title: [Air contamination levels in operating rooms during surgery of total hip and total knee arthroplasty, hemiarthroplasty and osteosynthesis in the surgical center of a Brazilian hospital].
abstract: BACKGROUND
  The air contamination levels during orthopedic surgeries were evaluated.
  
  
  METHODS
  The air of operating rooms (ORs) was examined through exposure to microbiological plates placed near the surgical table for an hour.
  
  
  RESULTS
  values above that recommended (369 CFU/m³) for conventional ORs and ORs with ultraclean air were determined. Contamination was predominantly by Staphylococcus sp (86.9%). In all surgeries a high number of people were present inside the ORs and the doors were opened frequently.
  
  
  CONCLUSIONS
  The contamination levels are above the values accepted by regulatory agencies, representing risk for patients.
