模拟轻潜水耳气压伤与内耳减压病实验研究

Study of Ear Barotrauma and Inner Ear Decompression Disease in 60 m Diving

为研究60m轻潜水对内耳的影响,本实验以豚鼠为研究对象,开放左耳听泡,模拟60m潜水正常及快速减压,应用听生理学、形态学、活体微循环的研究方法证明:开放听泡避免耳气压伤后,中耳、内耳未见病理生理学改变,亦未见内耳微循环的血液流变学改变,提示在60m轻潜水的减压过程中,耳蜗、前庭功能的损害以耳气压伤为主,较少发生内耳减压病.

In order to study the effect of safe and rapid decompression in 60 m diving to theinner ear, the guinea pigs with left bulla opened were exposed to the 7 ATA air pressure. It wasobserved that there are no physiological and pathological changes in the inner and middle ear afterthe bulla opened, and also no changes in the inner ear microcirculation with the method of live mi-crocirculation. We concluded that in 60 m decompression, ear damage is mainly from barotrauma,but seldom from decompression.
