Surgical Drain

A closed-suction drain removes blood, serous fluid, or other postoperative fluid from a surgical site into a sealed reservoir. This reduces fluid accumulation, which can place pressure on tissue, separate wound edges, impair healing, or provide a medium for infection. Jackson-Pratt and Hemovac drains are commonly used because their reservoirs create controlled negative pressure without leaving the wound open to the environment. The surgeon selects the drain according to the operative site and the volume of fluid expected. The reservoir must remain compressed to maintain suction. Drainage often changes from blood-tinged or serosanguineous fluid toward a smaller amount of clearer, serous fluid as healing progresses. The trend matters more than one isolated measurement: a sudden return to bright-red drainage, a rapid increase, or an unexpected change in consistency can signal a complication. Drain care is performed within the RPN’s authorized scope, competence, employer policy, and prescriber orders. The RPN assesses, performs established care safely, documents the findings, and escalates findings that require RN, prescriber, or surgical review rather than independently extending their authority.
