The fetal delivery style is divided into longitudinal and transverse delivery styles, and the direction of fetal position in longitudinal delivery style is divided into head-first and breech-first, and the direction of fetal position in transverse delivery style is shoulder-first. There are 6 fetal positions for both cephalic and breech first, which are divided into left anterior, left transverse, left posterior, right anterior, right transverse and right posterior, and 4 fetal positions for shoulder first, which are divided into left anterior, left posterior, right anterior and right posterior. Therefore there are not 6 fetal positions, among which the smoother way of delivery is the occipito-anterior position in the longitudinal delivery style head first exposure, with 95%-97% of mothers in the occipito-anterior position of head first exposure, with a few cases of other positions. In the occipital-anterior position, the fetus’ head is the first to enter the pelvis, the head is lowered in front of the occipital area, and the back of the fetus is facing the mother’s abdomen, and the fetus is facing the mother’s back. In other positions, the mother is more likely to have a difficult delivery and the risk of delivery is significantly higher. In the breech-first position, the head of the fetus is the last to be delivered, which can lead to difficulties in delivery and fetal asphyxia. If the fetus is not handled properly, the mother’s uterus may rupture and hemorrhage. If the fetal position is not suitable, delivery by cesarean section may be required if necessary. It is recommended that pregnant women go to the hospital for pregnancy checkups on time during pregnancy and pay attention to observing the change of fetal position before delivery. Since the fetus can turn on its own in the abdomen, there is no need to worry too much about the fetal malposition in the early stage, usually the fetus will adjust itself through activities. If the fetus cannot be reset on its own after examination at more than 30 weeks, it is necessary to correct the fetal position by means of correction.
