NCT03473405

Brief Summary

This 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 total knee arthroplasty surgeries.

Outcome Measures

Primary Outcomes (1)

  • Compare the number of colony-forming units captured at incision sites

    A length of tubing will be placed at the incision and will draw air onto agar plates that are changed every ten minutes in both the control and ABS arms.

    Four months

Study Arms (2)

Control

SHAM COMPARATOR

In the control arm, the ABS device will be placed as usual on the patient, but the airflow will NOT be activated. Only the technician in the room will be aware whether the device is turned on or not.

Other: Control

Air Barrier System

EXPERIMENTAL

In the experimental (intervention) arm, the ABS device will be placed as usual on the patient, and the airflow will be activated. Only the technician in the room will be aware whether the device is turned on or not.

Device: Air Barrier System

Interventions

The Air Barrier System is a device that uses localized clean air flow to shield a surgery site from ambient airborne microorganisms that are shed into the air from people present in the operating room.

Air Barrier System
ControlOTHER

The Air Barrier System will be deployed onto the surgical field, but the airflow will not be activated, so this is a sham control comparator.
