Why does the doctor recommend caesarean section for 39 weeks instead of 40 weeks before the expected date of delivery?

Although today's pregnant mothers are not inclined to choose caesarean section, they still have to face caesarean section when they have no choice. For example, the fetal position is not correct, the child is too big, the pelvic structure is abnormal, the productivity is insufficient, and the mentality is unstable.

Pregnant mothers were a little confused when asked to have a caesarean section. How many weeks is caesarean section better? Do I have to wait 40 weeks before the due date? If you consult a doctor, most doctors recommend that you be pregnant for 39 weeks instead of waiting for the expected date of delivery for 40 weeks. Why is this? Among them, it is still very particular.

The fetus is fully developed at 39 weeks, so the doctor's suggestion of giving birth at 39 weeks has certain practical basis.

If we know the law of fetal development, it will be more clear. The fetus will develop more completely at 39 weeks, and it will be less difficult to care after birth, so that the baby can grow healthily and sturdily.

1, 39 weeks pregnant, the fetal weight will be more ideal:

It is said that one day in the mother's belly is equivalent to staying outside for 10 days, and the weight will increase at the rate of 15g every day.

The average fetal weight at 37 weeks is 3000 grams.

The average fetal weight at 38 weeks is 3200 grams.

The average fetal weight at 39 weeks and 40 weeks is 3200-3400 grams.

After 39 weeks, the growth rate of fetal weight slows down, so the fetus will not be wronged when born at 39 weeks.

2. At the 39th week of pregnancy, the development of fetal organs is more perfect.

By the 38th week of pregnancy, all the organs of the fetus have been fully developed, and the lungs and brain are fully functional, but they will continue to develop until they mature.

It can be seen that there is still a little gap between the organs and maturity of the fetus at 38 weeks, and Zhou Huigeng is mature at 39 weeks. This is more powerful for the health of the fetus.

3. At the 39th week of pregnancy, the fetus is more adaptable to the external environment.

By the 39th week of pregnancy, the fetal fat layer will be thicker, the color of fetal skin will change from pink to white or blue-red, the outer skin will fall off, new skin will grow again, fetal hair will disappear, and fetal skin will look smoother and better.

From the appearance, the 39-week-old baby will be more beautiful after birth, and mothers will not be disgusted.

In terms of adaptability, the fetus enters the environment of about 20 degrees from the environment of about 40 degrees, and the temperature difference is very large. Only skin fat is thick enough to keep him warm.

4. The immune function of the fetus is stronger at the 39th week of pregnancy.

At 38 weeks of pregnancy, the fetal immune system has been established, but it is not very mature. By the 39th week of pregnancy, the immune system of the fetus is more perfect, and more antibodies are absorbed from the mother, which can help the fetus resist more diseases. Therefore, children born at 39 weeks are more immune and less likely to get sick. This is also a decompression thing for my mother.

It is not recommended to choose 40 weeks to reduce the chance of committing a second crime. The later the gestational age, the greater the chance of fetal activation. Many pregnant mothers want to wait until 40 weeks before cesarean section, which is also not recommended. When the fetus starts, there will be physiological phenomena such as uterine contraction pain, redness and swelling, and water breakthrough.

When contractions occur, pregnant mothers will feel unbearable abdominal pain and fidget. I want to sleep, I can't sleep, I feel uncomfortable when I wake up, and that kind of taste can't be solved.

When there is redness, there may be no special symptoms, but it will worry pregnant mothers. Is there something wrong with the fetus or with your own health?

Abdominal pain will not occur when water is broken, but the fetus will face risks such as umbilical cord prolapse and hypoxia. The situation is urgent and needs to be sent to the hospital immediately, which will also make pregnant mothers very nervous.

Many pregnant mothers choose caesarean section just to avoid the pain of uterine contraction. If caesarean section is performed for 40 weeks, the chances of fetal initiation will increase, and the chances of pregnant mothers suffering from twice will also increase.

40 weeks is not recommended to reduce the risk of cesarean section. If the fetus starts or breaks water, it needs to be rushed to the hospital. After entering the hospital, doctors must respond immediately, deploy doctors, do blood tests for pregnant women, prepare surgical supplies, and make surgical plans. These preparations are very busy and tense.

In case there are no beds in the hospital, the hospital will have no resources to allocate to the pregnant women, and the lives of the pregnant women and the fetus will be in danger. In case the pregnant mother has high blood pressure or other diseases, the hospital may not have time to make careful plans, and it will be difficult to save the lives of the mother and the fetus.

A while ago, a pregnant woman encountered such a situation, no bed, old, eclampsia. As a result, there was a mistake in the middle link, which led to the death of pregnant women. This is a very regrettable thing.

In short, if it meets the indications of caesarean section, it can be prepared according to 39 weeks, not too early or delayed to 40 weeks. It is good for both the mother and the fetus to make an appointment with the doctor in advance and get ready.

Obviously, 40 weeks is the most mature state of the fetus. The doctor also said that 40 weeks ago, it was better for the fetus to stay in the fetus for one more day than to stay outside for one week. Why do doctors advise pregnant women to have a caesarean section at 39 weeks?

In fact, the doctor considered the risk, and the risk of cutting in advance was completely different from that of the baby. For pregnant women and doctors, the risk of cutting after the fetus begins to develop is greater. Why do you say that?

When the fetus is fully developed, the fontanel on the small head will release a substance, and then the pregnant mother's brain will secrete this substance after receiving the signal. After receiving the instruction, the body will start to start a regular intense contraction, and then start to "open your fingers" for more than ten hours. This is the pain of opening the uterus that must be experienced in natural childbirth, but if natural childbirth cannot be directly performed by caesarean section, there is no need to experience this kind of disaster, but if the fetus is started, the mother will suffer another crime. After going through the pain of 12 and another "skin cutting", plus a longer postpartum recovery period, I think everyone dare not and don't want to try it easily! In view of this, doctors generally do not recommend caesarean section until the expected date of delivery is 40 weeks.

After the fetus is started, some people can open the cervix faster. If you open the cervix, the baby will get stuck in the middle, especially the pelvic stenosis, which is really troublesome. At this time, even experienced doctors will be confused, which is also a huge challenge for the baby and mother, and may even be life-threatening. In addition, some pregnant mothers break their amniotic fluid first, which does not meet the natural delivery index. Now that they have broken amniotic fluid, pregnant women don't know how to deal with it for a while, which will also be bad for the baby and the new mother. To take a step back, most fetuses have to have an emergency caesarean section, which will increase many unnecessary risks, such as insufficient beds and insufficient medical staff. The risks faced by the baby are higher than the planned ordinary caesarean section.

Some people may ask, then why not do it in 37 or 38 weeks? These two weeks are not impossible for caesarean section, but if the maturity of the baby is considered, 39 weeks is the most suitable. Although the 37-week-old fetus is full-term, its physical function is not fully developed. An almost mature apple is different from a fully mature apple, let alone a baby. If the baby is delivered by caesarean section at the 37th week of pregnancy, the risk of respiratory diseases will be higher, it will take a long time to adapt to life outside the uterus, and the immunity may be poor.

For the above reasons, doctors generally recommend that pregnant mothers have caesarean section at 39 weeks of pregnancy instead of 40 weeks of expected delivery. In short, doctors also give advice according to the actual situation. The seemingly ordinary advice actually includes the doctor's consideration for the mother and the baby. Its purpose is to make the mother suffer less and let the baby be born safely.

As we all know, the pregnancy cycle is 40 weeks. By the 40th week, the fetus is like a "ripe watermelon", which can leave its mother and come into this world.

But if the pregnant mother chooses caesarean section, the doctor will recommend the operation at 39 weeks instead of waiting for 40 weeks.

Many pregnant mothers will have such doubts: Is the 39-week-old fetus mature? Can a 39-week-old fetus start caesarean section? Why is a 39-week caesarean section recommended?

Let's look at the first question first: Is the 39-week-old fetus mature?

The answer is yes, in fact, the fetus will be full-term at 37 weeks, which means that the baby is born at this time, and there is basically no danger.

Although the 40-week-old fetus will develop better, for many reasons, doctors will advise pregnant mothers to have caesarean section in advance, and don't wait until the baby starts caesarean section. At this time, the baby cut out will not have the problem of premature birth.

The second question: can the fetus not start caesarean section?

Sure! Because the baby is mature, the doctor can take it out by surgery without waiting for the baby to start on its own.

The third question: Why do you recommend a 39-week caesarean section?

39 weeks caesarean section has the following advantages:

1, pregnant women suffer less.

The baby will cause contractions at first. This process is very painful. It was okay at first, but the more I got to the back, the more I could not stand it. If the baby starts caesarean section, the mother will be very painful, but if you have caesarean section at 39 weeks, the baby will be removed by the doctor before it starts, and the mother will suffer less.

2. It is safer to cut in advance.

The speed of finger opening varies from person to person. Some pregnant women need more than ten hours to open their fingers, and some will open their fingers in two or three hours. If the baby suddenly starts and the pregnant woman opens her fingers quickly, it is easy to be dangerous, because the baby may not be suitable for natural delivery. If caesarean section is performed at this time, there will be great risks. It's better to have a caesarean section in advance, which is safer.

Why does the doctor recommend caesarean section for 39 weeks instead of 40 weeks before the expected date of delivery? The pregnant woman's fetal position is not correct, and the fetus is horizontal. Originally, she wanted to give birth naturally, but this fetal position could not give birth naturally, so she reluctantly accepted the doctor's advice-caesarean section. Because she thinks that the bigger the gestational age, the more mature the fetus will be, so she insists on pregnancy until the 40th week of pregnancy. However, one night, she had a terrible stomachache. She went to the hospital for examination and found that the fetus started on its own, but it did not meet the conditions for natural delivery, so she could only have a temporary caesarean section.

What is the difference between 39 weeks and 40 weeks of pregnancy for pregnant women and fetuses? Judging from the maturity of fetal development, the development of organs, especially lungs, will be more mature, the brain will develop further, and the weight gain of the fetus will be less, which is about 100-300 grams a week. The fetus will develop faster in the uterus than outside the uterus, so the fetus at 40 weeks' gestation will be more perfect than the fetus at 39 weeks' gestation.

If the pregnant woman's uterus is in danger of rupture, it is safer to have a caesarean section at 39 weeks of pregnancy than at 40 weeks of pregnancy.

However, for pregnant women, caesarean section at 40 weeks of pregnancy means greater risks. Pregnant women will have uterine contraction pain in advance, and the fetus may enter the birth canal of pregnant women, resulting in delayed delivery and dystocia, which may easily lead to acute hypoxia of the fetus. It will be more difficult for doctors to perform caesarean section in order to save the life of the fetus. The second delivery is more risky for the fetus and pregnant women, and it is a kind of torture for both pregnant women and the fetus.

If pregnant women choose caesarean section, then caesarean section is performed at 39-40 weeks of pregnancy, and the fetus is mature. There won't be much difference. Pregnant women don't need to risk pregnancy for fetal development until 40 weeks. If the doctor recommends 39 weeks, then the pregnant woman will cooperate with the doctor.

Many pregnant mothers will always struggle to choose caesarean section or natural delivery in the later stage, and when caesarean section is better. In fact, whether it is a 39-week caesarean section or a 40-week caesarean section, these two time periods are the best time for caesarean section and will not have much impact on the fetus.

Ma Bao knew that the fetus would be full-term after 37 weeks of pregnancy. Under normal circumstances, full-term fetuses can be born smoothly. After 37 weeks, the fetal organs have matured and the body has certain immunity. They have the ability to adapt to the external environment, so it is ok if the fetus gives birth at 37 weeks.

However, compared with 39-week or full-term newborns, the risk of respiratory diseases in 38-week caesarean section newborns will double, and that in 37-week caesarean section newborns will quadruple. So generally speaking, the hospital will advise pregnant women to have a caesarean section after 39 weeks.

Why does the doctor recommend caesarean section in 39 weeks instead of 40 weeks?

There are factors that are not conducive to the continued growth of the fetus, such as a history of caesarean section, abnormal fetal position, hypertension, placental calcification or amniotic fluid turbidity. Doctors will advise pregnant women to have a caesarean section.

The best time to choose caesarean section is the 39th week of pregnancy, because at this time, all the development of the fetus is mature, and there is less chance of emergency laparotomy when there is labor pains and water breakthrough, and pregnant women do not need to experience the double torture of contractions, labor pains and surgical pains, which is more conducive to maternal physical recovery. Caesarean section one week in advance, the hospital is more prepared, and the operation time and bed arrangement are easier to make an appointment.

Generally, 40-week caesarean section is mostly acute caesarean section, mostly due to vaginal bleeding and premature rupture of amniotic fluid, resulting in oligohydramnios and fetal distress, so caesarean section must be performed immediately, otherwise it will endanger the lives of pregnant women and fetuses.

Therefore, the doctor will recommend a caesarean section in 39 weeks instead of 40 weeks. It is best for pregnant mothers to follow the doctor's arrangement to ensure the safe birth of the fetus.

Hello, I'm happy dad's diary, and I'm glad to answer your question.

With the progress of society and the continuous improvement of medical technology, more and more mothers choose caesarean section when giving birth to their children for various reasons.

But when to have a caesarean section, many mothers are confused:

Isn't it that the baby will be full-term in 37 weeks, and the later the baby grows and develops, the better the resistance after birth? So why do doctors ask for caesarean section in 40 weeks or later, but ask for caesarean section in 39 weeks or so?

So should caesarean section be postponed or should it be done at 39 weeks?

In fact, it is very scientific for doctors to recommend 39-week caesarean section.

Caesarean section 39 weeks ago, the risk of respiratory infection complications of newborn babies is relatively high, and the probability of weak immunity after birth is also relatively high.

After 40 weeks, it's not so good. From the 40th week, with the increase of mother's placental maturity, the amniotic fluid volume in the body will be significantly reduced, and it will be reduced by 30% by the 42nd week. The remaining amniotic fluid is not enough to maintain the normal growth and development of the baby. What's more, with the decrease of amniotic fluid volume, the probability of amniotic fluid being polluted has also greatly increased, which is about three times higher than that at 39 weeks. This has a very serious impact on the baby.

In addition, 40 weeks is the expected date of delivery in the standard sense, and quite a few mothers have already shown signs of labor.

For example, if you wait until this time to have a caesarean section, mothers will undoubtedly suffer two sins, that is, they have experienced both the pain of contractions and the pain of caesarean section. Moreover, uterine contraction has a great influence on the doctor's operation, and unnecessary trouble will occur if you are not careful.

Therefore, most doctors will advise mothers to choose caesarean section at 39 weeks.

Generally speaking, it is recommended to have a caesarean section in 39 weeks, which is the comprehensive consideration of doctors.

Of course, if mother really wants to postpone caesarean section, she can also tell the doctor what she thinks, and if the situation permits after the examination, it is not bad.

We know that the expected delivery date is 40 weeks, and the delivery usually takes 40 weeks. Why do some people choose to give birth around 39 weeks instead of 40 weeks ago if it is a caesarean section?

Many pregnant mothers have consulted this question "Which week is the best for caesarean section", and the answer is generally about 39 weeks. This is not groundless, but has scientific basis.

Why not choose to be pregnant for 40 weeks? We all know that the expected date of delivery is 40 weeks, but the fetus may not be born after 40 weeks. The fetus is full-term at 37 weeks and may be born at any time.

A partner suddenly broke water in 37 weeks and rushed to the hospital. The doctor said that too much amniotic fluid could not protect the fetus, so the baby was born at 37 weeks.

When I gave birth to Bauer, I wanted to be born 40 weeks before Daihe. I thought there was nothing wrong, and I didn't care. However, on the 38th week and 3rd day, Bauer suddenly became ill and was taken to the hospital. At that time, I opened a finger and had a caesarean section in time.

If caesarean section is always planned for 40 weeks, it may present some passive situations. 1, the situation is underestimated.

If you plan to be born at 40 weeks, you may be very careless, thinking that it is still early and the protection measures are not in place. Once some unexpected problems appear, some people will be at a loss. Just like my other half, because of underestimation, I did some housework at night and got tired accidentally.

2. The ward was not booked in time.

If you want to book a better ward, such as a single room, you need to make an appointment in advance. If the plan is regenerated within 40 weeks, the appointment will be postponed. If you start early, it will be too late to book a bed. So plan ahead and don't be caught off guard.

3. Endure the pain of uterine contraction

According to the pregnancy bible, about 55% pregnant mothers will give birth before the 40 th week of pregnancy, which is quite large. If you go to caesarean section for 40 weeks, contractions will occur in many cases. A large part of the reason for caesarean section is fear of uterine contraction pain. Therefore, this goes against the original intention of choosing caesarean section, which is also unacceptable to many pregnant women.

Why do you have to ask the doctor every time around 39 weeks, when is the caesarean section? Some doctors say 37 weeks is enough, some doctors say to go again, and some doctors say 39 weeks. The most popular saying is 39 weeks. Why 39 weeks? The first reason is because of this study:

An article published in the American Journal of Obstetrics and Gynecology said that "newborns born between 39 weeks and 4 weeks/kloc-0 weeks are truly full-term babies". They found that newborns born before 39 weeks are slightly behind in the development of breathing, listening and future learning ability.

After 39 weeks, the fetal fat layer will still thicken, and the thicker the fat layer, the stronger the temperature regulation after birth. Fetal weight will increase by14g every day. As long as you are in your stomach, you will gain weight and get better care after birth. The fetus will constantly absorb antibodies from the mother's blood and amniotic fluid to enhance immunity and fight against various diseases, so it is not easy to get sick after birth.

Therefore, from the theoretical analysis and the actual investigation results, it is considered that 39 weeks of fetus is the best.

But in any case, if there is an emergency, whether it is 39 weeks or not, you should go to the hospital for caesarean section in time, and don't worry too much about it.

In China, 37 weeks is not considered premature, and 39 weeks to 40 weeks is the maturity of the fetus, which means it is very close to delivery. The doctor suggested a 39-week cesarean section to avoid natural delivery of the fetus. If the fetus has an attack, the time will be tight. If the operation is not performed immediately, Ma Bao will be very painful, and the fetus may be delayed for a long time. Within 39 weeks before onset, Ma Bao can enter the hospital at her own time, and the doctor will arrange it as early as possible. The doctor didn't tell me until the baby came out early by caesarean section. I still dragged my stomach and endured the pain and went through the formalities. It is also very hard for me, so try to have a caesarean section one or two days before 39 weeks, otherwise the baby will come out early and the baby will suffer the pain of natural delivery.

According to the data published in China Maternal and Child Health Development Report (20 19), the national caesarean section rate was 36.7% in 20 18, indicating that the proportion of women who have adopted caesarean section in China is relatively high, and many women who have no indications for caesarean section choose to have caesarean section by themselves. For such women, it is often difficult for them to choose when to have a caesarean section.

In order to solve this problem, I made a statistics in the parenting group, and got 3 1 baby mother's reply, of which 9 were delivered by caesarean section at 38 weeks' gestation, accounting for 29.03%. Caesarean section 19 cases, accounting for 6 1.29%. Two cases (6.45%) delivered by cesarean section at 40 weeks' gestation. Another one was born naturally, but by the time she was 4 1 week pregnant, the baby just didn't come out and the oxytocin didn't move. Finally, she failed to survive the baby and had a caesarean section at 4 1 week of pregnancy.

The above is just my statistics, just a small sample, and it can't represent the whole group. But it also conforms to the objective facts. Caesarean sections are basically at 38-39 weeks of pregnancy, and many caesarean sections are at 39 weeks of pregnancy. Usually doctors also recommend caesarean section at 39 weeks of pregnancy.

Reduce the risk of parturient Although many parturients who have no indications for cesarean section will choose cesarean section, there are still many parturients who have indications for cesarean section who have to choose cesarean section. If these women wait until the 40th week of pregnancy, there may be signs of labor, which will increase the risk of delivery for women with indications of caesarean section. However, if caesarean section is advanced to 39 weeks of pregnancy, the fetus is mature at this time, and there is still 1 week from the expected date of delivery, and the probability of signs of labor is relatively less than 40 weeks of pregnancy, which can further reduce the risk of women with indications of caesarean section to some extent.

In fact, many parturients have indications for caesarean section, which are generally determined according to the actual situation of the parturient. For example, some women may have heart disease, and the time of caesarean section may be advanced to 37 weeks of pregnancy or before.

Avoid making your mother suffer from double crimes. If the expected date of delivery is 40 weeks, the mother may show signs of labor, such as uterine contraction pain, which will make Ma Bao suffer from labor pains; If the amniotic fluid breaks, it will make Ma Bao very nervous at home and increase her fear.

If the caesarean section is advanced to the 39th week of pregnancy, the probability of signs of labor is less, so that Ma Bao can avoid the charge of signs of labor and only have to bear the charge of caesarean section.

In addition, I read an article on the Internet that a smooth incision is good for the baby. For example, the baby can make the respiratory system better by squeezing, and can also help the uterus recover, secrete oxytocin during natural delivery, and help the postpartum milk discharge. I just want to say that since I have to go through such a painful period, I feel that it is good to have a natural delivery. If there is no indication for caesarean section, it is better to choose a natural delivery directly. Of course, there are also many women who have to have a cesarean section because of labor stoppage, which is helpless.

In short, if you choose caesarean section, it is best to arrive at 39 weeks of pregnancy in advance. At this time, the fetus is fully developed, and the probability of signs of labor is lower than 40 weeks of pregnancy, so that you can avoid suffering from two crimes.

If the delivery is normal, the pregnant mother can't choose the birth time of the fetus. She can't give birth to a baby until the melon is ripe and there are symptoms of labor, but caesarean section is different. Expectant mothers can choose when to remove their babies. Therefore, some pregnant mothers who are in a hurry to unload goods will have caesarean section in advance. So what's the difference between a 39-week caesarean section and a 40-week caesarean section? Why does the doctor recommend a 39-week caesarean section?

Caesarean section should not be premature. The fetus is full-term at 3 7 weeks. It is normal to be born at this time, but the 37-week-old baby is not fully mature, with poor cardiopulmonary function and impaired breathing. If it is cut out at this time, the baby's physique and resistance are relatively weak, so caesarean section is generally not recommended at 37 weeks.

Some expectant mothers may wonder: isn't caesarean section better after 40 weeks of pregnancy? Why not recommend a 40-week caesarean section?

Reasons why caesarean section is not recommended for 40 weeks. At 40 weeks, the baby is quite mature, physically more than 37 Zhou Qiang, with high resistance. But caesarean section is different from natural delivery. If you wait until 4 0 weeks for caesarean section, the baby will grow too big, but it will increase the difficulty of the operation, and the pregnant mother's uterus will be strongly oppressed, which is likely to open the cervix in advance and increase the risk of the operation. Therefore, it is not recommended to wait until 40 weeks of pregnancy before caesarean section.

The best time for caesarean section is neither too early nor too late, and the best time is 39 weeks. At 39 weeks, the baby's development is basically mature, the cardiopulmonary function is more mature than at 37 weeks, the baby's brain development is more perfect, and the intelligence is relatively higher. The 39-week-old baby's body shape is also relatively moderate, and the operation will be easier and the risk will be much smaller.

Therefore, pregnant mothers who plan to have a caesarean section should not rush to unload the goods in advance, and do not think that the longer the baby stays in the womb, the better the development. It is best to have a caesarean section in 38-39 weeks, which is good for yourself and the fetus.
