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 Meperidine Plus Lidocaine for Prevention of Shivering during Cesarean Section
Background Shivering related to spinal anesthesia may interfere with monitoring and is uncomfortable . The aim of the present study was to investigate low-dose intrathecal meperidine for the prevention of shivering after induction of spinal anesthesia in parturients with cesarean section . Methods This was a prospect i ve r and omized , double-blind , placebo-controlled trial including 100 parturients , of American Society of Anesthesiologists ( ASA ) physical status I or II , scheduled for elective cesarean section under spinal anesthesia who were r and omly assigned to a meperidine ( 0.2 mg/kg ) plus hyperbaric lidocaine ( 5 % , 75 mg , n = 50 ; group M ) group or a placebo plus hyperbaric lidocaine ( 5 % , 75 mg , n = 50 ; group L ) group . Demographic and surgical data , adverse events , and the mean intensity for each parturient were assessed during the entire study period by a blinded observer . Results There were no significant differences between the two study groups regarding the demographic and surgical data ( P > 0.05 ) . The incidence of shivering during the entire study period significantly decreased in the group of parturients who received intrathecal meperidine ( P = 0.04 ) . There were no significant differences in nausea and vomiting between the two groups . Conclusions Low-dose intrathecal meperidine ( 10 mg ) is safe and effective in reducing the incidence and severity of shivering associated with spinal anesthesia in parturients with cesarean section
