Abstract Objective: To analyze the impact of high-speed power systems on the air quality during endoscopic transluminal surgery, and to provide recommendations for intraoperative prevention and control for medical staff in the operating room. Methods: The air during nasal endoscopic transethmoid operation in Eye Hospital Affiliated to Wenzhou Medical University from September to November 2021 was selected as the study object. An air quality detector and an air microbiological sampler were used respectively to measure in real-time at the patient’s nostril level, the level at 50 cm from the patient’s nostril, the level at 1.5 m from the patient’s nostril,and the surrounding areas of the operating room during surgical incision, when the diamond grinding drill was used in the nose, when the micro power planer head was used in the nose, when contaminated high-speed power system was activated in vitro, and 10 minutes after discontinuation of high-speed power systems. The changes in PM2.5, PM10, particle count, and planktonic bacterial concentration generated at the above sampling points were analyzed. Results: With the use of intraoperative high-speed power systems, PM2.5, PM10, and particle count showed a fluctuating upward trend, reaching their peak during in vitro activation, and the concentration of
particulate matter ranked in order from high to low as follows: when the contaminated high-speed power system activated outside the body, when the micro dynamic force cutting blade used inside the nose, and when the diamond grinding drill used inside the nose (P<0.01). The PM2.5 concentration, PM10 concentration and particle
number at different sampling locations were statistically different (P<0.01), with the concentration ranking in order from high to low as follows: patient’s nostril>surgeon’s mouth and nose>instrument nurse’s mouth and nose>operating room’s surrounding area, showing significant difference (P<0.01). The concentration of planktonic bacteria from different sampling locations during surgery was higher than the baseline, with statistical difference (P<0.05). Conclusion: The use of high-speed power system during endoscopic transethmoidal approach will increase the number of particles and bacteria in the air of the operating room, and produce different effect with
different using modes and from difference working distance. Nursing staff should take corresponding prevention and control measures to reduce occupational exposure and prevent from surgical infection.
