Fetal malposition includes breech position, transverse position, oblique position and so on. Too much or too little amniotic fluid, huge fetus, multiple fetuses, abnormal maternal pelvis, loose belly of pregnant women, abnormal uterus, etc. may all lead to fetal malposition. The fetal occipital anterior position is the best fetal position for delivery. When there is too much amniotic fluid or the abdominal wall is relaxed, the fetus has more room for movement, while the range of movement is more fixed in cases such as low amniotic fluid or longitudinal uterus, which may cause fetal malposition. If the fetal position is not correct during delivery, it may increase the risk of normal delivery, resulting in difficulty in emerging, intrauterine distress or even fracture, and fetal death in the uterus. Generally, the fetal movement is more frequent around 28 weeks of gestation, and the fetal position is variable, and it is possible that the fetal position will return to head position after a week of review. However, if the fetal position is still abnormal after 36 weeks of gestation, you can perform knee-chest position, moxibustion or external inversion to help restore the normal fetal position, but there is still a certain probability that the abnormal fetal position will return again. Regular maternity checkups, even if there is an abnormal fetal position, can also be appropriate human intervention, but must be carried out under the guidance of a professional doctor.
