摘要 对 50例 (94耳 )缺铁性贫血 (IDA)患儿治疗前后脑干听性反应 (ABR)的结果进行分析 ,认为 IDA可造成听传导路的周围性损害 ,主要表现为 ABR波形分化不良 ,反应阈值提高 , 、 、 波绝对潜伏期 (PL )延长 ,少数患儿的 - 峰间期 (IPL)达临界值 ,而 - IPL无异常 ,经补铁治疗后 ,ABR各参数恢复正常 ,说明这种改变是可逆的。提示 ,对小儿 IDA应早期发现 ,早期治疗。 Auditory brainstem response (ABR) was carried out in 50 infants (94 ears) with iron deficiency anemia (IDA) before and after iron supplementation.There were 32 males and 18 females,ranging in age from 6 months to 27 months.The results indicated that IDA resulted in peripheral lesion on auditory pathway.The main abnormality shown in ABR were as follows:(1) Elevated ABR thesholds and poor wave patterns;(2) Prolonged absolute latencies of wave Ⅰ,wave Ⅲ and wave Ⅴ;(3) Prolonged wave Ⅰ Ⅲ interpeak latencies which were in upper limit of normal range and normal wave Ⅲ Ⅴ interval.The blood indicators recovered to normal levels after 3 months of iron supplementation,and ABR parameters also returned to normal range,the result showed that the lesion of auditory pathway caused by IDA was reversible.Early diagnosis and treatment for IDA were important in children.
