What is the primary application of CO2 laser in surgery?

The primary application of the CO2 laser in surgery is for plastic surgery and dermatologic procedures, specifically for the removal of tattoos, skin lesions, and for resurfacing the skin. The CO2 laser emits a wavelength of light that is highly absorbed by water, which makes it effective for cutting and vaporizing soft tissue with minimal damage to surrounding structures. This precision allows surgeons to perform delicate procedures, such as removing blemishes or tattoos, while promoting quicker healing and reduced scarring, which is particularly valuable in cosmetic surgery.

In contrast, other options do not align with the fundamental use of CO2 lasers. For instance, cardiovascular procedures typically require specific techniques and tools that differ from those appropriate for laser treatments. Bone surgery and orthopedic procedures generally rely on different methods and instruments tailored for hard tissue manipulation. General anesthesia administration is unrelated to the laser's function, as lasers are used for cutting or ablating tissue rather than for anesthesia itself. Thus, the effectiveness and applications of CO2 lasers in enhancing cosmetic outcomes position them as a primary tool in plastic and dermatologic surgery.
