AbstractMyasthenia gravis (MG) is an autoimmune disease affecting neuromuscular junction, which is characterized by fluctuating muscle weakness and abnormal fatigability. The use of muscle relaxants is major concern in anesthetic management for patients with MG. Muscle relaxant is a practical tool to assure immobilization during surgery under general anesthesia Anesthetic management without muscle relaxants for patients with MG is challenging, because it is difficult to assure immobilization. However, pharmacological effects of muscle relaxants can be prolonged in patients with MG, resulting in the increased incidence of postoperative respiratory support. We, here, describe an anesthetic management of an 82-year-old man with MG undergoing laparoscopic surgery. Anesthesia was induced with propofol and remifentanil Desflurane was administered via a face mask, and the patient was manually ventilated for 10 min, and the trachea was intubated safely without muscle relaxants. Anesthesia was maintained with desflurane and remifentanil. We did not administer muscle relaxants to the patient during surgery. Throughout laparoscopic procedures, no movements of the patient were observed, and there were no problems concerning the laparoscopic view of the operation filed. The surgery was uneventful. The patient emerged from anesthesia smoothly, and was extubated safely. The postoperative course of the patient was also uneventful.
