135例医院鼠伤寒沙门菌感染流行因素探讨

Epidemic factors of nosocomial infection caused by Salmonella typhimurium

目的 探讨某院儿科鼠伤寒沙门菌医院感染的流行因素。方法 挑选经大便培养证实感染鼠伤寒沙门菌的住院患儿 ,对其住院病房易被该菌污染的区域如床头柜、中床单、暖气片进行采样和细菌培养 ;之后用稀释的 84消毒液进行抹拭消毒 ,2 4h后再采样和细菌培养。结果 消毒前鼠伤寒沙门菌污染阳性率为 4 0 %～6 2 .6 0 % ,消毒后的阳性率为 1 6 .6 7%～ 33.33% ,统计学检验 ,差异有显著性。结论 儿科病房环境污染严重 ,应加强消毒隔离工作。

Objective To evaluate the epidemic factors of nosocomial infection caused by Salmonella typhimurium in a pediatric unit. Methods Environmental samples such as bedside cabinets, sheets and heating radiators were taken from the pediatric unit where children infected with Salmonella typhimurium stayed, and bacterial culture was performed, then these areas were disinfected with '84' disinfectant, and samples of the same areas were also taken for bacterial culture. Results Contamination rates of environment before and after being disinfected were 40%～ 62.60% and 16.67% ～ 33.33% , respectively, there was significant difference between them. Conclusion The contamination in the pediatric unit is severe, disinfection and isolation should be stressed.
