title: Survey of infection in orthopedic postoperative and their causative agents: a prospective study.
abstract: OBJECTIVE
  to evaluate the cases of wound infections in orthopedic postoperative period.
  
  
  METHODS
  postoperative patients who developed infection during the period from November 2012 to November 2013 were studied. Secretions were collected during surgery using sterile swabs, and sent for microbiological analysis.
  
  
  RESULTS
  during the period analyzed, 38 surgical procedures progressed to infection. The type of surgery presenting the largest number of infections was osteosynthesis, in 36 (94.7%) patients. Among the materials used, 18 (36%) surgeries that used external fixator were infected, and 17 (34%) using plate. The species of bacteria that caused the largest number of infections were Staphylococcus aureus, infecting 16 (43.9%) patients, followed by Acinetobacter baumannii, which infected four (10.5%) patients. Regarding the resistance profile of Gram-positive strains to antibiotics, 100% of Staphylococcus aureus strains were susceptible to vancomycin and 31.3%, to ceftriaxone. As for the Gram-negative bacteria, 100% of Acinetobacter baumannii strains were resistant to ceftriaxone, gentamicin and imipenem.
  
  
  CONCLUSIONS
  infection control in the postoperative period is necessary, using antibiotics correctly and consciously, avoiding resistance of bacterial agents.
