本文应用脑干听诱发电位(BAEP)对66例有围产期脑损伤的智力低下(MR)患儿进行了听力测试。结果:48例 BAEP 异常,异常率为72.73%。有双侧或单侧损害,有周围性损害,也有中枢性损害,主要表现 I 波、V 波的潜伏期和峰间期延长。BAEP 的异常率与智力低下严重程度无关。提示:围产期脑损伤是造成 MR 和听力障碍的重要原因。BAEP 可做为一个客观指标有效地对 MR 患儿脑干功能进行评价,预测其听力状态,以达到早期发现,早期矫治的目的。
In this paper, brainstem auditory evoked potentials (BAEP) in 66 cases of perinatal brain damage in mental retardation (MR) in children with hearing tests. Results: 48 cases of abnormal BAEP, abnormal rate was 72.73%. There are bilateral or unilateral damage, peripheral damage, there are central lesions, the main performance I wave, V wave latency and peak interval extension. The abnormal rate of BAEP has nothing to do with the severity of mental retardation. Tip: Perinatal brain injury is an important cause of MR and hearing impairment. BAEP can be used as an objective indicator to evaluate brain stem function of MR children effectively and to predict its hearing status in order to achieve early detection and early correction.
