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 .
The Effects of Preemptive Tramadol and Dexmedetomidine on Shivering During Arthroscopy
Background : Shivering , the rate of which in regional anesthesia is 39 % is an undesired complication seen postoperatively . Aims : This study aims to compare the ability of preventing the shivering of preemptive tramadol and dexmedetomidine during the spinal anesthesia ( SA ) . Methods : A total of 90 patients with American Society of Anesthesiologists physical status I-II , aged 18 - 60 years and undergoing elective arthroscopic surgery with SA were divided into three groups r and omly . After spinal block , 100 mg tramadol in 100 ml saline was applied in group T- ( n = 30 ) and 0.5 μg/kg dexmedetomidine in 100 ml saline was applied in group D- ( n = 30 ) and 100 ml saline was administered in group P- ( n = 30 ) in 10 min . The hemodynamics , oxygen saturation , tympanic temperature , shivering and sedation scores were evaluated and recorded intraoperatively and 45 min after a postoperative period . Results : In group T and D , shivering scores were significantly lower when compared with group P in the intraoperative 20th min ( P = 0.01 ) . Sedation scores in group D were significantly higher than the baseline values ( P = 0.03 ) and values in group T and P ( P = 0.04 ) . Conclusions : Preemptive tramadol and dexmedetomidine are effective in preventing the shivering under SA . In addition , dexmedetomidine was superior in increasing the level of sedation which is sufficient to prevent the anxiety without any adverse effects
