目的探讨在有卧床病人时母婴同室病房的空气消毒。方法利用平板沉降法采样培养法,对食醋消毒母婴同室病房空气的效果进行观察。结果用浓度为25g/L的食醋3～10ml/m3加热熏蒸30 min,母婴同室病房在行食醋熏蒸前细菌数为400～800 cfu/m3,而消毒后细菌数为75～150 cfu/m3。结论母婴同室病房使用食醋熏蒸法进行空气消毒可降低病房菌数,预防院内呼吸道感染。 Objective To investigate the air disinfection of maternal and infant ward with bedridden patients. Methods The method of flat sedimentation sampling and culture was used to observe the effect of vinegar disinfection on the air in the same ward of the same room. Results The fumigation of fumigated with 3 ~ 10ml / m3 of vinegar with a concentration of 25g / L for 30 min resulted in 400 ~ 800 cfu / m3 of bacteria before fumigation with the same room in maternal and infant wards, while the number of bacteria after disinfection was 75 ~ 150 cfu / m3. Conclusion The use of vinegar fumigation air disinfection in maternal and infant wards can reduce the number of wards and prevent Nosocomial respiratory tract infections.
