Auditory brainstem response (ABR) was used to assess possible hearing loss in 60 patients recovering from bacterial meningitis. The ABR results were consistent with either unilateral or bilateral hearing loss in 35% of the cases tested. Of these, 15% were conductive-type hearing loss. Twelve percent had sensorineural hearing losses and normal brainstem function. The remaining 8% had elevated ABR thresholds coincident with findings suggestive of neuropathology of the auditory brainstem pathways. A case of reversible sensorineural hearing loss was documented. Various clinical and demographic factors were examined to determine their predictive value with regard to hearing loss. As expected, otitis media occurred significantly with conductive hearing loss. Type of pathogen (Streptococcus pneumoniae) and hospitalization greater than two weeks were significantly correlated with sensorineural hearing loss. As meningitis typically affects young children who are difficult to test with conventional audiometry, ABR provides an effective means of testing hearing in this population.
采用听性脑干反应（ABR）评估60例细菌性脑膜炎康复患者可能存在的听力损失。在接受测试的病例中，35%的ABR结果与单侧或双侧听力损失相符。其中，15%为传导性听力损失。12%为感音神经性听力损失且脑干功能正常。其余8%的ABR阈值升高，同时伴有提示听觉脑干通路神经病理学改变的表现。记录了1例可逆性感音神经性听力损失病例。研究了各种临床和人口统计学因素，以确定它们对听力损失的预测价值。正如预期的那样，中耳炎与传导性听力损失显著相关。病原体类型（肺炎链球菌）和住院时间超过两周与感音神经性听力损失显著相关。由于脑膜炎通常影响难以用传统听力测定法进行测试的幼儿，ABR为该人群的听力测试提供了一种有效的方法。
