Innovative Approach to Moderating Risk of Nosocomial Infection During Anesthesia

Infection control concerns abound in the surgical anesthesia workstation placing patients and providers at significant, documented risk as a result of many factors including provider hand hygiene lapses, equipment design and complexity, and challenging disinfection. We performed a trial to mitigate cross-contamination involving 30 general anesthesia surgical cases matched 1:1 as control (no intervention) or intervention group (condom-like barriers to four anesthesia workstation components that are frequently touched and contaminated, and very difficult to disinfect). Wraps were removed at case end, then replaced with fresh ones before the start of the subsequent case. Baseline culture samples were obtained prior to the first surgical case of the day in each room, then performed on cases that followed in each room over a 3-day period. Baseline colony formation units density was equivalent in both conditions with total density significantly lower in the covered/wrapped (Mean Rank = 5.81) vs uncovered condition (Mean Rank = 11.19) at p
