The healing time of a laceration varies depending on the degree and size of the laceration and the physical condition of the mother. The healing time of perineal lacerations during labor varies from person to person and from injury to injury. Under normal circumstances, the laceration will heal initially in about 7-9 days and completely in about two weeks after suturing. If the laceration is severe and irregular, it will take longer to heal due to the larger size or difficulty of the suture. If the mother has conditions such as diabetes or scarred skin, the healing time will be longer, but most will heal within a month. If the wound does not heal for a long time, and there are symptoms such as redness, swelling, heat and pain, you need to go to the obstetrics department of the hospital in time for disinfection, dressing change and other treatments to avoid inflammation and suppuration of the wound. After delivery, women should pay attention to the perineum’s cleanliness and hygiene, wash the vulva in time after bowel movement, and use 1:5000 potassium permanganate solution for scrubbing every day to promote blood circulation and disinfect and sterilize the wound to accelerate the healing process.
