BACKGROUND
This study compared distortion product otoacoustic emissions (DPOAEs) and click-evoked auditory brainstem responses (ABRs) recorded from infants whose mother had Covid-19 during pregnancy (Covid-19 group) to infants whose mother did not have Covid-19 (Control group) during pregnancy.
METHODS
This study retrospectively examined records of infants in the Covid-19 group (n = 15) and control group (n = 46) who had distortion product otoacoustic emissions (DPOAEs) and click-evoked auditory brainstem responses (ABRs) recorded as part of their clinical assessment. DPOAE amplitudes, absolute latencies (I, III, and V), and I-V interpeak intervals were examined.
RESULTS
DPOAE amplitudes were similar between the Covid-19 group and the control group. The absolute latency of wave I was similar between groups. But absolute latencies III and V and I-V interpeak intervals of the Covid-19 group were significantly prolonged compared to the control group.
CONCLUSION
Covid-19 infection and its complications during pregnancy may not affect the cochlear function but may affect the functioning of the auditory brainstem.
背景
本研究比较了患有新冠病毒感染孕妇（新冠病毒组）所产婴儿和未感染孕妇（对照组）所产婴儿的畸变产物耳声发射（DPOAE）和短声诱发听性脑干反应（ABR）。
方法
本研究回顾性分析了新冠病毒组（n=15）和对照组（n=46）婴儿的记录，这些婴儿的畸变产物耳声发射（DPOAE）和短声诱发听性脑干反应（ABR）是其临床评估的一部分。检查了 DPOAE 幅度、绝对潜伏期（I、III 和 V）以及 I-V 峰间间期。
结果
新冠病毒组和对照组的 DPOAE 幅度相似。两组的 I 波绝对潜伏期相似。但是，新冠病毒组的 III 波和 V 波以及 I-V 峰间间期的绝对潜伏期明显长于对照组。
结论
孕妇感染新冠病毒及其并发症可能不会影响耳蜗功能，但可能会影响听觉脑干的功能。
