经用标准的高能量经胸除颤无效的心室颤动是一种紧急情况,以往采用开胸心肺复苏进行体内除颤,但成功率不高。最近已研制了一些改良的紧急除颤装置。本文综述1986～1992年间加州大学旧金山分部在院内各种场合中对15例经过二次及以上高能量经胸电击治疗无效的顽固性心室颤动患者,采用改良的抢救性除颤情况。 Varying ventricular fibrillation, which is ineffective with standard high-energy transthoracic defibrillation, is an emergency that was previously treated by thoracotomy cardiopulmonary resuscitation for defibrillation but with a poor success rate. Recently, some improved emergency defibrillation devices have been developed. This article reviews the case of 15 patients with refractory ventricular fibrillation who underwent secondary and high-energy thoracic shock therapy in the hospital for various occasions during the period 1986-1992 at the University of California, San Francisco Division using improved rescue defibrillation.
