早期血乳酸监测在老年社区获得性肺炎中的临床价值

目的研究早期乳酸和乳酸清除率监测对老年社区获得性肺炎（CAP）患者预后的评估价值。方法收集我院急诊科入院时血乳酸升高老年CAP患者55例,根据预后分为死亡组和存活组,比较两组患者的乳酸水平、6 h和24 h乳酸清除率、机械通气、急性生理学及慢性健康状况评价Ⅱ（acute physiology and chronic health evaluationⅡ,APACHEⅡ）评分等指标的区别;把55例乳酸升高CAP患者根据乳酸清除率≥10%和〈10%分为两组,比较两组病死率和APACHEⅡ评分等指标的区别。结果死亡组与存活组患者比较,在入院乳酸值、6 h和24 h乳酸清除率有显著性差异（P〈0.05）;6 h乳酸清除率≤10%的老年CAP患者病死率明显大于乳酸清除率≥10%患者（P〈0.01）。结论入院时乳酸值和6 h乳酸清除率是评价老年CAP患者预后的良好指标。6 h清除率≤10%时提示患者预后较差。

The clinical value of early blood lactate monitoring in the elderly patients with community-acquired pneumonia

Objective To study the clinical value of early lactic acid and lactate clearance rate in evaluating the prognosis of elderly patients with community-acquired pneumonia(CAP).MethodsThe Clinical data of 55 elderly CAP patients with elevated blood lactic acid were collected at Department of Emergency,XuanWu Hospital of Capital University of Medical Sciences,According to the prognosis,the patients were divided into death group and survival group.the difference of lactate levels,6h and 24 h lactate clearance rat...
