摘要
目的对气管插管患者床单元高频接触物表面消毒效果调查及分析,为制定环境清洁消毒方案提供依据。方法对4例气管插管患者床单元采用视频回顾法筛选出前5位接触频次最高的物体表面,并连续5 d在每12 h消毒1次的基础上,每6 h进行物体表面采样并细菌培养,通过细菌检出率评价高频接触物表面细菌分布情况和不同采样时间点、不同时段的消毒效果。结果5个高频接触物体表面细菌检出率分别是气管导管接头66.25%、床栏43.75%、胃管接头23.75%、注射泵按钮6.25%和监护仪按钮2.50%,差异有统计学意义(P<0.05);不同采样时间点和不同工作时段细菌检出率对比差异均无统计学意义(P>0.05);清洁消毒后9 h的细菌检出率高于清洁消毒后3 h细菌检出率,差异有统计学意义(P<0.05)。结论气管插管患者床单元高频接触物表面以气管导管接头、床栏和胃管接头的细菌检出率最高,在制定环境清洁消毒方案时应在间隔12 h清洁消毒的基础上,考虑增加这3个高频接触物表面的消毒频次,具体消毒时间有待进一步探索。
Objective To investigate and analyze the disinfection effect of high-frequency contact surfaces in bed units of patients with endotracheal intubation,so as to provide a basis for the development of environmental cleaning and disinfection.Methods The video review method was used to screen out the top 5 surfaces with the high-frequency contact surfaces in the bed units of 4 patients with endotracheal intubation.On the basis of disinfection every 12 hours for 5 consecutive days,the surfaces were sampled for bacterial cultured every 6 hours.The bacteria detection rate was used to evaluate the distribution of bacteria on the high-frequency contact surfaces and the disinfection effect at different sampling time points and time periods.Results The detection rates of bacteria on the surface of the five high-frequency contact objects were:66.25%for the tracheal tube connector,43.75%for the bed rail,23.75%for the gastric tube connector,6.25%for the syringe pump button and 2.50%for the monitor button(P<0.05),with statistics there was no statistical difference in the bacterial detection rate between different sampling time points and different working hours(P<0.05).The bacterial detection rate of 9 hours after cleaning and disinfection in different disinfection periods was significantly higher than that of 3 hours after disinfection,there was statistical difference(P<0.05).Conclusion The high-frequency contact surface of the tracheal intubation is the highest in the bronchial tube joint,the bed column and the gastric tube joint should be considered on the basis of cleaning and disinfection at intervals 12 h when developing an environmental cleaning disinfection plan,and the specific disinfection time needs further to explore.
