Abstract:
Objective:To explore the effect of fixed continuous negative pressure suction on the smoke concentration in the Operating Room when the surgical field was exposed during open surgery in the laminar flow operating room.Methods:From July to December 2019, convenience sampling was used to select 120 cases of rectal mucosal circumcision performed in the Operating Room of Hangzhou Red Cross Hospital. Cases were randomly divided into control group ( n=60) and observation group ( n=60) . Both groups all used the laminar flow negative pressure suction system in the Operating Room. Control group carried out conventional negative pressure suction by the surgical assistant. In observation group, a fixed smoke suction device was used to implement continuous negative pressure suction at a position 5 cm beside the surgical incision and 10 cm in height. The changes in the concentration of particles (PM 3.0) with a size ≤3.0 μm (PM 3.0) in electrosurgical smoke from 3 sampling points at the vertical height of 10, 20, and 40 cm of the surgical incision were compared between the two groups. Results:When the electrosurgery was used continuously for 3 to 5 s, the PM 3.0 concentration of electrosurgery smoke from sampling points at 10, 20, and 40 cm in observation group was (5 802.03±2 268.36) μg/m 3, (3 487.98±1 807.94) μg/m 3 and (3 224.28±2 022.35) μg/m 3 respectively, all lower than those in control group, the difference was statistically significant ( t=9.735, 11.886, 5.634; P<0.01) . After stopping using the electrocautery for 5 minutes, the PM 3.0 concentration of electrocautery smoke at 3 sampling points in observation group was lower than those in control group, and the differences were statistically significant ( P<0.05) . Conclusions:When using high-frequency electrosurgical surgery in open surgery, the implementation of fixed continuous negative pressure suction in the exposed surgical field can effectively attract electrosurgical smoke and reduce the concentration of electrosurgical smoke in the operating area of the laminar flow operating room.
