目的:分析降钙素原对重症肺炎患者的临床应用价值。方法:随机抽取我院2013年1月-2014年1月90例重症肺炎患者作为观察组研究对象,同时选取90例同期治疗的轻型肺炎患者作为对照组研究对象,两组均与血常规检查,静脉血采集,比较两组患者的降钙素原(PCT)、白细胞计数(WBC)、C反应蛋白(CRP)及体温指标。同时将观察组以PCT水平予以分级,主要包括A组(≥0.5μg/L)、B组(≥0.5~2.0μg/L)、C组(≥2.0~10.0μg/L)、D组(≥10.0μg/L),研究分析各组呼吸机应用状况、病死情况和抗生素使用时间。结果:观察组患者的PCT、CRP水平较对照组相比有了明显上升,两组比较,差异具有统计学意义(P<0.05);PCT水平与重症肺炎患者的抗生素使用时间、呼吸机应用次数存在正相关。结论:降钙素原有显著的重症肺炎诊断效果,能为肺炎患者病情的诊断与评估提供有力依据。
Objective: To analyze the clinical value of procalcitonin in patients with severe pneumonia. Methods: Ninety patients with severe pneumonia in our hospital from January 2013 to January 2014 were randomly selected as the study group. At the same time, 90 patients with mild pneumonia treated at the same period were selected as the control group. Both groups were compared with the routine blood tests, Venous blood was collected for comparison of procalcitonin (PCT), white blood cell count (WBC), C-reactive protein (CRP) and body temperature index in two groups. At the same time, the observation group was graded according to the level of PCT, including A group (≥0.5μg / L), B group (≥0.5 ~ 2.0μg / L), C group (≥2.0-10.0μg / L) 10.0μg / L), study the application of ventilator in each group, the case of death and antibiotic use time. Results: The levels of PCT and CRP in the observation group were significantly higher than those in the control group, the difference was statistically significant (P <0.05). The levels of PCT and the duration of antibiotics in patients with severe pneumonia, the number of ventilator application There is a positive correlation. Conclusion: The original calcitonin significant diagnosis of severe pneumonia can provide a strong basis for the diagnosis and evaluation of the disease in patients with pneumonia.
