摘要:

目的 研究动态环境下局域层流种植手术室尘埃粒子数的变化, 探讨其改变的主要因素。方法 选择口腔种植手术室1间及种植手术20例, 在洁净10 min后患者入室前至手术结束, 每隔15 min采用微粒子测量仪定点监测尘埃微粒子数, 同时记录各时间段内人员流动的次数。结果 手术开始后15和60 min这2个时间段, 微粒子数出现2个高峰; 每个时间段内空气微粒子数与术中人员流动呈正相关(P<0.05)。结论 术中人员流动是影响空气洁净度的主要因素, 应尽量控制人员的流动。

Abstract:

Objective  The purpose of the study was to detect the air particle concentration of the dental implant surgery using local air laminar flow system in dynamic environment and to explore the related factors of its changes. Methods  The air samples were collected in a chosen dental implant surgery with local air laminar flow system on and 20 implantology cases were included. The air particle concentrations were detected by Handheld Particle Counter at every 15 minutes from the time point of 10 minutes after air purification to the end of the implant surgery. And the staff movement frequency was also recorded. Results  There were two peak particle concentrations at the time spot of 15 and 60 minutes after operation. And air particle concentration had a positive correlation with the staff movement frequency(P<0.05). Conclusion  The activity of staff movement has great impaction on the air cleanliness. Accordingly, effective management of staff reasonable work procedure is vital for infection control.

Key words: local air laminar flow system, staff movement, air cleanliness
