Drain (surgery)

A surgical drain is a tube used to remove pus, blood or other fluids from a wound. Drains inserted after surgery do not result in faster wound healing or prevent infection but are sometimes necessary to drain body fluid which may accumulate and in itself become a focus of infection. The routine use of drains for surgical procedures is diminishing. Better radiological investigation and confidence in surgical technique have reduced their necessity. It is felt now that drains may hinder recovery by acting as an 'anchor' limiting mobility post surgery and the drain itself may allow infection into the wound. In certain situations their use is unavoidable.

Drains may be hooked to wall suction, a portable suction device, or they may be left to drain naturally. Accurate recording of the volume of drainage as well as the contents is vital to ensure proper healing and monitor for excessive bleeding. Depending on the amount of drainage, a patient may have the drain in place 1 day to weeks. Signs of new infection or copious amounts of drainage should be reported to the health care provider immediately. Drains will have protective dressings that will need to be changed daily/as needed.
