Clinical analysis of nosocomial infection in senium patients with severe breathing diseases

Objective To observe the pathogen distribution characteristics of nosocomial infection in older patients with severe breathing diseases,and hence to offer reference for prevention and treatment.Methods The clinical data were retrospectively analysed in 69 older patients with severe breathing diseases hospitalized from May 2010 to May 2011.Results 125 strains of pathogen were isolated from 426 specimens in the 69 patients,including pathogenic bacteria G-accounting for 63.6%,G+ accounting for 21.1%,fungal accounting for 15.3%;G-Bacilli were mainly bowman’s acinetobacter,G+ coccus showed more staphylococcus aureus,and fungi with white candida mycoderma;Bacteria originated from respiratory tract,urinary tract,and enteron.Conclusions The pathogen of nosocomial infection in older patients with severe breathing diseases were mainly G-Bacilli and mainly existed in respiratory.
