ABSTRACT
OBJECTIVE To investigate the bacteriologic feature and the spectrum of drug resistance in lung cancer patients who got nosocomial nonfermenters bacteria infection,and to conclude the experience and how to prevent and control the nosocomial infection.METHODS A rectrospective analysis of the composition of the pathogens,the feature of drug resistance and the prognosis of 109 lung cancer inpatients with nosocomial infection was made.RESULTS Nosocomial nonfermenters bacteria infections were most happened in hospital lung cancer patients.Main strains included Pseudomonas aeruginosa 55(49.5%),Acinetobacter baumannii 23(20.7%),and Stenotrophomonas maltophilia 8(7.2%).The sensitive rate of P.aeruginosa to imipenem was 100%,but to Cotrimoxazole,the resistant rate was 100%.The sensitive rate was relatively high to ticarcillin,piperacillin and their compounds.The antimicrobial resistance rate of A.baumannii was higher than P.aeruginosa.Stenotrophomonas were resistant to most antibiotics,and the resistance rate to imipenem was 100.0%.CONCLUSIONS The resistance rate of nosocomial nonfermenters bacteria infection is high.The treatment is difficult and the prognosis is bad.The mortality of multiple infection is high.
