Premature birth because of insufficient weight, so many organs may not be mature, premature babies have many complications, and the smaller the premature baby, these complications will be more, probably four more serious complications.
For example, breathing, which is the most important, because the lungs are immature, the smaller the lungs are more immature, after coming out may not breathe, the alveoli can not expand, called respiratory distress syndrome, if the old can not breathe, can not take the ventilator instead, may not be able to survive in the end, this is one of the most serious complications.
The second intracranial hemorrhage, premature babies are easy to occur, so like many children with cerebral palsy, in fact, one of the main reasons is related to preterm birth, the smaller the preterm baby cerebral palsy incidence may be higher.
The third infection, the preterm baby has poor resistance, causing systemic infection, sepsis may be more. The fourth more serious one is necrotizing enterocolitis.
These four should be very serious complications of premature babies, which may lead to non-survival. Premature babies have so many hazards, so we generally try to protect the fetus, when is it more assured? About 32 weeks or more, such premature babies these serious complications, may be with term children, statistically no difference, of course, not to say that there is absolutely no problem, statistically no difference, basically can be, so premature birth and fetal protection is generally towards this goal.
