Surgical Drain Care: Why They Are Used and Home Maintenance

During and after surgery, the body generates fluid (serum and lymph) as an inflammatory response to the procedure. If this fluid is allowed to collect in the “dead space” created by the operation, it can lead to several complications:

• Seromas and Hematomas: Collections of clear fluid (seromas) or blood (hematomas) that can put pressure on incisions and cause pain [1].
• Infection Risk: Stagnant fluid serves as a breeding ground for bacteria. Drains move this fluid out of the body, significantly lowering the risk of abscesses [2].
• Tissue Adhesion: By removing fluid, drains allow the skin and underlying tissues to stay in close contact, which is vital for proper healing in reconstructive and cosmetic surgeries [2].

Your surgeon will select a drain based on the specific procedure and the expected volume of fluid.

1. Jackson-Pratt (JP) Drain

The JP drain is the most common type used in breast and abdominal surgeries. It consists of a flexible tube connected to a lemon-sized, silicone bulb. When compressed, the bulb creates constant low-level suction to pull fluid out [1].

2. Hemovac Drain

Similar to the JP drain but designed for larger volumes of fluid, the Hemovac uses a circular, spring-loaded container. It is frequently used in orthopedic surgeries, such as hip or knee replacements, and can hold up to 500 mL of fluid [1].

3. Penrose Drain

Unlike the JP or Hemovac, the Penrose drain is an “open” system that relies on gravity rather than suction. It is a soft, flat latex tube that allows fluid to soak directly into a gauze bandage [6].

Caring for a drain requires a disciplined routine. Patients on community forums like Reddit often emphasize that keeping a dedicated “drain log” is the best way to ensure they are removed on schedule.

Emptying the Reservoir (Closed Systems)

You should empty your JP or Hemovac drain when it is half full or at least 2–3 times daily [5].

1. Sanitize: Wash your hands thoroughly with soap and water.

2. Unblock: Open the plug at the top of the bulb/container.

3. Measure: Pour the fluid into a measuring cup. Note the color (e.g., bright red, pink, or straw-colored) and the amount in milliliters (cc).

4. Re-activate Suction: Squeeze the bulb until it is flat, then replace the plug. The bulb must stay compressed to continue pulling fluid [1].

“Stripping” or “Milking” the Tubing

Fluid can sometimes contain small clots or fibrin that block the tube. Stripping the tube prevents these clogs.

• Hold the tubing near the skin with one hand to prevent pulling.

• With the other hand, use your thumb and forefinger to pinch the tube and slide them down toward the bulb, pushing any vertical blockages into the reservoir [5].

• Using an alcohol wipe on the outside of the tube can help your fingers slide more easily [2].

Cleaning the Site

Gently wash the skin around the insertion site once a day with mild soap and water. If you have an open Penrose drain, you must change the gauze dressing whenever it becomes saturated [6].

While minor discomfort is normal, certain symptoms require immediate contact with your surgical team. Understanding these signs is as important as understanding surgical errors and hospital safety protocols.

• Sudden Stoppage: If a drain that was producing 50 mL a day suddenly produces zero, the tube may be clogged or dislodged [1].
• Signs of Infection: Watch for a fever over 100.4°F (38°C), foul-smelling discharge, or increased redness and warmth at the site [6].
• Color Changes: Fluid typically transitions from dark red to pink to pale yellow. If fluid returns to a bright red “bloody” appearance after being clear, it may indicate internal bleeding [1].

Drains are typically removed in the office once output drops below a specific threshold—usually less than 30 mL in a 24-hour period for two consecutive days [2]. The removal process is quick; the surgeon snips the single suture holding the tube in place and gently slides it out. While patients often fear this step, most describe it as a strange “sliding” sensation rather than sharp pain [1].

The Goal: Surgical drains prevent fluid buildup (seromas/hematomas) and reduce infection risk by removing inflammatory fluids from the surgical site.

Action Plan:

• Log Everything: Record the time, color, and volume of drainage every time you empty the bulb.

• Maintain Suction: Ensure the bulb is squeezed flat after emptying; a round bulb is not pulling fluid.

• Strategic Dressing: Wear loose clothing or use safety pins to clip the bulbs to your clothes to prevent the tubes from snagging or pulling on your skin.

• Hygiene First: Always wash hands before handling the drain or the entry site.

Final Thought: Although they are often the most frustrating part of postoperative life, surgical drains are temporary. Diligent care for 1–2 weeks ensures the underlying tissues heal securely, protecting the long-term results of your surgery.
