Influence of surgical team activity on airborne bacterial distribution in the operating room with a mixing ventilation system: a case study at St. Olavs Hospital
2021, Journal of Hospital InfectionCitation Excerpt :A high volume of staff movement and activities could play a role in higher risk of surgical site infections (SSIs) [6]. Generally, staff movement can increase the colony forming unit (cfu) level by three means: (1) clothes rub against the skin, leading to increased shedding [7]; (2) a pumping effect inside clothes that creates air streams that can transport skin scales into the OR air through pores in the fabric structure or from openings (such as the wrists, neck, ankles and the waist) [8]; and (3) movement may cause settled particles on the floor and other surfaces to be re-suspended into the air [7]. A number of studies have explored influencing factors using various experimental methods.
Ventilation design conditions associated with airborne bacteria levels within the wound area during surgical procedures: a systematic review
2021, Journal of Hospital InfectionDo 'Surgical Helmet Systems' or 'Body Exhaust Suits' Affect Contamination and Deep Infection Rates in Arthroplasty? A Systematic Review
2016, Journal of ArthroplastyCitation Excerpt :Operating room staff are thought to be the source of air and wound contamination in up to 98% of cases [2,3]; an individual can shed between 5000 and 55000 particles per minute and physical activity of the staff is known to affect the circulation of the shed particles [29]. A fundamental design principle of BES is high flow extraction to remove these particles, and extraction rates of up to 400 L/min have been recommended [30]. Whilst some early SHS designs included portable exhaust outlets [31,32], SHS primarily use air intake fans to provide adequate airflow for surgeon comfort.
Preventing surgical-site infections: Measures other than antibiotics
2015, Orthopaedics and Traumatology: Surgery and ResearchCitation Excerpt :The only benefit from the suit was improved protection of the staff from splashes of blood or other body fluids. Similarly, filtered exhaust suits incorporating a self-contained ventilation system were not more effective than conventional surgical masks [22,26]. Furthermore, Shaw et al. suggested that the increased temperature around the face might promote bacterial growth and that the increased pressure within the suit might increase the dissemination of bacteria if the seal between the helmet and gown was not fully effective [27].
