Babies born with umbilical cord torsion may be free of abnormalities, or stillbirths and neonatal ischemic-hypoxic encephalopathy may occur. 1. No abnormality: Umbilical cord torsion is mostly a normal physiological phenomenon. Fetal activity can make the normal umbilical cord twist along the longitudinal axis, and physiological torsion can be up to 6 to 11 weeks, which does not affect the oxygen supply of the fetus, and the baby born is mostly free of abnormality. 2. Stillbirth: due to excessive twisting of the umbilical cord causing severe intrauterine oxygen deprivation, intrauterine death occurs before delivery, at this time, labor should be induced in a timely manner, so as to avoid the occurrence of serious disorders of maternal coagulation function. 3. Neonatal ischemic-hypoxic encephalopathy: due to excessive twisting of the umbilical cord, resulting in intrauterine hypoxia of the fetus, insufficient oxygen supply to the brain tissue, and ischemic-hypoxic encephalopathy after birth. At present, it is mainly treated by neurotrophic drugs and hyperbaric oxygen. Severe neonatal hypoxic-ischemic encephalopathy will leave some sequelae, such as cerebral palsy. It is recommended that women during pregnancy should have regular checkups to observe the condition of the fetus in the uterus, and in the second trimester, they can also count the fetal movements to know the condition of the fetus. If there is any discomfort, women should consult a doctor for appropriate treatment under the guidance of a medical professional.
