目的 :探讨急性肺损伤 (ALI)在产科危重急症合并全身炎症反应综合征 (SIRS)中的临床意义。方法 :将近年收治的 7例产科危重急症的临床诊疗及预后作比较。结果 :全身炎症反应综合征常贯穿产科危重急症的始终 ,急性肺损伤作为全身炎症反应综合征的临床表现 ,出现最早、发生率也最高。结论 :急性肺损伤的早期发现、诊断及治疗 ,对降低死亡率及改善预后极为重要。 Objective: To investigate the clinical significance of acute lung injury (ALI) in obstetric critical illness complicated with systemic inflammatory response syndrome (SIRS). Methods: The clinical treatment and prognosis of 7 critically ill obstetric patients admitted in recent years were compared. Results: The systemic inflammatory response syndrome often runs through the critical stage of obstetrics. Acute lung injury is the clinical manifestation of systemic inflammatory response syndrome, with the earliest and the highest incidence. Conclusion: Early detection, diagnosis and treatment of acute lung injury are very important in reducing mortality and improving prognosis.
