Wound Check After Surgery: Infection

Your surgical wound has become infected. Infection after surgery usually involves just the top layers of skin. Sometimes the infection is deeper in the wound and may involve a collection of fluid or pus. Treatment will depend on the type of infection you have.

Once antibiotic treatment is started, the area of redness should not increase. Pain should start to decrease after 2 days of treatment.

Home care

Different types of surgery require different types of care and dressing changes. It is important to follow all instructions and advice from your surgeon, as well as other members of your healthcare team.

Wound care

  • Keep the wound clean, as directed by your healthcare provider.

  • Change the dressing as directed. Change the dressing sooner if it becomes wet or stained with blood or fluid from the wound.

  • Bathe with a sponge (no shower or tub baths) for the first few days after surgery, or until there is no more drainage from the wound. Unless you received different instructions from your surgeon, you can then shower. Do not soak the area in water (no baths or swimming) until the tape, sutures, or staples are removed and any wound opening has dried out and healed.

Changing the dressing

  • Wash your hands before changing the dressings.

  • Carefully remove the dressing and tape; don’t just yank it off. If it sticks to the wound, you may need to wet it a little to remove it, unless your healthcare provider told you not to wet it.

  • Wash your hands again before putting on a new, clean dressing.

  • Gently clean the wound with clean water (or saline) using gauze or a clean washcloth. Do not rub it or pick at it.

  • Do not use soap, alcohol, hydrogen peroxide, or any other cleanser.

  • If you were told to dry the wound before putting on a new dressing, gently pat it dry. Do not rub.

  • Throw out the old dressing. Do not reuse it!

  • Wash your hands again when you are done.

Types of dressings

Your healthcare team will tell you what type of dressing to put on your wound. Follow your healthcare team’s instructions carefully, and contact them if you have any questions. Two common types of dressings are described below. You may have one of these or another type.

  • Dry dressing. Use dry gauze. If the wound is still draining, use a “nonadherent” dressing, which shouldn’t stick to the wound.

  • Wet-to-dry dressing. Wet the gauze, and squeeze out the excess water (or saline), before putting it on. Then, cover this with a dry pad.

Medicines

  • If you were given antibiotics, take them until they are used up or your healthcare provider tells you to stop. It is important to finish the antibiotics even though you feel better, to make sure the infection has cleared.

  • You can take acetaminophen or ibuprofen for pain, unless you were given a different pain medicine to use. (Note: If you have chronic liver or kidney disease, or have ever had a stomach ulcer or gastrointestinal bleeding, or are taking blood thinner medicines, talk with your healthcare provider before using these medicines.)

  • Aspirin should never be used in anyone under 18 years of age who is ill with a fever. It may cause severe liver damage.

Follow-up care

Follow up with your healthcare provider, or as advised, for your next wound check or removal of your sutures, staples, or tape.

  • If a culture was done, you will be notified if the results will affect your treatment. You can call as directed for the results.

  • If imaging tests, such as X-rays, an ultrasound, or CT scan were done, they will be reviewed by a specialist. You will be notified of the results, especially if they affect treatment.
