Source-control strategies and efficacy.

We have presented a source-control technology that addresses all three areas of concern. Using waste anesthesia gases as a marker for the efficacy with which the source-control system could control the dissemination of respiratory and bloodborne pathogens, the system reduced exposure to virtually undetectable levels. We thus conclude that source-control is a cost-effective method of markedly reducing the risk of infectious disease transmission in the perioperative setting for both patients and personnel.
