Incision and Drainage
Incision and drainage and 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, a pointed scalpel or a lancet. This allows the pus fluid 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 PICC line to enable readiness of treatment for possible septic shock.
What is an abscess?
An abscess is a collection of pus surrounded by a wall of tissue. An abscess happens when your body tries to control infection. It causes a painful lump and can make you feel unwell. You should no longer have the abscess and should be free of pain. Surgery should prevent the serious complications that an abscess can cause.
