Cesarean section wound fat liquefaction needs to be combined with the healing of the incision and the amount of exudate to choose the treatment, if the exudate is small, can be placed locally in saline gauze drainage; exudate is more, the incision does not heal, need to open the incision in time. If necessary, antibiotics can be given to prevent infection as prescribed by the doctor. Fatty liquefaction of cesarean section wounds is mostly seen in obese people, for women with fatty liquefaction of cesarean section wounds, if the exudate is less and the incision only partially heals poorly, you can cut 1~2 sutures and place saline gauze to drain the wound. If there is more exudate and the incision is not healing, the incision needs to be opened in time to drain adequately and place wet compresses with gentamicin saline gauze, and then suture when the granulation tissue is fresh to shorten the healing time. Oral or IV antibiotics are given during treatment to prevent infection, such as azithromycin and ceftazidime. For patients with cesarean section wound fat liquefaction, they should cooperate with the doctor to choose the appropriate way of treatment according to their personal situation. Pay attention to rest and avoid exertion during treatment.
