The process of suture in normal delivery includes local anesthesia, searching for the starting point of the laceration, and suturing to stop bleeding. 1. Local anesthesia: During transvaginal delivery, the dilation of the perineum and vagina can lead to laceration and bleeding in the soft birth canal, which needs to be stitched up by a professional doctor to stop the bleeding, and the first step is to give local anesthesia to the site of the laceration. 2. Finding the starting point of the laceration: the starting point of the laceration should be found carefully, and the depth and extent of the laceration should be known, and the anatomical structure should be restored as much as possible. 3. Suture hemostasis: Starting at 0.5cm from the starting point of the laceration, suture hemostasis should be performed, and the tissues should be matched layer by layer. For deeper lacerations, care should be taken not to penetrate the rectal wall during suturing, and anal examination should be performed after suturing to ensure that the sutures have not penetrated the rectal wall. Sutures for perineal and vaginal wall lacerations after a normal delivery usually heal within 3-4 days, and the perineum is disinfected after delivery to keep the vulva clean and dry, and the sutures are removed in due course.
