Whether the breech position can be turned over at 32 weeks of pregnancy is mainly related to the size of the fetus, the amount of amniotic fluid and other factors. If the fetus is small, with more amniotic fluid and more space in the uterine cavity, the breech position may turn to the head position. If the pregnant woman is not found to have the umbilical cord wrapped around her neck after ultrasound examination, she can try to change from breech position to head position by correcting the fetal position using the chest and knee position method under the guidance of the doctor. However, if the fetus is large and the amniotic fluid is small, it is less likely to change from breech to head position because the space in the uterine cavity is small and the position of the fetus is relatively fixed, so it is more difficult to change from breech to head position. Especially when the ultrasound examination reveals that the fetus has the umbilical cord around the neck, it is not recommended to correct the fetal position by chest and knee position. The breech position is a rare fetal position that increases the risk of obstructed vaginal delivery and therefore requires strict control of the indications for vaginal delivery in the breech position. If the conditions for vaginal delivery are not adequate, a cesarean delivery is recommended.
