本文分析2555例因各种原因进行脑干听觉诱发电位检查所发现的听力障碍儿1082例.17.6％的听力障碍由高危因素引起。本文列举了各种听力障碍高危因素,其中重度窒息占46.8％,高胆红素血症占20.5％。其他常见原因为早产、低出生体重、精神运动发育迟缓、遗传代谢病,耳毒性药物也占一定比例。各种原因引起的听力障碍中,除耳毒性药物引起者以重度听力障碍为主外,其他常见原因均以轻、中度听力障碍为主。故早期发现、早期干预,充分发展残余听力,执行康复计划,可充分提高高危儿的生命质量。本文初步探讨了听力障碍早期诊断的关键及早期干预的原则.
This article analyzes 1,055 children with hearing impairment found in 2555 cases of brainstem auditory evoked potentials for various causes, and 17.6% of hearing disorders are caused by high-risk factors. This article lists a variety of risk factors for hearing loss, with severe asphyxia accounting for 46.8% and hyperbilirubinemia accounting for 20.5%. Other common causes are premature birth, low birth weight, mental retardation, hereditary metabolic diseases, and ototoxic drugs. Among the various causes of hearing impairment, except for those with ototoxicity caused by severe hearing impairment, other common causes are mild and moderate hearing impairment. Therefore, early detection and early intervention, fully develop the residual hearing, the implementation of rehabilitation programs, can fully improve the quality of life of high-risk children. This article initially explores the key to early diagnosis of hearing impairment and the principle of early intervention.
