现今多重耐药菌的报道层出不穷,一个重要原因就是抗生素的滥用。在临床,感染的症状和体征不能准确说明病因,造成早期诊断的困难,而提高感染患者的生存率和减少抗生素滥用的关键在于准确地早期诊断。血清降钙素原(PCT)是一种能早期提示感染的生物标志物。对感染性疾病的预测,具有良好的特异度和灵敏度。与传统标志物相比,它能区分细菌感染和非细菌感染。总之,血清PCT能提示感染的类型和程度,指导抗生素的启用和终止,减少抗生素不合理应用。因此,血清PCT在感染中的应用有重要价值。
Today’s reports of multi-drug resistant bacteria after another, an important reason is the abuse of antibiotics. In clinic, the symptoms and signs of infection can not accurately explain the etiology, resulting in the difficulties of early diagnosis. The key to improve the survival rate of infected patients and reduce the abuse of antibiotics is accurate and early diagnosis. Serum procalcitonin (PCT) is a biomarker that prompts for early signs of infection. The prediction of infectious diseases, with good specificity and sensitivity. Compared with traditional markers, it can distinguish between bacterial and non-bacterial infections. In conclusion, serum PCT can indicate the type and extent of infection, guide the initiation and termination of antibiotics, and reduce the irrational use of antibiotics. Therefore, serum PCT in the application of infection has important value.
