Why is an electrosurgical unit used in electrosurgery?

The unit sends energy through an active electrode chosen for the planned task. Depending on the setting and technique, the energy can heat, divide, dry, or coagulate tissue. This gives the clinician a way to work on a small area while limiting the treatment zone to the intended contact or energy field. Electrosurgery may be used for selected skin growths, bleeding points, or other superficial targets; the exact method depends on the diagnosis, location, size, and depth.

The device is not a diagnosis by itself. A clinician first decides whether electrosurgery is appropriate and whether tissue should be examined after removal.

Tell the treating clinician about implanted electrical devices, medicines that affect bleeding, allergies to dressings or antiseptics, and any history of slow wound healing. Follow the supplied wound-care instructions, keep the area clean as directed, and avoid picking at a crust while the surface repairs. Protect the healing skin from sun exposure according to the clinician’s advice, because irritation can make colour changes more noticeable.

Contact the clinic promptly if bleeding does not settle with the pressure instructions you were given, or if pain, swelling, warmth, redness, or drainage is increasing rather than easing. Seek urgent medical help for heavy bleeding, rapidly spreading swelling, breathing difficulty, or a severe allergic reaction. A persistent change at the treated site also deserves review.

Ask what the unit will be used to do, whether a sample will be sent for examination, how the wound should be dressed, and which changes should trigger a call. You can also ask how the treatment may affect pigment or scarring at your particular body site.
