Study: Covering the instrument table decreases bioburden

Editor's Note

A significant decrease in bacterial bioburden on the instrument table was found when the table was covered during static periods of nonuse and dynamic periods of active OR use in this study.

Bacterial contamination of the instrument table was evaluated by settle plates in static and dynamic ORs, and airborne particulate and bacterial contaminants were sampled throughout the room. The table was covered with sterile impervious paper covers, sterile plastic covers, or no covers.

Covering the instrument table during static and dynamic OR conditions resulted in a significantly decreased bacterial load on the table. There were no differences between paper and plastic covers.

Instruments table covers should be considered during periods of nonuse and active surgery to decrease bacterial bioburden near the instruments, the researchers conclude.
