ABSTRACT

In spite of being very well-known the effect that it has more than enough the patient, the society and the economy has the Nosocomial Infection (IN), these still continue even taking place in centers where control programs and very efficient surveillance exist. These infections commit the state of the patients and they rebound negatively in the success of the treatments applied in the instances of health. In the Hospital “Dr. Miguel Enríquez” the team in charge of the epidemic surveillance and the Laboratory of Microbiology, they work together with the objective of achieving the decrease of the incidence of these infections. With the data obtained on those IN having happened in the year 2002, it was carried out a retrospective descriptive study that allowed us to know like it was the behavior of the IN in this center during that year. They were part of this study 643 patients infected in this period and 779 samples processed for the determination of the microorganisms responsible for these infectious processes. The rate of IN global it was of 4,5% and 78,7% of the infected patients it had study, being obtained 79% of positive of the processed samples. The infections of the skin and/or mucous and wounded surgical they were those more frequently infected in this year, and in them the biggest positive percentages were obtained (30,1% and 21,2% respectively). Pseudomonas aeruginosa (22,2%), Staphylococcus aureus (18,5%) and Staphylococcus spp negative coagulase (15%) they were the isolated bacterial species in the processed samples. Alone 5 stumps of Candida spp were isolated. Ciprofloxacine, ceftriaxone and amikacine (10,7%, 12,6% and 29,8% respectively), they were the antibiotics in those that smaller resistance was obtained “in vitro” of the isolated bacteria. In general sense an antibiotic and alone high resistance was observed in the previously signal antibiotics resistance percentages they were obtained below 30%.
