If you find that the gauze used to dress the chest incision has been soaked with ooze, you should inform the doctor in time. Sometimes patients and their family members may find clear fluid, bloody fluid or sticky “pus” coming out of the incision, please don’t worry, most of the cases are not infections, but just lymphatic fluid, small amount of blood leakage, fat liquefaction, etc. from the subcutaneous tissues. Generally, 7-9 days after surgery, before the patient is discharged from the hospital, the doctor will check the healing of your incision and remove the stitches. The 7-9 days after the surgery can only determine the initial healing of the incision and cannot ensure that there are no problems later. You will need to keep the incision gauze on for 2-3 days after you go home and it will be removed. If you are worried that the incision scab has not fallen off yet and has not healed, you can go to the nearest hospital to change the medication once every 2-3 days and continue to keep the incision and the surrounding skin clean and dry. If you sweat a lot, you need to go to the hospital to change the medication and gauze in time, and observe whether there is new redness around the incision, whether there is water, bleeding or pus, etc. Patients who have been postoperative for a long time may also experience the emergence of stitches in the tasty area. In these cases, there is no need to panic and you can contact your supervising physician or go directly to the hospital for examination. Do not treat the wound yourself to avoid increasing the risk of infection. If the wound scab has not fallen off yet, do not force it off, just wait for it to fall off naturally. If the incision is uncomfortable with the chest strap, you can wear a body shirt without buttons to reduce the direct friction between the chest strap and the incision.
