The postpartum lateral incision wound can heal within a week with careful care, and can be fully recovered in 3-4 weeks’ time. The lateral incision is an oblique incision made by the doctor in the perineum during the woman’s normal delivery, which is re-sutured after the delivery is over. It is more difficult to repair this wound because the woman will have a tear in the perineum during normal labor and delivery. Not all women who have a normal delivery need to have a lateral incision. The doctor will choose the lateral incision according to the woman’s condition and the condition of the fetus. Lateral incision in normal labor can quickly reduce the resistance of the soft birth canal, speed up the birth also can prevent perineal tears and protect the pelvic floor muscles of the mother, which will form the lateral incision wound after delivery. As long as the wound is well cared for after surgery, change the medication on time and avoid wound infection, it can heal in about a week after surgery. Therefore, postpartum care is particularly important. First of all, we should drink more water, urinate more often, and eat a light and nutritious diet; we should change sanitary napkins regularly to keep the vulva clean to prevent infection and change medicine regularly; we should move as early as possible after delivery, walk on the ground in time, and pay attention not to push too hard when we defecate to prevent the wound from tearing; at the same time, we should prohibit sexual life within six weeks after delivery. Therefore, in order to make the wound recover faster and better, we must pay attention to avoid infection and do a good job of care.
