目前胸外除(室)颤法需使用高电能,可损伤心肌。为降低所需电能,作者们研究了一种新方法。实验时用犬20条。硫喷妥钠麻醉下气管内插管,控制呼吸。用50～100伏特交流电引颤,室颤确定后一分钟,用标准的学相脉冲波直流电除颤。通电途经为:(1)经皮通过心尖刺入心腔的穿刺针;(2)经颈外静脉送至右心室尖部的电极导管。使用心脏穿刺针者用10—60瓦秒除颤成
At present, extrathoracic (room) tremor need to use high-energy, can damage the myocardium. To reduce the amount of energy needed, the authors studied a new method. 20 dogs experiment. Thiopental anesthesia under endotracheal intubation, control of breathing. Quivering with a 50- to 100-volt AC, defibrillation of ventricular fibrillation one minute later defibrillates with a standard learning phase pulse DC. Via the (1) percutaneous puncture through the heart of the puncture needle; (2) sent to the tip of the right ventricular catheter through the jugular vein. Use a cardiac puncture needle with 10-60 watt seconds defibrillation into
