腹腔镜手术CO2气腹的洁净手术间内CO2浓度监测

Monitoring CO_2 concentration in cleansing operation room of CO_2 pneumoperitoneum for laparoscopic operation

目的 观察红外线CO2检测仪监测行腹腔镜手术的洁净手术间内CO2浓度是否符合国家标准。方法选取该院2014年1月1日至2016年3月30日完成的腹腔镜手术及非腹腔镜手术60例患者作为研究对象。选择30个工作日（编注序号为1-30）内行腹腔镜手术（腹腔镜组30例）及行非腹腔镜手术（非腹腔镜组30例）,在洁净手术室进行,以CO2浓度为观察指标,分别测定腹腔镜手术与非腹腔镜手术在不同时段（术后1、2、3、4、5、6 h及大于6 h 7个时段）手术室空气中CO2浓度,对比分析其变化情况。结果 在洁净手术室,腹腔镜组在不同时段手术室空气中CO2浓度存在不同程度的超标现象;而非腹腔镜组CO2浓度未出现超标。腹腔镜手术组与非腹腔镜手术组各时段CO2浓度比较,差异均有统计学意义（P〈0.05）;腹腔镜手术组在不同时间段的总体均数值比较,差异有统计学意义（F=2.636,P=0.037）,非腹腔镜手术组在各个时间段的总体均数值比较,差异有统计学意义（F=2.426,P=0.039）。结论 腹腔镜手术CO2气腹的洁净手术间内CO2浓度超标,相关部门应制订措施改进行腹腔镜手术的洁净手术间内CO2浓度。

Objective To observe whether the carbon dioxide （CO2） concentration in the cleaning operating room for conducting laparoscopic operation monitored by the infrared-red ray detector conforming to the national standard. Methods Sixty cases of laparoscopic operation and non-laparoseopie operation completed in our hospital from January 1,2014 to March 30, 2016 were selected as the research subjects. The 30 working days were selected （labeled serial number of 1,2,3… 30） for conducting the laparoscopic operation （laparoseopic group, 30 cases）and the non-laparoseopie operation （non-laparoscopic group, 30 cases）, which were conducted in the cleaning operation room. The CO2 concentration served as the observation indicator and the CO2 concentrations of operation room air in the laparoscopic operation and the non-laparoscopic operation were respectively detected at different time periods （7 time periods including postoperative 1,2,3,4,5,6 h and over 6 h ）. Their change condition was performed the comparative analysis. Results In the cleaning operating room, different degrees of exceeding standard phenomena existed in the laparoscopic operation group air at different time periods;the CO2 concentration in the non-laparoseopie operation group did not appear the exceeding standard. The CO2 concentrations at various time periods had difference between the laparoscopie group and non-laparoscopic group （P〈0.05） ;the total mean value in the laparoscopie group had differences among various time periods（F=2.636,P=0.037）. Conclusion The CO2 concentration in the cleaning operating room of CO2 pneumoperitoneum for laparoseopic operation exceeds the standard, the corresponding departments should formulating the measures to clean the C02 concentration in the laparoscopic operation room.
