Abstract Background: The composition and concentration distribution of volatile organic compounds (VOCs) in surgical smoke had seldom reported. This study aimed to investigate the profile of VOCs and their concentration in surgical smoke from breast surgery during electrocautery in different tissues, electrosurgical units, and electrocautery powers.Methods: Thirty-eight surgical smoke samples from 23 patients performed breast surgery were collected using evacuated stainless steel canisters. The concentrations of 87 VOCs in surgical smoke samples were analyzed by gas chromatography-mass spectrometry. The human tissues, electrosurgical units, and electrocautery power were recorded.Results: The median level of total VOCs concentrations in surgical smoke samples from mammary glands (total VOCs: 9,953.5 ppb; benzene: 222.7 ppb; 1,3-butadiene: 856.2 ppb; vinyl chloride: 3.1 ppb) using conventional electrosurgical knives were significantly higher than that from other tissues (total VOCs: 365.7–4,266.8 ppb, P < 0.05; benzene: 26.4–112 ppb, P < 0.05; 1,3-butadiene: 15.6–384 ppb, P < 0.05; vinyl chloride: 0.6–1.9 ppb, P < 0.05). A high methanol concentration was found in surgical smoke generated during breast surgery (736.7–4,304.6 ppb) using different electrosurgical units. An electrocautery power of ≥27.5 watts used for skin tissues produced a higher VOCs concentration (2,905.8 ppb).Conclusions: The surgical smoke samples collected from mammary glands using conventional electrosurgical knives had high VOCs concentrations. The carcinogens (including benzene, 1,3-butadiene, and vinyl chloride) and methanol were found in the surgical smoke samples from different electrosurgical units. The type of electrosurgical unit and electrocautery power used affected VOCs concentrations in surgical smoke.
