What are wound drainage systems?

Wound drainage systems allow exudate to drain from the wound into a collection device.

- They can be open or closed.

- Examples of open drainage include:

- Wound drains: These are tubes inserted into the wound that allow the fluid to drain into a collection bag.

- Pressure dressings: These apply a constant, low-level of pressure to the wound, which helps to push the exudate out.

- Closed drainage systems may utilize the following mechanisms:

- Gravity drainage: This involves inserting a drainage tube into the wound and allowing the exudate to flow out by gravity.

- Suction drainage: This uses a suction pump to remove the exudate from the wound.

Closed wound drainage systems reduce the risk of infection and facilitate healing by:

- Keeping the wound clean and free of debris: The drainage system prevents exudate from building up in the wound, which can provide a breeding ground for bacteria.

- Reducing swelling: The drainage system helps to reduce swelling by removing excess fluid from the wound.

- Promoting healing: The drainage system can help to promote healing by creating a moist environment that is conducive to cell growth.
