Reduction in Airborne Bacterial Levels in Operating Theatre Using Supplemental Ultraclean Air System

Study Director
W.R. Walsh, Ph.D.

Study Design

The study was designed to test the efficacy of the supplemental ultraclean air system (SUCAS, Illuvia 500UV) developed by AEROBIOTIX on airborne bacterial levels during arthroplasty. Study was conducted in the community tertiary care hospital in New South Wales, Australia. Rooms were standard positive pressure. Two operating theatres were utilized. The Operating Theatre 1 had AEROBIOTIX Illuvia system and BIOTRAK particle counter present. The operating Theatre 3 served as the
control. The same number and type of procedures were performed in both theatres (Case 1- total knee replacement; Case 2 total hip replacement; Case 3- total knee replacement). Base levels of bacterial and fungi were sampled at 4:30 am, at least 2 hours prior to the start of surgical procedures.

Results

In order to test the efficacy of SUCAS system in reducing airborne bioburden two different arthroplasty operating rooms were selected for evaluation. The air from both ORs was sampled continuously over the span of three arthroplasty procedures. Fluctuations in CFU/m3 are displayed as a function of time (minutes) in Figure 1 (Control) and Figure 2 (SUCAS). It is evident that certain periods of time are associated with very high air bacterial content, a potential risk of surgical wound contamination.
