room[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2024, 54(2): 141-145.
Abstract：Objective: To study dynamic monitoring of air quality at differenttime during cataract phacoemulsification surgery in the clean operation room so as to provide references for the development of consecutive operation mode. Methods: Air quality detector and air microorganism sampler were used to dynamically evaluate the air quality during cataract phacoemulsification surgery. Results: The air cleanliness during the entire process of cataract phacoemulsification surgery from patient entry to incision closure was in an“N” shape, with the highest concentration of particulate matter in the air at the beginning of anesthesia, showing significant difference (P<0.01). The aerosol concentration in the surgical area of 12 consecutive cataract phacoemulsification operations showed a steady wave trend from the 1st to the 7th, while PM2.5 (0.17 μg/m3) and PM10 (0.27 μg/m3) showed an upward trend from the 8th, with a significant high value (PM2.5 0.3 μg/m3, PM10 0.4 μg/m3, particle number 21.67/L) during the 12th, when the detection of planktonic bacteria was 2 cfu/m3; the aerosol concentration in the surrounding area showed steady fluctuation, which met the dynamic standard.Conclusion: A clean operating room can continuously and effectively maintain the cleanliness of the air in the operating room and the consecutive operation mode is feasible. Considering the clinical manpower arrangement and practical work, it is recommended that 11 or 12 cataract phacoemulsification surgery (4 to 4.5 hours) be consecutively performed to ensure the management efficiency of the operating room.
