【摘要】：目的探讨降钙素原(PCT)区分ICU病房血培养阳性患者主要致病菌的意义。方法收集血培养阳性(单一菌)患者113例作为研究对象,检测其血清PCT水平,并分析革兰阴性(G~-)菌、革兰阳性(G~+)菌和真菌与PCT水平的相关性。结果 113例血培养阳性标本中,G~-菌69例(61.06%)、G~+菌36例(31.86%)、真菌8例(7.08%)。G~-菌、G~+菌及真菌感染患者血清PCT分组情况差异有统计学意义(χ~2=33.534,P0.01)。G~-菌、G~+菌及真菌感染患者血清PCT检测阳性率差异有统计学意义(χ~2=22.157,P0.01)。在G~-杆菌中,大肠埃希菌PCT值中位数高于鲍曼不动杆菌;在G~+菌中,31.25%凝固酶阴性葡萄球菌PCT值为阴性。结论 ICU病房血培养阳性以G~-杆菌为主,PCT值用于区分不同病原菌感染有一定意义。
[Abstract]:Objective to investigate the significance of procalcitonin (PCT) in distinguishing the main pathogenic bacteria in patients with positive blood culture in ICU ward. Methods the serum PCT levels of 113 patients with positive blood culture (single bacteria) were measured, and the correlation between Gram-negative bacteria, Gram-positive bacteria and fungi and PCT levels was analyzed. Results there were 69 cases (61.06%) of G bacteria, 36 cases (31.86%) of G bacteria and 8 cases (7.08%) of fungi. There was significant difference in serum PCT levels among G ~-bacteria, G ~ bacteria and fungal infection patients (蠂 ~ 2 鈮，
