What should you know about an electrosurgery unit?

An electrosurgery unit usually combines a generator, controls, cables, a handpiece, and interchangeable electrodes. The clinician selects a technique based on the tissue and intended result. A fine electrode can focus treatment, while a broader contact arrangement can support coagulation. The unit may be used in surgical dermatology for carefully selected lesions and procedures, including treatment of Genital Warts in appropriate cases.

The device does not replace diagnosis. A new, changing, bleeding, or uncertain growth may need a clinical examination and sometimes a sample before treatment. The clinician also considers the body site, depth, skin type, medical history, and possibility of scarring or colour change.

Give a complete list of medicines and mention implanted electronic devices, bleeding tendencies, allergies, pregnancy when relevant, and previous problems with wound healing or anaesthetic. Follow instructions about washing the area and stopping products. During treatment, local anaesthetic may be offered. Afterwards, clean the site as directed, keep hands away from any crust, and protect healing skin from friction and strong sunlight. Do not use antiseptics or antibiotic creams unless the treating team recommends them.

Ask the clinic for advice if pain becomes stronger, bleeding continues, redness spreads, swelling increases, or the wound develops warmth, cloudy fluid, or an unpleasant smell. Urgent assessment is appropriate for heavy bleeding, fainting, breathing difficulty, or a rapidly spreading reaction. Keep the procedure instructions because the expected appearance differs between treatment sites.

Ask which electrode and mode are planned, whether the area will be numbed, whether tissue will be sent for assessment, and how the unit is adapted to your medical history. Confirm the cleaning routine, likely healing changes, sun protection, activity limits, and the symptoms that should prompt a review.
