Abstract:
OBJECTIVE:To compare three sterilizing methods for reusable medical goggles.
METHODS:A total of 180 medical goggles of the same brand and same model were randomly divided into three groups. In group A the goggles were first soaked with 2000 mg/L chlorine-containing disinfectant and then cleaned manually; goggles in other two groups were sterilized using pre-programmed automatic spray cleaning and disinfection machine, the disinfection program was set to 90 ℃ for 5 min in group B and 70 ℃ for 30 min in group C. The quality of the sterilization was monitored by visual inspection with luminous magnifying glass and residual protein detection assay. User satisfaction on cleanliness of medical goggles, clarity of mirror surface and suitability of elastic bands was investigated with questionnaire survey.
RESULTS:The qualification rates verified by visual inspection were 82.4%, 84.6%and 98.3%in group A, B and C, respectively, the qualification rate in group C was significantly higher than those in group B and group C (all
CONCLUSIONS:Machinery sterilization set 70 ℃ for 30 min has better cleaning and sterilizing effects for reusable medical goggles.
