ABSTRACT
Shivering is a common post anesthesia complication. Intravenous Clonidine administration at induction of anesthesia is a useful drug for decreasing of incidence and severity of post-anesthesia shivering. As Clonidine injection can induce side effects therefore we evaluated the oral Clonidine premedication on post-anesthesia shivering. In a RCT, 60 adult patients in ASA class 1 and 2 scheduled for cholecystectomy were assigned to 2 groups. 2 hours before anesthesia, 0.2 mg oral Clonidine was administrated and to the other group placebo was administered. Surgery room temperature was adjusted for 21-23[degree][c]. At the end of the anesthesia, the patients' shivering was evaluated in the recovery room by "Crossley andMahajan shivering score". There was no difference at decrease of SpO2 and H.R. and MAP between 2 groups. There was no difference in average time of emergence between 2 groups. Overall 75% of the patients shivered after anesthesia. Median shivering score in clonidine group was 1.97 and in placebo were 2.87. It became revealed that there was clear difference at shivering score between 2 groups [less severe or generalized shivering patients in test group]. 0.2 mg Clonidine tablet, 2 hours before anesthesia is similar to injecting drug and is effective in prevention of post-anesthesia shivering but its complication is less. Lack of difference at hemodynamics and SpO2 and emergence in our study may be due to slow absorption of oral Clonidine
