1、临床麻醉学杂志2014年2月第3O卷第2期JClinAnesthesiol,February2014,Vo1.30,No.2.临床研究.右美托咪定抑制全麻下止血带相关反应的临床研究李永华陈巍羊黎晔王成才石学银【摘要】目的探讨右美托咪定(DEX)是否可以有效抑制止血带相关高血流动力学反应,降低RPP。方法全身麻醉下行单侧膝关节置换术患者80例,ASAI~Ⅲ级,随机分为右美托咪定组(D组,7"/一41)和对照组(C组,=39)。常规麻醉诱导后七氟醚吸入维持麻醉,调节其浓度,维持BIS值40~60。D组给予Igg/kg负荷剂量(20mi
2、n)后以0.4g·kg·h维持,C组予以等量生理盐水。比较麻醉诱导前(To)、止血带充气即刻(T)、充气后20rain(T2)、充气后30min(,r3)、充气后40min(T4)、充气后50rain(T;)、充气后6Omin(T6)HR、SBP、RPP、BIS、CrrSev和MAC。结果与C组比较,D组T2~Ts时HR明显减慢,SBP、RPP明显降低(P3、时,MAC在T3~T时均明显降低(P<0.05)。结论右美托咪定可显著抑制止血带相关高血流动力学反应,减慢HR、降低SBP,减少RPP并降低MAC和CErSev,减少七氟醚吸入剂量。【关键词】右美托咪定;止血带;止血带相关高血压elinicalresearchofdexmedetomidinehydrochloridefortourniquetrelatedproblemsundergeneralanesthesiaLIYong-hua,a删wi,YANGLi-ye,WANGCheng-cai,JXue-yin.Departmen4、tAnesthesiology,ShanghaiChangzhengHospital,Shanghai200003,ChinaCorrespondingauthor:.IXue-yin,Emaif:shixueyin1128@163.corn[Abstract]ObjectiveToevaluatewhetherdexmedetomidine(DEX)couldinhibittourniquetinducedhighhemodynamicresponseorreduceRPP.AndwhetherDEXhasimpactonthe5、minimumalveolar(MAC)andend-tidalconcentrationofsevoflurane(CrrSev).MethodsEightypatientsundergoingtotalkneearthroplastyoperation,AsAI—II1wererandomizedintotwogroups:groupD(DEX,,2—41)andgroupC(saline,”一39).Afterinductionofgeneralanesthesia,sevofluranewasinhaledtomainta6、intheBISvalueof40—60.IngroupD,acontinuousinfusionofDEX(1ug/kgfor2OminutesforloadingdoseandfollowedbyO.4g·kg一·h一)wasusedtilltheendofsurgery,whereasgroupCreceivedanequivalentvolumeofsaline.HR,SBP,RPP,BIS,CrrSevandMACvaluesofsevofluranewererecordedbeforeinduction(To),rig7、htafterinflation(T1),20min(T2),30min(Ta),40min(T4),50min(T5),6Omin(T6).ResultsComparedwithgroupC,HR,SBP,RPPofgroupDweresignificantlyloweratT2一T6(P8、luraneingroupDweresignificantlylowerthanthoseofthegroupCatT4一Ts(P<0.05).C~dmimDexmedetomidinecouldsignificantlydecreasethein
