AbstractWe report anesthetic experience of two patients suffering from polymyositis. The first case is a 56 year old woman who underwent tympanoplasty for cholesteatoma of the middle ear. Anesthesia was induced with thiopental and deepened with oxygen-nitrous oxide and sevoflurane. No muscle relaxant was used for endotracheal intubation and for maintaining anesthesia. Another is a 61 year old man who underwent open reduction and internal fixation for condyle fracture of the tibia. Epidural catheter was inserted at L 3-L 4. Epidural blockade was established with 2% mepivacaine, and sedation was achieved by intravenous midazolam. Concerning the anesthetic management of a patient with polymyositis, there are some informations on the appropriate use of muscle relaxants. It is generally believed that the patient is sensitive to nondepolarizing muscle relaxants and the use of antagonist drug (reversal) may cause muscle weakness, severe dysrhythmia, et al. Therefore we think it is appropriate to manage such a patient without muscle relaxants.
