摘　　要：目的:研究耳声发射(OAE)筛查早产儿听力的基本特征,寻找适合早产儿听力筛查的方法、首次听力筛查的时间及评定标准。方法:应用丹麦产M adsen Cape ila耳声发射仪,对112例早产儿进行畸变产物耳声发射测试(DPOAE),测试结果不能通过者,1个月后复查,仍不能通过者3个月复查,如仍不能通过则同时行脑干诱发电位(ABR)检查,并对112例早产儿按窒息、体重及黄疸分组。结果:总通过率为86.6%,窒息组DPOAE通过率明显低于其他组,差异有显著性(P<0.05)。结论:DPOAE快速、方便、无损伤,可作为早产儿听力筛查的有效方法,且测试结果与窒息密切相关,胎龄34周是早产儿听力成熟的关键年龄,早产儿首次听力筛查的合适时间为胎龄34周,对第1次不能通过DPOAE的早产儿,尚不能断定为听力障碍,定期复查、随访很重要。Objective： To investigate the basic properties of otoacoustic emissions （OAE） in premature, search for a method of premature hearing screening, a optimal time and a evaluation criteria. Methods： Distortion product otoacoustic emissions （DPOAE） was used for hearing screening in 112 premature. The characteristics of DPOAE in premature were analyzed. Results： Pass rate was 86.6%. The pass rate of asphyxia group was very lower then that of study group. Conclusion： DPOAE is an objective, rapid and noninvasive technique, and it is the first choice of hearing screening in premature. 34 weeks of gestational age is a critical age for the auditory development. The first tested time of hearing screening in premature is 34 weeks of gestational age. Follow - up is very important.
