Abstract:
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.
摘要:
为了检测医院水龙头的污染和洗手时的飞溅,并探讨洗手池的合理布局。在某三级甲等综合医院的ICU中选取了两个空间布局大致相同的水龙头,用彩色纸测量最远的飞溅距离和具体的飞溅点。样品分别采用ATP检测技术和常规微生物检测方法,并对水龙头的污染进行了分析。每天洗手72小时后,到飞溅点最远的距离是水龙头周围约100厘米,水龙头周围40-110厘米的地方被严重污染。飞溅点达到的最远的距离是以圆心为中心的水龙头周围约80厘米,水龙头周围40-60厘米的区域被严重污染。长柄和短柄水龙头的出水口到检测点的距离呈高度负相关(r=-0.811,P<0.001),与飞溅点数量呈中度负相关(r=-0.475,P=0.001),分别。ATP检测和微生物培养的合格率分别为25%和15%,分别。铜绿假单胞菌,表皮葡萄球菌,在水龙头的出水口和周围环境中检测到其他致病菌。安全的手卫生设施是手卫生效果的重要保证之一。清洁物品和与患者有关的物品不应放置在靠近水龙头出水口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。
