脑干听觉诱发电位和脑血流动力学对脑瘫的临床评估探讨【摘要】目的探讨脑干听觉诱发电位和脑血流动力学变化对脑瘫(CP)的临床评估价值。方法收集脑瘫患儿70例,分为轻型组、中型组、重型组三组。采用脑干听觉诱发电位检测I波、III波、V波的潜伏期,I〜III波、IV〜V波、I〜V波的波峰间潜伏期,并采用经颅多普勒超声技术检测脑内动脉平均血流速度(Vm).动脉搏动指数(PI)、血管阻力指数(RI)的变化。结果脑瘫患儿重型组和中型组的脑干听觉诱发电位异常表现以潜伏期或波峰间潜伏期延长明显,分别为13例(18.6%)和16例(22.9%),与轻型组比较,差异有统计学意义(P<0.05);同时,中型组和重型组Vm均降低,与轻型组比较,差异冇统计学意义(P〈0.05或0.01);中型组和重型组PI、RI均升高,与轻型组比较,差异有统计学意义(P〈0.05或0.01)o结论脑干听觉诱发电位联合脑血流动力学检测对CP的早期诊断、病情判断和预后等可提供有价值的参考。【关键词】脑干听觉诱发电位;脑血流动力学;脑瘫中图分类号:R748文献标识码:ADOI:10.3969/j.issn.10031383.2015.05.002Clinicalcvaluationofbrainstemauditoryevokedpotentialandcerebralhemodynamicsforcerebralpalsy[HJ2][HJ]HUANGYueyan,LIQingfeng,PANHongfei,LIQiang,TANGHanqing,HUANGYunfeng,YOUJinyong,HUANGKen(AffiliatedHospitalofYoujiangMedicalUniversityforNationalities,Baise533000,Guangxi,China)[HJ2][HJ][Abstract】ObjectiveToexploreclinicalevaluationofbrainstemauditoryevokedpotentials(BAEP)andcerebralhemodynamicsforcerebralpalsy(CP)・Methods70childrenwithCPwerecollectedanddividedintomilddegreegroup,middledegreegroupandseveredegreegroup.AndthenBAEPwasusedtodetectpeaklatency(PL)ofwaveI,waveIIIandwaveVaswellasinterpeaklatency(IPL)ofwaveI~III,waveIV~VandwaveI〜V.Inaddition,meanflowvelocityofcerebralartery(Vm),arterialpulsationindex(PI)andvascularresistanceindex(RI)weredetectedthroughtranscranialDoppler(TCD)・ResuItsAbnonnalBAEPwasfoundin13cases(18.6%)inseveredegreegroupand16cases(22.9%)inmiddledegreegroup,whichshowedthattheyobviouslyproIongatedinPLandIPL,anddiffereneewasstatisticallysignificantwhencomparingtothoseinmilddegreegroup(P<0.05).Inaddition,Vmofmiddledegreegroupandseveredegreegroupdecreased,andtherewasstatisticallysignificantor0.01)•However,PIandRIinbothseveredegreegroupandmiddledegreegroupincreased,differencewasstatisticallysignificantwhencomparingtothoseinmilddegreegroup(P<0.05or0.01)•ConclusionBAEPcombinedwithcerebralhemodynamicscanprovidevaluablereferenceforearlydiagnosis,conditionjudgmcntandprognosisofCP.[Keywords]BAEP;cerebralhemodynamics;CP缺血缺氧造成的脑损伤常常是小儿脑性瘫痪(cerebralpalsy,CP)、新生儿缺氧缺血性脑病(hypoxicischemicencephalopathy,HIE)等脑损伤疾病的主要病理基础。脑干听觉诱发电位(brainstemauditoryevokedpotentials,BAEP)是临床上判断脑功能常用的神经电生理检查方法,具有敏感性强、无损伤等优点;脑血流动力学改变对于脑缺血缺氧程度判断冇重要参考价值,为探讨BAEP变化联合脑血流动力学改变对小儿缺氧缺血性脑损伤病情和治疗预后的指导价值,本研究回顾性分析70例脑瘫患儿的BAEP和脑血流动力学检测结果并进行讨论,报道如下。1资料与方法1.1临床资料选取2010年10月至2014年6月在我院接受治疗的脑瘫患儿70例。按照有关脑瘫的定义和分型判断标准[1]。病例纳入标准:BAEP异常;粗大运动功能分级I〜III级;认知功能正常;心、肝、肾功能正常;凝血功能正常。排除标准:有先天性遗传性耳聋病;颅内感染;脑外伤;有遗传代谢性疾病;有应用耳毒性药物史患儿;中毒性脑病。70例脑瘫患儿年龄10-36个月,平均(11.82±4,56)个月,男40例,女30例。脑瘫痉挛型48例,混合型4例,肌张力低下型8例,手足徐动型10例。轻型21例,中型26例,重型23例。本研究与患儿家属签...
