Airborne bacteria in the operating room can be reduced by HEPA/Ultraviolet air recirculation system (HUAIRS)

Presented at the Surgical Infection Society (SIS)
37th Annual Meeting May 2017
David Kirschman, MD¹, Soumitra R. Eachempati, MD FACS, FCCM²

Background

Surgical site infections (SSI) are a major cause of morbidity and mortality in US hospitals. Airborne bacteria in operating rooms may contribute to SSI. In Europe but not the US, regulations exist to limit the airborne bacterial levels in the operating theater. In the first part of a multi-part study, we sought to determine whether airborne bacterial levels can be reduced by the HUAIRS system.

Results

The samples of airborne CFU/m3 were measured during surgical procedures over a seven hour sampling period. 12 samples were taken for each of control and HUAIRS periods. The results are as shown below.

For the cultured samples obtained, there was a 67.7% reduction in CFU count in twelve paired samples. This reduction is statistically significant (p=.0163) using a paired T-test.
