目的 探讨自制除烟装置降低手术烟雾中有机物质浓度的作用。方法 将除烟装置应用于腹腔镜胆囊切除手术患者。50例患者随机分为对照组(25例)和实验组(25例)。对照组术中从操作Trocar阀门开关处接1个导气管,导气管的另一头连接检测仪的探头。实验组术中从操作Trocar阀门开关处接1个导气管,导气管连接自制除烟装置,检测仪探头置除烟装置末端开口处。检测两组手术烟雾中有机物浓度。结果 实验组七氟烷、环戊烷、乙苯十一种有机物浓度较对照组显著降低,除烟装置对有机物的清除率最高的是环乙酮,达到94.03%,十烷达到33.57%,对十一种有机物平均清除率为73.22%。结论 自制除烟装置能够安全有效过滤手术烟雾中有机物,为医护人员提供优质的手术室内空气环境。

Objective To investigate the effect of a self-made fume-extracting device in reducing the concentration of organic components of surgical smoke, and to provide evidence for purifying the air in the operating room.Methods The self-made fume-extracting device was applied to the patients undergoing laparoscopic cholecystectomy. Fifty eligible patients were randomly divided into the experimental and control groups. In the experimental group, one end of the pneumoperitoneum tube was connected to the trocar valve switch and the other end was connected to the self-made fume-extracting device. The detector probe was attached to the end of the device. In the control group, one end of the pneumoperitoneum tube was connected to the trocar switch, while the other end was connected to the probe of the detector. The concentrations of organic components of surgical smoke were detected and analyzed between the two groups.Results The concentrations of seven halothane, cyclopentane and ethylbenzene in the experimental group were significantly lower than those of the control group. The highest clearance rate of the self-made fume-extracting device reached 94.03% with acetophenone, and the lowest clearance rate was 33.57% with n-decane. The average clearance rate of this self-made fume-extracting device in the process of adsorbing organic components was 73.22%.Conclusions The self-made fume-extracting device can safely and effectively filter the surgical smoke and provide high-quality air for the medical staff in the operating room.
