Evaluatiion of remifentanyl infusion on postanesthetic shivering during rhinoplasty surgery in emem reza hospital

According to increasing rate of rhinoplastic surgery and need to dry field for this operation. Also since the remifentanyl is one of the best drugs in such operation we have done this study to evaluate one of its side effects (postanesthetic shivering) on patients. It was a randomized clinical trial. In this study 60 patients who were candidate for elective surgery under general anesthesia randomly allocate to two groups (remifentanyl and control groups). The results were presented as the mean ± SD. Then data from prevalence and duration of postanesthetic shivering was analyzed with Chi – square and and T-Student tests and by 18 version of SPSS software. Two groups were similar with demographic parameters such as age، and sex (P>0. 05). In the remifentanyl group frequency of postanesthetic shivering was higher and duration of it was more in remifentanyl group (P<0. 05). Remifentanyl infusion can cause higher rate of postanesthetic shivering than control group.
