Using the Abscess Model for Incision and Drainage. The completed abscess model is ready for incision and drainage. A) A scalpel is used to incise the simulated abscess of the abdominal wall, which leads to realistic drainage of the abscess contents. B) Hemostats and a culture swab are used to sample the interior of the abscess cavity. C) A simulated abscess cavity of the lower leg is filled with wound packing material to complete the incision and drainage procedure.
