摘要
目的 :监测医院环境空气中肠杆菌的含量 ,评价消毒效果 ,探讨院内感染与气源性因素的相关性。方法 :选择使用LWC - 1离心式空气样品采样器采样 ,用麦康凯选择性培养基细菌培养 ,对神经内科病房、走廊、污被服仓库及治疗室 ,在 3个测量日期消毒前后采集 30个空气样本。结果 :病房环境空气消毒前 16 1cfu/m3 ,消毒后 84cfu/m3 。消毒效果明显 (P <0 .0 5 )。结论 :卧床和便失禁病人的排泄物对病房用品和环境空气造成污染。高浓度的革兰氏阴性肠杆菌气溶胶构成下呼吸道感染威胁。减少粪便污染 ,定时监测和加强病房消毒处理 ,是降低医院内气源性感染的重要措施。
Through moniting of the airborne enterobacteriacene concentration in hospital ward circumstance man can evaluate the air quality and disinfection effect,and then proceed to inquire into the interrelation between hospital associated infection and airborne bacterium.Using LWC-1 (RCS) sampler and selectiv MacC air samples were sampled at wards,corridor,contaminated depositiry and therapying chamber.Altogether 30 samples were collected on 3 dates.The enterobacter concentration were 161 cfu/m 3 and 84cfu/m 3 before and after disinfection respectivly.The results suggested that excrement of patients keeping the bed could cause the contamination of ward air.For reducing the air contamination by stool ward management should be reinforced,so that hospital acquired infection will play down.
