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

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
