Wound drainage is a medical procedure used to remove excess fluid that accumulates in a wound or surgical site. This fluid can be a result of inflammation, infection, or the body's natural healing process. By draining this fluid, healthcare providers can help prevent complications such as infection and promote faster healing. There are different types of drainage systems, including suction drains and gravity drains. These systems allow for continuous or intermittent removal of fluid, depending on the patient's needs. Proper management of wound drainage is essential for effective recovery and minimizing the risk of further complications.
