摘要：

探讨右美托咪定对单肺通气(OLV)过程中炎性反应及氧化应激反应的影响.方法择期行食管癌根治术患者40例,ASA Ⅰ或Ⅱ级,年龄45～64岁,体重指数＜30 kg/m2,随机均分为两组:右美托咪定组(D组)和对照组(C组).D组于气管插管后10 min开始静脉输注右美托咪定1 μg/kg(右美托咪定浓度为4μg/ml,输注时间10 min),随后以0.5μg·kg-1 ·h-1持续输注至关胸.C组静脉输注等容量生理盐水作对照.于OLV开始即刻(T0)、OLV后60 min(T1)和术毕(T2)采集肘静脉血,检测丙二醛(MDA)浓度和超氧化物歧化酶(SOD)的水平,酶联免疫法检测TNF-α和IL-6的浓度.结果与T0时比较,T2时两组血清SOD活性降低,MDA、TNF-α和IL-6的浓度升高(P＜0.05)；与C组比较,D组血清SOD活性升高,MDA、TNF-α和IL-6的浓度降低(P＜0.05).结论右美托咪定可抑制单肺通气过程中炎性反应和氧化应激反应,对临床实践中进行肺保护具有积极作用. 　　Effect of dexinedetomidine on inflammatory response and oxidative stress during one-lung ventilationZHANG Wei,ZHANG Jia-qiang,MENG Ean-min .Department of Anesthesiology.Henan ProvincalPeople's Hospital .Zhengzlzou 450003,ChinaCorresponding author:ZHANG Wei,Email:myhope2005@I63.com[Abstract] Objective To observe the effect of dexmedetomidine on inflammatory response andoxidative stress during one-lung ventilation. JZetbods Forty patients,ASA工or } ,aged 45-64,withbody mass index lower than 30 kg'm=.were randomly divided into two groups（}:一20）：　　dexmedetomidine group （group D） and control group（group C），Dexmedetomidine 1 }g/kg wereinfused 10 min after tracheal intubation, followed by continous infusion of dexmedetomidine at rate ofo. 5 ;}g“kg-' ”h-' .Normal saline with equal volume were administrated in group C. Venous bloodsamples were obtained at three time points: the beginning of OI_V, 60 min after （）LV and the end ofoperation. MDA, SOD, TNF-a and IL-6 were detected. Results Compared to T .the activity of SODwere decreased, the plasma concentration o于MDA, TNF-a and工L-6 were increased in both groups at T} 　　（PGO. 05）；Compared to group C, the activity of SOI）were increased in group D, the plasma concentrationof MDA, T'}F-a and II} 6 were decreased at T= CP}O. 05）。 Conclusion Dexmedetomidine could inhibitinflammatory response and oxidative stress during one-lung ventilation in patients udergoing elective resectionof esophageal carcinoma, it has positive effect on the lung protection in clinical process.
