Late pregnancy belly persistent pain all the time may be the state of labor, but also may be the aura of uterine rupture, preterm labor, placental abruption and other pathological factors caused by the need for immediate medical attention, fetal preservation treatment or cesarean section treatment, the specific causes and treatment methods are as follows: 1, the state of labor: late pregnancy full-term pregnancy when labor is imminent, the most typical symptom is the emergence of regular abdominal pain, paroxysmal. Intermittent pain symptoms disappear and the pain level gradually increases, which is a normal manifestation of late pregnancy; 2. Placental abruption: it is a common cause of pathological belly pain in late pregnancy, which is manifested as tear-like pain in the lower abdomen, mostly accompanied by vaginal bleeding. The main symptoms are sudden onset of persistent abdominal pain, lumbago and abdominal and back pain, and the degree of abdominal pain is proportional to the area of placental abruption and the amount of blood accumulation behind the placenta. At this time, the patient should end the labor as soon as possible and take uterine contraction drugs after delivery, such as uterine contractions, prostaglandin preparations, etc. to strengthen contractions and prevent postpartum hemorrhage; 3. Pre-eclampsia uterine rupture: after some pregnant women are in labor, due to fetal malposition, cephalopelvic disproportion or other reasons leading to poor progress of labor, compulsory uterine contractions can occur, which can easily lead to uterine rupture. Before rupture occurs, there will be severe and persistent pain in the lower abdomen with obvious pressure pain. Once it is clear that the signs of a precursory uterine rupture are present, medication should be used immediately to suppress contractions and surgical treatment should be performed as soon as possible to prevent uterine rupture. In case of uterine rupture, anti-shock treatment and cesarean section should be carried out immediately, and the uterus should be repaired or removed according to the situation during the operation; 4. Premature labor with aura: Premature labor may be caused by factors such as excessive fatigue, abdominal trauma, or fetal dysplasia, intrauterine hypoxia, and excessive amniotic fluid in late pregnancy, and continuous pain in the stomach may occur before preterm labor occurs. Pregnant women with preterm labor can take oral nifedipine, indomethacin and other contraction inhibitors to properly control contractions and prolong the pregnancy to win the time for fetal lung maturation treatment and intrauterine transfer.
