Cavity wound during a national or regional emergency
Last edited: 27/08/2026
If you, or someone helping you, has been asked to change your dressing during a national or regional emergency, this leaflet will guide you through the process.
You will need:
- a clean surface
- non-sterile gauze squares
- packing material as prescribed, or in an emergency Aquacel®, Aquacel Ag® or a similar product
- an absorbent dressing as prescribed, or in an emergency an Allevyn Gentle Border®, Mepilex® or similar dressing
- forceps or, in an emergency, a cotton bud for packing the wound
- surgical tape.
If needed, dressings can be purchased from pharmacies or supermarkets.
How to change the dressing
- have a shower and remove the soiled dressing
- wash your hands with soap and water and dry them thoroughly using a clean towel or paper towel
- if the skin around the wound is still soiled or wet, gently clean the area using gauze
- lightly place the packing into the wound cavity, leaving a 2cm tail to help with removal. Use forceps or a cotton bud if needed
- cover with a foam dressing and secure with surgical tape if required
- wash your hands with soap and water and dry them thoroughly using a clean towel or paper towel.
How often should the dressing be changed?
Modern dressings are designed to remain in place for up to seven days.
Change the dressing if fluid reaches within 1cm of the edge of the dressing or if the dressing leaks.
- change the outer foam dressing
- only change the packing if it falls out and you are able to replace it safely without assistance.
Signs of infection
- increased pain
- increased leakage from the wound
- redness around the wound that spreads
- feeling unwell with flu-like symptoms.
Redness around the wound may be caused by wound fluid irritating the skin, similar to nappy rash. If this happens, change the dressing more often.
A combination of these symptoms may indicate an infection and you may need antibiotics.
Contact your GP if you are concerned.
Emergency planning
This leaflet has been developed for use during a national or regional emergency, when clinics, GP surgeries and hospitals may only be able to provide emergency care.
Emergency supplies
Dressings can be purchased from pharmacies or supermarkets.
Arrangements may be in place for pharmacies to provide emergency supplies until a prescription can be obtained once the emergency situation has ended.
