Detailed Description
Shivering is a common complication in the postoperative period. The incidence of shivering has been reported to range from 5% to 65% under general anesthesia and as 33% during epidural anesthesia. Shivering can increase perioperative risk in patients. Both dexmedetomidine and meperidine are effective agents for the prevention of postanesthetic shivering. However, few studies have compared the anti-shivering effects of different agents following coronary artery bypass graft (CABG). This study aims to compare the effects of dexmedetomidine and meperidine on the incidence of shivering in patients undergoing CABG.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Dexmedetomidine group

|
Active Comparator: Meperidine group
|
Drug: Meperidine
Meperidine would be intravenously injected at a dose of 0.5mg/kg 30 min before the end of surgery
|
Placebo Comparator: Control group
|
Drug: Placeb
Equal volume of normal saline to dexmedetomidine and meperidine group.

Outcome Measures
Primary Outcome Measures
- The incidence of postoperative shivering [Within postoperative 24 hours]
The incidence and severity of postoperative shivering and the rescue treatment
Secondary Outcome Measures
- Times of postoperative rescue drugs used [Within postoperative 24 hours]
- The incidence of postoperative hypotension and bradycardia [From the administration of experimental drugs to postoperative 24 hours]
- Ramsay sedation score [Within postoperative 3 days]
The minimum and maximum score are 1 and 6, respectively. Score 1 represents that patients is anxious and agitated or restless , or both. And score 6 represents that patients exhibits no response.
- Postoperative extubation time [The time of extubation]
- Length of stay in the ICU [The length of stay in ICU within postoperative 30 days]
- The incidence of postoperative delirium [Within postoperative 7 days]
- The incidence of postoperative arrhythmias [Within postoperative 24 hours]
- The incidence and severity of postoperative PONV [Within postoperative 3 days]
- Length of stay [The first day after surgery to discharge]
- The rate of all-cause death of participants [Within postoperative 30 days]
