婴幼儿耳聋的脑干听觉诱发电位特征(英文)

Characteristics of brain stem auditory evoked potential in infant deafness

背景:脑干听觉诱发电位为婴幼儿耳聋的诊断提供客观依据,也使早期听力筛选及时分辨外周或脑干的病变成为可能。目的:探讨脑干听觉诱发电位(brainstemauditoryevokedpotential,BAEP)特征对婴幼儿耳聋早期评估的意义。设计:以诊断为依据的观察性研究。地点和对象:2000-10/2003-05惠州市中心人民医院门诊及住院的患者80例,男48例,女32例,年龄37周～4岁,平均2.5岁。方法:采用丹麦DANTECKEYPOTNT肌电图诱发电位仪对80例有语言障碍的患儿进行BAEP检查,并对结果进行分析。主要观察指标:Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ波潜伏期,Ⅰ～Ⅲ波峰间期,Ⅲ～Ⅴ波峰间期,Ⅲ～Ⅴ,Ⅰ～Ⅲ波峰间期比值。结果:80例160只耳中,正常耳30只,异常的130只耳中周围性通路异常92耳,蜗后病变38耳。其中周围性通路异常分别为轻度12耳、中度25耳、重度损害55耳。结论:BAEP检查可以判断早期婴幼儿耳聋听觉通路损害的意义。

BACKGROUND:Brain stem auditory evoked potential(BAEP) provides an objective gist for the diagnosis of infant deafness,which also makes early auditory screening to differentiate peripheral or brain stem pathological changes in time become possible. OBJECTIVE:To investigate the significance of BAEP characteristics in the early evaluation of infant deafness. DESIGN:An observatory trial based on diagnosis. SETTING and PARTICIPANTS:Eighty patients from Outpatient and Inpatient Departments of Huizhou Central People's Hospital from October 2000 to May 2003 were selected including 48 male and 32 female cases aged from 37 weeks to 4 years old with a mean age of 2.5 years old.
