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.

Condition Intervention
Device: Air Barrier System Device

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Basic Science
Official Title: Reduction of Airborne Microbes in the Surgical Field During Spine Procedures Using Directed Local Airflow

Further study details as provided by Nimbic Systems, LLC:

Primary Outcome Measures:
  • Surgery Site CFU Density [ Time Frame: Ten-minute intervals throughout procedure ] [ Designated as safety issue: No ]
    CFU culture counts for samples taken in surgery.

Enrollment: 23
Study Start Date: November 2009
Study Completion Date: December 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No device
Experimental: Device deployed Device: Air Barrier System Device
Device is deployed adjacent to the surgery site and activated so that the filtered air emits over the site.

Detailed Description:

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.
