Device to Reduce Surgery Site Contamination - Spine
Reduction of Airborne Microbes in the Surgical Field During Spine Procedures Using Directed Local Airflow
The objective of this study is to determine whether the Air Barrier System device reduces airborne colony-forming units (e.g. bacteria) present at a surgery site during spinal procedures.
The Air Barrier System is a device that uses localized clean air flow to shield a surgery site from ambient airborne contamination. This study examines the hypothesis that the Air Barrier System can reduce the presence of airborne colony-forming units at the surgery site during spinal procedures.
Not Applicable
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Basic Science
Device: Air Barrier System Device
Device is deployed adjacent to the surgery site and activated so that the filtered air emits over the site.
  • No Intervention: No device
  • Experimental: Device deployed
    Intervention: Device: Air Barrier System Device
