[Perioperative management of a patient with systemic lupus erythematosus, myasthenia gravis, and pemphigus foliaceous]

Abstract

A 38-year-old female with systemic lupus erythematosus (SLE), myasthenia gravis (MG), and pemphigus foliaceous (PF) was scheduled to undergo total hysterectomy and lymphadenectomy. Preanesthetic examination revealed anemia, a prolonged activated partial thromboplastin time, and a reduced percent vital capacity. Antiphospholipid antibody was not positive. After treating the bullous lesions of PF and the muscle weakness due to MG (noted on admission for surgery) with oral prednisolone, the patient was scheduled for surgery. To avoid the use of a muscle relaxant and the potential complications of the airway manipulation involved in using a laryngeal mask or endotracheal tube, since the patient had MG and PF, a regional anesthetic technique was selected. This involved continuous epidural anesthesia, achieved using 1% or 2% mepivacaine, with sedation by a combination of propofol infusion (3 mg.kg-1.hr-1) and nitrous oxide (60% in oxygen). The patient breathed spontaneously under the mask throughout the 3.5-hr operation. The intraoperative surgical and anesthetic course was uneventful. After a benign postoperative course, the patient was discharged on the 16th postoperative day.
