- Provider allergy/intolerance to 64% alcohol: In the case where the primary anesthesia provider conveys a prior allergy to 64% alcohol and/or a history of significant contact dermatitis, the operating room will be excluded from enrollment. If a primary anesthesia provider develops an allergy and/or contact dermatitis during the study period, this will be documented, and operating rooms assigned to the primary anesthesia provider for future cases will be excluded. The expectation will be that all key providers working in operating rooms randomized to the intervention will participate in utilization of the device. If an operating room is randomized and a provider subsequently refuses to participate for any reason, the operating room will be excluded from the primary analysis but included in an intention-to-treat analysis. An additional operating room will be randomized for each such occurrence.
