Study Groups

Dexmedetomidine group
Dexmedetomidine supplemented morphine analgesia is provided for patients in this group in the form of patient-controlled intravenous analgesia. The formula contains a mixture of morphine (0.5 mg/ml) and dexmedetomidine (1.25 ug/ml), diluted with normal saline to a total volume of 160 ml. 5-HT3 receptor antagonist is added when necessary. The analgesic pump is set to administer a background infusion at a rate of 1 ml/h, with patient-controlled bolus of 2 ml each time and a lockout time from 6 to 8 minutes.
Dexmedetomidine supplemented morphine analgesia
Patients in this group receive patient-controlled intravenous analgesia for 3 days after surgery. The formula is a mixture of dexmedetomidine (1.25 ug/ml) and morphine (0.5 mg/ml), diluted with normal saline to 160 ml. 5-HT3 receptor antagonist is added when necessary. The analgesic pump is set to administer a background infusion at a rate of 1 ml/h, with a bolus dose of 2 ml at each time and a lockout time from 6 to 8 minutes.
Control group
Morphine analgesia is provided for patients in this group in the form of patient-controlled intravenous analgesia. The formula contains morphine (0.5 mg/ml), diluted with normal saline to a total volume of 160 ml. 5-HT3 receptor antagonist is added when necessary. The analgesic pump is set to administer a background infusion at a rate of 1 ml/h, with patient-controlled bolus of 2 ml each time and a lockout time from 6 to 8 minutes.
Morphine analgesia
