Post-Surgical Wound Care & Dressings: A Practical Guide

A practical guide for post-surgical wound care: the tray features medical scissors, folded gauze, a gauze roll, and a perforated fabric bandage, dressing, all neatly arranged on a white surface.

Wound care plays a crucial role in healing after surgery. Using the right dressing and following proper care instructions can prevent infections, reduce pain, and promote faster recovery. This guide is designed for patients, nurses, and doctors to help with choosing the right dressing, managing wound issues, and knowing when to seek help.


1. Choosing the Right Dressing for a Healing Surgical Wound

For non-infected wounds that have been closed with sutures or staples, the ideal dressing should:

βœ” Protect the wound from friction and infection
βœ” Maintain a moist environment to speed up healing
βœ” Be easy to remove without damaging new skin

Common Types of Dressings

πŸ’‘ Your doctor or nurse will choose the best option based on wound type and healing stage.

Dressing TypeExamplesBest For
Non-adherent dressingsTelfa, AdapticPreventing sticking to the wound, reducing pain when changing dressings
Transparent film dressingsTegaderm, OpsiteWaterproof protection, easy monitoring of the wound
Foam dressingsMepilex, AllevynAbsorbing excess fluid while keeping the wound moist
Hydrocolloid dressingsDuoderm, ComfeelHelping wounds heal by maintaining moisture and removing dead tissue

    2. What If You Have a Skin Reaction to Dressings?

    Some patients develop contact dermatitis due to the adhesive in wound dressings. If you notice redness, itching, irritation, or rash, take these steps:

    πŸ”Ή Remove the dressing and wash the area with mild soap and water
    πŸ”Ή Apply a mild corticosteroid cream (e.g., hydrocortisone)
    πŸ”Ή Switch to a hypoallergenic or silicone-based dressing


    3. Understanding Hydrocolloid Dressings: When & How to Use Them

    Hydrocolloid dressings, such as Duoderm or Comfeel, help wounds heal by:

    βœ” Forming a gel that absorbs wound fluid
    βœ” Creating a protective barrier against bacteria
    βœ” Encouraging natural removal of dead tissue (autolytic debridement)

    πŸ”΄ Possible downsides:

    • Maceration (overhydration of the skin) if the wound is too wet
    • Odour from the gel formation (which is normal and not a sign of infection)
    • Difficult removal, especially on delicate skin

    4. Is a Smelly Wound Always an Infection?

    A patient may return 5 days after surgery, worried about an odor under a hydrocolloid dressing. If the wound looks clean and a swab shows no bacterial growth, reassure the patient:

    🟒 The odor comes from the hydrocolloid gel interacting with wound fluid.
    🟒 It is normal unless there are other infection signs (redness, swelling, pus, fever).

    πŸ’‘ What to do:

    βœ… Remove the dressing, clean the wound with saline, and apply a new one
    βœ… Educate the patient on signs of infection and when to seek medical attention
    βœ… Offer a follow-up appointment if concerns persist


    5. Should Wounds Be Kept Dry or Moist?

    Many believe keeping wounds dry helps healing, but moist wound healing is actually better! Studies show:

    βœ” Moist wounds heal faster with less scarring
    βœ” Keeping wounds too wet (excess fluid) can lead to skin breakdown but not necessarily infection

    πŸ’‘ Proper dressing choice ensures the right moisture balance for healing.


    6. Should You Use Antibiotic Ointments on a Surgical Wound?

    ❌ Routine use of antibacterial ointments (like Neomycin, Polysporin) is not recommended because:

    🚫 Risk of allergic reaction (contact dermatitis)
    🚫 Potential for antibiotic resistance
    🚫 No added benefit over simple petroleum jelly (Vaseline)

    βœ… Better alternatives:
    πŸ”Ή Use petroleum jelly to maintain moisture
    πŸ”Ή Try silicone-based dressings for hydration and scar prevention
    πŸ”Ή Only use antibiotic ointments if there is an infection


    7. Managing Post-Surgical Bleeding (Oozing Wounds)

    A 78-year-old patient returns 4 hours post-surgery with a soaked dressing from oozing. What should be done?

    Possible Causes of Bleeding:

    πŸ”Ή Gravity & blood flow in lower legs can prolong oozing
    πŸ”Ή Blood thinners or age-related fragile skin may contribute

    Management Steps:

    1️⃣ Remove the soaked dressing and check for active bleeding
    2️⃣ Apply firm pressure with sterile gauze for 10–15 minutes
    3️⃣ If bleeding continues:
    βœ” Use a haemostatic agent (e.g., silver nitrate)
    βœ” Apply a pressure dressing (elastic bandage over gauze)
    βœ” Elevate the limb above heart level to slow blood flow
    4️⃣ If bleeding persists, assess for clotting issues or suture failure


    8. Benefits of Occlusive (Non-Breathable) Dressings

    Some dressings are non-breathable, creating an occlusive environment that speeds up healing.

    How Do They Help?

    βœ… Keep wounds moist, helping new skin cells migrate faster
    βœ… Reduce bacteria contamination by forming a protective seal
    βœ… Minimise scab formation, which slows down healing
    βœ… Encourage autolytic debridement, removing dead tissue naturally

    How the Body Responds to Occlusive Dressings

    πŸ”Ή Increased hydration β†’ Cells grow faster
    πŸ”Ή Lower oxygen tension β†’ Promotes new blood vessel growth (angiogenesis)
    πŸ”Ή Stable temperature β†’ Optimises enzyme activity in healing


    Key Takeaways for Patients, Nurses & Doctors

    βœ” Choose the right dressing based on wound type and healing stage
    βœ” Watch for signs of infection but don’t mistake normal dressing changes (e.g., hydrocolloid odor) for problems
    βœ” Avoid unnecessary antibiotic ointmentsβ€”simple petroleum jelly works just as well
    βœ” Moist wound healing is best for faster recovery and minimal scarring
    βœ” Control post-op bleeding with direct pressure, elevation, and careful monitoring
