title: [Masseter muscle rigidity after suxamethonium during induction and postoperative abortive malignant hyperthermia in a patient with esophageal achalasia].
abstract: A 38-year-old man diagnosed as esophageal achalasia developed masseter muscle rigidity after intravenous suxamethonium during anesthetic induction. Anesthesia was maintained with intravenous agents and epidural blockade, while the masseter muscle rigidity continued. After the surgery, his body temperature increased to 38.8 degrees C concomitantly with the appearance of myoglobinuria suggesting the occurrence of abortive malignant hyperthermia. These symptoms were dissolved by dantrolene administration. He was later proved to be negative with CICR test.
