Your surgeon's postoperative instructions should guide this, because dressings vary depending on the incision, drains, and whether there are any small open areas. For a routine tummy tuck incision, many patients keep 4x4 inch sterile gauze pads at home for small areas, plus larger abdominal pads or nonstick dressings if more coverage is needed. If you have drains, you may also need small split gauze pads or regular 4x4 gauze folded around the drain sites. Paper tape, gentle surgical tape, or the tape your surgeon recommends can be useful, but avoid placing strong adhesive directly on irritated skin. Before buying a large amount, ask your surgeon's office what they prefer and how often they want you to change the dressing. If you notice increasing redness, drainage, odor, fever, worsening pain, or separation of the incision, contact your surgeon promptly rather than just changing the dressing more often.
