探讨手术不同步骤对手术烟雾中PM10浓度变化的影响

目的:探讨在手术中不同步骤的PM10浓度变化及影响因素;方法:采用随机数字表将研究对象分为天花送风装置区域内、外两组,应用P-5型数字粉尘仪在术者口鼻处和巡回护士口鼻等高处(距手术切口上方50cm左右)进行测量,自制问卷收集记录手术过程中不同的手术步骤对pm10的浓度变化;结果:手术烟雾中PM10的浓度低于大气中PM10的标准浓度;术野暴露、组织分离和切口关闭时PM10浓度是手术过程中PM10的均值浓度的影响因素,不同手术方式、是否使用电刀与手术过程中PM10的均值浓度成正相关,不同性别与手术过程中PM10的均值浓度成正相关;结论:手术全过程中PM10的浓度符合国家标准;术野暴露时PM10浓度可以作为预测整个手术PM10的平均浓度,术野暴露时浓度越高,PM10均值浓度越高;不同体脂含量的患者对手术烟雾中PM10浓度有正向影响。

objective:to study the different steps in the operation of PM10 concentration change and influence factors;Methods:using random Numbers table object of study can be divided into air supply device inside and outside two groups of smallpox,application of P-type 5 digital dust in the butcher nose and mouth and high such as itinerate nurse muzzle(50 cm)away from the incision above measure,self-madequestionnaire collected surgery different operation steps of PM 10 concentration in the process of change;Results:the operation of the smoke of PM10 concentration is lower than the standards of PM10 concentration in the atmosphere;Operative field exposure,intraoperative and cut off the PM10 concentration is the mean of PM10 concentration in the process of operation factors,the influence of different operation methods,whether to use the electric knife and PM10 is closely relative to the mean concentration in the process of operation,different gender and operation process of the average PM10 concentration positive correlation;Conclusion:the concentration of PM10 in the whole process of operation in line with the state standards;Operative field exposure of PM10 concentration can be predicted as the entire operation of PM10 concentration on average,the operative field exposure concentration is higher,the higher the average PM10 concentration;The patients of different body fat has a positive effect on smoke PM10 concentration in surgery.
