Probably you have asked yourself why it is essential to have abdominal drains for about a week after a tummy tuck. When a tummy tuck is performed, the fat layer is detached from the fascia that covers the muscle. The dissection is very extensive, requiring detachment of the bellybutton, and continues from the lower abdomen all the way to the upper abdomen. Anytime there is a potential space that is created during surgery—in other words, a space that was not there prior to surgery—the body reacts by filling this area with fluid. This fluid accumulates, causing inflammation and sometimes a seroma or a fluid cavity that can cause liposuction deformities and unsatisfactory results if not drained. Once the abdominal wall is tightened, two drains are placed in the mons area. These drains are placed from the lower abdomen all the way to the upper abdomen, and they are connected to a bulb that is compressed, allowing the fluid that will fill this cavity to be suctioned during the healing process. This prevents you from developing a fluid cavity that is going to negatively impact your new flat abdomen after surgery. These drains are easy to manage, and typically they are removed in about seven days. The amount of fluid drained every 24 hours needs to be recorded, because if you are draining too much, the drains might need to be kept for a longer period of time. Inserting drains after surgery is a must for a successful result with a tummy tuck. Applying basic surgical principles will allow the placement of the drains in the correct anatomical place for all the fluid to be removed during the first seven days after surgery.
