What should you know about a BOWA electrosurgical unit?

The unit is equipment used by a trained clinician, not a diagnosis or a treatment that you operate yourself. Depending on the handpiece, setting, and procedure, electrical energy can heat, separate, or seal tissue. In dermatology, this may be relevant when a clinician removes a superficial growth, treats a bleeding point, or combines scraping with cautery. The clinician selects the technique according to the lesion, its location, and the need for laboratory assessment.

The device may be discussed alongside [Electrosurgical Unit](/technology/electrosurgical-unit/) information or procedures such as [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/) and [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/). The equipment name alone does not establish which procedure you need.

Before treatment, tell the clinic about implanted electronic devices, pregnancy, allergies to local anaesthetic or dressings, medicines that affect bleeding, and any condition that affects wound healing. Ask whether tissue will be sent for examination and how the treated area should be protected.

Afterward, follow the wound-care instructions: keep the area clean as directed, avoid picking a scab, and protect healing skin from sun exposure. Mild tenderness, redness, or a small amount of oozing can occur after a skin procedure, but the expected pattern depends on the technique and body site.

Contact the treating clinic if bleeding does not settle with firm, continuous pressure, if pain is worsening rather than easing, or if redness spreads around the wound. Fever, increasing warmth, swelling, pus, or a wound that is opening also warrants prompt medical advice. Seek urgent help for heavy bleeding, faintness, trouble breathing, or a rapidly developing allergic reaction.

Ask: What procedure will the unit support? Why is this technique suitable for my lesion? Will you use local anaesthetic? Could treatment affect pigment, hair, or scarring at this site? Will the tissue be examined? What dressing and activity instructions should I follow, and who should I contact if the wound changes?
