PurposeDuring patient transport from operating room to post-operative recovery area, anesthesia staff are at increased risk of particle aerosolization from patients despite wearing face shields. Current single-use face shields do not provide anesthesia staff from adequate protection from bioaerosolized particles expired during a patient's cough, particularly during transfer from the operating room to the post-anesthesia recovery unit. In this study, we compare the efficacy of single-use face shield currently available at our institution to a newly designed face shield that provides better protection while still maintaining cost-effectiveness and the ease-of-use of a disposable device.Materials And MethodsA patient actor, simulated movements from a patient post-procedure, during transport from operating room to postoperative recovery area. Patterns of exposure of bioaerosolized particles produced from a cough between different face shields was evaluated using fluorescein dye.Main ResultsMore extensive coverage of the lower face, as provided by the Enhanced Protection Face Shield, offers improved droplet protection from bioaerosolized particles emitted from a cough.ConclusionsTransfer from the operating room to the post-operative recovery unit is a hands-on process and involves managing multiple aspects of patient care physically. Current single-use face shields are convenient and cost-effective, but do not provide adequate protection from droplet aerosolization by patients during transfer. Other masks that provide adequate coverage are costly and are not designed to be single-use. A single-use disposable face shield that offers improved coverage of the lower face provides improved protection for anesthesia staff while maintaining cost-effectiveness, ease-of-use, and infection control.Copyright © 2020 Elsevier Inc.
