Procalcitonin-guided antibiotic treatment group
Standard antibiotic therapy group
Patients were divided into 2 subgroups: No infection group (including patients with procalcitonin<0.1 ng/ml at enrollment, and patients with 0.1 ng/ml ≤procalcitonin ≤0.25 ng/ml at enrollment who are with stable respiratory and hemodynamics, and without serious complications) : the group is not given the application of antibiotics. Infection group (including patients with procalcitonin>0.25 ng/ml at the time of enrollment, and patients with 0.1 ng/ml ≤ procalcitonin≤0.25 ng/ml at enrollment who have severe disease, unstable hemodynamics, and severe complications or intensive care unit treatment): the group is given the application of antibiotics. According to the guidelines for severe sepsis / septic shock treatment, the standard for discontinuation of antimicrobial agents: If the procalcitonin level falls below <0.1 ng/ml or more than 80%, compared with the baseline before enrollment, it is recommended to discontinue the antimicrobial agent.
The application of antibiotics is given to patiens according to the doctor's experience.
