Abstract：Objective To explore the concentration and composition of harmful substances during laparoscopic cholecystectomy so as to provide evidence for elimination of surgical smoke.Methods The concentrations of carbon monoxide and carbon dioxide were detected at the beginning of cutting tissue,5 min,10 min,15 min and 20 min after cutting,at the end of the operation,1.5 m above the ground and 30 cm from the surgical incision.The concentrations of PM2.5 and PM10 within 10 seconds of the punch of the card.The organic components in the surgical smoke were detected by gas chromatography.Results Soon after cutting the tissue,the concentrations of CO and CO2 increased gradually with the extension of the operation.PM2.5 and PM10 increased rapidly in open stamp card valves,reaching the peak of (659.42±26.29) μg/m3 and (735.41±17.09) μg/m3 at the fourth second.We detected sevoflurane,cyclopentane,ethylbenzene,nonenal,styrene,cyclohexanone,2,2,4,4,6-pentamethyl heptane,2-ethyl hexanol,undecane,dodecane and other harmful substances in surgical smoke.Conclusion There are many harmful substances in surgical smoke,some of which exceed the standard of environmental protection.Long-term exposure will cause harm to the human body,and integrated protective measures need to be taken.
