目的探讨早产儿听力检测的临床意义。方法对2003年5月~2005年9月在本院儿科和母婴同室住院的137例早产儿(其中无合并症早产儿67例、有合并症早产儿70例)和对照组足月新生儿2152例采用畸变产物耳声发射(DPOAE)进行听力检测,早产儿组初检时间为出生后3~5d,复检时间为出生后42d和90d;对照组初检时间为出生后3~5d,发现听力异常者在出生后42d和90d进行复检。如3次检测均未通过者,进行脑干诱发电位(ABR)检测。结果早产儿组听力障碍4例,异常率为2.92%,足月儿组听力障碍2例,异常率为0.09%,早产组与足月儿组比较,差异具有统计学意义(P<0.05);有合并症早产儿组异常率为5.71%,无合并症早产儿组异常率为0,有合并症组与无合并症组比较,差异具有统计学意义(P<0.05)。结论早产儿尤其是有合并症的早产儿是发生听力障碍的高危群体。
Objective To investigate the clinical significance of hearing test in preterm infants. Methods A total of 137 preterm infants (67 premature infants with no comorbidities and 70 premature infants with comorbidities) who were hospitalized in our hospital from May 2003 to September 2005 in pediatric and maternity infants in our hospital and full term newborn infants 2152 cases of distortion product otoacoustic emissions (DPOAE) for hearing testing, premature infants group initial examination time is 3 ~ 5d after birth, retest time is 42d and 90d after birth; control group initial examination time is 3 ~ 5d after birth, Found abnormal hearing after 42d and 90d after re-examination. If none of the three tests, the brain stem evoked potential (ABR) test. Results There were 4 cases of hearing loss in preterm group, with an abnormal rate of 2.92%. There were 2 cases of hearing loss in full - term children group with an abnormal rate of 0.09%. There was significant difference between preterm group and full - term group (P <0.05). The rate of abnormality in premature infants with comorbidity was 5.71%. The rate of abnormal premature infants without comorbidity was 0. The difference was statistically significant (P <0.05) in patients with comorbidity and without comorbidity. Conclusion Preterm infants, especially those with comorbidities, are at risk for hearing loss.
