针对连台手术过程中手术室空气污染问题 ,在连台手术间隙采用三氧消毒灭菌机对室内空气消毒30min ,然后进行空气细菌培养。结果 :第 1台、第 2台术毕空气经消毒后 ,空气中平均细菌清除率分别为87.18%和 84.13%,且达到卫生学标准。说明连台手术间隙 ,采用三氧消毒机短时消毒 ,能有效地降低空气中细菌含量 ,这为病人提供安全的手术环境和预防术后感染具有十分重要的意义。 Aiming at the problem of air pollution in the operation room during the operation, the air in the room was disinfected for 30 minutes in a continuous airway with three oxygen sterilizing and sterilizing machines, and then air bacterial culture was carried out. Results: The average airborne bacterial clearance rates of the first and the second sets of air were 87.18% and 84.13%, respectively, and reached the hygiene standard. That with even the surgical gap, the use of short-term disinfection of ozone disinfection, can effectively reduce the bacterial content in the air, which provides a safe surgical environment for patients and prevention of postoperative infection is of great significance.
