Usually women can have their stitches removed about 4-5 days after the stitches are torn in normal labor and heal in about 7-14 days depending on their individual body conditions, but full recovery takes about 30 days. After a woman enters the second stage of labor, the perineal tear may be caused by perineal edema, inflammation, too tight perineum, too low pubic arch, huge baby or too fast delivery of the baby during the crowning of the fetal head. Because of the rich neurovascularity of the vaginal laceration area in women, it heals easily if the suturing technique is good and usually takes 7-14 days. However, the wound should be closely monitored for redness, swelling, hardness and abnormal discharge after suturing. In addition, during the healing process, you need to pay attention to the cleanliness and hygiene of the vulva, you can use potassium permanganate sitz bath, local topical iodophor to prevent postoperative infection, regular rest and rest, prevent constipation, and at the same time after the removal of stitches must pay attention to not squatting for a long time to prevent the wound from splitting.
