To detect the contaminate of faucets in hospitals and the splash during hand washing, and to explore the reasonable layout of hand washing pools. Two faucets with roughly the same spatial layout in the ICU of a third-class first-class general hospital were selected, and the farthest splashing distance and specific splashing points were measured by color paper. Samples were detected by ATP detection technology and routine microbial detection method, and the contaminate of faucets was analyzed. After 72 h of daily hand-washing activities, the furthest distance to the splash point was about 100 cm around the faucet, and the place 40-110 cm around the faucet was contaminated seriously. The farthest distance that the splash point reached was about 80 cm around the faucet with the center of the circle, and the area 40-60 cm around the faucet was heavily contaminated. The distance from the water outlet of the long handle and the short handle faucet to the detection point had a high negative correlation (r = - 0.811, P < 0.001) and a moderate negative correlation (r = - 0.475, P = 0.001) with the number of splash points, respectively. The qualified rates of ATP detection and microbial culture were 25% and 15%, respectively. Pseudomonas aeruginosa, Staphylococcus epidermidis, and other pathogenic bacteria were detected in the water outlet of the faucet and the surrounding environment. Safe hand hygiene facilities are one of the important guarantees of hand hygiene effect. Clean objects and objects related to patients should not be placed within 1 m range near the water outlet of faucet. Anti-splash baffle should be installed as much as possible when conditions permit to reduce the contaminate caused by splash during hand washing.
为了检测医院水龙头的污染和洗手时的飞溅情况，并探讨洗手池的合理布局。选择了一家三级甲等综合医院 ICU 中空间布局大致相同的两个水龙头，用彩纸测量最远的飞溅距离和具体的飞溅点。采用 ATP 检测技术和常规微生物检测方法对样本进行检测，分析水龙头的污染情况。在每天 72 小时的洗手活动后，水龙头周围 100cm 左右的飞溅点距离最远，水龙头周围 40-110cm 处污染严重。水龙头中心周围的飞溅点最远可达 80cm 左右，水龙头周围 40-60cm 处污染严重。长柄和短柄水龙头出水口到检测点的距离与飞溅点数量呈高度负相关(r = -0.811，P < 0.001)和中度负相关(r = -0.475，P = 0.001)。ATP 检测和微生物培养的合格率分别为 25%和 15%。在水龙头出水口及其周围环境中检测到铜绿假单胞菌、表皮葡萄球菌等病原菌。安全的手部卫生设施是手部卫生效果的重要保证之一。清洁物品和与患者相关的物品不应放置在水龙头出水口 1m 范围内。在条件允许的情况下，应尽可能安装防溅挡板，以减少洗手时飞溅造成的污染。
