What is a potential hazard related to the use of lasers during surgery?

• A. Exposure to aerosols and gases
• B. Exposure to loud noise
• C. Exposure to radioactivity
• D. Exposure to toxic substances

Answer: (A)

Lasers used in surgery can create a hazardous plume as tissue is vaporized, releasing aerosols and gases into the operating room. This plume may contain biologically active particles such as bacteria, viruses, and cellular debris, along with volatile chemicals. Inhalation or contact with mucous membranes can pose health risks to staff and patients, including respiratory irritation and potential pathogen transmission. Because this aerosol and gas exposure is the primary safety concern with laser use, it’s the best answer.

Loud noise is not a primary hazard of laser surgery, and lasers do not emit ionizing radiation, so exposure to radioactivity isn’t a typical concern. While toxic substances can be present in the plume, the central exposure risk is the aerosols and gases generated during ablation, which is why that option best fits the scenario. To mitigate risks, use smoke evacuation with appropriate filtration, and ensure proper PPE and laser-specific eyewear are in place.
