What should you know about a ConMed diathermy machine?

The device sends controlled high-frequency electrical energy through an active instrument. Depending on the selected mode and tip, the clinician can divide tissue, seal small blood vessels, or destroy a superficial lesion. A return electrode may be used with some settings so the electrical pathway is controlled. The machine is equipment; it does not diagnose a skin growth or decide whether treatment is appropriate.

In dermatology, electrosurgery may be considered for selected benign lesions, unwanted tissue, or bleeding control. The treatment name, depth, and aftercare depend on the lesion and the clinician’s examination. For example, some genital warts may be treated with electrosurgery, but treatment choice is individual.

Tell the clinician about implanted electrical devices, metal in the body, medicines that affect bleeding, allergies, pregnancy, and any tendency to form thick scars. Do not shave, pick, or apply irritants to the treatment area unless instructed. Afterward, follow the wound-care plan: keep the area clean, avoid rubbing, and use only recommended ointment or dressing. A crust can form as the treated surface heals; do not pull it away.

Ask which instrument and energy setting will be used, whether a sample will be sent for testing, and how long healing may take. Electrosurgery is different from an ordinary warming treatment; it uses energy at a selected site under clinical control.

Contact the treating clinic if bleeding does not settle with firm, continuous pressure, or if pain, swelling, redness, warmth, or drainage is increasing rather than improving. Seek urgent help for heavy bleeding, faintness, breathing difficulty, or a rapidly spreading reaction. A fever with a worsening wound also needs prompt medical advice.

Which lesion or problem is being treated, and why is electrosurgery suitable? What will I feel during the procedure? Will I need local anaesthetic? What wound changes are expected, and when should the area be reviewed? Could the treatment affect hair, pigment, or scarring in this location?
