RESUMEN
Objective To guide the treatment of acute exacerbation of chronic obstructive puhnonary diseases (AECO- PD) through studing the principally related factors of AECOPD.Methods 190 AECOPD patients were investigated through retrospective study.First,we studied the thirty-two possible factors with single-factor analysis,then procee- ded to perform multiple-factor analysis with Logistic regression among the factors which P value was below 0.2 in single -factor analysis,and analyzed the principally related factors with two-factor correlation.Results According to Mul- tiple-factor analysis with Logistic regression analysis,there were eight factors that showed significance,which were us- age of respiratory excitant,LBC,usage of antioxidant,heart failure,Cr,selection of antibiotics respectively,WBC and Hb.Correlative analysis of the principally related factors showed no correlation between WBC and LBC.Conclusion The principally related factors of AECOPD prognosis were their recited in results.
