【摘要】 为探讨畸变产物耳声发射（DPOAE）在高危新生儿听力筛选方面的应用价值及其与听性脑干反应（ABR）的差异，用DPOAE和ABR两种方法对64例（128耳）高危新生儿进行听力筛选并比较。结果表明，DPOAE的敏感度为924％，假阴性率为7．6％；特异性为92．2％，假阳性率为7．8％。认为DPOAE具有客观、无创伤、快速、操作简便、特异性高、敏感性强等特点，尤其适用于高危新生儿听力筛选的初筛。更多还原

【Abstract】 64 neonates under intensive care have been tested by distortion product otoacoustic emisson (DPOAE) and the auditory brain stem response (ABR) to investigate the value of DPOAE as a test for hearing impairment. The DPOAE test has been found to be practical and quick to perform. The proportion of NICU infants producing a recordable DPOAE is 83. 6%,and the sensitivity and specificity to the ABR result is 92. 4% and 92.2%, false positive is 7. 8K,false negative is 7. 6% respectively. These figures are high enough and the reduction in time compared to ABR is sufficient for the DPOAE to be considered as the primary screen,firm conclusions on the sensitivity of DPOAE to long term hearing impairment await the results from larger numbers of infants and further follow up data.更多还原
