Treatment of Shivering during Epidural Anesthesia by Pethidine, Pethidine Droperidol or Tramadol

Objective: To evaluate the efficacy and side effect of pethidine, pethidine droperdol or tramadol in the treatment of shivering during epidural anesthesia. Methods: 60 ASA I adult shivering patients undergoing elective surgery under low thoracolumbar epidural anesthesia were allocated randomly to receiving intravenous pethidine 0.5mg/kg (group I, n=20), pethidine 0.5mg/kg and droperidol 0.05mg/kg (group II, no=20) or tramadol 2mg/kg (group III, n=20). Shivering was observed after intravenous drugs. Results: The overall effective rates in three groups were 85%, 95% and 95% respectively. The onset times in group II and group III were significantly shorter than that in group I ( P 0.01).SpO 2 was improved significantly after shivering was stopped ( P 0.01). Conclusion: All groups can cure shivering during epidural anesthesia. Tramadol was weak on sedition, which was better for the patients with heart-pulmonary function disorder than that in the other groups.
