When pregnant, expectant mothers are more concerned about their abdominal circumference. When the abdominal circumference is large, they worry that the fetus will be a huge baby and there will be difficulties during delivery. When the abdominal circumference is small, they worry that the fetal development is not good enough or there is malnutrition, always worrying about the problem of abdominal circumference. Will a fetal abdominal circumference of 370 cause shoulder difficulties during delivery?
1. During pregnancy, expectant mothers should control their abdominal circumference within a normal range. If the abdominal circumference is too large, they need to be alert as there may be other hidden signals. Expectant mothers can measure their abdominal circumference, either lying flat or standing, using a soft tape measure around their belly button.
2. Normally, the abdominal circumference will increase by 0.85 centimeters per week. The growth is unstable before the 20th week and the fastest between the 20th and 24th weeks. The standard abdominal circumference for expectant mothers is only a reference value, and other factors should also be considered. A waist circumference of 370 is 37 centimeters, and this data cannot be used to determine whether there is difficult delivery. It also needs to be combined with other conditions of the expectant mother, so there is generally no major problem.
If the fetus in the abdomen weighs over eight pounds, it will cause difficult delivery, and the probability of difficult delivery is high. Choosing to have a natural delivery for a fetus weighing over eight pounds requires the family to bear great risks. In a natural delivery, if the fetus's head cannot come out, the huge pressure may cause the baby's collarbone to fracture. It is recommended that expectant mothers follow the doctor's arrangements during delivery to reduce risks.
