畸变产物耳声发射用于新生儿听力筛查的影响因素分析

目的 探讨畸变产物耳声发射(DPOAE)用于新生儿听力筛查的影响因素。方法 采用GSI-70全自动便携式耳声发射仪进行新生儿听力筛查，在筛查同时，自制问卷表，对新生儿的出生史，母亲妊娠史，家族史，父母社会阶层等35个因素进行调查，调查结果运用SPSS统计软件进行统计分析。结果 住院期间82．8％的(3242／3944)新生儿通过筛查，通过率右耳高于左耳，女婴高于男婴，单胎高于多胎，足月儿高于早产儿，正常及高出生体重儿高于低出生体重儿，阴道助产高于自然产、剖宫产，P值均小于0．05。多因素logistic回归分析，出生体重、性别、胎数与初筛结果相关。42天复筛，96．4％(3167／3284)通过筛查，影响初筛结果的因素对复筛无影响。结论 新生儿的性别、分娩方式、胎数、孕周、出生体重对应用DPOAE进行的新生儿听力筛查的初筛结果有显著影响。

Factors Affecting Distortion Product Otoacoustic Emisson in Newborn Hearing Screening

Objective To seek the factors affecting distortion product otoac oustic emisson in newborn hearing screening. Methods All newborns in our hospital received hearing sc reening by DPOAE and wer e investigated for the factors such as: birth history, pregnancy history, family history, the social position of the family. All data were analysed by SPSS. Results 82.8%(3 242/3 944) newborns passed the hearing sc reening. Pass rates were h igher in right ears, female baby, monocyesis, normal or high birth weight and fo rceps delivery. The Results of the first hearing screening were correlated with birth weight,sex and fetus number by logistic regression. Conclusion The factors suc h as sex, ways of labor, fetus number, fetus age, and birth weight can affect t he results of first hearing screening significantly.
