Application of procalcitonin and CRP as prognostic markers in surgery infections

Objective To evaluate the value of procalcitonin and CRP as prognostic markers in surgery infections.Methods 72 patients who were treated surgically in our hospital from 2007 to 2008.All the patents were divided into 3 groups:non-infection,intensive infection and partially infection respectively.Serum procalcitonin and CRP levels were measured in the first 3 days or before the using of antibiotics.Results Procalcitonin and CRP levels were significantly higher than that of the other two groups(P0.05),especially the procalcitonin level.Taking procalcitonin≥2μg/L as the diagnostic standards for intensive infection,its sensitivity and specifity are higher than CRP.Conclusion Compared to CRP,Procalcitonin is a marker for the diagnosis of bacterial infections in surgery,especially for the early diagnosis.
