【摘要】 目的探讨电耳镜诊断高压氧所致中耳气压伤的临床实用性。方法首次进行高压氧治疗的患者300例,高压氧治疗第1天进舱前用麻黄碱滴鼻对潜在的中耳气压伤进行干预,治疗出舱后采用金标准法、电耳镜检法、传统方法诊断是否有中耳气压伤。结果高压氧治疗第1天后金标准法、电耳镜法、传统方法分别诊断高压氧治疗致中耳气压伤26例(8.67%)、26例(8.67%)、72例(24.00%)。电耳镜法诊断高压氧治疗致中耳气压伤的特异度、准确度、真阴性率等指标均高于传统方法。结论电耳镜检查客观而准确,可及时窥视鼓膜病变,利于早期诊断和处置中耳气压伤。更多还原

【Abstract】 Objective To explore the clinical practicability of electronic otoscopy in the diagnosis of middle ear barotrauma caused by hyperbaric oxygen(HBO) therapy.Methods Three hundred patients who received HBO therapy for the first time were treated with ephedrine nasal drops as the intervention for potential middle ear barotrauma on the first day of HBO treatment,and three methods including the gold standard,electronic otoscopy and traditional method were adopted in the diagnosis of middle ear barotrauma after HBO treatment.Results Twenty-six cases(8.67%) were diagnosed as middle ear barotrauma caused by HBO therapy according to the gold standard on the first day after HBO treatment while twenty-six cases(8.67%) were diagnosed by electronic otoscopy and seventy-two(24.00%) cases were diagnosed with traditional method.The specificity,accuracy and true negative rate of electronic otoscopy were significantly higher than those of traditional method in the diagnosis of middle ear barotrauma caused by HBO therapy.Conclusion Electronic otoscopy is objective and accurate,and can help to find tympanum lesions in time,which benefits early diagnosis and treatment of middle ear barotrauma.更多还原
