【摘要】 <正>目的探讨工作人员不戴口罩帽子对洁净ICU空气质量的影响,为洁净ICU的医院感染管理提供依据。方法第1天、第3天只要进入ICU病房所有人员全部戴帽子口罩,第2天、第4天入ICU病房所有人员不戴帽子口罩,但在进行任何操作时按要求戴帽子口罩如吸痰、注射等,采用平板自然沉降法、浮游菌测定法、尘埃粒子计数法对10万级洁净ICU空气进行采样。连续监测4天。更多还原

【Abstract】 Objective The influence on ICU air quality by worker’ s respirator&hat wearing method is studied.The results will help to improve hospital infection management processes. Methods At the first and third day every worker was demanded to wear a respirator and a hat before entering the ICU.At the second and forth day,they were demanded not wearing any respirator or hat.But during all four days,they must wear respirator and hat before any nursing operation.Air quality was sampled by class 100,000 clean air using flat panel natural settlement method,dust planktonic bacteria method and particle counting method. Results 0.5 um dust particles in ICU are lower at day 1 and day 3,.and statistical significance was found(P<0.0 5).5um dust particles are not significant different(P>0.05).But more subsidence bacteria and floating bacteria were detected during the first and third day,statistically significant difference exists(P<0.05). Conclusion ICU staff have no apparent effect on ICU air quality whether they wear respirators or hats. These kinds of behaviour are not the key management elements in clean ICU environment.更多还原
