目的：探讨急性肺损伤（ALI）、急性呼吸窘迫综合征（ARDS）、全身炎症反应综合征（SIRS）和多器官功能障碍综合征（MODS）的临床意义，并观察ARDS的酸碱失衡类型及糖皮质激素的疗效。方法：回顾性研究临床病例。结果和结论：①ARDS患者病死率（51．3％）显著高于ALI（20．5％），提示区分ALI与ARDS对于临床防治具有一定意义；②感染和创伤是诱发SIRS的常见因素，SIRS的严重程度与MODS的发生及ALI和ARDS的预后有关；③ARDS患者的酸碱失衡发生率高达98．3％，并以混合性酸碱失衡常见；④对于感染性ARDS，在有效控制感染下，使用肾上腺皮质激素可能改善预后。
Objective: To investigate the clinical significance of acute lung injury (ALI), acute respiratory distress syndrome (ARDS), systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) Efficacy of glucocorticoids. Methods: A retrospective study of clinical cases. RESULTS AND CONCLUSION: ① The mortality of ARDS patients was significantly higher than that of ALI patients (51.3% vs 20.5%), suggesting that it was meaningful to distinguish between ALI and ARDS. ② Infection and trauma were common factors in SIRS. The severity of MODS and the occurrence of ALI and ARDS prognosis; ③ ARDS patients with acid-base imbalance rate as high as 98.3%, and mixed acid-base imbalance is common; ④ Infectious ARDS, in the effective control of infection, the use of Cortisol may improve the prognosis.
