背景和目的：内窥镜检查时不普遍使用面部保护可能使内窥镜医师面临暴露于血液和体液的风险；然而，暴露的频率是未知的。方法：对4名在内镜检查中使用面罩的胃肠病学家进行了为期6个月的前瞻性研究。在治疗前和结束时，以标准化的方式擦拭面罩。对照包括在(1)内窥镜检查室壁、(2)远程患者吸入舱壁和(3)结肠镜检查后立即故意污染后的面罩拭子。拭子培养48小时，报告生长为无生长或菌落形成单位（cfu）数量。比较各组+CFU率和CFU数。结果：239次内镜检查共进行了1100次手术。内镜前组+CFU率（2% ~ 4.8%，无统计学意义）显著低于内镜后面罩组(45.8%，P
Background and Aims: Nonuniversal use of facial protection during endoscopy may place endoscopists at risk of exposure to blood and body fluids; however, the frequency of exposure is unknown.Methods: A prospective 6-month study of 4 gastroenterologists using a face shield during endoscopy was undertaken. The face shield was swabbed in a standardized fashion before and at the end of the session. Controls included pre- and post-swabs of face shields placed on the (1) endoscopy suite wall, (2) remote patient intake bay wall, and (3) after deliberate contamination with a colonoscope immediately after colonoscopy. The swabs were cultured for 48 hours, and growth was reported as no growth or by number of colony-forming units (CFUs). The groups were compared for +CFU rate and CFU number.Results: A total of 1100 procedures were performed in 239 endoscopy sessions. The +CFU rate in the preendoscopy groups (2%-4.8%, not significant) was significantly lower than the postendoscopist face shield (45.8%, P
