Wound dehiscence after lateral incision needs to be cleaned and changed, and a second suture is needed if necessary. After delivery, for those with perineal lateral incision sutures, perineal disinfection should be carried out daily, and the incision should also be observed for redness, swelling, hardness and secretion. When the perineal lateral incision is opened, the wound should be thoroughly cleared of secretions and necrotic tissue, filled with oil gauze, and regularly changed, and generally healed, but when the wound is fully opened, a second suture can be used when fresh tissue grows out of the wound. Mothers should pay attention to proper rest after delivery, eat more protein-rich food, such as meat, fish, eggs, etc. to promote physical recovery and wound healing, to ensure that the vulva is clean and dry, and change the underwear frequently, when there is perineal wound pain and increased secretion, we should go to the hospital in a timely manner.
