Open Wounds

SIGNS AND PHASES OF WOUND HEALING

When an injury occurs, your body naturally goes into overlapping healing phases known as Hemostasis, Inflammation, Proliferation, and Maturation. Simply put:
Phase 1: HEMOSTASIS is the process of the wound closing by blood clotting, occurring at the point of injury as your body acts to stop the bleeding.^2a
Phase 2: INFLAMMATION, which is often marked by swelling, redness and heat at the wound site, continues to control the bleeding and prevent infection right after injury.^2b
Phase 3: PROLIFERATION involves the formation of new tissue, usually pink or red in colour, as the new skin starts to build.^2c
Phase 4: MATURATION is when new skin becomes stronger – often marked by stretching or puckering around the wound, when the new tissue takes hold and the wound becomes fully closed.^2d

Acute versus chronic wounds

How your wound heals largely depends on whether it is acute or chronic. It is widely accepted that any wound that goes through the phases of healing within 4 weeks is an acute wound³. A wound that fails to heal within 4 weeks is chronic.
However, there are major differences between the two that can only be distinguished by taking a closer look at the wound at a cellular level.4 How your wound heals depends on wound type, severity and wound care treatment.

FACTORS THAT MAY DELAY CHRONIC WOUND HEALING:

Age – if you are over 60
Wound characteristics such as size and shape
Infection – when pathogens such as bacteria enter the wound site
Chronic diseases such as diabetes or diseases that affect the circulatory system
Poor nutrition particularly in a chronically ill or elderly patient
Dehydration – a lack of moisture at the wound’s surface
Poor blood circulation – blood is critical for transporting nutrients to tissue for wound healing
Excessive edema (fluid retention causing body tissues to swell), which results in poorer blood circulation to the injured area
Reinjured wounds can delay and can even stop wound healing
Lifestyle choices such as smoking and too much alcohol⁵

WHEN TREATING MINOR WOUNDS:

Then, to prevent infection, remove all dirt and debris by rinsing the wound gently with cool, clean water⁷
If the wound is bleeding, take a clean absorbent material such as a washcloth, towel or bandage and apply pressure until the bleeding stops^6b
Apply petroleum jelly or wound spray for faster healing^8a
Depending on the nature of the wound, cover it with a sterile bandage to help prevent the wound from reopening, and keep it covered until it heals6c
Change the bandage once day or if it becomes wet or dirty^8b
First wash your hands with soap and water^6a

When to seek medical care

Even though most wounds are minor and treatable at home, you should seek immediate medical care if:

Your wound bleeds excessively
Does not stop bleeding after immediate pressure
Becomes infected
Is deeper than half an inch
You have a fever
A lump in your armpit or groin^9c

The most common complication is risk of infection so take care to monitor your wound for signs of increased drainage, warmth or swelling, pus or a foul odour.^9b Whether your wound is minor or more serious it is important to take quick action.^9c

Promote faster wound healing

Leads to faster than expected new tissue formation, even in deep wounds where bone is exposed.¹⁰

Protect wounds while they heal
Helps to keep wounds free from infection and lowers the chance that a dressing will stick to a wound.^11-14

Reduce pain and simplify dressing changes
Associated with reduced pain, including pain due to burns efficient dressing changes and less need for wound cleansing.^10-14
