This study aims to compare the effects of dexmedetomidine and meperidine on the incidence of shivering in patients undergoing CABG.
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.
