The time it takes for the granulation to grow flat is determined by the patient’s condition as well as the condition around the wound and the location of the wound. If the patient’s general condition is good, its healing is also good. If the patient’s nutritional condition is poor, i.e., the healing is slower. Wounds on the head and face heal fastest, wounds on the chest and abdomen heal second fastest, and wounds on the extremities heal slowest. If the general condition around the wound is good and the granulation tissue is fresh, its healing is also faster, whereas there are signs of infection, or necrotic material and fluid formation, in which case healing is slower. Generally the granulation tissue on the head and face takes 5 days to grow back, while the granulation tissue on the chest, back and abdomen takes 7-9 days to grow back, and the extremities take the longest, possibly 12-14 days. If the local granulation tissue is fresh, most wounds will heal completely within the prescribed time. If abscess or necrotic material is formed, this case should first remove the pus as well as inactivated tissue, repeated dressing changes, strengthen the local irrigation, can also be used hydrogen peroxide, iodine and saline, etc., after the granulation tissue is fresh, the date of growth may be generated in accordance with the original pattern, so that the patient usually needs half a month, or even a month to achieve clinical healing.
