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 injection of magnesium sulfate: shivering prevention during cesarean section: a randomized, double-blinded, controlled study
Background Regional anesthesia is known to significantly impair thermoregulation and predispose patients to hypothermia . We hypothesized that the addition of an intrathecal injection of magnesium sulfate ( MgSO4 ) to bupivacaine would improve perioperative shivering in female patients undergoing elective caesarean section . Methods In a block-r and omized , double-blinded , controlled trial 72 patients scheduled for elective caesarean section with spinal anesthesia were separated into two groups . In the treatment group , 2 ml of 0.5 % bupivacaine plus 25 mg MgSO4 ( 0.5 ml ) were injected intrathecally , and in the control group 2 ml of 0.5 % bupivacaine plus 0.5 ml normal saline were injected intrathecally . Core temperature was measured before and after drug injection at predetermined intervals . Sedation was grade d using the Ramsay sedation scale . Results No significant intergroup differences in appearance of shivering were seen immediately or at 5 , 30 , 40 , 50 , 60 , and 90 min after block administration . However , at 10 , 15 , and 20 min post block , there was a significant difference in shivering . The group administered MgSO4 showed lower shivering grade s compared with the control group . Core temperature was significantly reduced in the MgSO4 group compared to the normal saline group 30 min after blocking . Conclusions Intrathecal injection of MgSO4 improved perioperative shivering in female patients undergoing elective caesarean section
