Abstract

UNLABELLED

Click-evoked oto-acoustic emissions (CEOAE) are acoustic responses produced by the inner ear, reflecting functional auditory integrity. We studied both the success rate of the CEOAE method and the CEOAE presence in preterm infants during their stay at the Neonatal Intensive Care Unit (NICU), by analysis of the results of longitudinal CEOAE measurements in 19 preterm infants. The CEOAE method proved to be feasible in the majority of the population under study; the CEOAE measurement failed in 8% of the total of 226 attempts. Within the range of 30-40 weeks post-conceptional age (PCA) the CEOAE presence increased from about 50% to 80%. These results show the possible clinical application of CEOAE in a NICU for the monitoring of cochlear function during treatment of preterm infants.

CONCLUSION

Bedside CEOAE measurement in preterm infants in a NICU is feasible at a PCA as low as 30 weeks.

瞬态诱发耳声发射（CEOAE）是内耳产生的声学反应，反映听觉功能的完整性。我们通过分析19例早产儿的纵向CEOAE测量结果，研究了CEOAE方法在早产儿入住新生儿重症监护病房（NICU）期间的成功率以及CEOAE的存在情况。CEOAE方法在大多数研究人群中被证明是可行的；在226次尝试中，有8%的CEOAE测量失败。在孕龄（PCA）30 - 40周范围内，CEOAE的存在率从约50%增加到80%。这些结果表明，CEOAE在NICU中可能具有临床应用价值，可用于监测早产儿治疗期间的耳蜗功能。
