic shock in sheep and used CPS to observe the effect on left ventricular function, myocardial blood flow and metabolism during resuscitation. The authors selected 24 sheep to bypass the catheter in the right atrium and the right femoral artery. Left ventricular apex disposal of high degree of precision fax micrometer. Left ventricular short axis endocardial ultrasound measurement of crystal
