There is no way to avoid umbilical cord torsion during pregnancy. Umbilical cord torsion is because the umbilical cord connects the umbilical cord of the fetus to the placenta and the fetus moves around in the uterus, causing the umbilical cord to twist in a spiral shape. Normal umbilical cord torsion of 6-11 weeks will not cause umbilical vascular atresia, which affects the oxygen supply to the fetus. However, if the umbilical cord is excessively twisted, it will affect the umbilical cord blood, causing intrauterine oxygen deprivation to the fetus, and serious interruption of blood flow will cause fetal death in utero and other adverse consequences. Pregnant women cannot change or correct umbilical cord torsion during pregnancy, but they need to count the fetal movements regularly to detect abnormal fetal movements and early warnings of intrauterine distress, so as to rescue the fetus from oxygen deprivation in a timely manner. Meanwhile, ultrasound monitoring can detect the blood flow resistance of the umbilical cord blood vessels, which further indirectly detects intrauterine distress of the fetus. If abnormalities are detected, immediate medical attention should be sought.
