Primary Outcome Measures
NameTimeMethod
Plasma concentrations of sufentanil and hydromorphone48 hours

28 blood samples are taken during the study period of 48 hours postoperatively for characterizing the pharmacokinetics

Numerical Rating Scale for Clinical Pain8 hours

11 assessments of patient's pain sensation using Numerical Rating Scale for Clinical Pain during patient-controlled analgesia with target-controlled infusion of hydromorphone 8 hours after extubation for characterizing the analgesic effect

Secondary Outcome Measures
NameTimeMethod
Total amount of hydromorphone8 hours

Cumulative dose of hydromorphone for patient-controlled analgesia with target-controlled infusion of hydromorphone for characterizing the analgesic requirement

Modified Observer's Assessment of Alertness/Sedation (MOAA/S) Scale8 hours

11 assessments of the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) Scale during patient-controlled analgesia with target-controlled infusion of hydromorphone 8 hours after extubation for characterizing the sedation level
