交通、建筑及自然灾害所致创伤时有发生,严重创伤后发生低氧血症可达90%~[1],组织缺氧状态持续时间过长,将导致不可逆的损害及内环境紊乱,引发一系列的链式病理生理过程,进而发展为多器官功能衰竭,最终导致死亡。低氧血症能否在短时间内得到纠正,决定患者的预后,因其伤情的发生发展与转归受到缺氧病理生理改变的影响,在缺氧的高原地区,体现得尤其重要。现总结我院急诊科救治创伤后低氧血症经验,为其救治提供一定 Transportation, buildings and natural disasters caused by trauma have occurred, severe traumatic hypoxemia up to 90% ~ [1], hypoxia duration of tissue is too long, will lead to irreversible damage and internal environment disorders, triggering A series of chained pathophysiological processes, which in turn develop into multiple organ failure, eventually lead to death. Hypoxemia can be corrected in a short time, to determine the prognosis of patients, because of the occurrence and development of injuries and prognosis by the impact of hypoxia pathophysiological changes in the hypoxic plateau region, is particularly important. Are summarized in our hospital emergency department treatment of post-traumatic hypoxemia experience, to provide some treatment
