摘要
目的了解新冠肺炎防控期间基层医疗机构影像室与救护车的感染风险,评估其消毒效果。方法制作专项调查表进行感染风险摸底调查,按照相关要求落实影像室和救护车相关消毒措施,评价其消毒前后卫生状况与消毒效果。结果45家次影像室空气、拍片床、胸片架消毒前后菌落总数中位数差异均有统计学意义(P<0.05),仅影像室空气卫生达标率差异有统计学意义(P<0.01);45家次救护车的救护室空气、担架、门把手(内侧)消毒前后菌落总数中位数差异均有统计学意义(P<0.01),卫生达标率差异均有统计学意义(P<0.05);15车次救护室空气、担架采用3种化学消毒剂消毒合格率差异均有统计学意义(P<0.05)。结论5家镇卫生院影像室与救护车存在一定的感染风险隐患,影像室紫外线灯管的配置应进一步规范,室内物体表面消毒应针对不同对象选用有效的消毒剂进行擦拭或喷雾;救护车室内空气消毒可将3%过氧化氢超低容量喷雾消毒作为首选方法。
Objective To understand the infection risk of imaging rooms and ambulances in primary medical institutions during the prevention and control of COVID-19,and to evaluate their disinfection effects.Methods A special questionnaire was made to conduct a thorough investigation of infection risk,and relevant disinfection measures for imaging rooms and ambulances were implemented according to relevant requirements,and the sanitation status and disinfection effect before and after disinfection were evaluated.Results There was a statistically significant difference in the median of total number of colonies before and after disinfection of the air,filming bed,and chest X-ray rack in 45 imaging rooms(P<0.05),and there was a statistically significant difference only in the control rate of air hygiene of the imaging room(P<0.01);there was a statistically significant difference in the median of total number of colonies before and after disinfection of the air,stretcher,door handle(inside)of the room in 45 ambulances(P<0.01),and the differences in the control rate of sanitation were statistically significant(P<0.05).The air and stretchers of 15 ambulance rooms were disinfected with three chemical disinfectants,and there were statistically significant differences in the qualified rates(P<0.05).Conclusion There are certain hidden dangers of infection in the imaging rooms and ambulances of the five town health centers.The configuration of the ultraviolet lamps in the imaging rooms should be further standardized.The disinfection of indoor surfaces should be wiped or sprayed with effective disinfectants for different objects;Air disinfection can use 3%hydrogen peroxide of ultra-low volume spray disinfection as the first choice.
