Multicenter StudyA clinical predictive score for postoperative myasthenic crisis.
Myasthenia gravis (MG) is an autoimmune disease mostly caused by autoantibodies against acetylcholine receptor associated with thymus abnormalities. Thymectomy has been proven to be an efficacious treatment for patients with MG, but postoperative myasthenic crisis often occurs and is a major complication. We aimed to develop and validate a simple scoring system based on clinical characteristics in the preoperative status to predict the risk of postoperative myasthenic crisis. ⋯ A simple scoring system based on 3 preoperative clinical characteristics can predict the possibility of postoperative myasthenic crisis.
