Surgical drains are medical devices used to remove fluids that accumulate in a surgical site after an operation. They help prevent complications such as infections or fluid buildup, which can hinder healing. Drains can be temporary and are usually placed during surgery, exiting the body through a small incision. There are different types of surgical drains, including Jackson-Pratt drains and Penrose drains. Each type has a specific design and function, but all aim to promote healing by allowing excess fluid to escape. Proper care and monitoring of surgical drains are essential for a successful recovery.
