目的探讨血流感染患者外周血血清降钙素原(PCT)定量检测的临床应用价值。方法 46例血流感染患者(感染组)与46例无血流感染者(对照组)作为研究对象,回顾性统计分析其血培养、PCT定量检测的结果。结果感染组患者PCT浓度>2 ng/ml的患者46例,PCT浓度≤2 ng/ml的患者0例;对照组患者PCT浓度>2 ng/ml的患者0例,PCT浓度≤2 ng/ml的患者为46例。血流感染患者血清PCT浓度明显高于对照组,差异具有统计学意义(P<0.05)。感染组患者PCT阳性46例(100.0%),血培养阳性38例(82.5%),PCT检测的阳性率高于血培养,差异具有统计学意义(P<0.05)。结论患者在血流感染早期PCT水平明显升高,PCT可作为血流感染的辅助诊断手段,值得推广。
Objective To investigate the clinical value of quantitative detection of serum procalcitonin (PCT) in peripheral blood of patients with bloodstream infection. Methods 46 cases of bloodstream infection (infection group) and 46 cases of non-bloodstream infection (control group) were studied. The results of blood culture and PCT quantitative analysis were retrospectively analyzed. Results In the infection group, 46 cases were treated with PCT concentration> 2 ng / ml, 0 cases with PCT concentration ≤ 2 ng / ml, 0 cases with PCT concentration> 2 ng / ml, PCT concentration ≤ 2 ng / ml Of the 46 patients. Serum PCT concentration in patients with bloodstream infection was significantly higher than that in the control group, the difference was statistically significant (P <0.05). In the infection group, 46 cases (100.0%) were positive for PCT, 38 cases (82.5%) were positive for blood culture. The positive rate of PCT test was higher than that of blood culture. The difference was statistically significant (P <0.05). Conclusions The PCT level in patients with early stage of bloodstream infection is significantly increased. PCT can be used as a supplementary diagnostic tool for bloodstream infection and is worthy of promotion.
