摘要
采用左、右耳分別和两耳同时施声刺激从头顶Cz点记录方法,观察了30例正常儿童(NC)和60例脑瘫儿童(CCP)的听觉诱发脑干反应(ABR)。与NC相比,CCP的ABR发生明显异常(93.33％)表现为电压降低、潜伏时延K、左右两侧反应不对称和反应丧失等7种类型。经统计,除自身的ABR在左、右耳间波Ⅰ～Ⅴ、Ⅳ电压不等(P<0.05),波Ⅰ～Ⅴ、Ⅶ潜伏时差异显著(P<0.05)外,患侧波Ⅰ～Ⅴ,双侧的Ⅰ～Ⅴ、Ⅶ,对侧的Ⅱ、Ⅳ电压较NC低(P<0.05);患侧波Ⅰ～Ⅴ、Ⅶ的潜伏时延长(P<0.05)。结果提示:(1)CCP的听觉通路和脑干普遍受到损伤,且部位不定;(2)CCP的脑干和听觉通路损伤具有不对称性。
Auditory evoked brain stem responses (ABR)were recorded following left, right and binaural stimulation in 60 children with cerebral palsy (CCP) and 30 normal children(NC) subjects. The comparison of ABR between NC, and CCP showed serious abnormality (93.33%) and there were 7 abnormal types in the waves; amplitudes were reduced; latencies were prolonged; the asymmetry showed between left and right side responses; the responses lost, etc. The results suggested that not only remarkable disorder but also the asymmetries were presented in left and right brain stem and the auditory pathway of the CCP.
