What should you know about an electrosurgical cautery machine?

A clinician chooses an electrode and an energy setting suited to the target. Heat can destroy a small unwanted growth, control minor bleeding, or separate tissue. The machine is equipment; electrosurgery is the procedure performed with it. Local anaesthetic may be used when the treated area is sensitive or the work is deeper. The treated site can form a crust while it heals, and the final appearance depends on the lesion, depth, location, and your skin response.

Tell the clinician about a pacemaker or implanted electronic device, medicines that affect bleeding, allergies to antiseptics or anaesthetic, and any history of raised scars. Follow the wound-care instructions, keep the area clean, avoid picking a crust, and protect healing skin from strong sun. Do not apply cosmetic products or active creams to an open site unless advised. A follow-up may be useful if the lesion needs assessment after treatment.

Contact the treating clinic if pain, warmth, swelling, redness, or discharge is increasing rather than settling, or if the wound opens. Seek prompt medical help for heavy bleeding, spreading redness, fever, facial swelling, or trouble breathing. A changing, bleeding, or repeatedly returning growth also needs clinical assessment because cautery does not replace diagnosis.

Ask what is being treated, whether tissue will be sent for testing, which electrode and anaesthetic are planned, how long healing may take, and what change should trigger a review.
