摘　　要：目的总结飞行环境变压性眩晕的发病特点、发生机制和防治措施。方法回顾性分析7例飞行环境变压性眩晕患者的临床资料,并复习相关文献。结果①7例患者均在飞机上升或下降(采用瓦尔萨瓦操作)时存在明显气压变化过程中,出现典型的眩晕症状;②功能性者症状持续时间多在几秒到几分钟之间,有内耳器质性疾患者,症状持续时间可延长至数小时到数天;③除眩晕外,可伴前庭自主神经及耳蜗症状;④6例有明确的感冒、咽鼓管功能不良、飞行中多次压耳和晕车晕船等病史。结论飞行环境变压性眩晕为在气压明显变化的条件下产生的眩晕,可伴有前庭自主神经症状及耳蜗症状,可对飞行员造成极大的危害。Objective To summarize the common characteristics, mechanism and preventive measures of alternobaric vertigo. Methods The clinical data of 7 patients who had alternobaric vertigo in flying were retrospectively analysed. Relevant references were reviewed. Results All 7 cases reported the classic symptoms of vertigo during climbing up or during descending in the changing pressure environment for the forceful Valsalva maneuver. In addition, there were autonomic nerve symptoms and auditory symptoms. The duration of symptoms ranged form several sec to several min. Six cases had an upper respiratory infection, dysfunction of eustachian tube, otalgia in flying or motion sickness before or at the time. Conclusion Alternobaric vertigo is a syndrome that occurs in the changing pressure environment. The vestibular response, symptoms of the cochleae would be seen. It is a potentially serious hazard to flying safety.
