Spontaneous delivery is influenced by several factors, among which the size of the pelvis plays a decisive role. It directly affects whether the baby can choose to be born vaginally, and both doctors and mothers attach great importance to pelvic measurement. So, can a pelvic 7.5 be delivered naturally? Follow the editor to find the answer for pregnant women in need.
It is generally believed that if the pelvic outlet exceeds 7.5, vaginal delivery is possible. However, the condition of the pelvis cannot be regarded as the sole criterion for determining whether delivery can proceed smoothly. Because in fact, various factors such as the position, size, and muscle strength of the fetal head are simultaneously affecting it. The size of the pelvis is measured by measuring the distance between each bone.
This is closely related to the physical development and nutritional status of the mother, as well as genetic factors. Many times, even if the pelvic diameter lines are within the normal range, there may still be some differences in their length. In fact, the size and shape of the pelvis are important influencing factors.
If the pelvic shape of the mother is normal, but each diameter line is less than the lowest value within the normal range, once it exceeds 2 centimeters, difficult labor will occur. However, if there are only slight abnormalities in pelvic shape and the diameter is greater than the minimum normal value, smooth delivery can still be carried out. In order to ensure that the size and shape of the pelvis are within the normal range, measurements of the pelvis are taken during prenatal examinations.
