摘　　要：目的探讨腹腔镜宫颈癌手术中烟雾有毒物质的监测及改良密闭排烟气法的净化作用。方法选取80例实施腹腔镜下宫颈癌根治术患者为研究对象,按照随机数字表法分为两组,各40例。对照组实施以往传统的开放、间断排烟气法,研究组实施本研究应用的改良密闭排烟气法。比较两组手术医师口鼻附近PM10.0和PM2.5水平。比较两组手术开始1 h时空气中一氧化碳和二氧化碳浓度。结果研究组手术医师口鼻附近PM10.0和PM2.5水平均显著低于对照组(P<0.05)。手术开始1 h时,研究组空气中一氧化碳(1.04±0.05)ppm和二氧化碳(528.8±35.6)ppm浓度均显著低于对照组的(3.15±0.17)ppm、(1145.6±117.5)ppm(P<0.05)。结论对腹腔镜下宫颈癌根治术患者,术中行改良密闭式排烟法,能有效的改善手术室空气质量,减少医务人员吸入颗粒性有毒有害物质水平,降低手术室空气中一氧化碳和二氧化碳。Objective To explore the monitoring of toxic substances in smoke during laparoscopic cervical cancer surgery and the purification effect of improved closed smoke exhaust method.Methods 80 patients undergoing laparoscopic radical cervicectomy were selected as the research objects and divided into two groups according to random number table method,with 40 cases in each group.The control group implemented the traditional open and intermittent gas exhaust method,while the research group implemented the modified closed gas exhaust method applied in this study.PM10.0 and PM2.5 levels near the mouth and nose of surgeons were compared between the two groups.The concentrations of carbon monoxide and carbon dioxide in the air were compared 1 h after operation.Results PM 10.0 and PM2.5 levels near the mouth and nose of surgeons in the study group were significantly lower than those in the control group(P<0.05).At 1 h after the operation,The concentrations of carbon monoxide(1.04±0.05)ppm and carbon dioxide(528.8±35.6)ppm in the air of the study group were significantly lower than those of the control group(3.15±0.17)ppm and(1145.6±117.5)ppm(P<0.05).Conclusion For patients undergoing laparoscopic radical hysterectomy for cervical cancer,the improved closed smoke exhaust method can effectively improve the air quality in the operating room,reduce the level of inhaling particulate toxic and harmful substances by medical staff,and reduce carbon monoxide and carbon dioxide in the air in the operating room.
