Not all early abortions require evacuation, but it depends mainly on whether there is intrauterine residue. If there is little vaginal bleeding and it lasts for a short time after abortion, there is usually no intrauterine residue and it does not need to be cleared. If there is a lot of vaginal bleeding and lasts longer than a week after miscarriage, or if there is abdominal pain, you should be alert to the presence of uterine residue and need to visit the hospital in time for clear diagnosis and treatment of uterine evacuation to avoid intrauterine infection and uterine adhesion. Early miscarriage refers to miscarriage within 12 weeks of gestation, mainly manifested as vaginal bleeding and lower abdominal pain after menopause. When incomplete miscarriage occurs, it can easily lead to poor uterine contraction, followed by hemorrhage or infection. Therefore, it is necessary to clarify whether there is residual uterine cavity, and if there is, the uterus should be cleared in time. It is also possible to prevent infection by applying antibiotics and medication to promote uterine contraction and to facilitate the discharge of uterine stasis. After early miscarriage, it is necessary to keep the perineum clean and dry, pay attention to personal hygiene, change sanitary napkins regularly to avoid secondary infection, and forbid bathing, intercourse and swimming within one month after miscarriage. One month after miscarriage, you need to review the recovery of the uterus, avoid strenuous activities, pay attention to rest, avoid overexertion, diet should be nutritious, can be appropriately supplemented with high-protein food, avoid eating spicy, cold food.
