OBJECTIVE: To investigate whether a single dose of @entity1339 , administered when the adductor pollicis muscle presents 2 twitches in @entity3370 ( @entity3370 ) stimulation, can reduce the @entity3370 ratio in the corrugator supercilii muscle. @entity1 AND METHODS: We designed a case-control study of @entity1 between 18 and 65 years of age classified ASA 1-2. We used 2 accelerometers--1 for the cubital nerve/thumb adductor muscle and 1 for the facial nerve/corrugator supercilii muscle. @entity4094 was induced with 0.6 mg x kg(-1) of @entity2898 , and 40 microg x kg(-1) of @entity1339 was administered at the third twitch in the @entity3370 in the thumb adductor. If the @entity3370 ratio in the corrugator supercilii fell by 10% or more at that time, the @entity1 was classified as a case. We recorded the age, sex, weight, height, body mass index, duration of the procedure, and @entity3370 ratio in the corrugator supercilii muscle when the @entity1339 was administered. RESULTS: Ten cases and 10 controls were enrolled. No significant differences between cases and controls were found in any variables except the mean (SD) @entity3370 ratio in the corrugator supercilii muscle: 70.9% (17.8%) in cases and 35.3% (7.8%) in controls (P < .001). CONCLUSIONS: In our @entity1 , administration of @entity1339 after the appearance of the third twitch in @entity3370 stimulation of the thumb adductor was associated with a reduction in the @entity3370 ratio in the corrugator supercilii. The similarity between blockades of the corrugator muscle, the diaphragm, and the larynx is of clinical interest.
