lntraoperative dexmedetomidine administration at the end of surgery prevents post anesthetic shivering

Objective To examine the efficacy of the alpha 2 agonist, Dexmedetomidine in prevention of postoperative shivering. Methods Seventy ASA І-II patients were included in this randomized-prospective double blinded study. They were allocated into two groups to receive either Dexmedetomidine as a loading dose of 1 ug/ kg for 10 min or normal saline 20 minutes before the end of the surgery. Shivering and sedation were assessed postoperatively. Results Demographic data were similar in both groups. Incidence of shivering was found to be significantly less in Dexmedetomidine group; 4 (12%) patients had some degree of shivering in comparisons to 16 (48%) in saline group (P
