WOUND HEALING

The process of healing is slow and goes through several stages. The first stage is called the inflammatory, resting or lag phase because it appears that very little is happening. In fact this is a very active phase. It lasts several days.

The second stage, during which time the body is producing collagen to strengthen the wound, is called the metabolic phase and lasts several weeks. At this time, the body produces stronger, thicker scars than are ultimately needed.

The final stage of healing is the remodelling phase. It is during this time that the body refashions the scar and decides how much will remain.

These three stage have significance for the patient During the phase of inflammation the scar is not strong. The wound becomes increasingly red. The redness lasts through the active or metabolic stage. It is easy to confuse with infection because the scar is so red.

The redness does not begin to fade for at least six weeks after the operation or injury. It is at this stage that the scar is strong. In youngsters and those with fair skin the redness is often very prolonged and can last months. Some patients form a persistently heavy scar called a keloid.

Many factors can affect wound healing including diabetes, vitamin deficiencies and smoking.

A wound is not fully healed for one to two years. It is rare to revise or re-do scars until they are completely mature.
