Abstract:
Objective To explore the clinical significance of procalcitonin(PCT) in the diagnosis of bacterial infection in burn pa‐tients .Methods Among 169 burn patients ,96 cases were bacterial infection confirmed by blood ,secretion and puncture fluid culture and 73 cases were non‐bacterial infection .PCT ,WBC and hyper sensitive C reactive protein (hs‐CRP) were detected .The diagnostic values in bacterial infection were compared among these 3 indexes and the relationship between PCT level and burn degree was fur‐ther studied .Results Serum PCT ,WBC and hs‐CRP levels in the bacteria infection group were obviously higher than those in the non‐bacterial infection group(P<0 .05);the sensitivity ,specificity ,positive predictive value and negative predictive value of PCT were 90 .63% ,89 .04% ,91 .58% and 87 .84% respectively ,which indicated that PCT had higher diagnostic value than WBC and hs‐CRP .The PCT level was positively correlated with the degree of burn degree .Conclusion Serum PCT ,WBC and hs‐CRP in the burn patients with bacteria infection are greatly increased .PCT as the marker of bacterial infection has the higher sensitivity and specificity than WBC and hs‐CRP in the diagnosis of bacteria infection .
