785例新生儿听力筛查初筛结果分析

Analysis of 785 cases of newborn hearing screening results

目的 分析不同胎龄、不同体重新生儿听力筛查通过率的特点,为选择适当的初筛时间,提高初筛通过率提供依据.方法 对张家港市第—人民医院2011年11月～2012年3月出生的785例新生儿采用全自动耳声发射筛查仪进行听力筛查,按照不同年龄、体重对筛查结果进行总结分析.结果 785例新生儿中,初筛通过674例,占85.86％;初筛未通过111例,占14.14％;复筛通过16例,占2.06％.新生儿胎龄和体重与初筛通过率及假阳性率密切相关,差异有统计学意义（P＜0.05）.结论 根据新生儿出生时胎龄、体重的不同,选择合适的初筛时间,可有效提高初筛通过率,降低假阳性率的发生。

Objective To investigate the thruput of newborn hearing screening in different gestational age and different weight, and to improve the thruput in initial hearing screening. Methods Doing OAE （otoacoustic emisson） hearing screening for 785 infants born in the first people% hospital of Zhangjiagang from November 2011 to March 2012, and analyzing the results according to different gestational age and different weight. Results In 785 infants, 674 cases passed the initial hearing screening（85.86%）, 111 didn＇ t pass（14.14%） and the false positive rate was 2.06%. The pass rate and false positive rate were closely associated with gestational age and different weight, the difference are statistically significant （P〈0.05）. Conclusions To improve the quality of initial hearing screening, an appropriate examining time should be deteminated.
