Childbirth lacerations are classified as grade III. Degree I lacerations refer to perineal skin and mucosal damage, degree II lacerations reach the perineal muscle layer, and degree III lacerations reach the anal sphincter. The healing time varies with the degree of laceration. For Ⅰ-Ⅱ degree laceration, it usually takes about five days to heal, and for Ⅲ degree laceration, it takes longer. In the conventional state, the suture technique, the neatness of the wound alignment, and the sutures are all factors that affect the healing of the wound. If the wound becomes infected or even needs to be re-sutured, healing can take longer, even up to one month. Precautions to promote wound healing include hygiene, frequent change of sanitary pads, wearing loose cotton underwear, high protein nutrition, physical methods such as infrared light, hot compresses, and keeping bowel movements open.
