Fujimoto M, et al. - This study was designed to determine the adequate rocuronium dose required for complete block of the thigh adductor muscles, and its correlation with individual responses of the adductor pollicis muscle to rocuronium. Findings revealed that for determining the adequate rocuronium dose required for complete block of the thigh muscles, the response of the adductor pollicis muscle to rocuronium could not be used but in order to prevent the obturator jerk, intense blockade, with maintenance of post-tetanic count at ≤ 1 in the adductor pollicis muscle was considered crucial.
