After delivery, if a woman has had a lateral episiotomy suture, itching may occur at the site of the suture wound. First of all, we should observe whether the suture site is red, swollen, congested, and has abnormal discharge? If there is no such phenomenon, it may be a manifestation of the wound to heal. In the process of healing, fibrous scar tissue is formed, which will form the itching phenomenon in women. In addition, women have a certain amount of malodor and vaginal discharge after delivery, which can also stimulate itching in the wound area. At this time, wash the vulva with water or use chlorhexidine metronidazole lotion daily to prevent the occurrence of infection. If you find congestion, redness, swelling, or even yellow, purulent discharge at the site of the suture, it may be caused by infection. In this case, iodophor can be used to disinfect and squeeze out the pus completely. Sometimes oral antibiotics, such as levofloxacin or cephalosporin, are also required for treatment.
