动态环境下母婴同室空气质量的检测与分析

Detection and analysis of air quality in mother and baby room during nursing

目的了解动态环境下母婴同室空气中细菌的含量。方法对母婴同室空气进行晨间护理前、后及通风后采样;晨间护理后经过消毒及消毒后2h,随机抽取225份样本做监测对比。结果晨间护理前空气中细菌含量平均合格率为8.82%;晨间护理结束后平均合格率为0;通风后平均合格率为32.07%,与晨间护理前比较,差异有统计学意义(χ2=6.32,P<0.05);消毒后空气中细菌含量平均合格率为67.30%;消毒后2h平均合格率为16.32%,与晨间护理前比较,差异无统计学意义。结论采取通风的方法,能提高动态环境下母婴同室空气的质量。

OBJECTIVE To investigate the microorganism volume of air in the mother and baby room during nursing. METHODS Samples of air were collected before nursing, after nursing, ventilation, disinfection and two hours after disinfection respectively from the mother and baby room, of which 225 samples were selected randomly and compared. RESULTS The qualified rate of the microorganism volume of air in the mother and baby room was 8.82% before nursing and 0% after nursing. The qualified rate of the microorganism volume 32. 07% after ventilation was significantly different compared to that before nursing 8. 82% （x^2 = 6. 32, P 〈 0.05）. The qualified rate of the microorganism volume was 86.53% after disinfection, 16.32% 2 h after disinfection, there was no significant difference compared with 8. 82% before nursing （x^2 = 0. 98, P≥0. 05）. CONCLUSION By ventilation, it is capable to improve the air quality in the mother and baby room during nursing.
