目的比较使用全自动内镜清洗消毒机(AER)前不同预清洗流程对胃镜清洗消毒效果的影响,探索快速有效的预清洗方法。方法将80条待清洗胃镜随机分为2组,分别采用现有清洗流程和简化清洗流程处理,通过胃镜内腔细菌计数,外表面血液、蛋白残留检测等方法,对2种预清洗流程进行微生物及有机物清除效果的比较。结果2种预清洗流程清洁前、后胃镜内腔细菌清除率、血液残留阳性率差别无统计学意义(P>0.05);经AER再处理后菌落数均为0,达到合格标准。简化清洗流程组清洁后蛋白残留阳性率为27.5%,小于现有清洗流程组55.0%,差异有统计学意义(P<0.05)。结论简化清洗流程在保证内镜消毒效果的同时,缩短了时间,节约了成本,提高了内镜的周转率。
Objective To compare the effects of different pre-cleaning procedures on gastroscope cleaning and disinfection before automatic endoscope cleaning and disinfecting (AER), and to explore a quick and effective pre-cleaning method. Methods Eighty gastroscopes to be cleaned were randomly divided into two groups. The two kinds of pre-cleaning procedures were carried out by using the existing cleaning procedure and the simplified cleaning procedure respectively. The two pre-cleaning procedures were carried out by means of gastroscopy, bacterial count, blood on the outer surface and residual protein. And organic matter removal effect comparison. Results There was no significant difference in the bacterial clearance rate and the positive rate of residual blood between the two pre-cleaning procedures before and after gastroscope (P> 0.05). After AER reprocessing, the number of colonies was 0 and reached the acceptable standard. The positive rate of protein residue in the simplified cleaning process group was 27.5% after cleaning, which was less than 55.0% of the existing cleaning process group, the difference was statistically significant (P <0.05). Conclusions The simplified cleaning process can shorten the time, save the cost and increase the turnover rate of the endoscope while ensuring the endoscopic disinfection effect.
