目的对某家大型综合性医院部分病区医护用水、患者病房用水、水龙头内壁生物膜形成及多重耐药菌定植情况进行采样并分析,了解病区供水的污染状况。方法对该院某新外科大楼11个病区的37个水龙头位置,包括医护用水龙头、病房水龙头及淋浴头采集水样,并对水龙头及淋浴头内壁进行采样培养,得出水样合格率及生物膜形成情况。对该院另一较老外科楼12个病区的30个水龙头内壁进行采样、培养,分析内壁中多重耐药鲍曼不动杆菌及耐甲氧西林金黄色葡萄球菌(MASA)的检出率。结果抽查21个医护用水龙头出水,2个不合格,合格率为90.48%;共抽查病房水龙头出水8个,淋浴头出水8个,均合格。37个水龙头内壁,均有生物膜形成。共调查水龙头内壁30个样本,包括医护洗手用水龙头14个、病房水龙头8个、淋浴水龙头8个、内壁MASA检出率为0,多重耐药鲍曼不动杆菌检出率为60.00%,其中医护用水龙头检出率为72.70%,病房水龙头为50.00%,病房淋浴头为75.00%。结论医院病房的供水水龙头生物膜形成情况严重,且多重耐药鲍曼不动杆菌定植率高,有发生医院感染的潜在危险,应引起相关部门的重视。
Objective To sample and analyze the medical water, patient ward water, faucet biofilm formation and multi-drug resistant bacteria colonization in some ward of a large general hospital to find out the status of water supply in ward. Methods A total of 37 faucet positions in 11 wards of a new surgical building in the hospital were collected, including water taps for medical treatment, taps for faucets and showerheads. Samples were taken from the faucets and the inner wall of the showerhead to obtain the qualified rate of water samples and Biofilm formation. The internal walls of 30 faucets in 12 wards of another older surgical building in the hospital were sampled and cultured. The detection rate of multi-drug resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MASA) . The results of spot checks 21 medical faucet water, 2 failed, the passing rate of 90.48%; a total of 8 wart tap water, shower head effluent 8, are qualified. 37 faucet wall, are biofilm formation. A total of 30 samples of the inner wall of the faucet were investigated including 14 medical hand washing faucets, 8 watertight faucets and 8 shower faucets. The detection rate of internal MASA was 0 and the detection rate of multidrug resistant Acinetobacter baumannii was 60.00% Health care faucet detection rate was 72.70%, ward faucet was 50.00%, ward shower head was 75.00%. Conclusions The faucet biofilm formation in the hospital ward is serious, and the multi-drug resistant Acinetobacter baumannii colonization rate is high, so there is a potential risk of nosocomial infection, which should arouse the attention of relevant departments.
