ABSTRACT
Objective To study the serum procalcitonin (PCT)in patients with sepsis clinical application value,for the hospi-tal,infection control,to provide a scientific basis for reasonable Shaanxi General of antibiotics.Methods Retrospective anal-ysis of Shaanxi General hospital of CARF in 2011 May~2013 May 201 cases of patients with ICU,According to the severi-ty of infection were divided into 4 groups(SIRS)63 cases,(Sepsis)40 cases,(Severe sepsis)70 cases,(Septic shock)19 ca-ses,Dynamic analysis of ICU monitoring in 1,3,5,7,10,14,17 days each in the blood in patients with PCT,hs-CRP and WBC levels and blood culture,and PCT on the sensitivity,sepsis diagnostic specificity,positive predictive value,and negative predictive value,diagnostic accordance rate.Results PCT levels of SIRS and Sepsis (1.92 ng/ml)(10.8 ng/ml)group,the Severe Sepsis (24.0 ng/ml),and Septic shock compared (34.0 ng/ml)group,the difference was statistically significant (q1=13.8,q2=15.6,q3=17.9,P0.05),PCT levels and the severity of sepsis in positive correlation (r=0.781).The positive rate of blood culture in 26.6%,and PCT the on diagnosis of sepsis sensitivity,specificity,positive predictive value (PP),negative predictive value (NPV)were 87.2%,85.4%,78.9% and 89.3%,respectively,for sepsis diagnosis coincidence rate 85%, the increase of PCT level(≥ 1 ng/ml)was anindependent index 28 natural deposit rate.Conclusion Compared with PCT hs-CRP and WBC could better evaluate the severity of sepsis,and dynamic j udgment of sepsis disease prognosis was more sensitive.Joint detection with blood culture could improve the of accuracy differential diagnosis of sepsis,and to guide clinical rational application of antibiotics.The change of concentration of PCT daily can help predict mortality risk in patients with sepsis in ICU of the hospital,reduce complications and reduce mortality.
