Abstract：Objective:To explore the value of serum procalcitonin(PCT) detection and blood bacterial culture in the diagnosis of bacteremia. Method:Among the inpatients in our hospital from January 2015 to January 2016,a total of 60 patients with bacteremia were selected as group A,30 patients with tumor hyperthermia(group B) and 30 healthy subjects(group C) were enrolled in this study.The blood culture and serum levels of PCT in the three groups were analyzed retrospectively.Result:The PCT positive rate in group A was significantly higher than that in group B and C(P<0.05).When the bacteremia patients were with high fever,the PCT level of blood was increased in most patients,but the time of blood bacterial culture positive was later than that of serum PCT.72 h after the fever,the blood bacteria culture positive rate significantly reduced compared with 24 h,48 h after fever(P<0.05).The level of PCT in patients with infection control group was significantly lower than that in the not control group(P<0.05).Conclusion:Continuous blood PCT test is good for the development of bacteremia illness and the prognostic of treatment effect.Suspected bacteremia patients with serum PCT and blood bacterial culture combined detection can effectively shorten the diagnosis time and improve the accuracy of the diagnosis,it is very useful for the rational use of antibiotics and bacteremia treatment and prognosis.
