目的了解复筛未通过婴儿自动听性脑干诱发电位(AABR)筛查结果,分析影响AABR筛查结果的相关因素,比较AABR与瞬态声耳声发射(TEOAE)两种筛查方法的差异。方法选取2014年3月20日-2015年2月13日合肥市各县(区)妇幼保健所听力复筛未通过的361名婴儿为对象进行AABR筛查,采用卡方检验分析地区、性别、年龄及耳别对AABR筛查结果的影响。结果复筛未通过婴儿AABR筛查未通过率为44.6%。AABR未通过率经卡方检验,在性别、年龄、地区3个方面比较,差异均无统计学意义(P>0.05)。左耳未通过率高于右耳,且差异具有统计学意义(P<0.05)。AABR未通过率明显低于TEOAE未通过率,且两者差异具有统计学意义(P<0.05)。结论 AABR是一种有效的听力筛查方法,特别是对于复筛未通过婴儿进行后续的听力学评估之前,应用AABR筛查可有效降低假阳性率,提高筛查准确性,减轻部分家长不必要的精神负担和经济负担。
OBJECTIVE: To investigate the effect of AABR screening on AABR screening and to compare the difference between AABR and TEOAE . Methods A total of 361 infants who failed to pass the hearing screening in MCH counties (districts) from March 20, 2014 to February 13, 2015 were screened for AABR. Chi- square test was used to analyze regional, gender, and age And ear to AABR screening results. Results The failed screening rate of AABR screening failed to reach 44.6%. The AABR failed rate by chi-square test, in terms of gender, age, area of three aspects, the difference was not statistically significant (P> 0.05). The failure rate of the left ear was higher than that of the right ear, and the difference was statistically significant (P <0.05). The failure rate of AABR was significantly lower than that of TEOAE, and the difference was statistically significant (P <0.05). Conclusion AABR is an effective method of hearing screening. Especially for the follow-up audiological assessment of non-adoptive screening of re-screening, AABR screening can effectively reduce the false-positive rate, improve screening accuracy and reduce the unnecessaryness of some parents Mental burden and financial burden.
