RESUMO
OBJECTIVE To study the bacterial infections in ICU,pathogens distribution and their drug-resistance characteristics,so as to offer a reference to the prevention and control of hospital infection.METHODS Specimens from ICU from Jan 2003 to Dec 2004 were underwent a process of germ culture,identification and drug-sensitivity test.Germ culture-positive cases were confirmed by Diagnostic Standards of Hospital Infections.RESULTS Ninety three pathogens were identified from ICU in two years.Of all cases,63.44% were Gram-negative,30.1% were Gram-positive,and 9.68% were epiphyte.Among them,19.35% were Pseudomonas aeruginosa and it was the main one of Gram-negatives;9.68% were Staphylococcus aureus and it composed the most of Gram-positives;6.45% were epiphyte.Of all 93 pathogens,60 gained from respiratory tract,and 23 gained from urinary tract.CONCLUSIONS To emphasize on the strictly control of ICU,hospital infections and high risk disease,and to adopt certain preventive measures are the ways to control and decrease hospital infections.
