Intraoperative Neurophysiological Monitoring and Neuromuscular Anesthesia Depth Monitoring

Abstract

Deep blocking of consciousness alone does not prevent a reaction to severe stimuli, and copious amounts of pain medication do not guarantee unconsciousness. Therefore, anesthesia must satisfy both: the loss of consciousness as well as muscle relaxation. Muscle relaxants improve the intra-bronchial intubation, surgical field of vision, and operating conditions, while simultaneously reducing the dose of inhalation or intravenous anesthesia. Muscle relaxants are also very important for breathing management during controlled mechanical ventilation during surgery. Excessive dosage of such muscle relaxants may therefore affect neurological examinations during surgery, but an insufficient dosage will result in movement of the patient during the procedure. Hence, muscle relaxation anesthesia depth and neurophysiological monitoring during surgery are closely related. Using excessive muscle relaxants is disadvantageous, since neurophysiological examinations during surgery could be hindered, and eliminating the effects of complete muscle relaxation after surgery is challenging. In the operation of neurophysiological monitoring during the operation, the anesthe-siologist administers muscle relaxant based on what standard, it is hoped that the examination will be performed more smoothly by examining the trends in the world as well as domestic and global trends in maintaining muscle relaxant.
