Sterilization of the uterus after a normal birth is not uncommon and usually not necessary. Women do not need to sterilize the uterus after a normal delivery, and the uterus exists in the pelvis, so if the uterus is to be cleaned, it can only be accessed from the endocervix to the uterine cavity. As the mother’s body is weaker after a normal delivery, the uterus and vagina are more sensitive, in the uterine disinfection may aggravate the pain of the pregnant woman, or cause damage to the cervix and so on, therefore, it is not necessary to do uterine sterilization after a normal delivery. For women who have had a normal delivery, they should pay attention to the disinfection of the perineal tear or lateral incision, and use a clean medical swab dipped in iodine to apply it locally, so as not to cause wound infection, and should also pay attention to personal hygiene, keep the perineal area clean and dry, and during the puerperal period, they should be diligent in replacing sanitary napkins, change and wash underwear, pay attention to the cleanliness of the private parts after urinating and defecating and, in case of any abnormality, promptly consult the doctor for medical consultation and treatment, and so on.
