Research in using cycle of Lu Wofu lubricant preservation / 中国实用护理杂志

Objective To explore the effective using cycle of Lu Wofu lubricant preservation with different cleaning methods,and provide basis for change time of lubricant preservation.Methods 20 000 bricant was ensured under sterile conditions.400 pieces of the same equipment were extracted from surgical instruments every day,and they were randomly divided into the manual cleaning group and the mechanical cleaning group with 200 pieces in each group,each group adopted manual cleaning and mechanical cleaning.The Lu Wofu lubricant was reused and preserved for one week.Lubricant preservation was extracted and sent to do bacterial culture with fixed people,time and quantity.Results of two groups were compared.Results The qualified rate of the two groups at 24-hour was 100%,at 48-hour the manual cleaning group was 92%,the mechanical cleaning group was 77%,at 72-hour the manual cleaning group was 81%,the mechanical cleaning group was 19%,above 72 hours; both the manual cleaning group and the mechanical group was zero.Over 48 hours in the mechanical group and above 72 hours in the manual cleaning group appeared more than 10 million bacterial colonies.There was significant difference between the two groups.Conclusions The effective using cycle of Lu Wofu lubricant preservation was 72 hours for manual cleaning and 48 hours for mechanical cleaning,the manual cleaning delays one day over mechanical cleaning to change lubricant,which can reduce the waste of resources and cost savings.

Different Kinds of Cleaning Methods for Moderately Contaminated Instruments in Hospital Supply Center:Investigation on Results / 中华医院感染学杂志

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
