ICU中肺源性及肺外源性急性呼吸窘迫综合征患者治疗和预后的临床观察

目的观察ICU中不同病因（肺源性或肺外源性）所致急性呼吸窘迫综合征（ARDS）患者的临床特点及治疗和预后的差异。方法收集北京友谊医院KU近2年来收治的ARDS患者共62例，进行回顾性分析和总结，分析不同病因ARDS患者的临床特点和预后指标的差别。结果两组总死亡率相近，但肺外源性ARDS患者预后，包括住ICU时间，呼吸机使用时间等指标明显好于肺源性ARDS患者，差异有显著性，死亡患者多为高龄；而肺源性ARDS患者住院时间长，呼吸机支持时间较长，治疗难度大。结论肺外源性或肺源性ARDS患者的临床特点及预后有较大差异，治疗应有所侧重。

Acute respiratory distress syndrome patients induced by pulmonary or extra-pulmonary causes in ICU:clinicat analysis of 62 cases

Objective To observe the difference in the clinical characteristics,treatment and prognosis between acute respiratory distress syndrome (ARDS) patients with different causes (pulmonary and extra-pulmonary). Methods Sixty-two ARDS patients in ICU of Beijing Friendship Hospital were involved in this study. The clinical characteristics and prognosis indexes were used to analyze the ARDS patients with pulmonary or extra-pulmonary causes. Results The mortality had no difference between the two groups. However the prognosis indexes including the time in ICU and the time using mechanical ventilation were better in extra-pulmonary group than those in the pulmonary group. The patients who died were mostly elderly patients. The length of hospital stay and time using mechanical ventilation were longer in pulmonary group than those in extra-pulmonary group. Conclusion There were obvious difference in clinical characteristics and prognosis between the patients with pulmonary and extra-pulmonary ARDS. Different treatment should be taken for different patients.
