1、山东大学硕士学位论文重度子痫前期硫酸镁治疗前后子宫动脉、脐动脉、大脑中动脉血流变化研究姓名:贾苒申请学位级别:硕士专业:妇产科学指导教师:王谢桐20120501重度子痫前期硫酸镁治疗前后子宫动脉、脐动脉、大脑中动脉血流变化研究专业妇产科学硕士研究生贾苒导师王谢桐教授中文摘要目的:观察重度子痫前期硫酸镁治疗前后子宫动脉、脐动脉、大脑中动脉血流变化,从而为硫酸镁治疗重度子痫前期提供科学的客观评价指标。方法:收集2010年7月至2011年2月济宁医学院附属医院收治的50例重度子痫前期患者,同时随机选取40例正常妊娠妇女作为对照组。所有孕妇平
2、均年龄28.04士3.35岁,平均孕龄33.47士2.19周,均无原发性高血压、肝肾疾病及心脑血管疾病。两组孕妇年龄及孕龄无显著性差异。静脉注射硫酸镁及用后48d'时行超声检查,除硫酸镁外未应用其他血管活性药物。记录孕妇心率,收缩压,舒张压(DBP)和平均动脉压(MAP)的变化。应用彩色超声多普勒技术检测子宫动脉和脐动脉收缩期最大血流速度与舒张末期血流速度之}=L(S/D)、搏动指数(PI)和阻力指数(RI)。应用经颅多普勒技术检查测定孕妇大脑中动脉收缩期最大血流速度(Vs)、舒张末期血流速度(Vd)、平均血流速度(Vm)、PI和RI
3、。根据公式灌注压(CPP)=[Vm/(Vm-Vd)](MAP.DBP),计算脑灌注压(CPP)。结果:1.静脉使用硫酸镁48d,时后,重度子痫前期患者收缩压及舒张压无明显降低;患者心率明显加快,差异有统计学意义沪4、P在正常范围,17例CPP增高。硫酸镁治疗后,CPP增高者CPP明显降低(尸.<0.05),CPP诈常及减低者无明显变化(尸l>O.05)。结论:1.重度子痫前期患者应用硫酸镁后收缩压及舒张压无明显变化,但增加患者心率。2.硫酸镁可明显降低重度子痫前期患者子宫动脉PI、RI和S/D值。3.硫酸镁大脑中动脉灌注压有调节作用。关键词:重度子痫前期;硫酸镁;子宫动脉;脐动脉;大脑中动脉;多普勒超声出盘厶堂亟±堂位i金室Changesofuterine,umbilicalandmiddlecerebralarteriesbloodflowby5、magnesiumsulfateinseverepreeclampsiaSpecialityObstetricandGynecologyPostGraduateJiaRanTutorProf.WangXietongABSTRACTObjective:ToevaluateDopplerparametersofuterine,umbilicalandmiddlecerebralarteriesbeforeandaftermagnesiumsulfateadministrationinpregnantwomenwithseverepreec6、lampsia,andprovideascientificbasisforthetreatmentofseverepreeclampsia.Methods:50womenwithseverepreeclampsiaand40normalpregnantwomeninJuly2010toFebruary201fromaffiliatedhospitalofJiNingmedicalcollegeparticipatedinthestudy.Meanmaternalagewas28.04:t:3.35yearsandmeangestati7、onalagewas33。47+2.19weeks.Allwomenhadnoessentialhypertension,renaldiseaseorcardiovascularandcerebrovasculardiseases.Therewerenosignificantdifferenceintheageandgestationalweeksinthetwogroups.DopplerultrasonographySCanSwereperformedbeforeand48hoursafterintravenousadminist8、rationofmagnesiumsulfate,novasoactivedrugsotherthanMgS04weregiven.Maternalparameterssuchasheartrate,andsystoli
