【 摘 要 】

Abstract：Objective To explore the the effective protection distance of electrosurgical smoke in the operating theatre. Methods 〓Totally 150 patients undergoing thyroid or breast surgeries under elective general anesthesia were included and randomly divided into a non-aspirator group(group C), an aspirator attraction 300 mmHg group(group S1), and an aspirator attraction 500 mmHg group(group S2), with 50 cases in each group. At the same time, 50 surgical surgeons were selected to measure the PM2.5 values at 10, 20, 30, and 40 cm vertical distances of the electric knife head in real time, 5 min and 10 min after the high-frequency knife was used. In addition, the straight-line distance from the surgeon's nose to the electric cutter head during the procedure was measured. Results 〓With the increase of measurement distance, the PM2.5 value was significantly reduced(χ2=148.824,χ2=137.016,χ2=145.296,P<0.01). The PM2.5 values of group S1 and group S2 were significantly lower than that of group C at 10, 20, 30, and 40 cm vertical distances(P<0.05), and the PM2.5 value of group S2 were lower than that the S1 group at 10, 20, 30, and 40 cm vertical distances(P<0.05). The straight line distance from the surgeon's nose to the electric cutter head was not significantly different between male and female doctors(P>0.05). Conclusion 〓In the class 100 laminar flow purification operating theatre, using of power 500 mmHg attraction and keeping surgeons from the tip of electric knife more than 30 cm, can effectively prevent the harm of electrosurgical smoke.
