A local anaesthetic is used to numb a small part of your body It is used to prevent or relieve pain, but will not put you to sleep. Sometimes local anaesthetics are uncomfortable, so a light sedation may be given to make the procedure less unpleasant. Local anaesthetic with sedation is a less risky alternative (if appropriate) to having a general anaesthetic. A drip will be put into a vein in your hand or forearm. A mild sedative drug is injected into a vein to induce a ‘sleepy like’ state. It makes you feel very relaxed during the procedure. You may remember some or a little about what has happened during the procedure.
