Laminar airflow versus turbulent airflow in simulated total hip arthroplasty: measurements of colony-forming units, particles, and energy consumption

SummaryBackground The optimal type of ventilation in operating theatres for joint arthroplasty has been debated decades. Recently, the World Health Organization changed its recommendations based on articles that have since criticized. economic and environmental impact is also currently an important research topic but not well investigated. Aim To compare how large, high-volume, laminar airflow (LAF) turbulent (TAF) systems perform during standardized simulated total hip (THA), as they pertain to colony-forming units (cfu), particle counts, energy consumption. Methods Two identical were used THA. only difference was one equipped with LAF other TAF. Cfu particles collected from key points theatre, measured each simulation. Thirty-two simulations done total. Findings had significantly reduced cfu count when compared TAF, at both 100% 50% air influx. Furthermore, it shown lowering influx by did affect or particles, although reducing fresh lowered Most TAF meet cleanroom requirements. Conclusion lower It possible reduce 50%, consumption, while still maintaining counts below ISO classification threshold required THA surgery.
