Final answer:
Secondary intention healing refers to the process where a wound is allowed to heal from the edges inward, without surgical closure like suturing. This method is used when wounds are too large or infected to be closed immediately.
Step-by-step explanation:
When the surgeon says the patient's wound will be allowed to heal by secondary intention, this means the wound will be left open and allowed to heal from the edges inward. Unlike primary union, where the wound edges are brought together and possibly sutured or stapled to promote quicker healing, secondary intention healing involves the wound being left open.
It contracts and heals over time, filling in with new tissue and skin cells from the bottom and sides toward the surface. This method is utilized when the wound is too large or there is an infection that prevents primary closure.
