Changing a wound dressing at home

At a glance

Changing wound dressings at home after colorectal surgery is something most people manage successfully, even when it feels daunting at first. The key is preparation, a calm approach, and knowing what is normal versus what needs attention.

This guide covers the practical steps of a dressing change, what to have ready, and how to make the process as comfortable as possible. It applies to open wounds from procedures like fistulotomy, abscess drainage, hemorrhoidectomy, and pilonidal surgery — though your surgical team’s specific instructions always take priority.

Before you start

Gather your supplies

Having everything within reach before you begin makes the process smoother:

• Clean dressings — the type your surgical team recommended
• Saline solution or clean warm water — for dampening and gentle cleaning
• Gauze pads or soft cloths — for cleaning around the wound
• Disposal bag — for the used dressing
• Pain relief — if you find dressing changes uncomfortable, taking your pain medication 30 to 45 minutes beforehand can help
• Mirror — some people find a hand mirror helpful for wounds they cannot easily see
• Clean towel — to sit or lie on

Wash your hands thoroughly

This is the single most important step. Wash with soap and warm water for at least 20 seconds. If you have been given hand sanitiser, use it as well.

Choose your timing

Many people find dressing changes easiest:

• After a sitz bath or shower — the warm water softens any dried discharge and makes removal gentler
• After a bowel movement — so the fresh dressing stays clean longer
• When you are not rushed — giving yourself time reduces anxiety

The dressing change

Removing the old dressing

1. Wash your hands
2. Gently peel the dressing away from the skin — if it sticks, dampen it with warm water or saline and wait a minute
3. Look at the old dressing before disposing of it — noting the amount and colour of any discharge helps you track changes over time
4. Place the used dressing in your disposal bag

Cleaning the wound

1. Use saline or clean warm water on a gauze pad
2. Gently clean around the wound, wiping away from the wound edges rather than into them
3. Do not scrub — gentle dabbing or wiping is sufficient
4. Let the area air dry briefly or pat dry very gently with clean gauze

What to look at

While the wound is uncovered, take a moment to check:

• Colour — healthy healing tissue is pink or red. Dark, grey, or green tissue is worth reporting
• Discharge — some clear or slightly yellow discharge is normal. Thick, green, or foul-smelling discharge needs attention
• Swelling — some swelling is expected, but increasing redness or warmth spreading away from the wound is a concern
• Size — the wound should be gradually getting smaller over weeks

Applying the new dressing

1. Open the new dressing without touching the part that will contact the wound
2. Place it gently over the wound
3. Secure with tape or adhesive as needed — avoid pulling the skin taut
4. Make sure the dressing is comfortable and will stay in place with movement

Making it more comfortable

Dressing changes can be uncomfortable, especially in the early days. Strategies people find helpful:

• Take pain relief beforehand — timing it so it peaks during the change
• Do it after a warm bath — the tissue is softer and more relaxed
• Breathe slowly — tension makes everything feel worse
• Have someone help — a partner or family member can assist with hard-to-reach areas
• Use a non-adherent dressing — if your team has not specified a type, ask about dressings designed not to stick
• Keep a routine — the process gets easier and faster with practice

Wound packing

Some wounds — particularly after fistulotomy or abscess drainage — need to be packed with ribbon gauze or similar material. Wound packing is usually demonstrated by your surgical team or district nurse before you are expected to do it at home.

If you have been asked to pack the wound yourself:

• Follow the specific technique you were shown
• Pack gently — the material should fill the wound loosely, not be forced in tightly
• The amount of packing material will decrease as the wound gets smaller
• If you are unsure whether you are doing it correctly, ask for a follow-up demonstration

Tracking your healing

Keeping a simple record of each dressing change can be helpful:

• Date and time
• Amount and type of discharge
• Pain level
• Anything different from last time

This information is valuable at follow-up appointments and helps you notice gradual improvements that are hard to see day to day.

When to get help

Most wound healing after colorectal surgery is straightforward, but contact your surgical team if you notice:

• A sudden increase in pain that is not improving
• Heavy or persistent bleeding
• Discharge that becomes thick, green, or foul-smelling
• Increasing redness or warmth spreading from the wound
• Fever or feeling generally unwell
• The wound appearing to get larger rather than smaller

These signs do not always mean something is wrong, but they are worth checking.
