摘要
目的:探讨PCT水平对鉴别重症监护病房血流感染患者菌种的价值。方法:选择2011年3月-2014年1月本院ICU患者131例作为研究对象,按照其菌种将其分为G-组、G+组及真菌组,比较各组PCT水平差异,并根据其ROC曲线判断血清PCT的诊断性能。结果:三组血清PCT中位数水平差异具有统计学意义(P<0.05);血清PCT水平对G-菌与G+菌及真菌所致的血流感染鉴别诊断性能较高。结论:血清PCT水平对于鉴别G-菌与G+菌或真菌引起的血流感染有一定的临床鉴别价值,但是对于G+菌与真菌引起的感染鉴别意义尚不明确。
Objective： To investigate the value of calcitonin original level in identifying bacterial bloodstream infections of patients in intensive care unit. Method： 131 patients in ICU of our hospital from March 2011 to January 2014 were selected as the objects.They were divided into group G-, group G~ and group fungi according to different strains.Differences in PCT levels were compared among the three groups and diagnostic performance of serum PCT was determined according to its ROC curve. Result： Differences in median serum PCT levels of the three groups were statistically significant.Serum PCT level has a higher diagnostic capacity in differentiating bloodstream infections caused by G- bacteria and G^＋ bacteria or fungi.Conclusion： Serum PCT level plays a certain role in differentiating bloodstream infections caused by G- bacteria and G^＋ bacteria or fungi, but it plays an uncertain role in differentiating infections caused by G^＋ bacteria and fungi.
