Caring for a Surgical Wound at Home: Dressings, Showering and the Signs That Matter

Quick answer: Most surgical wounds are sent home under a dressing that is meant to stay on, not be changed daily. The job at home is to keep it dry and intact, leave it alone, and know the specific signs that mean infection. Modern waterproof dressings that stay on for several days are now common, and a 320 patient trial compared them directly with traditional gauze after hip and knee surgery.

Why the dressing is usually left alone

A closed surgical incision seals its surface within about 48 hours. After that the dressing is doing two jobs: protecting the wound from knocks and contamination, and managing whatever fluid leaks from it in the first few days. Every unnecessary dressing change exposes the wound, cools it, disturbs the new surface and introduces a chance of contamination. That is why the instruction is so often to leave it in place until the review appointment, even though most people's instinct is to check underneath.

Many hospitals now discharge patients with a waterproof film or a foam dressing with a border, designed to stay on for up to a week. Some of these absorb exudate and keep it away from the skin, so a small amount of staining under the dressing is expected rather than alarming.

What is being studied about post-operative dressings?

A relevant trial is registered as NCT06540040, a randomised study of 320 participants having hip and knee orthopaedic surgery. It compared advanced dressings, including a silver hydrofibre dressing, a transparent film and a bordered silicone foam, against traditional gauze based dressings. The registered primary outcome was the incidence of early surgical site complications at day 3, day 7 and day 14 after surgery, with the study also looking at patient comfort, pain, ease of application and exudate management. The registry lists the study as completed, with the study period running from August to December 2022.

Being honest about what the registry shows: no results are posted on the ClinicalTrials.gov record, so this is best described as what is being studied rather than what has been proven. The question it asks is the practical one for anyone recovering at home. Does a dressing that stays on and handles fluid better actually reduce early wound problems, or does it mainly improve comfort and convenience? Until results are posted, follow the dressing plan your surgical team gave you rather than switching to something you read about.

Keeping the wound dry, and showering

Ask before you assume. Some dressings are fully waterproof and you may shower normally. Others are not, and the usual advice is to cover the area or keep it out of the direct spray. General principles that apply either way:

• Shower rather than soak. No baths, pools, hot tubs or the sea until the wound is fully healed and you have been cleared.
• Pat the area dry gently rather than rubbing, and let it air for a few minutes before dressing.
• If a dressing gets soaked through or lifts at the edges, it is no longer doing its job and should be replaced rather than pressed back down.
• Do not apply creams, antiseptics, powders or oils to a healing incision unless you were told to.

What normal healing looks like

A little redness right along the incision line, mild swelling, bruising and some discomfort are expected in the first week or two. A small amount of clear or slightly blood stained fluid in the first few days is common. The wound may feel firm, lumpy or numb along its length for months, which is normal healing tissue and nerve recovery rather than a complication.

Signs that need review

• Redness that spreads outwards from the incision rather than staying as a thin line, particularly if it is warm to touch.
• Increasing rather than decreasing pain after the third or fourth day.
• Thick, cloudy, yellow, green or foul smelling discharge.
• The wound edges separating, or any gap opening in a closed incision.
• Fever, chills, or feeling generally unwell.
• In a hip or knee replacement, any wound that continues to leak beyond the first several days, which surgical teams take seriously because of the implant underneath.

Contact your surgical team or clinic rather than waiting for the scheduled appointment if any of these appear. Early surgical site infection is far easier to manage in the first days than in the second week.

Stitches, clips and glue

Dissolvable stitches do not need removing, though the ends may poke through and feel scratchy. Non dissolvable stitches and clips are usually removed around 7 to 14 days depending on the site, and that appointment matters, since clips left too long can leave marks. Surgical glue flakes off by itself over one to two weeks and should not be picked. Adhesive strips are best left to fall off on their own.

Moving, without pulling the wound

After joint surgery in particular, early movement is part of the treatment and not something to avoid out of concern for the wound. The balance is to follow the prescribed exercises while avoiding the specific movements that stretch across the incision, and to avoid heavy lifting until cleared. If a dressing repeatedly lifts or rolls with movement, tell the team rather than taping over it, because a dressing that suits your activity level exists.

An important note

This article is general information, not medical advice. Surgical wounds differ by operation, by closure method and by your own risk factors such as diabetes, smoking and medications. Please follow the instructions from the team that performed your surgery, and consult your doctor or a wound care nurse about your own wound.
