Objective: This study was done for comparative study of dexmedetomidine with that o tramadol and pethidine in the treatment of post-neuraxial
anaesthesia shivering.
Design: This was a prospective, randomised, double-blinded study.
Setting And Subjects: Hundred patients of both genders, aged 18–70 years with American Society of Anesthesiologists physical status I and II
undergoing neuraxial a( spinal or combined spinal and epidural)anaesthesia for elective surgery were enrolled in this study. Sixty of them
developed shivering after an intrathecal injection of 0.5% hyperbaric bupivacaine 15 mg. They were then randomly allocated to receive either
intravenous dexmedetomidine 0.5 μg/kg, pethidine 0.5 mg/kg or tramadol 0.5 mg/kg.
Outcome measures: The response rate to treatment, the degree of sedation and the side-effects were recorded.
Results: The response rate to treatment was highest in the dexmedetomidine group, and it was only signicant when compared to tramadol group
(p = 0.0012). It was noted that the response rate was higher in the pethidine than in the tramadol group. This difference was not statistically
signicant (p = 0.082). The sedation score post treatment was similar in all three groups, but more patients in the dexmedetomidine group
developed hypotension and bradycardia (p< 0.05).
Conclusion: Dexmedetomidine 0.5 μg/ml was more effective than tramadol 0.5 mg/ml and pethidine 0.5 mg/ml, and both tramadol and pethidine
were found to have similar efcacy, in the treatment of post-neuraxial anaesthesia shivering. However, dexmedetomidine caused a higher
incidence of hypotension and bradycardia.
