摘　　要：目的:了解医院内医务人员随身携带物品带菌现状,探讨不同消毒方法对医务人员随身携带物品的消毒效果,为医院感染管理提供科学依据。方法:选取温州医科大学附属第二医院育英儿童医院门诊、外科、内科科室的医务人员,并收集随身携带的5类高频接触物体表面(使用中的手机、医用笔、手表或挂表、胸牌、钥匙)共135份样品。采用酒精(酒精组)、500 mg/L含氯消毒液(含氯消毒液组)和双链季铵盐一次性消毒湿巾(一次性消毒湿巾组)进行消毒,并在消毒前及消毒后5 min、2 h、4 h采样统计物表面菌株数及菌种。比较三种消毒方法消毒后不同时刻的消毒效果。结果:未经清洁消毒的医务人员随身携带物品表面合格率仅为12.5%,污染较严重,细菌种类较多。消毒后5 min,一次性消毒湿巾组和含氯消毒液组的细菌减少效果显著优于酒精组(P<0.05),细菌数量分别从消毒前的(12.36±3.11)cfu/cm^(2)、(12.64±3.98)cfu/cm^(2)和(12.09±4.15)cfu/cm^(2)降至(0.40±0.18)cfu/cm^(2)、(0.31±0.11)cfu/cm^(2)和(1.62±0.54)cfu/cm^(2)。消毒后2 h和4 h细菌数量回升,但一次性消毒湿巾组和含氯消毒液组的细菌数量仍然低于酒精组(P<0.05)。结论:医务人员随身携带物品的细菌污染问题严重,消毒效果在应用后的初期最为显著,一次性消毒湿巾和含氯消毒液在短期内显示出比酒精更优的消毒效果,建议选择高效的消毒剂并适当频繁地应用。Objective:To understand the current situation of bacterial contamination of personal belongings carried by medical staff in hospitals,and to explore the effect of different disinfectants on the personal belongings carried by medical staff,so as to provide reference for hospital infection management.Methods:A total of 135 samples of five types of high-frequency contact objects(mobile phones,medical pens,watches,badges,keys)were collected from the medical staff working with the outpatient,surgical,and internal medicine departments of the Second Affiliated Hospital&Yuying Children’s Hospital of Wenzhou Medical University.Alcohol(alcohol group),500 mg/L chlorine containing disinfectant(chlorine containing disinfectant group),and disposable double chain quaternary ammonium salt disinfectant wipes(disposable disinfectant wipes group)were used for disinfection,and the surface bacterial count and species were sampled and analyzed before disinfection and 5 minutes,2 hours,and 4 hours after disinfection,and then their disinfection effect at different time points after disinfection was compared.Results:The surface qualification rate of medical personnel carrying items without cleaning and disinfection was only 12.5%,indicating severe contamination and a wide variety of bacterial species.Five minutes after disinfection,the disposable disinfectant wipes group and chlorine disinfectant group showed significantly better bacterial reduction compared with the alcohol group(P<0.05),with bacterial counts decreased from(12.36±3.11)cfu/cm^(2),(12.64±3.98)cfu/cm^(2),and(12.09±4.15)cfu/cm^(2)to(0.40±0.18)cfu/cm^(2),(0.31±0.11)cfu/cm^(2),and(1.62±0.54)cfu/cm^(2),respectively.Although bacterial counts increased at 2-hour and 4-hour points,the levels in the disposable disinfectant wipes and chlorine disinfectant groups remained significantly lower than in the alcohol group(P<0.05).Conclusion:Items carried by medical staff in hospitals has serious bacterial contamination.The disinfection effect is most significant in the initial st
