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 .
Intrathecal fentanyl for prevention of shivering in spinal anesthesia in cesarean section
Background Shivering is one of the common problems in spinal anesthesia . The objective of the present study was to evaluate the effect of intrathecal fentanyl ( 25 µg ) on incidence and severity of intraoperative and postoperative shivering . Methods A double-blind r and omized controlled study was conducted in eighty healthy women ( ASA Physical status I ) scheduled for elective cesarean section under spinal anesthesia . Subjects were r and omly divided into two equal groups . The patients received 12.5 mg ( 2.5ml ) of 0.5 % hyperbaric bupivacaine combined with 25 µg ( 0.5 ml ) fentanyl in Group F as a study group and 12.5 mg ( 2.5ml ) of 0.5 % hyperbaric bupivacaine combined with 0.5 ml normal saline in Group S as a control group . Incidence of shivering during 30 and 60 minutes of surgery and recovery and complications were evaluated . Results The total incidence of shivering in Group F was significantly lower than Group S ( 10 % in group F ; 75 % in group S , p < 0.0001 ) . Almost all patients started shivering in the first hour after spinal anesthesia and the rate of shivering especially in second 30 minutes was higher than first 30 minutes in both groups . None in Group F but 22 patients ( 55 % ) in Group S had shivering during recovery and all of them reported shivering at the first 30 minute at recovery . The severity of shivering in Group F was significantly lower than Group S ( p < 0.0001 ) . Conclusion Intrathecal bupivacaine combined with fentanyl is associated with a lower incidence and severity of shivering
