摘要
目的掌握洁净手术室动态空气质量情况、变化规律及其影响因素,探讨感染防控措施。方法对我院I、II、III级洁净手术室共426台手术分别于手术过程不同时点(手术切皮时、手术进行30分钟、手术进行60分钟以及切口缝合)进行沉降菌、浮游菌和尘埃粒子数监测。同时,记录手术前系统自净时间、手术中室内活动人员数量、台次等情况并进行统计分析。结果静态条件下,沉降菌监测结果均符合要求;动态条件下,尘埃粒子数、浮游菌密度总合格率仅73.24%,III级洁净手术室合格率仅61.54%;经卡方检验,不同年度、不同洁净度级别以及不同条件下的空气质量动态监测结果差异有统计学意义。结论动态空气质量总体较差。净化系统自身状况、洁净度级别、手术过程中室内活动人数、手术台次、术前自净时间等因素为影响手术过程动态空气质量的重要因素。为提高动态空气质量,应加强洁净手术室的使用管理和净化系统的专业维护。
Objective To explore the dynamic air quality,changing tendency and influence factors in clean operation room,and to discuss infection prevention and control measures.Method A total of 426 surgeries in Class I,II,and III clean operating rooms in our hospital were monitored for sedimentary bacteria,airborne bacteria,and dust particle number at different time points during surgery(incision,30 minutes of surgery,60 minutes of surgery,and incision suture).The pre-operative system self-cleaning time,the number of staff in the operation room during the operation,the number of surgeries,etc.were recorded for statistical analysis.Results The results of sedimentary bacteria surveillance were qualified in static conditions.Under dynamic conditions,the total pass rate of dust particles and airborne bacteria density was only 73.24%,and the pass rate of Class III clean operation room was only 61.54%.Chi-square test showed that,the dynamic air quality in different years,different cleanliness levels and different conditions was statistically significant.Conclusion Dynamic air quality is generally poor.Factors such as the state of the purification system,the level of cleanliness,the number of staff in the operation room during the operation,the number of surgeries,and the preoperative self-cleaning time are important factors affecting the dynamic air quality during the operation.In order to improve the dynamic air quality,the maintenance management of the clean operating room and the professional maintenance of the purification system should be strengthened.
