If a pregnant woman revealed a syndrome Astana, it is necessary to listen to the advice of doctors that relate to childbirth. When the woman offered to perform the surgery of caesarean section, this means that the risk of injury to mother and baby if a natural childbirth is too large.

Injury

When a woman has a narrow pelvis or large fetus, and give birth naturally, there are risks of injury to baby and mother.

These include:

• Oxygen starvation (hypoxia);
• Dislocations and fractures;
• Curved neck;
• Infection of the child and mother;
• Bleeding in the brain or under the periosteum;
• Cephalhaematoma removed;
• Death.

Sometimes there is an early outflow of amniotic fluid due to the high location of the head of the fetus. During the separation of water from the uterus may withdraw a part of the umbilical cord or limb. When the baby starts to take human birthing, the umbilical cord is pressed and makes his way. If you pinch it that would be asphyxia, which can cause great harm and even lead to death. It is also possible infection of the fetus and the mother.

Narrow pelvis may deform the head and to tighten the process of childbirth. Due to the long labor and birth the woman will be weakened, and the baby can get stuck. In this case, there is hypoxia.

If the birth is delayed, and the fetus is in the birth canal too long, it can lead to poor circulation, which in turn will provoke a fistula.

When the delivery is long, it is possible the disruption of blood flow in the uterus and placenta. It can cause asphyxia, which will cause bleeding in the brain.

Such injuries could have a big impact on the health of the baby in the future.

Henkel-Astana symptom is determined on a 30–33 weeks pregnant, and every month until the birth nuzzled control. If the symptom is caused by improper position of the fetus in the uterus, that is, the probability that he will roll over, natural birth will be possible.
