肌注曲马朵和氟哌利多对低位硬膜外麻醉后寒战的影响

Prophylactic effect of tramadol and droperidol on shivering after epidural anesthesia

目的 :探讨肌内注射曲马朵和氟哌利多 (氟哌啶 )对硬膜外麻醉后寒战的预防效果。方法 :选择 6 0例准备在硬膜外麻醉下行下腹部、下肢或脊柱手术的成年患者 ,随机分为两组 :研究组 (T组 ,n =30 )和对照组 (C组 ,n =30 )。T组于硬膜外注药前 30min肌注曲马朵 1.5mg/kg和氟哌啶 5mg ;C组肌注同等容量的生理盐水。观察麻醉及手术过程中寒战的发生率、寒战的严重程度及寒战发生前后体温变化。结果 :T组寒战发生率为 3.3 % ,C组为 2 6 .7% ,两组比较有显著性差异 (P <0 .0 5 )。结论

Objectives:To study the effect of IM tramadol and droperidol in prevention of shivering after epidual anesthesia.Methods:60 elderly patients undergoing operations were randomly and equally divided to receive IM tramadol 1.5mg/kg and droperidol 5mg at 30 minutes before epidural anesthesia or equal volume of saline in the same condition.The incidence of shivering and its severity as well as temperature change were observed.Results:The incidence of shivering in the active group was 3.3% vs 26.7% in the control group.Significant difference existed between group( P <0.05).Conclusions:Intramuscular injection of tramadol and droperidol is helpful in prevention of shivering after epidural anesthesia.
