Anesthetic Management of Myotonic Dystrophy: A case report

Abstract

Myotonic dystrophy is a muscle disorder characterized by progressive muscle wasting and weakness associated with myotonia. It is a systemic disease transmitted in an autosomal dominant pattern. Myotonia may be precipitated by hypothermia, shivering, and mechanical or electrical stimulation. Furthermore, sensitivity to sedative, anesthetic and neuromusclular blocking agents may result in intraoperative and early postoperative cardiovascular and respiratory complications, as well as prolonged recovery from anesthesia. Therefore, a patient with myotonic dystrophy is at high risk for complications from anesthetic management. We report the successful anesthetic management of such a patient undergoing a total abdominal hysterectomy, in which we used an epidural technique for intraoperative anesthesia and postoperative analgesia.
