If the patient needs surgery due to foot trauma, or some kind of foot disease, after foot surgery, the affected limb must be elevated appropriately, and the height should be higher than the patient’s heart level, which can speed up the return of blood from the foot to the heart, which can effectively eliminate the edema that occurs after foot surgery, and is also conducive to the swelling and wound healing. Patients are advised to elevate the affected limb and to avoid moving down to the ground, which may cause local swelling and congestion in the wound and may be detrimental to wound healing. At the same time must apply antibiotics after surgery, anti-infection treatment, can be through oral cefradine capsules or amoxicillin capsules, etc. to control infection, can also be directly intravenous infusion of ceftriaxone sodium, or clindamycin, etc. to anti-infection treatment, when the infection is controlled, the wound will heal quickly.
