Abstract:
Objective To study the fatal risk factors to the patients with sepsis.Methods The data of 49 patients with sepsis were analyzed,who were consecutively admitted to intensive care unit(ICU)of Peking Union Medical College Hospital within six months.Patients' general states,clinical information,human leucocyte antigen-DR(HLA-DR)in blood monocytes and plasma level of diamine oxidase(DAO)were recorded.Simple logistic regression was done to analyze all the risk factors,and statistically significant variables were selected and used in multivariate and unconditioned Logistic regression analysis.The primary end point was hospital mortality.Results The subjects involved in present study were consisted of 49 patients with sepsis admitted to ICU of the Peking Union Medical College Hospital from Aug.2003 to Jan.2004,averagely aged 60.8?16.9 years;including 32 males(65.3%)and 17 females(34.7%);with APACHEⅡscores 18.6?8.0 and SOFA scores 5.9?3.8.Twenty-one out of the 49 patients(42.9%)were from non-operation department,and the other 28 patients(57.1%)were from operation department.ICU duration was 14.4?12.8 days;eighteen of the 49 septic patients died during hospitalization,with the 28-days mortality of 36.7%.Positive blood cultures(OR=5.237,95%CI 1.041~26.34,P=0.045),decreased platelet count and blood HLA-DR(OR=0.943,95%CI 0.901~0.98,P=0.01),and increased plasma levels of DAO(OR=2.235,95%CI 1.101~4.53,P=0.026)were obviously associated with mortality.The positive blood cultures,decreased blood HLA-DR and increased plasma levels of DAO were independent fatal risk factors for the patients with sepsis.Conclusions The positive blood cultures,decreased blood HLA-DR and increased plasma levels of DAO are high risk for the patients with sepsis at admission.
