ABSTRACT
OBJECTIVE To compare the difference of testing cleaning effectiveness in the operation instrument between the eye measurement and hemoglobin enzyme test.METHODS Five batches of instrument after cleaning were tested by two methods.RESULTS By eye inspection,all tested samples were qualified.However there were only 76 percent of samples qualified according to enzyme test.CONCLUSIONS Compared with eye inspection,enzyme test is a more sensitive method.Enzyme test can better assess the cleaning effectiveness than others.
ABSTRACT
OBJECTIVE To seek for an effective,rapid,economic,safety and practical cleaning method,so as to ensure the high quality of sterilization in hospital supply center.METHODS Six hundred moderately contaminated recyclable instruments were divided into three groups randomly,conventional group,experimental group A and experimental group B(two hundred sorts each).The instruments in experimental group A were put into warmed water(40 ℃) for ten minutes first,and that in experimental group B were put into multi-enzyme solution for five minutes first,and then all the instruments in three groups were put into automatic sprinkling cleaning machine to accomplish the cleaning process automatically.After cleaning process,cleaning degree of the instruments and remained blood residues were compared in three groups.RESULTS The cleaning quality in the groups A and B was significantly higher than that of the conventional group,both P
