Background: Filtered-exhaust helmet systems are commonplace during total joint arthroplasty, but their ability to limit intraoperative contamination has been questioned. We hypothesized that activation of the airflow system after complete gowning would lead to decreased contamination of the surgical environment.
Methods: Using a fluorescent particle model, the maximal particle spread from a filtered-exhaust helmet and contamination of the surgical environment based on timing of airflow activation through simulated surgical gowning procedures were evaluated.
Results: Helmet airflow analysis revealed particle spread greater than 5 feet in all trials. Activation before gowning resulted in a significantly greater contamination in the control group compared with the experimental group (P = .014).
Conclusions: We recommend complete surgical gowning before activation of the airflow system.

Purpose: To assess bacterial contamination of 20 eyeglasses from surgeons.
Methods: 40 samples were taken from the nose pad (n=20) and earpiece (n=20) of 20 eyeglasses from orthopaedic surgeons using a sterile swab stick soaked in sterile distilled water. Swabs were incubated and inoculated onto 3 plates: Staphylococcus/Streptococcus agar plate, Mannitol salt plate, and Chromogenic agar plate.

Filtered exhaust helmets (space suits) have been reported as efficacious in decreasing wound infections following joint arthroplasty procedures; however, strict experimental control of the many variables related to the incidence of clinical infection has been lacking in these studies, making support of such conclusions difficult. Any potential benefit of filtered exhaust helmets in the control of infection rates can be logically assigned to the reduction of airborne bacterial counts within the operating room. A study was done using the Steri-Shield helmet (Bio-Medical Devices, Irvine, CA) to define its efficacy in limiting airborne bacterial contaminates during total joint arthroplasty.
