摘要 目的探讨老年肺炎患者血清C-反应蛋白(CRP)、D-二聚体、乳酸(LA)水平及其临床意义。方法选择老年肺炎患者90例作为肺炎组,同期体检的健康者90例作为对照组。90例肺炎患者根据是否死亡,分为死亡组和存活组。测定肺炎组和对照组患者的血清、D-二聚体、LA水平,计算肺炎患者血清乳酸清除率,根据血清乳酸清除率将肺炎患者分为高乳酸清除率组和低乳酸清除率组,比较肺炎组和对照组患者血清C-反应蛋白、D-二聚体和LA水平,存活组和死亡组血清CRP、D-二聚体和LA水平,存活组和死亡组乳酸清除率,高乳酸清除率组和低乳酸清除率组患者死亡率。结果老年肺炎组患者血清C-反应蛋白、D-二聚体和乳酸水平均明显高于对照组患者(P<0.05);老年肺炎死亡组患者血清CRP、D-二聚体和LA水平均明显高于存活组患者(P<0.05);老年肺炎死亡组患者血清乳酸清除率明显低于存活组患者(P<0.05);老年肺炎高乳酸清除率组患者的死亡率明显低于低乳酸清除率组患者(P<0.05)。结论老年肺炎患者的血清CRP、D-二聚体和LA水平升高,老年肺炎死亡患者的CRP、D-二聚体和LA水平高,低乳酸清除率患者的死亡率比较高。
