title: [Monitoring of muscle relaxation at the corrugator supercilli muscle in a patient with atrophied upper limbs].
abstract: We report a patient whose muscle relaxation was monitored at the corrugator supercilli muscle. In a 51-year-old woman with markedly atrophied upper limbs, anesthesia was induced with propofol and fentanyl. Muscle relaxation was monitored at the adductor pollicis and corrugator supercilli muscles with accelomyography. Train-of-four ratio (TOFR) could be evaluated at the corrugator supercilli muscle; however, it could not be evaluated at the adductor pollicis muscle. The trachea was intubated when the TOFR was 0.09 at the corrugator supercilli muscle after intravenous vecuronium. As the TOFR was 1.44 when the surgery completed, the trachea was extubated without giving neostigmine to antagonize the effect of vecuronium. There was no recurarization after extubation. We conclude that evaluation of TOFR at the corrugator supercilli muscle is useful in some patients who have atrophied adductor pollicis muscle.
