Whether surgical drains are necessary after breast implant surgery, for either cosmetic augmentation or reconstruction, does not have a simple answer. The decision to place drains is highly variable, depending on the procedure, the patient’s anatomy, and the surgeon’s technique. Drains are small, flexible tubes temporarily placed near the surgical site to manage the body’s natural response to the procedure. While they are standard in many complex breast operations, they are increasingly optional or avoided in less extensive surgeries.
Why Drains Are Used After Breast Surgery
The body naturally responds to surgery by producing fluid in the newly created space around the implant, a process known as extravasation. This fluid is a mixture of blood and lymph that collects in the implant pocket. Surgical drains, typically closed-suction systems, are inserted to actively remove this excess fluid from the surgical site.
If this fluid accumulates, it can lead to complications such as seroma or hematoma. A seroma is a collection of clear, yellowish fluid that causes swelling, discomfort, and a misshapen outcome. A hematoma is a collection of blood, which may require surgical evacuation if it is large or expanding.
By creating a pathway for fluid exit, drains minimize the space where these collections can form, aiding the healing process. Removing the fluid helps surrounding tissues re-adhere to each other and the implant. This reduces tension on the incision lines and decreases post-operative pain. Active drainage also helps maintain the implant’s intended position and shape, contributing to a smoother recovery.
When Are Drains Most Likely Necessary?
The necessity of drains correlates strongly with the extent and type of surgery performed. Drains are nearly routine in complex breast procedures, such as mastectomy and breast reconstruction. This is especially true for procedures involving tissue expanders or autologous (flap) tissue transfers. These surgeries involve more tissue dissection and a larger surgical area, leading to greater fluid production.
In contrast, drains are far less common, and often avoided entirely, in standard cosmetic breast augmentation. This remains a point of surgeon-specific technique. Some surgeons use drains for one or two days post-augmentation to reduce the risk of fluid collection. Others rely on meticulous surgical technique and post-operative compression to manage fluid, as studies do not show a clear consensus on the benefit of routine drain use.
The placement of the implant also influences the decision. Submuscular (under the chest muscle) placement tends to generate more post-operative fluid than subglandular (over the muscle) placement. Dissecting the pectoralis muscle causes trauma to the muscle fibers, which increases inflammation and fluid output, making drains more likely. In reconstructive cases, factors like the use of Acellular Dermal Matrix (ADM), older age, and larger implant size are associated with increased drainage volume and longer drain placement.
Managing Drains During Recovery
If drains are placed, the patient is responsible for their care at home, involving regular monitoring and maintenance. The most common type is the closed-suction drain, consisting of a flexible tube secured to the skin and connected to a compressible bulb reservoir. The bulb must be compressed after emptying to create a vacuum, which generates the suction needed to pull fluid from the surgical site.
Patients typically need to empty the bulbs two to four times a day, or whenever they are half-full. They must carefully measure and record the volume of fluid collected. It is also important to “strip” or “milk” the tube multiple times daily by gently squeezing and sliding fingers down the tubing. This clears any clogs or thickened fluid, ensuring the tube remains functional and maintains optimal drainage.
The drains typically remain in place for a few days to a few weeks, with removal criteria depending on the fluid output volume. Most surgeons require the drain output to be consistently low, often less than 20 to 50 cubic centimeters (cc) over a 24-hour period. This low output must be maintained for one or two consecutive days before removal. The removal itself is a quick procedure, performed by a nurse or surgeon, involving removing the single stitch holding the tube and gently sliding the tube out.
Patients should keep the drain insertion site clean and dry and monitor for warning signs of complication. A sudden, significant increase in drainage volume, fluid becoming thick or cloudy, or developing a foul odor should be reported immediately. Signs of infection, such as fever, increasing pain, or significant redness around the drain site, also require prompt medical attention.
