两种空气消毒方法对心脏导管室接台手术空气消毒效果比较

目的比较紫外线灯照射和动态空气净化器两种方法对心脏导管室接台手术空气消毒效果.方法分别用两种方法对导管室空气进行消毒,在导管室第一台手术消毒前、后,连台手开始前,连台手术开始后30min、60 min、120 min分别进行采样和细菌计数.结果两种方法对手术前心脏导管室空气均有较好的消毒效果,差异无统计学意义（P〉0.05）;两种方法对空气中的微生物杀灭率均在80%以上.连台手术开始后30 min,两种方法比较差异无统计学意义（P〉0.05）;连台手术开始60 min,两种方法比较差异有统计学意义（P〈0.01）;连台手术开始120 min,两种方法比较差异有统计学意义（P〈0.05）.结论持续应用动态空气净化器对导管室空气消毒效果好,以缩短手术间隔时间,是心脏导管室空气消毒的理想方法.
