Pregnant women already have some experience when giving birth to their third child, but relying solely on experience during childbirth is far from enough. Scientific diagnosis and sufficient preparation are also needed to give birth to the baby more smoothly. So, how long will it take for the third child to be born when it is half pregnant?
Only when the fetus is fully inserted into the pelvic cavity can it possibly have a vaginal delivery. Therefore, fetal insertion into the pelvic cavity is a necessary condition for vaginal delivery. Generally, if the baby has already partially entered the pelvic cavity, it can quickly be fully inserted under the action of uterine contractions. Therefore, if the examination finds that the fetus has already entered the womb halfway, then it is time to prepare for delivery at any time. At this point, it is usually time to complete the hospitalization procedures.
There is a narrow gap in the pelvis, usually only about 100 millimeters for women, and the toughness of the pelvis is relatively poor. Therefore, if the fetal biparietal diameter is greater than 100 millimeters, it is difficult for the fetus to pass through the pelvis smoothly. Even if half of the fetus has already entered the pelvis, it is also difficult to give birth smoothly.
Under normal circumstances, if a baby has half of their pelvic muscles, they can fully enter the pelvic cavity within 12 hours. However, if the baby enters the pelvic cavity for a longer period of time, it is likely that there are problems with the baby during the process, such as improper fetal position or large biparietal diameter, which may cause difficulty in entering the pelvic cavity. In addition, if the fetus is not fully delivered within 24 hours after half of the delivery, timely methods such as cesarean section and lateral incision should be taken to assist in delivery, otherwise the risks for both the fetus and the mother will be greatly increased.
