The earliest weeks a baby can survive, and the earliest weeks a fetus can survive

In general, a child is likely to survive after 28 weeks of intrauterine birth. Births before 28 weeks are considered miscarriages and are generally unlikely to survive. Even after 28 weeks, perinatal mortality is significantly higher than for full-term children.

During pregnancy, it is necessary to pay attention to strengthening prenatal examination, strengthen personal protection, and avoid accidents, preferably after 37 weeks.

It is generally believed that the fetus at 24 weeks is the key to survival in terms of the degree of development, and premature babies born before 22 weeks are generally not viable. With medical support, the probability of surviving preterm birth at 23 weeks is about 17%, the probability of surviving preterm birth at 24 weeks is about 39%, and the probability of surviving preterm birth at 25 weeks is about 50%. A premature baby after 34 weeks is almost indistinguishable from a full-term baby.

Everyone knows that medicine is becoming more and more advanced, and even if the baby is not delivered to term, it is possible to survive. And now the premature baby is still relatively long, so when facing a premature baby, the mother does not need to worry too much, to trust the current doctors and medical technology, and actively create a good living environment for the baby. Of course, if the morning time is too early, it may affect the baby's life, so today I will introduce to you the earliest weeks of fetal birth can survive.

1. Generally speaking, 24 weeks of pregnancy and 28 weeks of pregnancy are two key time points, the fetal heart fluctuates regularly at 18 to 20 weeks of pregnancy, and the fetal heartbeat can be detected with a stethoscope at 22 weeks of pregnancy. The development of the fetus's lungs is relatively slow, and it is not until 23 or 24 weeks that the fetus's lungs develop and the surface expansion of the alveoli in the lungs is initially formed. Therefore, the probability of survival of a premature baby born before 22 weeks of pregnancy is very low, and in most hospitals, premature babies born before 24 weeks are treated as miscarriages.

2. The specific survival probability. If the preterm baby is 23 weeks pregnant, the probability of survival is about 39%, the probability of survival of a preterm baby at 25 weeks is 50%, the survival rate of a preterm baby at 28 weeks of pregnancy is 80%, the survival rate of a preterm baby at 27 weeks is 90%, the probability of survival of a preterm baby at 28 to 31 weeks is 90%, and the probability of survival at 32 to 33 weeks is 95%. Preterm babies after 34 weeks are basically the same as babies born at term.

That's all there is to know about how a fetus can survive in the first few weeks of life. Of course, there are some exceptions in this world, for example, according to relevant records, the world's first premature baby born and surviving came from Canada, and this premature baby was born at 21 weeks and five days, and finally survived. In fact, there is a certain probability that premature babies will survive or not.

Now that medical technology is developed, the survival rate of premature birth of the fetus is much higher, and when my cousin gave birth, I saw the first five and a half months of surviving baby in Beijing Maternal and Child Health Hospital! The cost is very large, you have to stay in the incubator until full-term, and you have to get an injection to promote growth and development every once in a while, and one injection was 8,000 back then, and now I don't know how much it is.

The fetus is born as early as about 22 weeks of gestation and may survive with medical rescue and special care.

Fetuses born around 22 weeks of pregnancy are not fully mature, their lungs are not fully mature, they cannot breathe air, and they need to be kept alive by ventilators and other equipment. In addition, since its immune system is not yet fully established, it is susceptible to various diseases. As a result, these premature babies require medical care in special neonatal intensive care units, including respiratory support, nutritional support, infection prevention and control, and more.

Under the care of medical personnel, some babies can survive, but the survival rate is relatively low, and there may be some sequelae, such as vision, hearing, intelligence and other problems.

Indicators of fetal survival:

1. First trimester:

If there is no abdominal pain or bleeding before 7 weeks of pregnancy, and there is early pregnancy reaction, you can refer to the value of HCG and progesterone to estimate whether the fetus is alive.

2. Second and third trimesters:

Before 16 weeks of pregnancy, the fetal heart rate is monitored by B ultrasound to determine whether the fetus is alive and developing, generally 16-20 weeks of pregnancy, pregnant women can consciously have a wheel of fetal movement, and can judge whether the fetus is alive according to the fetal heart rate and fetal movement. A normal fetal heart rate is usually between 110 and 160 beats per minute. The average fetal movement is 3-5 times per hour, and more than 30 times in 12 hours, which is considered normal fetal movement.

If the fetal heart rate and fetal movement are within the normal range, it basically indicates that the fetus is alive. <>
