Wound healing
Which dressing to recommend will depend on the nature of the wound. However, the general approach to optimising healing is by supporting a moist, but not wet, healing environment.
Healing follows a four-stage process:1,2
- Coagulation (<3 hrs) – bleeding stops, platelets form clot and growth factors start to be released.
- Inflammatory phase (0-3 days) – inflammatory cells are attracted to the site, with leukocytes and macrophages cleaning up the wound, and fibroblasts attracted to start the rebuilding process.
- Proliferative phase (3-21 days) – new blood vessels and granulation tissue forms with fibroblasts, myofibroblasts and keratinocytes active.
- Maturation and remodelling (three weeks - two years) – epithelialisation takes place with new skin cells emerging and collagen fibres or scar tissues reorganised, and the scar tissue strengthens.

Reflection
What first aid actions would you normally recommend for minor wounds, cuts abrasions or burns? Which dressings do you recommend and why? How do you decide which first aid products to stock and how do you merchandise them in your pharmacy?
Planning
How can you familiarise yourself with the range of dressings suitable for minor injuries? What resources are available?
Action
In addition to reading this article, what other activities will you do? Do you or your staff need to go on a first aid training course? Is it time to review your first aid at work policy?
Evaluation
How will you put your learning into practice? Review the first aid products you stock, whether they are the best selection for your patients, and whether you and your staff can offer the best supporting advice.
