Premature delivery from 24 to 37 weeks is called premature delivery, but after 37 weeks, the fetus is relatively mature in all aspects. If the natural delivery of the fetus is normal, it is also premature. So if 37 weeks +4, there is generally no need for additional abortion, because abortion is also a drug, but all drugs have certain side effects.
The development of fetal organs has been basically improved after 37 weeks of pregnancy and 4 days of pregnancy. According to the number of weeks of pregnancy, it is exactly after term. Generally speaking, if the menstrual cycle before pregnancy is relatively normal and comes regularly every month, the development of fetal organs has basically improved after 37 weeks of pregnancy. You can consider not having a baby, waiting for signs of labor and giving birth directly.
If the fetal biparietal diameter is too small and the fetal weight is less than 2.5Kg, it is recommended to protect the fetus. It is better for the fetus to stay in the mother's body for one day than to stay outside for ten days. After all, transplantation may have different degrees of discomfort. For a baby whose fetal weight is less than 2.5Kg, some of his organs may be underdeveloped, such as lung, brain and lung. Even in the first few years after the baby is born, it is easy to catch a cold after a long time.
Babies born after 37 weeks are full-term babies. Under normal circumstances, it is not necessary for a pregnant mother to have a baby during the 37 weeks and 4 days of pregnancy. As long as the baby shows signs of birth, you can choose to have a baby.
For pregnant mothers, in judging whether it is necessary to protect the fetus, besides the necessary conditions, whether the gestational age is more than 37 weeks, such as whether the baby's own growth and development are good, whether the pregnant mother's personal physical condition is suitable for continuing pregnancy, etc., all need to take the baby into account.
Conclusion It is correct that it is not necessary to protect the fetus after full term (after 37 weeks), and whether to protect the fetus before 37 weeks needs to be decided according to the patient's wishes and local health and medical conditions. The greater the gestational age, the lower the probability of fetal lung immaturity, but only the baby who is pregnant for more than 39 weeks, that is, the baby in the late term, will completely rule out the possibility of fetal lung immaturity and try to terminate the pregnancy after 39 weeks. It is generally not a problem to start naturally after 37 weeks.
