What should you know about a KLS Martin electrosurgical unit?

An electrosurgical unit sends energy through a handpiece to produce a carefully selected tissue effect. Depending on the setting and electrode, the clinician may cut, coagulate, or dry a small area. It is equipment used by the treating professional, not a treatment that patients operate themselves.

In dermatology, the device may support removal of a selected lesion, treatment of superficial blood vessels, or control of bleeding after curettage. The procedure, rather than the brand name alone, determines what you should expect. Read about Electrosurgical Unit, Electrosurgery, or Curettage And Cautery for context.

Tell the clinician about a pacemaker or implanted electrical device, pregnancy, medicines that affect bleeding, allergies to dressings, and any skin infection near the treatment site. Ask whether the area will be numbed and how it will be dressed. Afterward, keep the site clean and follow the specific wound-care instructions; do not remove a scab or apply an unapproved product.

A treated spot can be tender or crusted while it heals. Protecting it from friction and sun can help reduce irritation and later colour change.

Contact the clinic if bleeding does not settle with the advised pressure, or if pain, redness, warmth, swelling, drainage, or fever is increasing rather than improving. Seek urgent help for breathing difficulty, faintness, or a rapidly spreading reaction after treatment.

Ask what is being treated, why electrosurgery is appropriate, how the wound will heal, whether a sample will be sent for assessment, and which changes should trigger a review.
