摘要 目的观察氯胺酮(KET)对急性下肢动脉栓塞手术取栓患者肢体缺血再灌注期间炎性细胞因子和自由基代谢的影响,探讨KET对急性下肢动脉栓塞肢体的保护作用。方法应用小剂量KET(观察组)及等量生理盐水(对照组)治疗30例急性下肢动脉栓塞手术取栓治疗患者。分别于麻醉后静注KET前(T1),手术取栓后5(T2)、20(T3)、30 h(T4)采血。应用放射免疫分析法测定TNF-α、IL-8浓度;应用黄嘌呤氧化酶法测定血清超氧化物歧化酶(SOD)活性,应用硫代巴比妥酸法测定血清丙二醛(MDA)浓度。结果两组TNF-α在T2、T3、T4各时点较基础值均明显升高(P〈0.05);观察组于T3、T4时点与对照组比较有显著统计学差异(P〈0.05)。两组IL-8在T3、T4时较基础值明显升高(P〈0.05),观察组于T3、T4时与对照组比较差异有统计学意义(P〈0.05)。对照组MDA在T2、T3、T4各时点较基础值均明显升高(P〈0.05);观察组MDA在T3、T4时明显升高(P〈0.05),观察组于T2-T4各时点MDA均较对照组低(P〈0.05)。观察组T2、T3,对照组T2、T3、T4时SOD均较基础值明显降低(P〈0.05)。结论KET能有效治疗下肢动脉栓塞引起的肢体缺血再灌注损伤。
