3371例重症监护病房新生儿听力筛查结果分析

摘要

Objective To report factors in newborns failing hearing screening by analyzing automated auditory brainstem response (AABR) results from 3,371 newborns in the NICU at the Hunan Provincial Maternal and Child Health Care Hospital.Methods A total of 3,371 newborns in the NICU,born betwenn Jan 2016 and Dec 2016,were in-cluded in this study.All were screened by AABR.Rates of hearing screening failure and possible influential factors of were investigated.Those who failed to pass the hearing screening were followed up.Results There was no significant difference in the rate of failure between males and females (χ2=0.95,P=0.329).The failures were more common with multiple births (χ2=8.152,P=0.004),infection (χ2=13.845,P=0.000),hyperbilirubinemia (χ2=43.266,P=0.000),prema-ture birth(χ2=9.399,P=0.002)and low birth weight(χ2=5.076,P=0.024)were significantly higher than without these fac-tors;while the pass rate of the right ear was higher than that of the left ear(χ2=104.25,P=0.000).Hearing impairment was diagnosed by diagnostic audiology evaluation within 3 months of age in 13 cases.Conclusions Left ear,multiple births,infection,hyperbilirubinemia,premature birth and low birth weight appear to be risk factors for failing hearing screening.%目的 分析我院3371例重症监护病房新生儿自动听性脑干反应(AABR)听力筛查的结果,探讨影响NI-CU新生儿听力筛查阳性率的因素.方法 筛查对象为2016年01月至2016年12月湖南省妇幼保健院NICU收治的3371例新生儿,全部采用AABR进行听力筛查,计算筛查结果的阳性率,分析新生儿住院疾病因素与听力筛查阳性率之间的关系,并对确诊听力损伤的患儿进行追踪随访.结果 性别与新生儿听力筛查阳性率之间无显著差异(χ2=0.95,P=0.329);耳别、多胎、感染、高胆红素血症、早产、或低体重等因素与新生儿听力筛查阳性率之间均有统计学差异(耳别:χ2=104.25,P=0.000;多胎:χ2=8.152,P=0.004;感染:χ2=13.845,P=0.000;高胆红素血症:χ2=43.266,P=0.000;低体重:χ2=5.076,P=0.024;早产:χ2=9.399,P=0.002).复筛未通过且3月龄内确诊有听力损失者共13例.结论 耳别、多胎、感染、高胆红素血症、早产、低体重等可能是导致新生儿AABR听力筛查阳性率偏高的原因.
