Chemical composition of smoke produced by high-frequency electrosurgery

Area of Science:

• Environmental Health
• Occupational Safety
• Analytical Chemistry

Background:

• Surgical smoke generated during electrosurgery poses potential health risks to operating theatre personnel.
• Quantification of toxic compounds in surgical smoke is crucial for understanding these risks.
• Particular interest was placed on toluene, ethylbenzene, and xylene due to their suspected carcinogenic properties.

Purpose of the Study:

• To quantify toxic compounds, specifically toluene, ethylbenzene, and xylene, present in surgical smoke.
• To assess the potential health and safety implications for surgical staff.
• To differentiate compound concentrations based on tissue type ablated.

Main Methods:

• Surgical smoke samples were collected from various procedures using charcoal tubes.
• Gas chromatography coupled with mass spectrometry was employed for sample analysis.
• Quantification of specific volatile organic compounds was performed.

Main Results:

• Electrosurgery involving adipose tissue thermal decomposition yielded higher aldehyde concentrations and lower toluene levels.
• Epidermal tissue ablation generated surgical smoke with elevated concentrations of toluene, ethylbenzene, and xylene.
• The study confirmed the presence of irritant, carcinogenic, and neurotoxic compounds.

Conclusions:

• Electrosurgical smoke contains compounds with irritant, carcinogenic, and neurotoxic potential.
• Exposure to these compounds presents significant health risks for individuals in surgical settings.
• Findings underscore the need for enhanced health and safety protocols in surgical practice.
