老年急性呼吸窘迫综合征肺内及肺外源性危险因素分析

目的:探讨老年急性呼吸窘迫综合征肺内及肺外源性危险因素。方法:回顾性分析130例老年ARDS患者,对其中的肺内及肺外源性危险因素进行分析。结果:肺内源性ARDS病因以误吸和肺炎为主,而肺外源性ARDS则以脓毒血症、大手术后等为主;在死亡上均与多器官功能障碍综合征、呼吸衰竭为主要因素,且两组死亡率接近。结论:在老年急性呼吸窘迫综合征中,肺外源性在器官功能衰竭和氧合指数上重于肺内源性,但是在其他因素和死亡结局上均无明显差异性。

Analysis of Pulmonary and Extra-Pulmonary Risk Factors of AcuteRespiratory Distress Syndrome for Elderly Patients*

Objective： To analyze and discuss the risk factors of acute respiratory distress syndrome both inter the pulmonary and extra pulmonary for the elder patients. Methods： A retrospective analysis was performed about the clinical data of 130 elderly patients for the risk factors of pulmonary disease. Results： Aspiration and pneumonia were the main causes of pulmonary acute respiratory distress syndrome. However, sepsis, major surgeries and so on were the main causes of extra-pulmonary acute respiratory distress syndrome. The death was mainly related with multiple organ dysfunction syndrome and respiratory failure, and the mortality rates of two groups were similar. Conclusion： The organ dysfunction and the oxygenation index of the extra-pulmonary group which was worse than that in the pulmonary group of the elder patients with the acute respiratory distress syndrome. However, there was no statistically differences of other factors between two groups.
