摘　　要：Objective To investigate the baseline levels of microorganisms’growth on the hands of anesthesiologists and in the anesthesia environment at a cancer hospital.Methods This study performed in nine operating rooms and among 25 anesthesiologists at a cancer hospital.Sampling of the hands of anesthesiologists and the anesthesia environment was performed at a ready-to-use operating room before patient contact began and after decontamination.Results Microorganisms’growth results showed that 20%(5/25)of anesthesiologists’hands carried microorganisms(>10 CFU/cm^(2))before patient contact began.Female anesthesiologists performed hand hygiene better than did their male counterparts,with fewer CFUs(P=0.0069)and fewer species(P=0.0202).Our study also found that 55.6%(5/9)of ready-to-use operating rooms carried microorganisms(>5 CFU/cm^(2)).Microorganisms regrowth began quickly(1 hour)after disinfection,and increased gradually over time,reaching the threshold at 4 hours after disinfection.Staphylococcus aureus was isolated from the hands of 20%(5/25)of anesthesiologists and 33.3%(3/9)of operating rooms.Conclusion Our study indicates that male anesthesiologists need to pay more attention to the standard operating procedures and effect evaluation of hand hygiene,daily cleaning rate of the operating room may be insufficient,and we would suggest that there should be a repeat cleaning every four hours.
