Although it is a pity, it has to be said that it is not necessary.
At 22 weeks of pregnancy, it is extremely difficult to treat the fetus at birth, and the survival rate is extremely low.
1. At 22 weeks of pregnancy, the fetus is immature, and it is extremely difficult to treat.
1) Ultra-premature babies born at 22 weeks of pregnancy have to overcome countless medical difficulties
- Breathe off
At 22 weeks of pregnancy, the lungs are far from mature, and the fetus born at this time cannot breathe on its own, and there will be frequent apnea and even respiratory failure. Respiratory support must be relied upon by a ventilator to have any chance of survival.
- Infection off
For ultra-premature babies, infection is a difficult hurdle and is highly susceptible to various infectious diseases, even sepsis. Their extremely thin skin and umbilical cord can become a channel for germs to invade, and once they cause infection, they are more dangerous than full-term fetuses, because ultra-small gestational-age babies are immature, have worse physical fitness, and have an extremely immature immune system, and extremely low immunity.
- Bleeding off
The coagulation mechanism of ultra-premature babies has not yet developed, the structure of blood vessels is still unstable, and the development of various organs is not yet mature.
Pulmonary hemorrhage, intracranial hemorrhage, gastric hemorrhage, gastrointestinal bleeding, etc., are all bleeding hurdles that ultra-premature babies may face. Once bleeding, it can not only put the baby at risk of death, but also lead to a poor prognosis.
- Feed off
The younger the gestational age, the more immature the stomach and intestines, and the more difficult it is to feed.
Fetuses born at 22 weeks of pregnancy are unable to even breastfeed, so they can only rely on external nutrient fluid inputs.
- The body temperature is turned off
Too thin skin, too little subcutaneous fat, and immature thermoregulatory centers can all cause ultra-premature babies to face severe body temperature barriers.
Every level is super difficult, life is different from the game, the game level can be repeated if you can't get through, but for young life, any level can't be overcome is the end.
2) There is a very realistic hurdle to face in the treatment of ultra-premature babies - the money barrier
Although money is insignificant in the face of life, money is a cruel but very real problem that many people need to face.
The cost of treatment of such an ultra-small gestational age premature baby born at 22 weeks of pregnancy is a huge expense for many people, not including the treatment of the sequelae of the subsequent ultra-premature baby.
2. The survival rate of ultra-preterm infants at 22 weeks of pregnancy is less than 10%.
Gestational age of birth is positively correlated with survival, with smaller gestational age being associated with lower survival.
Statistics show that under modern medical conditions, the survival rate of ultra-preterm infants born at 24 weeks of pregnancy is about 39%; The survival rate of fetuses born at 23 weeks of pregnancy drops directly to 17%, and the survival rate of fetuses born at 22 weeks of pregnancy does not exceed 10%.
Survival rates are also affected by medical conditions, with survival rates being even lower in areas where medical care is scarce.
Although there is continuous news of the successful treatment of ultra-small gestational age babies in China, there are still only a handful of successful cases of successful treatment of babies with a gestational age of 22 weeks and a gestational age of less than 22 weeks.
Even if a lot of manpower, material and financial resources are expended, it may only be a rescue, not a quality of life.
Even if the fetus survives at 22 weeks' gestation, the prognosis is not good
For ultra-premature infants with very small gestational age, the development of various organs and systems of the body is far from the mature stage, and even if they can survive, there may be deficits in intelligence, cognition, movement, vision, hearing, breathing and other aspects in the future.
- Studies have shown that after adjusting for factors other than gestational age (including gender, economic conditions, etc.), for preterm infants born at less than 34 weeks' gestational age, the IQ of school-age children decreased by 2.34 points for each week of gestational age.
- The incidence of cerebral palsy in preterm infants is much higher than that of normal fetuses, while the incidence of cerebral palsy in ultra-preterm infants is about 15%.
- Very preterm infants born at 22 weeks' gestation have more than 50% of the risk of moderate or higher neurodevelopmental impairment.
- Very preterm infants with a gestational age of less than 26 weeks have a more than 30% chance of developing subsequent ophthalmic disease.
- Very preterm infants with a gestational age of less than 26 weeks have a more than 30% chance of developing more than moderate cognitive impairment in the future.
To sum up, at 22 weeks of pregnancy, it is not recommended to give up the fetus by caesarean section when the fetus can no longer be preserved, and giving up may be the best choice.
