ABSTRACT
En las fracturas abierta una de las complicaciones más temidas por los cirujanos ortopédicos es la infección de partes blandas y ósea. A pesar de múltiples investigaciones, las pautas de manejo terapéutico para las fracturas abiertas continúan en constante cambio. El objetivo principal de nuestro trabajo fue realizar una actualización sobre la prevención de la infección en las fracturas abiertas a través de una búsqueda bibliográfica poniendo especial énfasis en la utilidad de los cultivos (recuento microbiano) de heridas en el perioperatorio de estas fracturas.
In open fractures, one of the most feared complications by orthopedic surgeons is soft tissue and bone infection. Despite multiple investigations, therapeutic management guidelines for open fractures, is constantly changing. The main objective of our work was to make an update on the prevention of infection in open fractures through a bibliographic search, with special emphasis on the usefulness of cultures (microbial count) of wounds in the perioperative period of these fractures.

O principal objetivo do nosso trabalho foi atualizar a prevenção de infecção em fraturas expostas por meio de uma pesquisa bibliográfica, com ênfase especial na utilidade das culturas (contagem microbiana) de feridas no período perioperatório dessas fraturas.

PURPOSE: To help the empirical antibiotics selection in diabetic foot infection patients, we investigated prevalence of microorganisms and their antibiotics sensitivity results. MATERIALS AND METHODS: Patients who came to our clinics to treat diabetic foot infections with deep ulceration and were followed up more than 6 months until complete recovery were adopted. From March 2006 to June 2009, there were 140 patients who corresponded with such a inclusion criteria. Wound cultures were done by deep tissue or bone debris at first visit to our clinics. Microorganisms which was documented by wound culture and most susceptible antibiotics by minimum inhibitory concentrations were surveyed retrospectively. RESULTS: Microorganisms were confirmed in 113 cases (80.7%). In the other 27 cases (19.3%), there were no cultured microorganisms. In bacterial growth group, there were 72 cases (63.7%) of gram-positive bacteria and 41 cases (36.3%) of gramnegative bacteria. All of them were aerobic microorganisms and there were no anaerobic microorganisms. Methicillin-sensitive staphylococcus aureus was the most common pathogen and accounted for 35 cases (31.0%). As other common pathogens, there were Enterobacter cloacae (11 cases, 9.7%), pseudomonas aeruginosa (10 cases, 8.8%), Methicillin-resistant staphylococcus aureus (10 cases, 8.8%) and enterococcus faecalis (6 cases, 5.3%), and so on. Common susceptible antibiotics in gram positive microorganism were vancomycin (60 cases, 83.3%), teicoplanin (60 cases, 83.3%), nitrofurantoin (60 cases, 83.3%) and ciprofloxacin (53 cases, 73.6%). In gram negative ones, common susceptible antibiotics were imipenem (35 cases, 85.3%), piperacillin/tazobactam (33 cases, 80.5%) and gentamicin (31 cases, 75.6%). CONCLUSION: Methicillin-sensitive Staphylococcus aureus in gram positive and enterobacter cloacae in gram negative was the most common pathogen in each group. Ciprofloxacin and gentamicin might be adaptable as a first-line empirical antibiotics in infected diabetic foot patients.
