血清PCT检测对急性胰腺炎合并感染患者的诊断价值分析

Diagnostic Value of Serum PCT in Patients with Acute Pancreatitis Complicated with Infection

目的:探讨血清降钙素原(PCT)检测对急性胰腺炎(AP)合并感染患者的诊断价值。方法:56例AP患者纳入观察组并进一步划分亚组,合并感染者22例,纳入感染组;未合并感染者34例,纳入非感染组。另选同期在我院接受体检的健康人员55例作为对照组,对观察组分别在入院第1d、7d及14d,对照组在入院当日抽取静脉血3ml检测血清PCT水平,对比各组不同时期的血清PCT含量水平,分析AP患者不同时期PCT水平与感染的相关性。结果:组间比较,第1、7及14d的PCT水平,观察组均分别显著高于对照组(P<0.05),感染组均显著高于非感染组(P<0.05)。组内比较,观察组、感染组和非感染组第7d的PCT水平显著高于第1d,第14d的PCT水平显著低于第1d与第7d(均P<0.05)。结论:根据Pearson法分析相关性可知,AP合并感染与第1d、7d及14d时患者的血清PCT水平均呈正相关。

Objective： To investigate the diagnostic value of serum（PCT） in patients with acute pancreatitis（AP） complicated with infection. Methods： 56 patients with AP were included in the observation group and 22 cases of patients with infection, cases were included in the infection group, and 34 cases without infection. Elect the same period in our hospital to undergo a medical health personnel 55 cases as the control group. In the observation group were in admission at 1D, 7d and 14 d, the control group in admission day venous blood 3ml serum PCT levels, measured at different period of serum PCT levels, analysis AP patients with PCT levels and the infection in different periods of correlation. Results：The levels of 14 d in group first, 7 and PCT were significantly higher than those in control group（P〈0.05）, and infection group were significantly higher than those in non infected group（P〈0.05）. The levels of PCT in the observation group, infection group and non infection group were significantly higher than those in 1D, and the level of PCT in 14 d was significantly lower than that in 1D and 7d（P〈0.05）. Conclusions： According to the analysis of Pearson, the serum levels of PCT were positively correlated with 1D, 7d and AP in patients with 14 d.
