The fastest way to turn from breech to head position is as follows: 1. External inversion: external inversion is a surgical operation that needs to be done by an obstetrician. The general operation can be done between 32-40 weeks of gestation, and if it goes smoothly, it takes about 2-3 minutes to change from breech position to head position. External breech reversal is a surgical operation with certain surgical risks, and the success rate of the operation is about 70%-80%. There is a risk of fetal hypoxia due to slowing of the fetal heartbeat during the transfer, and there is also a risk of placental abruption. If it happens, it may need to be turned into emergency cesarean section, which is the method of external inversion; 2. Knee-chest position: Knee-chest position is usually at 30 weeks, if the ultrasound indicates that the fetus is still breech, you can try to do knee-chest position. Knee-chest position needs to take the position of the chest and elbow, and knees on the bed, the buttocks is also the pelvis is higher than the body parts. This allows the fetal head to be turned to the pelvic position by using the effect of head weight and gravity, that is, to the head position. The knee-chest position is usually done three times a day for about 10-15 minutes each time. 3. Traditional medicine: moxibustion is used to stimulate the Zhiyin point, which can increase fetal movement after moxibustion, and it is possible to turn into the head position after the fetal movement increases.
