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 .
Effects of intrathecal dexmedetomidine on shivering after spinal anesthesia for cesarean section: a double-blind randomized clinical trial
Background Shivering is among the common troublesome complications of spinal anesthesia ( SA ) , and causes discomfort and discontentment in parturients undergoing cesarean sections ( CSs ) . The aim of this study was to investigate the effects of intrathecal dexmedetomidine in the prevention of shivering in those who underwent CS under SA . Subjects and methods Fifty parturients planned for elective CSs under SA were enrolled in this prospect i ve , double-blinded , controlled study and r and omly divided into two equal groups . Spinal block was achieved with 12.5 mg 0.5 % heavy bupivacaine plus 5 μg dexmedetomidine ( BD group ) or 0.5 mL 0.9 % normal saline ( BN group ) . The incidence and intensity of shivering , peripheral and core body temperature , hemodynamic parameters , and adverse events was recorded . Results The incidence of shivering was significantly higher in the BN group ( 52 % ) than the BD group ( 24 % ) ( P=0.04 ) . Likewise , the intensity of shivering was significantly higher in the BN group than the BD group ( P=0.04 ) . The incidence of adverse events , such as hypotension , nausea/vomiting , and bradycardia , was not significantly different between the two groups , although the grade of sedation was higher in the BD group than the BN group ( P=0.004 ) . Conclusion We conclude that intrathecal dexmedetomidine is effective in lowering the incidence and intensity of shivering in parturients undergoing CSs under SA without major adverse effects
