INCIDENCE OF SHIVERING DURING CESAREAN SECTION IN PATIENTS UNDER SPINAL ANESTHESIA WITH OR WITHOUT FENTANYL

Background & Aims: Postoperative shivering is one of the common complications of surgery in the recovery room, with an incidence rate of about 50-60% in various reports. Postoperative chills usually result in unwanted hypothermia during operation. Materials & Methods: In this study, patients were divided randomly (after selecting one of 32 card containing coatings) into intervention group (n=45) and the placebo group (n=45). This was done by anesthesiologist who had no intervention in the study, and anesthesiologist and patients did not receive information about the drugs received and the examination of chills and severity of chills was performed by a person who was not aware of the way of study. Results: There was a significant difference in the frequency of shivering between the intervention group (fentanyl) and the placebo group (without fentanyl) (p <0.001). There was no significant difference regarding severity of shivering between the intervention group and the placebo group (p = 450.0). There was no significant difference in vomiting between the intervention group and the placebo group (p=.184). There was a significant difference between the intervention group and the placebo group (p = 0.003) with regard to nausea. Because vomiting was only recovered in the placebo group (without fentanyl), there were 2 patients and in the intervention group (fentanyl), vomiting was not recovered at all. Therefore, no significant difference was observed regarding frequency of vomiting between the intervention group and the placebo group. There was no significant difference in the vomiting time between the intervention group and the placebo group (p = 0.69). There was a significant difference between the intervention group and the placebo group regarding pruritus (p <0.001). Conclusion: Most of the patients who received fentanyl had less shivering during surgery and recovery than those who did not receive fentanyl, and most of the patients who received fentanyl had less nausea during operation and recovery than those who did not receive fentanyl and those who received fentanyl have had more pruritus during operation and recovery than those who did not receive fentanyl. Also, taking fentanyl is effective in itching during surgery and recovery.
