摘　　要：目的:分析降钙素原危急值与病原学的关系,为急诊重症感染病人早期抗生素合理使用提供依据。方法:回顾分析我院急诊科2017年10月至2018年9月30日所有降钙素原危急值病人的临床资料,分析其病原学特点。结果:所查889例患者的降钙素原,共报87例危急值。同时送检血培养71例(81.6%)阳性率12例(19.7%),检出主要菌株为大肠埃希菌。结论:降钙素原危急值对临床有重要警示作用,此类病人血培养阳性率较高,首次抗生素使用要注意覆盖革兰氏阴性菌。Objective: To investigate correlation between critical value of procalcitonin and microbial infections in emergency patients. Methods: All the report result of critical value of procalcitonin in emergency department from October 1, 2017 to September 30, 2018 were reviewed. The correlation between critical value of procalcitonin and microbial infection was analyzed. Results: A total of 87 critical value of procalcitonin cases were included in all the 889 cases.Blood culture was tested in 71 cases at the same time. 12 patients were reported positive. The main strain was the escherichia coli. Conclusion: The emergence of critical values has a very important warning role on clinical. The positive rate of blood culture was higher in these patients, the first use of antibiotics should cover gram-negative bacteria.
