PATHOLOGY

Detailed explanation-1: -A surgical wound left open to heal by scar formation is a wound healed by secondary intention. In this type of wound, there is a loss of skin, and granulation tissue fills the area left open.

Detailed explanation-2: -Healing by first intention or Primary intention healing happens when the wound edges are approximated e.g. by sutures, staples or glue. Healing by second intention or Secondary intention healing takes place when the wound edges cannot be approximated and the wound needs to heal from the bottom.

Detailed explanation-3: -Secondary intention healing means a wound will be left open (rather than being stitched together) and left to heal by itself, filling in and closing up naturally. It will mean you need regular dressings to the area for up to six weeks, but the time to full healing depends on the size, depth and site of the wound.

Detailed explanation-4: -Two examples of common wounds treated with secondary intention are pressure sores and diabetic foot. Secondary intention requires a longer healing time and daily attention to treatment is necessarynecesssary. Dressings need to be applied in order to protect and keep the wound clean.
