Dressing Change

A dressing change is a wound care procedure in which a nurse or doctor removes an old wound covering, cleans the wound, and applies a fresh dressing (protective covering) to support healing and prevent infection.

When a wound is left open to the air or covered by a dirty or soaked dressing, bacteria can enter and slow or stop the healing process. During a dressing change, the care team clears away dead tissue, excess fluid (called exudate), and any material that has built up on the wound surface. A new dressing is then chosen to keep the wound moist enough to heal, protect it from outside contamination, and — where needed — deliver medication directly to the wound bed.

Dressing changes are used whenever a wound needs regular cleaning and protection during the healing process. The type of wound and the amount of fluid it produces will determine how often the dressing must be changed — sometimes daily, sometimes every few days.

• Surgical wounds after an operation, including incisions (cuts made by a surgeon) that are healing normally or have opened slightly
• Traumatic wounds such as cuts, lacerations (jagged tears in the skin), or abrasions (skin scraped away) from accidents
• Pressure injuries (also called bedsores or pressure ulcers) — areas of damaged skin caused by prolonged pressure on the body
• Diabetic foot ulcers — open sores on the feet that heal slowly due to poor blood supply and nerve damage from diabetes
• Burns, from minor scalds to more serious partial-thickness burns
• Infected wounds that require antiseptic cleaning and antimicrobial (infection-fighting) dressings
• Wounds healing by secondary intention — wounds left open on purpose to close gradually from the inside out
• Post-procedure wounds after biopsies (tissue sampling), drain removal, or catheter (thin tube) insertion sites

There are situations where a standard dressing change is not the most appropriate step, and the care team will adapt the plan accordingly.

• Very deep or heavily infected wounds may need surgical debridement (removal of dead tissue in an operating theatre) before dressing changes can be effective
• Wounds with signs of serious spreading infection (redness extending widely, fever, foul smell) require medical treatment first, not just a dressing change
• Some wound types — such as certain skin grafts — require specialised dressings that must not be disturbed for several days; the timing is decided by the surgeon

A dressing change is generally a low-risk procedure, but because it involves an open wound, there are recognised complications to be aware of.

• Pain or discomfort during removal of the old dressing, especially if it has dried and adhered to the wound surface
• Bleeding — a small amount is common when the dressing is removed or the wound is cleaned; significant bleeding is uncommon
• Wound infection (signs include increasing redness, warmth, swelling, pain, or pus) — this can happen if the wound is not cleaned thoroughly or if sterile technique is not maintained
• Skin irritation or allergic reaction to adhesive (sticky) dressing materials or cleaning solutions
• Wound disruption — in some cases, removing a dressing too forcefully can disturb fragile new tissue that has started to form
• Psychological distress — seeing one's own wound can cause anxiety or distress, particularly for patients with large or complex wounds

For most routine dressing changes, there is no need to fast or stop regular medications. However, if the wound is complex or if the procedure is expected to be painful, the care team may recommend a mild pain reliever beforehand — the specific choice and timing will be decided by the clinician. Patients taking blood thinners should tell their nurse or doctor in advance, as these can increase the risk of minor bleeding when the wound is cleaned.

Smoking slows wound healing by reducing blood supply to the skin, and the care team will usually advise patients to avoid smoking as much as possible during the healing period. Alcohol can also affect healing and may interact with wound medications, so moderation is generally recommended.

Before or during the first assessment, the care team may carry out some checks to guide the dressing plan:

• Visual assessment of the wound — size, depth, colour, and the amount and type of fluid it is producing
• A wound swab (a gentle wipe with a small sterile cotton tip) to identify any bacteria present, if infection is suspected
• Blood tests to check for signs of infection or conditions such as diabetes or poor nutrition that affect healing
• Imaging such as ultrasound (USG) if a deep infection or pocket of fluid beneath the wound is suspected

The dressing change itself typically follows these steps, though the exact sequence may vary depending on the wound type and hospital protocol:

• 1. The patient is positioned comfortably so the wound is fully accessible.
• 2. The care provider washes their hands thoroughly and puts on sterile (germ-free) gloves.
• 3. The old dressing is gently loosened — sometimes moistened with saline (salt water) to reduce pain — and removed.
• 4. The wound and the surrounding skin are inspected carefully.
• 5. The wound is cleaned with a suitable solution, usually saline or an antiseptic (germ-killing) wash, using gentle strokes to remove debris and old fluid.
• 6. If needed, dead or loose tissue is carefully trimmed — a process called debridement.
• 7. A new dressing appropriate to the wound's current stage of healing is selected and applied.
• 8. The dressing is secured with tape or a bandage, and the patient is told what to watch for before the next change.

After each dressing change, recovery in the immediate sense is minimal — most patients can return to their normal activities right away, unless the wound itself limits movement. The broader aftercare focus is on protecting the wound, supporting healing between changes, and recognising early warning signs that need medical attention.

• Keep the dressing dry and intact until the next scheduled change; avoid submerging the wound in water (baths, pools, or the sea) unless the care team has approved a waterproof dressing
• Avoid pressing on, scratching, or picking at the wound or the dressing
• Eat a balanced diet with adequate protein and vitamins — nutrition plays a direct role in how quickly wound tissue rebuilds itself
• Stay as well-hydrated as possible, as good hydration supports skin repair
• Follow the schedule for return visits exactly — skipping a dressing change can allow bacteria to multiply and the wound to deteriorate
• Watch for warning signs and contact the care team promptly if the wound becomes more painful, the surrounding skin becomes redder or warmer, there is an increase in fluid or the fluid smells bad, the wound edges begin to separate, or the patient develops a fever
• Avoid smoking during the healing period, as smoking significantly delays wound closure
• If sutures (stitches), staples, or drains are present, the care team will advise on when and how these will be removed — do not attempt to remove them at home
• Once the wound has fully healed, the care team may advise on scar care, such as moisturising or sun protection, depending on the wound's location and depth
