Abstract

Objective To evaluate the air purification effect of laminar ventilation system and central negative pressure suction device for the scientific use of the device. Methods A portable air quality detector was used to measure the air concentration of PM2.5 and CO₂in the operating room of a tertiary hospital in Hunan Province, and to evaluate the air purification effect of the exhaust device. Results The concentration of PM2.5 and CO₂ increased significantly at the time of surgery; the concentration of PM2.5 and CO₂ in the “laminar ventilation” operating room was lower than in the ordinary operating room; in the open surgery and endoscopic surgery, the smoke removal effect of “laminar ventilation + central negative pressure device” was better than the “laminar ventilation” device. Conclusion “Laminar ventilation system” can reduce the concentration of PM2.5 and CO₂ in surgical smoke, and the combined use of “laminar ventilation system” and “central negative pressure suction device” is better.
