In fact, every mother's physical condition is different. How long it takes to regenerate after caesarean section depends on the recovery of uterus after caesarean section. If the uterus recovers well after caesarean section or the woman's own recovery ability is strong, there is no need to wait for two years after caesarean section.
Is it better to have a natural delivery or a caesarean section?
First, the first child is delivered by caesarean section, and the uterine recovery must be checked before the second child is pregnant.
In order to avoid the risk of uterine rupture and bleeding during delivery caused by unsatisfactory uterine recovery, it is decided to go to a regular hospital to check the recovery of the uterus after giving birth to a second child. Everyone's uterine resilience is different. Whether and when you can have a second child depends on your doctor's advice.
At present, most uterine incisions in cesarean section are transverse incisions in the lower part of uterus. For otherwise healthy women, such incisions usually heal well. Several studies have shown that cesarean scar on uterus will last as long as possible after complete healing. The longer the recovery time after caesarean section, the less likely there will be problems. A foreign study of 170 women shows that if the interval between two pregnancies is less than 6 months, the risk of scar rupture will greatly increase. Another study is more convincing. It surveyed 2409 women who chose vaginal delivery after caesarean section. The results showed that women who were pregnant within 18 months after the last caesarean section were three times more likely to have scar rupture than women who had a longer interval between two pregnancies. The third study shows that women with a history of premature delivery by caesarean section have an increased risk of scar dehiscence, especially if they have no signs of delivery before caesarean section and the interval between deliveries is less than 2 years. Although the above findings may sound scary, the risk of pregnancy scar rupture after caesarean section is very low.
If the interval between two pregnancies is short, there may be more placental problems. A large-scale survey of 187577 women in the United States shows that re-pregnancy within 1 year after caesarean section will increase the risk of placenta previa and placental abruption (referring to the placental abruption from the uterine wall in advance). But of course, the possibility of this risk is very small on the whole.
Second, the first child was delivered by caesarean section. Do you have to choose caesarean section to have a second child?
Many mothers who give birth by caesarean section want to give birth naturally when they have a second child. Theoretically, this is possible. However, it should be noted that if you choose caesarean section for the first delivery, if you want to have another child, it is recommended that there will be certain risks after two to three years, such as uterine rupture. Whether or not to give birth naturally depends first on the condition of the fetus at the time of delivery, and secondly on the contraction of the uterus. If the scar formed after the previous caesarean section affects the contractile function of the uterus and is not conducive to the delivery of the fetus, a second caesarean section is needed; If the fetal condition and uterine contractility are good, you can choose to give birth naturally.
When you are pregnant again after caesarean section, if the following situations occur, it is very likely that natural delivery will be unsuccessful during delivery, which needs careful consideration.
1, the interval between pregnancy again after caesarean section is insufficient.
It is very dangerous for mother to get pregnant again within three years after caesarean section, because the probability of uterine rupture during pregnancy is very high. This is because it takes a long time for the wounds of uterus and abdominal wall to heal completely after cesarean section. Only after the wound is completely healed and has the same function as normal tissue can the fetus be conceived again, so as to ensure that the uterus does not rupture during pregnancy. This time will take about three years.
2. Serious obstetric complications occurred in the second pregnancy.
The second pregnancy has serious obstetric complications, such as severe preeclampsia, placenta previa and placental abruption, which is not suitable for vaginal delivery.
When she is pregnant again, the fetus will have problems.
When pregnant again, the baby has problems, such as intrauterine hypoxia, multiple pregnancy, intrauterine infection, fetal oversize and so on.
Third, what safety precautions should I pay attention to when I am pregnant again after caesarean section?
If you are pregnant again after caesarean section, there is a risk of uterine rupture near delivery. In order to prevent uterine rupture or fetal death, the second-born mother should be hospitalized two weeks in advance for labor, so as to find the problem and deal with it in time.
1 to prevent the abdomen from being squeezed in the third trimester.
In order to prevent the scar from cracking, we must pay attention to protection and not be squeezed. In the third trimester, in daily life, people should avoid being crowded by car and walking, do proper housework, sleep on their back or side, have moderate sex life and avoid being hit in the abdomen.
2. If you have abdominal pain, you should seek medical advice as soon as possible.
Some scarred uterus will spontaneously rupture in the third trimester of pregnancy, and abdominal pain is the main manifestation. Due to the poor healing of uterine scar, with the increase of pregnancy month, the intrauterine pressure increases. Although there is no inducement, the uterus can also swell and rupture from its scar. Different degrees of abdominal pain can occur when the uterus ruptures. Sometimes abdominal pain is mild, but the uterus is broken, so we must be vigilant.
3. Pay attention to fetal movement.
Fetal movement is the irregular movement of the fetus in the uterus, and the speed of fetal movement is one of the early manifestations of fetal safety in the uterus. Generally, there should be 3-5 fetal movements every hour during pregnancy or at least 10 fetal movements a day (12 hours). After caesarean section, if the scar uterus is slightly ruptured and the placenta is abnormal, it will lead to fetal death. At this time, the fetal heart sound disappears. 24-48 hours before fetal death, fetal movement slows down or disappears first. Therefore, paying attention to the changes of fetal movement can find the abnormal situation of the fetus in advance so as to take timely measures.
4, should be hospitalized in advance.
The closer a scarred uterus is to delivery, the greater the risk of rupture. In order to prevent uterine rupture or fetal death, we should be hospitalized two weeks in advance for labor, so as to find problems and deal with them in time.
5. Cesarean section is the best way to give birth again.
For pregnant women after the first caesarean section, 80% have caesarean section during the second delivery, which is safer than vaginal delivery. The timing of caesarean section again should be appropriate. Premature delivery, the fetus is not easy to survive; Too late can easily lead to uterine rupture or stillbirth. Surgery can be performed as long as the fetus is mature, and it is not necessary to wait until labor.
