目的探讨使用两种清洗方法清洗中度污染器械的效果,确保复用器械的灭菌质量。方法选取本院外科手术供应室回收中度污染器械300件,使用随机法将其分为三组,即第一清洗组100件、第二清洗组100件及对照清洗组100件。对照清洗组采用全自动喷淋清洗机行常规清洗。第一清洗和第二清洗两组在对照组基础上将器械提前分别采用酶液与温水浸泡。将三组采用不同方法进行清洗后的器械清洁度及残留血的污染情况进行对比分析。结果第一及第二清洗组器械清洁度及残留血的污染情况显著优于对照清洗组。且结果差异有统计学意义(P<0.05)。第一及第二清洗组器械潜血检测阳性率显著低于对照组,且结果差异有统计学意义(P<0.05)。另第一与第二清洗组清洗结果比较无显著差异(P>0.05)。结论使用酶液或温水在应用全自动喷淋式清洗机清洗中度污染器械前进行浸泡,能够明显提高中度污染器械的清洗度,两种方法值得推广。
Objective To explore the effect of using two cleaning methods to clean moderately-contaminated equipment to ensure the sterilization quality of the re-used equipment. Methods A total of 300 medium-polluting instruments were collected from the surgical supply room of our hospital and randomly divided into three groups: 100 in the first cleaning group, 100 in the second cleaning group and 100 in the control cleaning group. Control cleaning group using automatic spray cleaning machine routine cleaning. The first cleaning and the second cleaning two groups on the basis of the control group, respectively, prior to using enzyme solution and warm water soaking. Three groups were cleaned by different methods after the cleanliness of equipment and residual blood contamination were compared. Results The device cleanliness and residual blood contamination in the first and second wash groups were significantly better than that of the control wash group. And the difference was statistically significant (P <0.05). The positive rate of occult blood test in the first and second cleaning group was significantly lower than that in the control group, and the difference was statistically significant (P <0.05). Another first and second cleaning group cleaning results were no significant difference (P> 0.05). Conclusions The use of enzyme solution or warm water in the application of fully automatic spray-washing machine to clean the contaminated equipment prior to soaking, can significantly improve the cleaning of moderately-contaminated equipment, two methods worth promoting.
