Anaesthesist. 1976 May;25(5):239-45.
With the use of high voltage electric currents in patients who initally have been anaesthetised, the anaesthesiologist faces new aspects. For this reason basic principles of physical medicine and medical engineering with respect to special problems are described. The majority of impulses current generators used so far do not even comply with the first principal requirement of any therapy namely knowledge of the dose of the agent applied. A system for electric currents crossing the body is outlined, which is characterized by constant current and isovoltage-free outlets in connection with a special ECG-amplifier and a control pattern. This apparatus for the first time guarantees maximal safety in clinical use. First animal experiments demonstrate the possibility of the risk if this method is applied in a inexperienced manner: in all animals ventricular fibrillation could be achieved when the electrodes were used in a position near the heart and there appeared to occur nonspecific reactions when current was directed through the brain (ear acupuncture)
对于最初已麻醉的患者使用高压电流时，麻醉医生面临新的情况。因此，描述了物理医学和医学工程关于特殊问题的基本原理。到目前为止使用的大多数脉冲电流发生器甚至不符合任何治疗的首要主要要求，即所应用药物剂量的知识。概述了一种用于电流穿过身体的系统，其特点是恒流和无等压输出，并配有特殊的心电图放大器和控制模式。这种仪器首次保证了临床使用中的最大安全性。首次动物实验证明，如果以无经验的方式应用这种方法存在风险的可能性：当电极靠近心脏位置使用时，所有动物都能诱发心室颤动，并且当电流通过大脑（耳针）时似乎会出现非特异性反应。
