Continuous Detection of Procalcitonin and Blood Culture in the United Diagnosis of Bacteremia

Objective To discuss the value of continuous detection of procalcitonin and blood culture in the united diagnosis of bacteremia.Methods 76 patients with bacteremia(bacteremia group),32 patients with tumor fever(tumor group) and 20 healthy subjects(healthy control group) were detected for the serum levels of PCT in the first visit.Bacteremia group received blood culture every 24 h and detected for both indicators.The levels of PCT in the 3 groups were compared,the diagnosis value of continuous detections was analyzed,and the results of PCT in bacteremia group were observed before and after antibiotics treatment.Results Positive rate of PCT in the 3 groups were 82.89%,15.62%,and 0 at the first test,and there were significant differences between the 3 groups(P0.01);The positive rate of blood culture in bacteremia group was 22.36% at the first test,and it increased with the increase of blood culture;the level of PCT decreased when bacteremia was controlled.Conclusion Continuous detections of procalcitonin and blood culture can not only increase the diagnosis rate of bacteremia,but also can be used in the prognosis of bacteremia.Clinicians should choose the best time of blood culture to improve the diagnosis rate of bacteremia according to the the length of heat time.
