If a mild perineal laceration occurs during childbirth, it can usually heal within 7 days after being stitched up by a doctor. But if the laceration is more serious, reaching the second degree or third degree perineal laceration, it is more serious, and the healing is also slower, and it is easy to cause infection. But if it is a third degree perineal fissure, you must take oral anti-inflammatory drugs. Within 3 days after childbirth, you should eat a slag-free diet and use an open cork when you first relieve your bowels, without exerting excessive force to avoid affecting the healing of the wound. Wash the perineum twice a day and pay attention to preventing infection.
