目的分析降钙素原(PCT)与内毒素(ET)在腹部创伤术后患者肺部感染中的诊断价值,为临床诊断提供依据。方法选取2015年1-12月医院收治的腹部创伤术后肺部感染患者88例,根据感染的病原菌不同将其分组,细菌组30例与非细菌组58例;对两组患者的血清PCT与ET水平进行检测,并对其进行统计分析。结果在PCT阳性率与ET阳性率方面,细菌组与非细菌组比较均明显升高,差异均具有统计学意义(P<0.05);PCT在腹部创伤术后患者肺部感染中的诊断敏感度与特异度分别为93.3%、94.8%,ET诊断敏感度与特异度分别为66.7%、69.0%,两者比较差异有统计学意义(P<0.05)。结论降钙素原与内毒素的检测对腹部创伤术后患者是否并发肺部感染具有较为显著的临床价值,且PCT的诊断价值高于ET,可作为优选诊断指标。
Objective To analyze the diagnostic value of procalcitonin (PCT) and endotoxin (ET) in patients with lung infection after abdominal trauma and provide the basis for clinical diagnosis. Methods From January to December 2015, 88 patients with post-traumatic pulmonary infection in our hospital were enrolled. According to the different pathogenic bacteria, 88 patients were divided into bacteria group and non-bacteria group, 58 patients. The serum PCT ET levels were detected, and its statistical analysis. Results The positive rates of PCT and ET were significantly higher in both bacterial and non-bacterial groups (P <0.05). The diagnostic sensitivity of PCT in patients with lung infection after abdominal trauma And specificity of 93.3% and 94.8% respectively, the diagnostic sensitivity and specificity of ET were 66.7% and 69.0%, respectively, with significant difference (P <0.05). Conclusion The detection of procalcitonin and endotoxin have significant clinical value in patients with pulmonary infection after abdominal trauma, and the diagnostic value of PCT is higher than that of ET, which can be used as the optimal diagnostic index.
