What should you know about an Olympus electrosurgical unit?

An electrosurgical unit converts electrical energy into heat at a treatment tip. Depending on the setting and technique, a clinician may cut, coagulate, dry or destroy a small area of tissue. The device is used with compatible electrodes, cables and safety equipment; it is not itself a diagnosis or a treatment plan.

In dermatology, the technology may support [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/) or [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/). The exact method depends on the lesion, its location, its depth and whether tissue needs to be sent for examination.

Before treatment, mention pacemakers or implanted electrical devices, pregnancy, bleeding disorders, allergies to dressings or antiseptics, medicines that affect clotting, and any history of poor wound healing or raised scars. Ask whether the area needs a biopsy, local anaesthetic or a different procedure.

Afterward, keep the site clean and follow the dressing instructions. A small scab, tenderness or mild redness can occur. Avoid picking the crust and protect healed skin from sunlight to reduce lingering colour change. Do not apply household electrical devices to a treatment area.

Call the clinic if bleeding continues despite the advised pressure, pain is worsening, or redness spreads beyond the expected treatment area. Pus, increasing warmth, fever, a foul smell or wound separation can indicate infection or delayed healing. Seek urgent care for uncontrolled bleeding, breathing difficulty or a severe reaction after a medicine or dressing.

Ask what lesion or problem is being treated, why electrosurgery is suitable, whether a sample will be examined, which energy mode is planned, what scar or pigment changes are possible, and how to care for the wound.
