摘　　要：目的探讨血清降钙素原(PCT)对腹腔感染的诊断意义。方法选取51例确诊腹腔感染及40例确诊呼吸系统感染无并发腹腔感染的ICU患者,于确诊感染并未使用抗菌药物治疗前取血,采用酶联免疫荧光法检测血清PCT水平,采用SPSS 17.0软件进行数据分析。结果腹腔感染患者PCT阳性率为78.4%,肺部感染患者阳性率为62.5%,PCT对腹腔、呼吸系统细菌感染诊断的阳性率虽差异无统计学意义,但腹腔感染组PCT水平显著高于肺部感染组(P<0.05),而两组间血清C反应蛋白水平、白细胞计数比较差异无统计学意义。结论 PCT可有效预测腹腔感染。OBJECTIVE To evaluate the value of serum procalcitonin in the diagnosis of abdominal infections.METHODS A total of 51 cases of patients confirmed with abdominal infections and 40 cases with single respiratory infections in ICU were selected,the blood was sampled before the diagnosis as infection and the treatment without using antibiotics,enzyme linked fluorescent assay（ELFA） was employed to measure the serum PCT.The results were statistically analyzed by using SPSS17.0.RESULTS The positive rate of PCT of the patients with abdominal infections was 78.4%,and the positive rate of the patients with pulmonary infections was 62.5%,although the difference in the positive rates of the abdominal infections and respiratory system infections diagnosed by PCT was not statistically significant,the PCT level of the patients with abdominal infection was significantly higher than those with pulmonary infections（P〈0.05）,the differences in the level of serum CRP and WBC counts were not statistically significant.CONCLUSION Serum PCT level may effectively predict the abdominal infections.
