作者选用6只体重31～61公斤的雌绵羊,术前用阿托品0.5mg,硫喷妥钠麻醉后,经口气管插管,保持一定容积的0.5～1.0％氟烷和氧化二氨通气,然后切断下咽缩肌,暴露右PCM,用4根直径1mm钢质圆形肌电图电极插入肌肉,并用无损伤缝线固定,其导线连接到动物颈部皮肤表面的适当位置;剖腹,又用同样的4根电极置于膈肌右份,体外导线置于右胸壁。术后第一天给动物肌注甲苯噻嗪(rompun)0.005～0.009ml/kg,镇静后对PCM
The authors selected 6 female sheep weighing 31-61 kg. Preoperative anesthesia with atropine 0.5mg, thiopental anesthesia, orotracheal intubation, to maintain a certain volume of 0.5 to 1.0% halothane and oxidized diamine ventilation, and then The hypopharyngeal muscle was cut off, the right PCM was exposed, four muscles of diameter 1 mm round steel electromyographic electrode were inserted into the muscle and fixed with a non-destructive suture, the wire of which was connected to the appropriate place on the skin surface of the animal’s neck; The same four electrodes placed in the right diaphragm, the extracorporeal wire placed in the right chest wall.
