The desirability of finding children with hearing impairment after bacterial meningitis as soon as possible prompted us to examine the feasibility of using evoked otoacoustic emissions (EOAE) as an in-patient check of hearing status in children recovering from bacterial meningitis. Sixty-six episodes of bacterial meningitis were studied. Traces could be recorded for only 54.7% of ears. All children subsequently found to have sensorineural hearing impairment who were tested with EOAE, failed the screening test. The low coverage of the screening test and the predicted low specificity due to the high incidence of conductive hearing impairments, lead us to conclude that, with the technology currently available, the measurement of EOAE after bacterial meningitis is not a practical method for a pre-discharge check of hearing. Every effort must still be made to ensure all children are referred for an appropriate auditory assessment.
尽快发现患有细菌性脑膜炎后听力受损儿童的迫切需求促使我们研究将耳声发射（EOAE）作为细菌性脑膜炎康复期儿童住院听力状况检查方法的可行性。我们研究了66例细菌性脑膜炎病例。仅54.7%的耳朵能够记录到痕迹。随后发现所有经EOAE检测有感音神经性听力损失的儿童筛查试验均未通过。由于传导性听力障碍的高发病率导致筛查试验的低覆盖率和预计的低特异性，我们得出结论，就目前可用的技术而言，细菌性脑膜炎后EOAE的测量并非出院前听力检查的实用方法。仍必须尽一切努力确保所有儿童都能接受适当的听力评估。
