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。
The results of brainstem auditory response (ABR) before and after treatment of 50 cases (94 ears) of iron deficiency anemia (IDA) were analyzed. IDA can cause peripheral damage of the auditory canal, which is mainly manifested as poor ABR waveform differentiation , The response threshold increased, the absolute prolongation of PL (PL) prolonged, and the peak-to-peak interphase (IPL) of a few children reached the threshold value, but no abnormality of IPL. All parameters of ABR returned to normal after iron treatment The change is reversible. Tip, early detection of children with IDA, early treatment.
