Monitoring of the spontaneous electromyographic activity of the frontal muscles (FEMG) is used for detection of impending arousal during general anaesthesia. Since the irritation caused by an endotracheal tube in situ might enhance the sensitivity of neck muscles in detecting arousal, EMG recordings from sternocleidomastoid muscles (NEMG) were compared to FEMG recordings under five different clinical conditions with 10 patients in each group. Two Anesthesia and Brain Activity Monitors (ABM, Datex Instrumentarium, Helsinki) were used simultaneously for recordings. NEMG was more sensitive than FEMG in detecting increases in EMG activity under all five conditions, although less distinct under conditions with a profound (90-100%) neuromuscular blockade. The results thus support our initial hypothesis and favour the use of neck muscles for monitoring. This, however, does not allow simultaneous recording of EEG through the same electrodes.
监测额肌的自发电肌电图活动（FEMG）用于检测全身麻醉期间即将发生的觉醒。由于气管内导管原位引起的刺激可能会提高颈部肌肉检测觉醒的敏感性，因此在五种不同临床条件下，对每组10例患者的胸锁乳突肌肌电图记录（NEMG）与额肌肌电图记录进行了比较。同时使用两台麻醉和脑活动监测仪（ABM，Datex Instrumentarium，赫尔辛基）进行记录。在所有五种条件下，NEMG在检测肌电图活动增加方面比FEMG更敏感，尽管在深度（90 - 100%）神经肌肉阻滞的条件下不太明显。因此，结果支持了我们最初的假设，并倾向于使用颈部肌肉进行监测。然而，这并不允许通过相同电极同时记录脑电图。
