Incision and drainage (I&D), also known as clinical lancing, are minor surgical procedures to release pus or pressure built up under the skin, such as from an abscess, boil, or infected paranasal sinus. It is performed by treating the area with an antiseptic, such as iodine-based solution, and then making a small incision to puncture the skin using a sterile instrument such as a sharp needle or a pointed scalpel. This allows the pus to escape by draining out through the incision.
Good medical practice for large abdominal abscesses requires insertion of a drainage tube, preceded by insertion of a peripherally inserted central catheter line to enable readiness of treatment for possible septic shock.
