Experimental: group 1
administration of remifentanil with target-controlled infusion (TCI) system at a given concentration during anesthetic emergence
Drug: Administration of remifentanil with TCI system
A given effect site concentration of remifentanil would be administered to subjects using TCI system. According to biased coin design, the given concentration of remifentanil is determined according to success or failure of just previously enrolled patient. If the former patient did not cough during anesthetic emergence at a given concentration (success), the next patient will be randomly allocated into the same concentration of remifentanil with 18/19 of probability or the lower concentration of remifentanil by 0.4 ng/ml with 1/19 of probability. If the former patient coughed during anesthetic emergence (failure), the next will be automatically allocated into the higher concentration of remifentanil by 0.4 ng/ml.
- The occurrence of cough during anesthetic emergence [ Time Frame: 5 min after extubation ]At a given effect-site concentration of remifentanil, if cough does not occur during anesthetic emergence, it would be considered as a success. On the other hand, if cough occurs during anesthetic emergence, it would be considered as a failure.
