Penrosedrän

Penrosedræn is a Danish term that translates to "Penrose drain" in English. It refers to a type of surgical drain used in medical procedures to remove excess fluid, such as blood, pus, or other secretions, from a surgical site. The drain is named after Sir Roger Penrose, a British mathematician and physicist, though the connection to his work is primarily through the characteristic shape of the drain, which often resembles a Penrose tiling or a spiral.

The Penrose drain is typically made of soft, flexible latex or silicone. It is a thin, flat, hollow tube that is inserted into the wound cavity. The drain is left open at one end, allowing fluid to flow out passively, and the other end is typically connected to a collection device or simply brought out through the skin. Its flat, flattened shape is designed to prevent kinking and to provide a larger surface area for drainage compared to a round tube. This design helps to reduce the risk of blockage and ensures efficient fluid removal, which is crucial for wound healing and preventing infection.

Penrose drains are commonly used in various surgical specialties, including general surgery, orthopedic surgery, and plastic surgery. They are particularly useful in situations where there is a risk of accumulating fluid that could impede healing or lead to complications. The drain is usually removed once the drainage decreases to a minimal amount, typically a few days after surgery. The removal process is generally simple and can be done by a healthcare professional with minimal discomfort to the patient.
