目的了解东海县新生儿先天性听力损伤发生情况。方法新生儿出生后3~7 d采用畸变产物耳声发射仪(DPOAE)进行初筛,初筛阳性及具有听力损伤高危因素者42 d后采用DPOAE联合自动听性脑干诱发电位(AABR)复筛,复筛阳性者采用DPOAE+AABR+听觉脑干反应(ABR)+声导抗确诊,并确定听力障碍程度和性质。结果 2009年7月—2013年6月出生的79 825例新生儿中,接受初筛76 127例,初筛率95.37%,初筛阳性率5.34%;复筛3 409例,复筛阳性率12.47%,确诊听力损伤113例,占筛查总数的1.48‰,中重度听力损伤52例,占听力损伤总数的46.02%。结论应加强宣传教育,提高群众对新生儿先天性听力损伤的重视程度,提高筛查率和筛查质量。
Objective To understand the occurrence of congenital hearing impairment in Donghai County. Methods Newborns were screened by DPOAE at 3-7 days after birth. DPOAE combined with automatic auditory brainstem response (AABR) was used after 42 days of primary screening and high risk factors of hearing impairment Screening, positive screening were DPOAE + AABR + auditory brainstem response (ABR) + acoustic impedance diagnosis, and to determine the degree and nature of hearing impairment. Results Of the 79 825 newborns born between July 2009 and June 2013, 76 127 were initially screened, with a primary screening rate of 95.37% and a positive screening rate of 5.34%. A total of 3 409 rescreening tests showed a positive rate of 12.47 %, 113 cases of hearing loss were diagnosed, accounting for 1.48 ‰ of the total screening, 52 cases of moderate to severe hearing impairment, accounting for 46.02% of the total number of hearing impairment. Conclusion Publicity and education should be stepped up to raise public awareness of neonatal congenital hearing impairment and to improve the screening rate and screening quality.
