改良行为测听法筛查小婴儿听力障碍的探讨

Study on Screening Early Infant Hearing Loss by Improving Behavioral Audiometery

为对小婴儿早期进行听力监测.方法 采用改良行为测听法型(单项摇铃法)对2010名42天组婴儿进行测查.结果 有反应者1804人(89.4%).高危组有反应率45.2%,非高危组有反应率98.5%(P<0.01).影响婴儿听力的主要高危因素为噪声、母孕早期病毒感染、早产低体重.多高危因素儿、单高危因素几、无高危因素儿听力障碍可疑发生率有极显著差异(P<0.01).结论 表明单项摇铃法适用于小婴儿听力筛查.

To monitor early babies hearing. Methods Hearing of 2 010 babies aged 42 days were screered by a improving behavioral audiometery (Bell sound reaction). Results 1 084 babies had reaction (89. 8%). The reaction rate were 45. 9% in the high risk group and 98. 5% in the no high risk group ( P <0. 01). The main resons of negative reaction were noise, virus infection in early pregnancy, lower birth weight premature. Rates of hearing loss had significant differences among groups:muti-ple high risk factors, single high risk factor and no high risk factor( P <0. 01). Conclusion the improving behavioral audiometery can be applied to screening hearing of babies.
