After ankle surgery, the ankle can be sterilized locally with iodophor and covered with a sterile dressing. After ankle surgery, local dressing change will be carried out routinely, which is commonly used to disinfect with iodophor and then cover with sterile dressing. If the local incision is red, swollen, hot and painful, or even with secretion, broad-spectrum antibiotics should be applied along with local dressing change for anti-infection treatment. If the incision after surgery, long lasting, or even the emergence of a sinus tract continued to have secretion outflow, some patients also need to carry out local debridement vsd continuous negative pressure suction treatment. After the ankle surgery must be under the guidance of the doctor to carry out the appropriate treatment, do not do it on your own, so as not to cause infection and other adverse consequences.
