The objective of this study is to determine whether the Air Barrier System (ABS) reduces airborne colony-forming units (e.g. bacteria) present at surgery sites during posterior spinal procedures

Condition Intervention
Device: Air Barrier System device

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Basic Science

Primary Outcome Measures:
  • CFU density [ Time Frame: Surgical case CFU density will be determined at up to 1 month from completion of surgical cases ] [ Designated as safety issue: No ]
    Colony-forming unit density at incision site (CFU/m3)

Estimated Enrollment: 30
Study Start Date: November 2011
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No device
Experimental: Device deployed
Device is deployed adjacent to the surgery site and activated.
Device: Air Barrier System device
Device is deployed adjacent to the surgery site and activated.

Detailed Description:

The ABS 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 ABS can reduce the presence of airborne colony-forming units at the surgery site during posterior spinal procedures.
