肌注曲马朵和氟哌利多对低位硬膜外麻醉后寒战的影响

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60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26.7％，两组比较有显著性差异（P<0.05）。结论肌注曲马朵和氟哌啶有助于预防低位硬膜外麻醉后寒战。

Prophylactic effect of tramadol and droperidol on shivering after epidural anesthesia

Objectives:To study the effect of IM tramadol and droper idol in prevention of shivering after epidual anesthesia.Methods:60 el derly patients undergoing operations were randomly and equally divided to receiv e IM tramadol 1.5mg/kg and droperidol 5mg at 30 minutes before epidural anesthes ia or equal volume of saline in the same condition.The incidence of shivering an d 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 gro up.Significant difference existed between group(P<0.05).Conclusions:Intramuscular injection of tramadol and droperidol is helpful in prevention of shivering after epidural anesthesia.
