Challenges in Anesthetic Management of Succinylcholine-induced Masseter Muscle Rigidity in Difficult Airway Patient: A Case Report

ABSTRACT

The difficult airway is already a challenging situation for anesthesiologists, in that scenario Succinylcholine (SCh) use, because of its rapid onset and short duration of action makes it a neuromuscular blockage drug of choice. Development of masseter muscular rigidity is thought to be an early indicator of the occurrence of the dreaded consequence, malignant hyperthermia. Consequently, it is essential to understand the potential side effects of this widely used drug in order to successfully treat the airway. Resulting is the use of videolaryngoscopic intubation along with propofol use and the procedure was completed successfully with no intraoperative or postoperative problems. Here, we described a case report of a 33-year-old male patient with a difficult airway posted for open reduction internal fixation of bilateral Lefort’s III fracture, developed masseter muscle rigidity (MMR) following administration of a standard dose of SCh.
