When is the best time for caesarean section? The gap between 37 weeks and 40 weeks is bigger than expected.

The Journal of the American Medical Association once published a paper on the changes of caesarean section in China-

From 2008 to 20 18, by analyzing the delivery data of nearly160,000 people, it was found that the cesarean section rate increased from 28.8% in 2008 to 36.7% in 20 18, which indicated that more pregnant women tended to have caesarean section.

Smooth or cut? From the beginning of pregnancy, it has been bothering expectant mothers, and they keep swinging between the two, but even if they are determined to give birth naturally, there are irresistible factors that lead to cesarean section. This is not a pregnant mother exchange group, and pregnant mothers who have caesarean section also have their own considerations.

The full-term fetus has been slow to move, so it has to be "helpless"-

This time, Yu Jing was a little panicked. Until 4 1 week, the doctor found that the amniotic fluid was 3 degrees turbid and did not have the conditions for natural delivery. Finally, she chose caesarean section.

Before the due date, but the amniotic fluid was insufficient, I had to "emergency cut"—

Streams have always been entangled in smoothness or anatomy. I changed my mind several times a day. Until 37 weeks of prenatal examination, I found that there was not much amniotic fluid, so I had to have an urgent operation. Before the abortion resumed, I was put on the bed and pushed into the operating room.

I want a beautiful baby, but I can't wait, so I have to "cut it in advance"—

Ah Chun decided to choose cesarean section from the third trimester, found various immortals to calculate several auspicious days, compared the shift schedule of the director of obstetrics and gynecology, and combined with the doctor's advice, decided to have cesarean section on the day of 39 weeks +2, and everything was ready to wait for the hour.

However, people are not as good as heaven. 38 weeks +3, contractions started at 7 pm and water broke at 9 pm. Open your fingers at dawn and cut them quickly.

In order to keep the baby from falling behind in school, he had to "cut in time"-

Jun Jun baby's due date is September 13, but now the primary school time is stuck. Babies born before August 3 1 every year are delayed to go to school for one year. That year, Jun Jun chose August 30th for her children's school.

There is a folk saying, although it is not absolute, but there are certain ways. Pregnant mothers choose caesarean section at 37 weeks and 40 weeks, and the impact on fetal treasure is definitely different.

Fetuses born at 40 weeks are healthier.

For the fetus, the development is more mature at the 39th week, and the risk of various diseases is lower than that of the babies born by cesarean section at the 37th and 38th weeks.

Second, the fetus born at 40 weeks is smarter.

According to one data, the number of brain neurons in 4 1 week infants is 50% more than that in 37-week infants, and their understanding and cognitive abilities may be better.

But once you decide to choose caesarean section, pregnant mothers must pay attention to these two points:

1) expectant mothers avoid committing a second crime.

After 37 weeks, it is possible to give birth at any time. Some treasure mothers want their babies to stay in their stomachs for a few days as much as possible and choose to postpone cesarean section. However, it is very likely that the baby will not be born early, and even when I went to the hospital, I gave several suggestions for a natural birth. Most unfortunately, they will have a successful caesarean section and suffer a second crime.

2) The medical team is better prepared.

If the operation time is arranged in advance, there will be a fixed operation plan, doctors and nurses will be better prepared, and the state of the mother and fetus will be more stable, which is conducive to the smooth operation. This is a higher safety factor than temporary surgery.

Apart from these special circumstances, when is the right time for a normal pregnancy?

Generally speaking, it is better to choose caesarean section in 39 weeks. Many obstetricians regard 37 weeks to 42 weeks as full-term, but the American Association of Obstetricians and Gynecologists prefers that newborns between 39 weeks and 4 1 week are truly full-term.

Placenta previa: There are two situations: one is complete placenta previa, and caesarean section needs to be prepared in 37 weeks. The other is that marginal placenta previa can last until 38 weeks before operation.

Macrosomia: After 37 weeks of pregnancy, the timing of cesarean section is determined according to the actual situation of placental function and diabetes control.

Twins: Twins with double cashmere and double sheep, because they have two amniotic sacs and two placentas, each with its own room, can try to choose caesarean section until 38 weeks; * * * Twins with placenta should be closely monitored in the third trimester of pregnancy, and caesarean section is usually performed at 35-37 weeks.

Scare the uterus: choose caesarean section for the first delivery, and pay attention to it for the second delivery. If the previous time was a transverse incision in the lower part of the uterus, caesarean section can be performed again at 39 weeks. If it is the first longitudinal incision, caesarean section is usually performed at 36-37 weeks.
