In this study we quantitatively evaluated, by a stable paralysis/stableinfusion rate method, the difference between two standardizedparalysis levels—train-of-four count of 2 responsesand posttetanic count of 2. Ten ASA physical status I–IIconsenting adult patients scheduled for elective surgery wereanesthetized (sufentanil/propofol), tracheally intubated, mechanicallynormoventilated with a fixed O2/air mixture, and normothermic;oropharynx and thenar temperatures were maintained above 36°and 32.5°C, respectively.
