The results showed that , compared with placebo , pethidine , fentanyl , dexmedetomidine , and sufentanil significantly reduced the incidence of perioperative shivering .
In addition , compared with sufentanil , fentanyl showed no impact on haemodynamic stability and the incidence of pruritus .
CONCLUSION Pethidine , fentanyl , dexmedetomidine , and sufentanil appear to be effective for preventing perioperative shivering in puerperae undergoing cesarean sections .
Considering the risk-benefit profiles of the included neuraxial adjuvants , fentanyl is probably the optimal choice
BACKGROUND Perioperative shivering is clinical ly common during cesarean sections under neuraxial anesthesia , and several neuraxial adjuvants are reported to have preventive effects on it .
However , the results of current studies are controversial and the effects of these neuraxial adjuvants remain unclear .
AIM To evaluate the effects of neuraxial adjuvants on perioperative shivering during cesarean sections , thus providing an optimal choice for clinical application .
Incidence of shivering after cesarean section under spinal anesthesia with or without intrathecal sufentanil: a randomized study.
BACKGROUND AND OBJECTIVES Shivering is a cause of discomfort and dissatisfaction in patients undergoing cesarean section . The objective of this study paper was to assess the impact of intrathecal administration of sufentanil on the incidence of shivering after cesarean section . METHOD In a prospect i ve blinded , r and omized clinical trial , pregnant women undergoing cesarean section under spinal anesthesia were enrolled . Pregnant women in labor , febrile , obese , with pregnancy-induced hypertension , anesthetic block failure or surgical complications were excluded . Patients were r and omly assigned to two groups . In Group I , 10 mg of 0.5 % hyperbaric bupivacaine combined with 80 mcg of morphine and 2.5 mcg of sufentanil were administered . In Group II , 10 mg of 0.5 % hyperbaric bupivacaine combined with 80 mcg of morphine were administered . In the post-anesthesia care unit , patients were evaluated for signs of shivering by an investigator blinded to the patient 's group allocation . RESULTS The sample consisted of 80 patients . In both groups there was a decrease in axillary temperature of patients after cesarean section ( p<0.001 ) . This decrease was not different between groups ( p<0.21 ) . In Group I , the incidence of tremor was 32.5 % ( 13/40 ) and in Group II it was 62.5 % ( 25/40 ) ( p<0.007 ) ; RR 0.53 ( CI 95 % 0.32 - 0.87 ) . CONCLUSIONS It has been suggested that the addition of sufentanil to hyperbaric bupivacaine and morphine during spinal anesthesia for cesarean section provides a decrease in the incidence of shivering in the immediate postoperative period
