Disinfection effect of ultrasonic atomizer of acid oxidation potential water on neonate incubator at NICU

Objective To compare the effect of three disinfection methods on neonate incubator at NICU.Methods After 24 hours terminal disinfection,48 neonate incubators were randomly divided into three groups,16 for each group of units:group I disinfected with available chlorine 500 mg/L,group Ⅱ with 0.25％ iodine volts,and group Ⅲ with acid oxidation potential water.Different disinfection methods were used for the 3 groups.30 min and 24 h after the disinfection,samples were collected for bacteria culture.The culture was monitored for 7 days.The effects of the three groups were compared.Results 30 min after the disinfection,samples were collected from the 3 groups for bacterial culture; the qualified rate was 100.00％ in group Ⅰ,was 93.75％ in group Ⅱ,and was 100％ in group Ⅲ.24 h after the disinfection,the bacterial culture showed that the qualified rate was 93.75％ in group Ⅰ,was 75.00％ in group Ⅱ,and was 81.25％ in group Ⅲ.There were statistical differences in disinfection effect between 30 min and 24 h after the disinfection (P ＞0.05).Conclusion All the three disinfection methods can achieve the environmental hygiene requirements; All samples for bacterial culture were qualified; however,the acid oxidation potential water ultrasonic atomization method is more simple,environment-protective,and time-saving and is worth being generalized.
