Abstract:
Objective To investigate the clinical significance of procalcitonin and acute phase protein on pulmonary infection of patients with craniocerebral injury .Methods Totally 63 cases of severe craniocerebral injury patients treated in our hospital from January 2014 to October 2014 were divided into infection group(n=37) and non infection group(n=26) .Peripheral blood speci‐mens was collected within one hour patients′admission of ICU ,the observation index were:T(℃) ,WBC(× 109/L) ,PCT and CRP . Results The level of PCT and CRP of infection group in each period were higher than non infected group (P<0 .05);the diagnos‐tic sensitivity of PCT ,CRP and PCT combined CRP was 78% ,81% and 81% ,respectively ;the diagnostic specificity of PCT com‐bined CRP was 77% ,which was significantly higher than PCT (69% ) and CRP(15% ) .Conclusion The positive rate and specifici‐ty of PCT combined with CRP is high ,thus it could be used as specific and sensitive indexes for early secondary pulmonary infection in head injury patients .
