摘　　要：目的总结45例患者心脏复苏困难的成功处理经验,寻求心脏直视术中心脏复苏困难的有效治疗方法。方法对经多次除颤不能复苏的心脏手术患者,采用重新阻断升主动脉,行4∶1半钾或全钾温血停搏液诱停加纯温血持续灌注,待心脏完全静止后再开放升主动脉的方法。结果 45例心脏手术患者心脏复苏困难经过再次停跳温血灌注的处理后均复苏成功。结论再次阻断升主动脉,行4∶1半钾或全钾温血停搏液诱停加纯温血持续灌注的处理,对于复苏困难的心脏具有较好的临床效果。[ Objective ] To summarize experiences of difficult cardiac resuscitation and explore a new method of myocardial protection. [Methods] In 45 patients with repeated failed cardiac defibrillation, the aorta was cross- clamped again, then the heart was re-perfused with 4：1 warm blood cardioplegia（hypokalemia） and pure warm blood. After the aorta was unclamped , most patients regained normal heart beat. [ Results ] The heart recovered its beat in all 45 patients. [ Conclusions ] Re-block the aorta and warm blood reperfusion is an effective method for the pa- tients with difficulty in heart resuscitation during open heart surgery.
