[目的]评价降钙素原对为重症患者感染的早期诊断意义。[方法]选择78例危重症患者,分为感染组和非感染组,两组患者均采用半定量免疫色谱法测定PCT值,以PCT测定值﹥2ng/ml为阳性值。[结果]感染组40例,阳性例数28例(70.00%);非感染组38例,阳性例数7例(18.42%),两组差异有统计学意义(χ2=20.9578,P﹤0.001)。[结论]在危重症患者中测定血清PCT值有助于判断早期是否存在感染及感染的严重程度。
[Objective] To evaluate the early diagnostic significance of procalcitonin for severe infections in patients. [Method] Seventy-eight critically ill patients were selected and divided into infection group and non-infection group. The PCT values were determined by semi-quantitative immunochromatography in both groups. The PCT values> 2ng / ml were positive. [Results] There were 40 cases in the infection group and 28 cases in the positive group (70.00%). There were 38 cases in the non-infected group and 7 cases in the positive group (18.42%), the difference was statistically significant (χ2 = 20.9578, P <0.001) . [Conclusion] The determination of serum PCT value in critically ill patients can help to judge the early infection and the severity of infection.
