Application of repeated myocardial perfusion on difficult cardiac resuscitation under open heart operation / 中国医师进修杂志

ABSTRACT

Objective To investigate the application of repeated myocardial perfusion on difficult cardiac resuscitation after aortic unclamping under open heart operation. Methods Fifteen cases met difficult cardiac resuscitation after release of aortic cross-clamping under open heart operation were analyzed retrospectively. They were perfused with or without repeated aortic clamping, with warm blood cardioplegic solution until electric activity of cardiac muscle stop. Results All cases got cardiac resuscitation and detached from-cardiopulmonary bypass (CPB) successfully,9 cases perfused with warm blood cardioplegic solution without repeated aortic clamping got cardiac resuscitation automatically(7 cases) or after defibrillation for one time (2 cases),5 cases experiencing repeated aortic clamping and perfused with warm blood cardioplegic solution for two times got cardiac resuscitation automatically (3 cases) or after defibrillation for one time (2 cases) and another one experiencing for four times. Conclusion Application of repeated perfusion on difficult cardiac resuscitation after aortic unclamping under open heart operation is effective.
