Abstract:
OBJECTIVE To investigate the associated risk factors for the infected patients in respiratory intensive care unit(RICU) and to study the resistance of isolates.METHODS To study the bacterial spectrum and drug resistance test of all the patients with hospital acquired infection from Jan to Dec 2005.Identification and antimicrobial susceptibility were determined with the methods of API and K-B,respectively.RESULTS A total of 265 strains were isolated from 117 patients,the rate of isolation of Gram-negatives was the highest(74.3%),the species were predominated by Pseudomonas aeruginosa,Acinetobacter baumannii and Klebsiella pneumoniae,the rates of isolates were 28.68%,23.02% and 5.66%,respectively.The predominated species of Gram-positives was Staphylococcus aureus.Gram-negative bacilli were susceptible to imipenem and meropenem,there were not vancomycin-resistant strains.CONCLUSIONS It is important to realize the associated risk factors of infected patients in RICU and to promote the rational use of antimicrobial agents.
