摘要
目的研究降钙素原(PCT)与乳酸对老年社区获得性肺炎患者的病情和预后的评估作用。方法 118例老年社区获得性肺炎患者,入院后给予PCT、乳酸等检查,并给予肺炎严重指数(PSI)评分。分别比较重症与非重症肺炎、死亡组和存活组PCT、乳酸和PSI的区别;分析PCT、乳酸与PSI的相关性。结果重症肺炎患者乳酸、PCT和PSI评分均大于非重症患者,死亡组乳酸、PCT和PSI评分均大于存活组(P<0.05);乳酸、PCT与PSI评分呈正相关(r=0.63,0.65,P<0.05)。结论 PCT和乳酸对老年社区获得性肺炎患者的预后和病情有评估作用,PCT和乳酸升高提示患者预后差。
Objective To evaluate the function of lactate and procalcitonin （PCT） in the prognosis of elderly patients with com- munity acquired pneumonia （CAP）. Methods 118 cases of elderly CAP patients were selected to examine their PCT, lactate and pneu- monia severity index （PSI） score. PCT and PSI scores were compared between the death group and the survival group, as well as the se- vere pneumonia group and non-severe pneumonia group. The relationship between the content of lactate and PCT and PSI score was ana- lyzed. Results The levels of PCT and lactate and PSI scores were higher in the severe pneumonia group and the death group than in the non-severe pneumonia group and the survival group （ P 〈 0.05 ）. There was a positive correlation between PSI scores and the levels of lac- tate and PCT （ r = 0.63, 0. 65, P 〈 0. 05 ）. Conclusion The levels of lactate and PCT have certain prognostic evaluation function for elderly patients with CAP, and the high levels of lactate and PCT suggest a poor prognosis.
