Drains are placed after surgery to remove fluid or air from the operative area, preventing collections such as seromas or hematomas that can impede healing and increase infection risk. They also provide a way to monitor how the wound is healing through the drainage they collect.

Care focuses on keeping the drain system closed and intact, so pathogens cannot enter and the drain functions properly. This means ensuring all connections are secure, tubing remains patent (not kinked or pulled), and the collection container or canister is maintained in the proper position and kept clean. Regularly check and document the drainage: measure the amount, and note the color and consistency (for example, serous, serosanguinous, or bloody). Observe the skin around the entry site for signs of irritation or infection, and keep the surrounding dressing clean and dry.

Removal timing is guided by the surgeon. The drain is kept in place until drainage decreases to a minimal and stable level and the area shows adequate healing, as determined by the surgeon's plan. Removing a drain too early can lead to fluid reaccumulation; leaving it in too long can increase infection risk and skin irritation. Always follow specific orders for emptying, documenting, and when to remove, and alert the surgeon if there are sudden changes in drainage, foul odor, increased redness, or fever.
