摘要 目的探讨重症细菌性感染患者血清降钙素原(PCT)检测的临床意义。方法选取细菌性感染重症患者70例(细菌感染组),非细菌感染重症患者60例(非细菌感染组),健康体检者60例(对照组),对三组患者血清PCT进行检测分析。结果对照组PCT(3.28±1.37)μg/L明显低于重症患者的(16.84±1.86)μg/L(t=47.74,P〈0.05);细菌感染组PCT〉10μg/L者占27.14%,明显高于非细菌感染组的6.67%,且细菌感染组APACHE-lI及APACHE—m评分分别为(16.57±6.01)分、(63.14±20.08)分,明显高于对照组的(12.53±4.57)分、(45.07±26.17)分(t=31.13、30.42,均P〈0.05)。随着血清降钙素原水平的升高,对重症患者感染诊断的特异性增高,但敏感性降低。结论通过监测血清降钙素原对重症细菌性感染患者进行诊断,有较高的敏感性及特异性,且操作简单。
