One thing that worries pregnant mothers who are expecting a baby is a fetal malposition. If the fetal position is not correct, it will greatly increase the difficulty of normal delivery, and if necessary, increase the chance of cesarean delivery. In particularly serious cases, it can also threaten the life of the mother and child. What is fetal malposition? The fetal position is the position of the fetus in the mother’s uterus, and it is a common factor in difficult deliveries. Usually, the occipital anterior position is called normal fetal position in medical science, at this time, the occipital part of the fetal head is the lowest, the fetus is easy to pass through the smallest diameter, this fetal position is generally smoother delivery. The causes of fetal malposition are mainly related to: the shape of the pelvis, the size of the fetus, the amount of amniotic fluid, the relaxation of the abdominal muscles in menstruating mothers, the short umbilical cord, the presence of uterine fibroids or congenital abnormalities of uterine development, etc. Abnormal fetal position may lead to serious complications such as lack of uterine lock, prolonged labor, or even uterine rupture, neonatal birth injury, neonatal asphyxia or even stillbirth, so it is important to pay enough attention to it. Generally speaking, for fetal malposition before 30 weeks of pregnancy, because the fetus is small, the amniotic fluid is large, and the fetus has a large range of motion, it only needs to be observed. However, after 32 weeks of gestation, the fetal position is basically fixed, so it is recommended to correct it between 30 and 34 weeks of gestation. The most common method to correct fetal malposition is to perform chest and knee position correction. If there is still no turning during this period, external inversion of fetal position can be considered for the mother-to-be, but external inversion must have moderate amniotic fluid volume, moderate fetal and maternal weight, and the fetus is not in the pelvis, and there are risks such as cord entanglement or premature placenta during the operation of external inversion. If the fetal position is not adjusted before delivery, most of the pregnancies need to be terminated by cesarean section to avoid damage to mother and baby.
