Abstract
Postoperative Shivering, reported to be of up to 66% prevalence, can cause serions complications such as over consumption of oxygen , vascular cowstriction, myocardial disorders and cerebral pressure increase. In this study, the effect of oral clonidine on postoperative shivering has been studied. 86 patients of class I and II surgery were randomly assigned into clonidine and placebo groups in this clinical trial. The former received 5 g/kg oral clonidine 90 to 120 minutes prior to surgery and the latter received similar pills with no clonidine. Anaesthesia was the same. The patients were observed at recovery for their shivering. The results indicated that the two groups were homogeneous across their age, sex, BMI, type and duration of surgery, bp and body temperaturye. Postoperative shivering in placebo group was 24.1% while it was reduced to 6.3% in the Clonidine group. Therefore, oral Clonidine is Recommended as a supplement to pre - and Post operative caregivings in order to decrease shivering and its complications.
