创伤后多器官衰竭动脉血气监测的临床意义

Clinical Significance of Acid-base Disturbance and Arterial Blood Gases Analysis in Patients with Post-traumatic Multiple Organ Failure

报告了112例创伤后多器官衰竭（MOF）患者645例次动脉血气和血电解质测定结果。645例次血气分析中有620例次（96．1％）存在不同类型的酸碱失衡，其中单纯性酸碱紊乱264例次（42．6％），二重酸碱失衡260例次（41．9％），三重酸碱失衡96例次（15．5％）。MOF早期多为呼吸性碱中毒，并发低氧血症，随病情的加剧，可发生代谢性酸中毒，严重者可发生三重酸碱失衡。救治时，要针对治疗原发疾病和积极纠正脏器衰竭的同时，动态监测血气，同步测定血电解质，这对及时发现并纠正酸碱失衡与血电解质紊乱有重要意义。

Arteral blood-gas analysis and serum electrotyes detection were carefullycarried out 645 times from 112 patients with post-traumatic multiple organ failure (MOF).Acid-base disturbance of different types existed in 620 times (91. 5%) of 645 times blood-gasanalysis. There were 264 times (42.6%) of simple acid-base disorder, 260 times (41.95%)of double acid-base disturbance and 96 times (15. 5%) of triple acid-base disturbance. Ourdata showed that in the early stage of MOF respiratory alkalosis with or without hypoxemiamight be present, and later or, there might be metabolic acidosis or even triple acid-base disturbances. In order to detect and correct acid-base disturbances and electrolyte disorders asearly as possible, it is important to perform arterial blood-gas analysis and measure serumelectrolytes synchronously. Treatment of the primary disease is also of prime importance.
