酒石酸布托啡诺用于分娩镇痛最佳剂量探r£三=-1[摘要]目的:比较采用不同剂量酒石酸布托啡诺联合甲磺酸罗哌卡因用于硬膜外分娩镇痛的疗效及安全性。方法:选择我院2009年6月〜2010年6月主动要求行分娩镇痛、健康、单胎、足月临产初产妇100例随机分成四组,A组采用0.002%酒石酸布托啡诺和0.1788%甲磺酸罗哌卡因;B组采用0.004%酒石酸布托啡诺和0.1788%甲磺酸罗哌卡因;C组采用0.006%酒石酸布托啡诺和0.1788%甲磺酸罗哌卡因;D组采用0.1788%甲磺酸罗哌卡因。采用视觉模拟疼痛评分(VAS),记录两组疼痛程度、疼痛开始缓解时间(T1)、疼痛完全缓解持续时间(T2)、产程时间、分娩方式、新生儿Apgar评分及不良反应情况。结果:随着布托啡诺浓度的提高,T1逐渐缩短,与D组比较,B、C组T1明显缩短。随着使用布托啡诺剂量的增加T2延长,与D组比较,B、C组T2明显延长。结论:0.004%酒石酸布托啡诺和0.1788%甲磺酸罗哌卡因用于分娩镇痛为最佳剂量且有效安全。[关键词]酒石酸布托啡诺;甲磺酸罗哌卡因;分娩镇[中图分类号]R614[文献标识码]A[文章编号]1673-7210(2010)10(b)-055-03toJune2010,100patientsofepiduralanalgesiainlabor,hea1th,singlefetalandthetermoftheEffectexplorationondifferentdosageofButorphanolTartrateinlabouranalgesiaSHENXiaoqin,LUANChunmei(DepartmentofAnesthesiology,TaizhouPeople'sHospitalofNantongUniversity,Taizhou225300,China)[Abstract]Objective:TocomparetheefficacyandsafetyofButorphanolTartrateandRopivacaineMesylateinlabouranalgesia・Methods:FromJune2009anddividedAgroupwith0.002%provisionalmaternalwereenrolledrandomlyintofourgroups,ButorphanolTartrateand0.1788%RopivacaineMesylate;Bgroupwith0.004%ButorphanolTartrateand0.1788%RopivacaineMesylate;Cgroupwith0.006%ButorphanolTartrateand0.1788%RopivacaineMesylate;Dgroupwith0.1788%RopivacaineMesylate.Thenvisualanaloguescales(VAS),theinitiating(Tl)andlasting(T2)timeofeffectiveness,thetimeoflaborcourse,thepainofchildbirth,modeofdelivery,motornerveblockandotherindicatorswereobservedandcomparedbetweentwogroups.ResuIts:ButorphanolTartratedecreasedT1andincreasedT2.T1inBandCgroupswereshorterthanthatinDgroup.T2inBandCgroupswerelongerthanthatinDgroup.Conclusion:ButorphanolTartratecanprovideeffectiveanalgesiainlabouranalgesiawithfewersideeffects,especiallywhenthedosageof0.004%ButorphanolTartrateand0.1788%ropivacainemesylatewasused.[Keywords]ButorphanolTartrate;RopivacaineMesylate;Labouranalgesia硬膜外镇痛药配伍局麻药,已经广泛应用于分娩镇痛,效果较为满意[1]。酒石酸布托啡诺与甲磺酸罗哌卡因,分别作为新型的混合型阿片受体激动药与长效酰胺类局麻药,其用于分娩镇痛的可行性还需明确。为此,本研究比较不同浓度的酒石酸布托啡诺与甲磺酸罗哌卡因联合应用于分娩镇痛,以分析其最佳剂量与副作用,为临床选择提供依据。1资料与方法1.1一般资料将我院2009年6月〜2010年6月间主动要求行分娩镇痛、健康、单胎、足月临产初产妇100例随机分成4个治疗组。两组产妇无产科合并症,无阴道分娩禁忌证以及硬膜外麻醉禁忌证,年龄、体重、孕周比较,差异均无统计学意义(P>0.05),见表lo1.2镇痛方法观察组待产妇在宫口开2〜3cm时,先行阴道检查无异常,由麻醉医师选择L2〜3或L3〜4椎间隙行硬膜外腔穿刺并向头侧置管3〜4cm,回抽无返流后注入1.3%盐酸利多卡因3ml,严密观察5min无蛛网膜下腔阻滞和局麻药中毒,确认导管在硬膜外腔后,首次注入配置的麻醉混合液5ml[A组:50ml中含1.192%甲磺酸罗哌卡因(山东鲁抗)7.5ml、酒石酸布托啡诺(江苏恒瑞)1mg,即终浓度为0.1788%甲磺酸罗哌卡因和0.002%酒石酸布托啡诺;B组:50ml中含1.192%甲磺酸罗哌卡因7.5ml、布托啡诺2mg;C组:50ml中含1.192%甲磺酸罗哌卡因7.5ml、布托啡诺3mg;D组:50ml中含1.192%甲磺酸罗哌卡因7.5ml]。将导管连接于微电脑自控输注泵,以后视产妇...
