Chronic Obstructive Pulmonary Disease Patients with Gram-negative Bacteria Nosocomial Pneumonia / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the organism and drug resistance in chronic obstructive pulmonary disease(COPD) patients with Gram-negative bacteria(GNB) nosocomial pneumonia,in order to provide the index to clinician. METHODS The bacteria were tested by Micro WalkAway-40 which made in the USA,the susceptibility test was carried by disk diffusion test. RESULTS The rates of Klebsiella pneumoniae and Pseudomonas aeruginosa among all bacteria were higher,which were 26.8% and 26.2%,respectively;the organisms were almost drug resistant,which were more sensitive to imipenem,amikacin and ceftazidime,and more resistant to other drugs. CONCLUSIONS The hospital should make precautions,diagnose in time,and use antibiotic reasonably.
