Abstract:
Masseter muscle rigidity during general anesthesia is considered an early warning sign of a possible episode of malignant hyperthermia. The decision whether to continue or discontinue the procedure depends on the urgency of the surgery and severity of masseter muscle rigidity. Here, we describe a case of severe masseter muscle rigidity (jaw of steel) after succinylcholine (Sch) administration during general anesthetic management for rigid bronchoscopic removal of a tracheal foreign body. Anesthesia was continued uneventfully with propofol infusion while all facilities were available to detect and treat malignant hyperthermia.
