Pulmonary Barotrauma in Diving Accidents

潛水意外事件之肺擠壓傷害

摘要


潛水人員在使用壓縮空氣進行潛水時,不當的減壓上升會造成肺臟擠壓傷害,是大家非常了解的。在減壓疾病中,肺臟擠壓傷害約佔了16%;為造成潛水死亡案件中,第二位最常見的致死因素。肺臟擠壓傷害的臨床症狀包括:肺臟過度膨脹傷害、氣胸、縱膈腔氣腫及最嚴重的後遺症即空氣栓塞症。本研究共收集了六位罹患肺臟擠壓傷害的病歷,肺臟擠壓傷害後產生的結果:肺臟過度脹氣四位、空氣栓塞症一位、縱膈腔氣腫一位。造成肺臟擠壓傷害之原因:憋氣上升三位、操作浮力袋不慎導致充氣緊急上升二位、因故緊急上升一位、。臨床症狀包括:意識昏迷一位、胸痛併胸悶五位、呼吸困難三位、咳血二位。五位病患經高壓氧治療表六A治療後病患痊癒、其中一位昏迷病患經高壓氧治療表六A-1治療後症狀改善僅留有耳鳴之後遺症。

Pulmonary barotrauma (PBT) of ascent is a well known complication in compressed air diving. It amounts to 16% of decompression illness cases and is the second largest death in diving accidents .Clinical features of PBT are pulmonary overinflammation damage, pneumothorax, mediastinal emphysema, and the most serious sequela is the arterial gas embolism (AGE). In the respective survey, 6 cases of PBT were analysed. Clinical features of PBT were pulmonary overinflation (n=4), arterial gas embolism (n=1), and mediastinal emphysema (n=1). The reason of causing of PBT were breath-hold ascent (n=3), buoyancy ascent (n=2), emergency ascent (n=1). Clinical signs and symptoms onset time was less than 5 minutes after surfacing in 5 cases, in one case it was within 10 minutes. Precipitating dive factors were buoyancy ascent (n=2), emergency ascent (n=1), and breath-hold ascent (n=3). After US Navy Table 6A (hyperbarix oyxgen treatment table), 5 cases were cured .One coma case received US Navy Table 6A-1 with improvement only tinnitus residual symptom.
