Incidência de infecções associadas a Pseudomonas aeruginosa em pacientes internados em unidade de terapia intensiva

Abstract

Pseudomonas aeruginosa is a Gram-negative rod and the most important human pathogen in the genus Pseudomonas. First isolated in 1882 by Gessard, it was called Bacillus pyocyaneus. In the 1960s, there was concern in Brazil about maintaining control of hospital infections, beginning the first publications and reports on the subject. It is estimated that 5% to 15% of patients admitted to ICUs will acquire some kind of hospital infection and around 25% to 40% of them will receive antibiotics for treatment or prophylaxis of the infection. For the treatment of infections by this microorganism are penicillins, cephalosporins, carbapenems, monobactams, aminoglycosides and fluoroquinolones. According to reports found in articles the treatment with cephalosporins and carbapenems is 77% more effective than the class of aminoglycosides and fluoroquinolones that has the percentage of 42%. Objective and to evaluate the occurrence of nosocomial infections by multiresistant Pseudomonas in patients hospitalized in an Intensive Care Unit (ICU).
