目的:对听力筛查选出有听力障碍的新生儿进行现状分析。方法:对32 682例(65 364耳)新生儿分别在出生后72 h、42天用畸变产物耳声发射进行听力测试筛选,有异常者在3～6月龄前用诱发电位及多频稳态进行检测诊断。结果:32 682例(65 364耳)新生儿经过听力筛查选出听力障碍者120例,为0.36%;其中轻、中度98例,为0.30%;重度以上者22例,为0.067%。结论:新生儿窒息乏氧、孕早期的病毒感染、家族性遗传、缺氧性脑病为新生儿听力障碍的主要因素,孕期用耳毒类药物、新生儿高胆红素血症、父母吸烟饮酒、孕期接触电脑及耳部畸形次之。
OBJECTIVE: To analyze the current situation of hearing screening screening of newborns with hearing impairment. Methods: 32 682 newborns (65 364 ears) were tested by audiological testing with distorted otoacoustic emissions at 72 h and 42 d after birth respectively. The abnormalities were induced by evoked potentials and multi-frequency stabilization before 3 to 6 months of age State for testing diagnosis. Results: 32 682 (65 364 ears) newborns were selected through hearing screening, 120 of them (0.36%) were hearing impaired, of which 98 cases were mild and moderate, 0.30%; Conclusions: Neonatal asphyxia, hypoxia, viral infection in early pregnancy, familial inheritance and hypoxic encephalopathy are the main factors of neonatal hearing impairment. Pregnancy with ototoxic drugs, neonatal hyperbilirubinemia, smoking and drinking by parents Pregnancy contact with computers and ear malformations followed.
