Abstrakt: In this prospective study, we aimed to investigate whether surgical gowns become contaminated during surgery. Samples from the gowns of five surgeons during 19 surgeries were collected using sterile swabs in circular standard delimited areas on both wrists and the mid-chest at three time-points: immediately before surgical incision (t=0), 30 min (t=30), and 60 min (t=60) later. Additionally, at t=0 and t=60, three settle plates of plate count agar were positioned at 1.5 m from the ground and remained open for 20 min. The operating room temperature and relative humidity were monitored. The swabs were cultivated and incubated, and colony-forming units per gram (CFU/g) counts were measured. The CFU/g counts for bacteria or fungi did not differ among the three sampling sites. The surgeons' lateral dominance in manual dexterity did not influence the gowns' contamination. There were significant variations in the temperature and relative humidity over time, but not in the CFU/g counts. In conclusion, during the first hour of surgery, surgical gowns did not become a source of contamination and are an effective barrier against bacterial and fungal contamination even under non-standard surgical environmental conditions.
