Abstract:
OBJECTIVE To study the possibility of air sterilization with solution of camphor leaves. METHODS Every six adjacent sickrooms that had same volume from 9 different clinical sectors were randomly selected for testing.Air of all sickrooms were sterilized by atomizing with solution of camphor leaves that was rough made by boiling and filtering and by direct irradiating with ultraviolet ray respectively.And then screened the sterilization effect of two methods respectively by air culture. RESULTS After sterilization with 100% solution of camphor leaves,all sickrooms were in line with standard of class Ⅲ(500 CFU/m~3),and 70% sickrooms were in line with class Ⅱ(200CFU/m~3).Both atomizing with solution of camphor leaves and direct irradiating with ultraviolet ray showed obvious effect,the result of air culture indicated that CFU of microorganisms were significant differrent between pre-sterilization and post-sterilization in both methods(P0.25). CONCLUSIONS Camphor leaves are very effective for sterilization and deserve to spread.
