摘　　要：目的探讨基于前馈控制的预处理保湿措施对金属器械清洗效果的影响。方法将250件样本分别进行8次实验,总共获得2000个样本。每次进行染血处理后,将250件样本随机分为A、B、C、D、E共5组。A组采用纯化水;B组采用1∶200的稀释多酶清洗液;C组采用1∶200的稀释碱性清洁剂;D组采用泡沫酶预处理剂;E组不做保湿预处理。比较5组器械保湿预处理4、24 h后的目测法与隐血试验(OB试验)结果。结果A、B、C、D组保湿预处理4 h后器械表面目测清洗合格率高于E组,B、C、D组器械内壁目测清洗合格率、OB试验合格率高于A组和E组,差异均有统计学意义(P<0.05或P<0.01)。A、B、C、D组保湿预处理24 h后器械表面目测清洗合格率高于E组,D组器械内壁目测清洗合格率、OB试验合格率高于A、B、C组,差异均有统计学意义(P<0.05或P<0.01)。结论泡沫酶预处理剂保湿后清洗效果最佳,碱性清洁剂与酶清洗剂在短时间内对器械保湿处理后清洗效果较好,而纯水保湿处理后清洗效果不佳。Objective To explore the influence of pretreatment and moisturizing measures based on feedforward control on cleaning efficiency of metal instruments.Methods A total of 2000 samples were obtained from 250 samples in 8 experiments.Every time after blood staining,250 samples were randomly divided into groups A,B,C,D and E.Group A was processed with purified water,group B was processed with 1∶200 diluted multi enzyme cleaning solution,group C was processed with 1∶200 diluted alkaline cleaning agent,group D was processed with soaking moisturizing gel,and group E was processed with no moisturizing pretreatment.The results of visual inspection and occult blood test(OB test)were compared between the five groups after moisturizing pretreatment for 4 and24 h.Results The qualified rates of visual cleaning of instrument surface in groups A,B,C and D were significantly higher than those in group E after 4 h of moisturizing pretreatment,and the qualified rates of visual cleaning and OB test of instrument inner wall in groups B,C and D were significantly higher than those in groups A and E(P<0.05 or P<0.01).The qualified rates of visual cleaning of instrument surface in groups A,B,C and D were significantly higher than that in group E after 24 h of moisturizing pretreatment,and the qualified rates of visual cleaning and OB test of instrument inner wall in group D were significantly higher than those in groups A,B and C(P<0.05 or P<0.01).Conclusion The foam enzyme pretreatment agent has the best cleaning effect after moisturizing.The alkaline cleaner and enzyme cleaner have better cleaning effect after moisturizing treatment in a short time,and the cleaning effect of pure water moisturizing treatment is not good.
