Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: DEX group
The DEX group will receives dexmedetomidine intraoperative.
|
Ten minutes after anesthesia induction and endotracheal intubation, patients assigned to dexmedetomidine group were given a loading dose of dexmedetomidine 0.6 μg/kg over 10 minutes, followed by continuous infusion at a rate of 0.4 μg/kg/h until the start of dural closure.
|
Placebo Comparator: Placebo group
The placebo group will receives 0.9% saline intraoperative.
|
0.9% saline is administered with the same volume at the same speed as the other group.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
The incidence of postoperative delirium
Time Frame: postoperative 5 day
|
Postoperative delirium is assessed by the combination of the Richmond Anxiety Scale (RASS) and the Confusion assessment method for intensive care unit (CAM-ICU) or the 3-minute diagnostic interview for CAM (3D-CAM) as applicable. Delirium consists of four main characteristics: acute onset of a change in mental status or a fluctuating level of consciousness, inattention, disorganized thinking and an altered level of consciousness. The patient was diagnosed as delirious if both the first and second features were present, and either the third or fourth was present. In the ICU, the delirium assessment was performed in two steps. The arousal level was first assessed by RASS. If the patient was not responsive to verbal stimuli (i.e. RASS score ≤-4), the remaining delirium assessment was aborted, and the patient was recorded as comatose. When the RASS score was greater than or equal to 3, delirium was evaluated using the CAM-ICU. Patients in general ward were evaluated by 3D-CAM. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain score
Time Frame: within 5 days after surgery
|
Numerical Rating Scales, ranging from 0 to 10 points, with 10 representing the worst imaginable pain.
|
within 5 days after surgery
|
Sleep quality
Time Frame: within 3 days after surgery
|
Quality of sleep was assessed by the Richards Campbell sleep questionnaire (RCSQ) and with a 0-100-mm visual analog scale, with higher scores indicating better sleep quality.
|
within 3 days after surgery
|
Quality of recovery from surgery
Time Frame: 1 day after surgery
|
Postoperative quality of recovery was assessed through the Quality of Recovery 15 item
|
1 day after surgery
|
Intraoperative cardiovascular event.
Time Frame: From the study drug infusion to the end of surgery.
|
Including: hypotension was defined as systolic blood pressure <95 mm Hg or less than 30% below baseline; hypertension was defined as systolic blood pressure > 180 mm Hg or more than 30% above baseline; bradycardia was defined by heart rate <40 bpm, and tachycardia was defined by heart rate >100 bpm.
|
From the study drug infusion to the end of surgery.
