在持续硬膜外麻醉了经尿道电切膀胱侧壁肿瘤时常出现强力的闭孔神经反射而导致膀胱穿孔。预防闭孔神经反射的常用方法是闭孔神经阻滞麻醉或改成全身麻醉，但效果均不理想。我们采用电凝刺激疲劳法以提高闭孔神经冲动的阈值，从而减轻或避免闭孔神经的反射。方法临床资料：1994 In the continuous epidural anesthesia of transurethral resection of cyst side wall tumors often appear strong obturator nerve reflex resulting in bladder perforation. Prevention of obturator nerve reflex is commonly used method of obturation or closed to general anesthesia, but the effect is not satisfactory. We use electrocoagulation to stimulate the fatigue method to increase the threshold of obturator nerve impulses, thereby reducing or avoiding obturator nerve reflex. Methods Clinical data: 1994
