Surgical wound liquefaction is the localized fat liquefaction of the wound, which can generally be relieved by adequate drainage, infrared irradiation and prevention of wound infection. 1. Adequate drainage: When liquefaction occurs in surgical wounds, sutures can be removed appropriately, and the incision can be repeatedly flushed with saline to eliminate the fat emulsified tissue as much as possible, and gauze and drainage strips can be filled in to drain the wound if necessary, and the incision area can be kept dry and clean, and the medication can be changed on a regular basis. 2. Infrared irradiation: when the surgical wound liquefaction, after treatment, can be combined with infrared irradiation, to promote inflammation and eliminate granulomatous edema, promote the growth of granulation, and effectively reduce wound wound wound exudate. 3. Prevent wound infection: If necessary, do a bacterial culture check on the liquefied fat, and if it is clear that the causative organisms, we should actively apply antibiotics to prevent infection. It is recommended to go to the hospital in time, under the guidance of the doctor, according to the condition of targeted treatment, to avoid delaying the condition, causing other damage.
