改良式全自动清洗消毒机对复用物品清洗效果的研究

Cleaning effect of improved automatic washing and disinfecting machine to reusable items

目的观察改良式全自动清洗消毒机降低医院消毒物品交叉感染的效果,为提高医院物品消毒质量提供参考。方法医院院感科自行设计改良式全自动清洗消毒机于2012年5月-2013年5月供应中心启用,对启用期间(观察组)医院复用湿化瓶的清洗消毒效果进行统计,并与启用前(对照组)数据进行比较,分析改良式全自动清洗消毒机降低医院复用消毒物品交叉感染的意义;所得数据采用SPSS17.0软件进行统计分析。结果观察组对湿化瓶清洁度常规抽样检测和消毒效果抽样监测合格率均为100.0%,明显优于对照组的合格率92.8%和95.0%,差异有统计学意义(P<0.05);观察组采用改良式全自动清洗消毒机后湿化瓶耗损率为0.5%,明显低于对照组的3.4%,差异有统计学意义(P<0.05)。结论改良式全自动清洗消毒机操作简易可靠,能够提高院内复用湿化瓶的清洗消毒效果,并具有良好的重现性和实用性,可在同级医院推广应用。

OBJECTIVE To observe the effect of reducing the nosoeomial cross-infection by using the improved automatic cleaning and disinfecting machines, so as to provide reference to improving the quality of disinfection in hospital. METHODS The automatic cleaning and disinfecting machines designed and improved by hospital were used in May 2012 to Dec. 2012 period in supply centers. Record the effect of hospital multiplexing wet bottle of cleaning and disinfecting by using improved machines （observation group） and the effects before using the new ma- chines to analyze the meaning of using the automatic cleaning and disinfecting machines. SPSS17.0 software was used for statistical analysis. RESULTS The percent of pass in observation group was 100%, which was significantly better than the control group with the pass rate of 92.8% and 95.0% （P〈0.05）. the coefficient of losses for the wet bottle was 0. 5 % in observation group using improved automatic cleaning and disinfecting machines, which was significant lower than 3.4 % in control group （P〈0.05）. CONCLUSION Improved automatic cleaning and dis- infecting machines are easy to operate, reliable, and able to improve the reuse sterile hospital cleaning and disinfec- tion effects with a good reproducibility and practicability, which should be expanted to same level hospitals.
