Abstract
Objective To compare the effect of three disinfection and cleaning methods on neonatal incubators.Methods After terminal disinfection,neonatal incubators were randomly divided into three groups,and were wiped respectively with 500 mg/L available chlorine(group Ⅰ),250 mg/L available chlorine(group Ⅱ),and water(group Ⅲ) once a day,samples of incubators were taken for bacterial culture immediately after drying and 24 hours after treating,monitor were performed for consecutive 6 days,disinfection or cleaning effect of 3 groups were compared.Results The qualified rate in group Ⅰ,Ⅱ and Ⅲ was 100.00%(36/36),97.40%(75/77),and 96.67%(58/60) respectively when samples were taken immediately;the qualified rate in group Ⅰ,Ⅱ and Ⅲ was 91.67%(33/36),94.81%(73/77),and 96.67%(58/60) respectively when incubator samples were taken 24 hours after treating(all P0.05).Conclusion The above three methods can all meet the environmental hygiene requirements of neonatal units,but water cleaning method is more simple,economical,and environmental protective,which is worth popularizing.
