Assessing infants' hearing is of utmost importance, as hearing at this phase is required for the development of oral language. Through hearing, human beings are capable of developing communication. The Brainstem Auditory Evoked Potentials are an indispensable test to diagnose deafness in infants. This study aimed to analyze the results of the Brainstem Auditory Evoked Potentials in children with risk factors for hearing loss.
This cross-sectional study analyzed the Brainstem Auditory Evoked Potentials in 123 infants aged 1 to 24 months at a hearing health care service. The Vivosonic Integrity V500 equipment, which enabled the child to be awake while the testing was carried out, was used in this study. The data were compared by gestational age and sex, according to the standards suggested in the equipment handbook.
A significant difference was verified for age ranges 4 to 6 months, 13 to 15 months (waves I and V), and 7 to 9 months (wave V). The lower values in absolute wave latencies were comparable to data from the equipment handbook, justifying the need for standardization of the screening process.
There are some differences between the standards in the equipment handbook and those observed in our study. These results will serve as a reference for the standardization of the equipment used in the hearing health care service.
评估婴儿的听力至关重要，因为在此阶段，听力是发展口语的必要条件。通过听力，人类能够发展沟通。脑干听觉诱发电位是诊断婴儿耳聋不可或缺的测试。本研究旨在分析有听力损失风险因素的儿童的脑干听觉诱发电位结果。
本横断面研究分析了在听力保健服务中年龄在 1 至 24 个月的 123 名婴儿的脑干听觉诱发电位。本研究使用了 Vivosonic Integrity V500 设备，该设备使儿童在测试过程中保持清醒。根据设备手册中的标准，根据胎龄和性别对数据进行比较。
在 4 至 6 个月、13 至 15 个月（波 I 和 V）和 7 至 9 个月（波 V）的年龄范围内，差异具有统计学意义。绝对波潜伏期的较低值与设备手册中的数据相当，证明了筛查过程标准化的必要性。
设备手册中的标准与我们研究中观察到的标准之间存在一些差异。这些结果将为听力保健服务中使用的设备的标准化提供参考。
