目的分析总结早产儿听力筛查结果,以便及早发现听力障碍早产儿,早期干预,改善预后。方法采用瞬态诱发耳声发射(TEOAE)听力筛查仪,对257例早产儿在生后3-7d进行听力初筛,对于未通过的早产儿,1个月后复查,仍未通过者于生后3个月进行脑干听觉诱发电位检测确诊。结果共检查257例早产儿,初筛通过161例,初筛通过率62.65%,复筛通过53例,复筛总通率83.27%,复筛未通过42例,三个月进行脑干听觉诱发电位(ABR)检查时30例正常,12例异常,听力障碍发生率为4.67%。结论早产儿听力障碍发病率高,是听力损失的高危人群,应重点监测,早期干预治疗。
Objective To analyze and summarize the results of hearing screening in premature infants in order to detect early premature infants with hearing impairment, early intervention and improve prognosis. Methods Twenty-five preterm infants were pretreated with hearing at 3-7 days after birth by transient evoked otoacoustic emission (TEOAE) audiogram. For premature infants who did not pass, one month later, they were still not passed Three months after birth, brainstem auditory evoked potentials were detected. Results Totally 257 preterm infants were examined. The initial screening passed 161 cases, the initial screening pass rate was 62.65%, the number of re-screening was 53, the total re-screening rate was 83.27%, the re-screening did not pass 42 cases, and brainstem auditory evoked 30 cases were normal in ABR examination, 12 cases were abnormal, and the incidence of hearing impairment was 4.67%. Conclusion The incidence of hearing loss in preterm infants is high, which is a high risk group of hearing loss. Key monitoring and early intervention should be given.
