“Fetal head is too big to give birth naturally”? How big is antepartum biparietal diameter, can pregnant mother give birth naturally smoothly?

“Biparietal diameter”, also known as “fetal head biparietal diameter”, is the length of the widest part between the left and right sides of the fetal head. Doctors will detect the “biparietal diameter” of the fetus to determine whether the fetal development is normal. < / P > < p > in different gestational weeks, the “biparietal diameter” data of fetus is different, which will increase with the increase of gestational weeks, and the growth rate is slightly different in different gestational weeks. < / P > < p > in general, after 6 months of pregnancy, the growth of the fetal “biparietal diameter” will be consistent with the gestational age, that is to say, after 6 months of pregnancy, the fetal “biparietal diameter” is 6cm, after 7 months of pregnancy, the fetal “biparietal diameter” is 7cm, and so on. < / P > < p > “biparietal diameter” small baby, if the situation is only mild, then the development of the fetus will not have any effect, pregnant mother can maintain normal nutrition balance. < / P > < p > but if the “biparietal diameter” is too small and serious, it is likely that the fetal development is seriously malnourished, and even some intellectual problems will occur. The biggest reason is that the pregnant mother’s nutrition intake during pregnancy is insufficient and unbalanced. < / P > < p > and the baby with larger “biparietal diameter” is often due to the excessive nutrition of the pregnant mother during pregnancy, which leads to the rapid weight gain of the fetus. Naturally, the “biparietal diameter” will be larger than the normal fetus. < / P > < p > excessive fetal weight will not only increase the burden of pregnant women, but also increase the difficulty of delivery. Therefore, it is equally important for pregnant women to control their weight while supplementing nutrition. < / P > < p > before labor, the doctor will evaluate whether the pregnant mother can give birth independently by measuring the “biparietal diameter” of the fetus. Of course, this method is only one of the factors to judge. < / P > < p > the three factors of spontaneous delivery are fetal development, birth canal and productivity, among which “biparietal diameter” is the fetal development. Generally speaking, if the circumference of the “biparietal diameter” of the fetus is commensurate with the pelvis of the mother, then the pregnant mother can give birth autonomously. < / P > < p > usually the “biparietal diameter” of the fetus should be & lt; 9.8cm to pass through the birth canal smoothly. If the “biparietal diameter” reaches 9.8cm, then it is not suitable for spontaneous delivery. < / P > < p > pregnant women need extra calcium only in the case of calcium deficiency during pregnancy. If they blindly supplement calcium by themselves, it is easy to cause calcium excess and lead to fetal head too large. < / P > < p > in the pregnancy test, if the doctor reminds the pregnant mother that the fetal head is too large, then the pregnant mother should pay attention to control her diet, control her weight and avoid the baby’s overgrowth. < / P > < p > under normal circumstances, as long as the fetal head is not too large, the parturient can give birth autonomously. However, if the “biparietal diameter” is too large, the doctor may take “side cutting” during delivery, and the pregnant mother should have a psychological preparation. < / P > < p > during pregnancy, the “biparietal diameter” of the fetus is only one of the factors to evaluate whether it can give birth autonomously, not a decision. Therefore, pregnant mothers should not over entangle this data. To ensure the nutrition and balance of diet is the most beneficial. Pregnant dream “Golden Dragon” is about to “give birth to a boy”?
