目的：脑干听觉反应（ABR）测试通常在自然睡眠中进行，但它也可以在麻醉状态下进行。这项回顾性研究旨在比较全身麻醉组和对照组在自然睡眠期间进行ABR测试的脑干听觉诱发电位结果。

方法：麻醉组由42名（平均年龄44.5±20.3个月）儿童组成，对照组包括58名儿童（36.1±16.1个月）。两组的点击ABR测试结果在振幅、潜伏期、峰间潜伏期和听力阈值方面进行了比较。

结果： 与对照组相比，全身麻醉组的III和V波的振幅明显下降。与对照组相比，麻醉组的I和V波的ABR潜伏期以及I-V和III-V的峰间潜伏期都延长了。此外，麻醉组获得的点击阈值也明显高于对照组。

结论：临床医生和听力学家应建议家属了解全身麻醉对ABR的影响，并在解释麻醉下进行的ABR测试的结果时要谨慎。

Effect of General Anesthesia on Auditory Brainstem Response Testing

Abstract 

Objective: The auditory brainstem response (ABR) test is usually applied during natural sleep, but it can also be conducted under anesthesia. This retrospective study aimed to compare the ABR findings of a general anesthesia group and a control group that underwent ABR test during natural sleep.

Methods: The anesthesia group consisted of 42 (mean age 44.5±20.3 months) children, and the control group included 58 children (36.1±16.1 months). The results of the click ABR test of the two groups were compared in terms of amplitude, latency, interpeak latencies, and hearing thresholds.

Results: The amplitudes of waves III and V were significantly decreased in the general anesthesia group compared with that in the control group. The ABR latencies of waves I and V and the interpeak latencies for I-V and III-V were prolonged in the anesthesia group compared with that in the control group. Moreover, the click threshold obtained in the anesthesia group was significantly higher than those of the control group.

Conclusions: Clinicians and audiologists should advise families to know the effects of general anesthesia on ABR and be cautious in interpreting the results obtained in ABR test performed under anesthesia.
