It is felt now that<unk>  may hinder recovery by acting as an 'anchor' limiting mobility post surgery and the<unk> itself may allow infection into the wound. In certain situations their use is unavoidable.<unk>  may be hooked to wall suction, a portable suction device, or they may be left to<unk> naturally. Accurate recording of the volume of<unk> ge as well as the contents is vital to ensure proper healing and monitor for excessive bleeding.
