Cauterization for a nosebleed

A clinician first identifies the bleeding area, often on the front part of the nasal septum. A local anaesthetic may be used to reduce sensation, followed by a chemical or heat method applied to the vessel. The aim is to create a small seal so the vessel is less likely to reopen. Cauterization is not suitable when the bleeding source cannot be seen or when another problem needs treatment. Dry air, nose picking, forceful blowing, infection, allergies, and some medicines can contribute to recurrent bleeding; hypertension may also need review.

For an active bleed, sit upright, lean forward, and pinch the soft part of the nose continuously while breathing through your mouth. After cauterization, follow the clinician’s instructions about ointment or saline moisture. Avoid picking, forceful nose blowing, heavy exertion, and very hot drinks for the advised period. Keep the room comfortably humid and discuss medicines that affect clotting before the procedure. Treating Allergic Rhinitis, a Common Cold, or Sinusitis may reduce irritation when one of these is contributing.

Get urgent help if bleeding is heavy, continues despite firm pressure, follows a significant injury, causes faintness or breathing difficulty, or occurs with unusual bruising. Repeated episodes, bleeding from both nostrils, or a nosebleed with poorly controlled blood pressure warrants medical review.
