During free TRAM flap procedure, you will have two "soaker catheters" placed by the surgeon directly into the surgical site. The catheters are flexible tubes which will allow pain medicine (or saline) to be delivered directly to the donor wound site which is the abdominal site from where the tissue for breast reconstruction is taken. A small pump (On-Q pump) will be connected to the catheter to deliver a constant flow of pain medicine (or saline) for up to 5 days. The On-Q pump is completely portable and can be attached to your hospital gown to allow for movement.
