【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。
[Abstract]:Objective to summarize the pathogenesis, mechanism, prevention and treatment of pressure vertigo in flight environment. Methods the clinical data of 7 patients with variable pressure vertigo in flight environment were analyzed retrospectively and the related literatures were reviewed. Results all the 17 patients had typical vertigo symptoms during the process of aircraft rising or falling (Valsawa operation). (2) the duration of symptoms in functional patients lasted from a few seconds to a few minutes, and the duration of symptoms could be extended to several hours to several days in patients with organic diseases of inner ear, and (3) in addition to vertigo, it could be accompanied by symptoms of vestibule autonomic nerve and cochlea. 46 cases had a definite history of cold, eustachian tube dysfunction, multiple ear pressing and seasickness during flight. Conclusion variable pressure vertigo in flight environment is vertigo caused by obvious change of air pressure, which can be accompanied by vestibule autonomic nerve symptoms and cochlear symptoms, which can cause great harm to pilots.
