本文采用SPRIA法检测医院内医疗器械及外环境物品446份样本,HBsAg阳性率为11.43％(51/446),潜血阳性率为22.42％(100/446)。医院物品表面细菌菌落总数超标率为12.56％(56/446),致病菌分离率为13.68％)(61/446),其中金黄色萄葡球菌46份,沙门氏菌及志贺氏菌各6份,绿脓杆菌3份。空气样本超标率在20～75％之间,提示医院HBV及细菌污染严重,应加强医院管理,严格遵守消毒制度,重视无菌操作,这对减少院内感染及医源性传播有重要的流行病学意义。
In this paper, 446 samples of medical devices and external environment were detected by SPRIA, the positive rate of HBsAg was 11.43% (51/446), and the positive rate of occult blood was 22.42% (100/446). The total number of bacterial colonies on the surface of hospital articles exceeded the rate of 12.56% (56/446) and the pathogenic bacteria separation rate was 13.68% (61/446), including 46 Staphylococcus aureus, 6 Salmonella and 6 Shigella , Pseudomonas aeruginosa 3 copies. Air samples exceeded the standard rate of 20 to 75%, suggesting that hospital HBV and bacterial contamination is serious, should strengthen hospital management, strict compliance with the disinfection system, emphasis on aseptic operation, which reduce the nosocomial infection and iatrogenic transmission of important epidemic Significance of learning.
