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 Decreases Shivering During Cesarean Delivery Under Spinal Anesthesia
Shivering associated with spinal anesthesia is uncomfortable and may interfere with monitoring . We performed this prospect i ve , double-blinded , and r and omized study to determine whether intrathecal meperidine ( 0.2 mg/kg ) decreases the incidence and intensity of shivering after spinal anesthesia for cesarean delivery . Forty parturients scheduled for nonemergent cesarean delivery were enrolled in two groups .  Spinal anesthesia consisted of hyperbaric bupivacaine ( 0.75 % ; 10.5 mg ) , morphine 0.15 mg , and , in the experimental group , meperidine ( 0.2 mg/kg ) or , in the control group , normal saline . Data collection , including sensory block level , blood pressure , core temperature , and shivering intensity , was performed every minute for 10 min , every 3 min for 33 min , and then every 5 min until the sensory level receded to L4 . Time to highest sensory level , maximum number of blocked segments , sensory and motor blockade regression , and systolic blood pressure showed no difference between groups . The incidence of shivering was less ( P < 0.02 ) in the meperidine group , as was its intensity ( P < 0.003 ) . Intrathecal meperidine ( 0.2 mg/kg ) is effective in reducing the incidence and intensity of shivering associated with spinal anesthesia for cesarean delivery
