Vasten Symptom: Causes and Signs

Vasten's symptom is the ratio of the child's head to the woman's small pelvis. It is determined by the location of the head relative to the symphysis. Produce the definition manually. If the child's head protrudes and is above the symphysis, then the delivery by natural means is impossible.

The method of determining

The obstetricians determine Vasten's symptom with simple tricks.

1. The woman lies down on the couch and straightens her legs.
2. The doctor puts his hand with his fingers straight and starts to slide up to his stomach.

If the obstetrician rubs the palm of his hand against the elevation (the child's head), which protrudes from the top of the symphysis from above, this means that the head is not inserted into the pelvis. In this case, the mother is given a positive Vasten symptom.

If the palm ridge slides off the symphysis margin (from above), it means that the head of the child can enter the pelvis, and it is located below the symphysis. In this case, the mother is given a negative Vasten symptom.

If the palm of the palm moves unhindered, being in the same plane, it means that Vasten's sign is "level". The difference between a woman's pelvis and the child's head is quite small.

It is determined as shown in the photo.

Causes

The symptom of Vasten can provoke the following reasons:

• A large fruit;
• hydrocephalus;
• Asinclitic insertions (high and straight fusiform suture);
• Weak labor activity;
• A fetus in the pelvic presentation;
• Fetus in transverse presentation;
• Labor after 41 weeks;
• myoma;
• Scars on the uterus and vagina.

Types of delivery and degree of the syndrome

Depending on the degree, the birth can be natural, with the use of caesarean section and natural cuts along the edges of the birth canal.

• 1 degree. It is considered the simplest, in which you can give birth naturally.
• 2 degree. It is considered complicated, in which only a premature baby can be born naturally. If the child is full, then cutting the edge of the birth canal or a caesarean section is used. It depends on the size of the fetus and the width of the pelvis. The decision is made individually.
• 3 degree. It is considered difficult, in which it is impossible to give birth even to a premature baby in a natural way. The midwives perform a caesarean section.
• 4 degree. It is considered the most difficult, in which natural births are impossible.

If a woman has a narrow pelvis, then with a weight of more than 3 kg 600 g, only a caesarean section is performed.

If a woman in labor has been diagnosed with Vasten's syndrome, then it is necessary to heed the advice of doctors who deal with childbirth. When a woman is offered a cesarean section, this means that the risk of injury to the mother and child in natural childbirth is too great.

Possible injuries

When a woman has a narrow pelvis or a large fruit, and the birth is natural, that is, there are risks of injuring the child and the mother.

These include:

• Oxygen starvation of a child (hypoxia);
• Dislocations and fractures;
• Curvature of the neck;
• Infection of the child and mother;
• Hemorrhage to the brain or under the periosteum;
• Cephalohematoma;
• death.

Sometimes there is an early outflow of amniotic fluid due to the high location of the fetal head. During the passage of water from the uterus, a part of the umbilical cord or limb may exit. When the baby starts walking along the ancestral path, the umbilical cord presses and makes it difficult for him. If it is squeezed, then there will be asphyxia, which can cause severe harm and even lead to death. It is also possible to infect the fetus and the mother in childbirth.

A narrow pelvis can deform the head and tighten the process of delivery. Because of long bouts and attempts, the woman will weaken, and the baby can get stuck. In this case, hypoxia occurs.

If the labor is delayed, and the fetus is in the birth canal for too long, it can lead to blood circulation disturbance, which in turn will provoke the appearance of fistula.

When childbirth is prolonged, there may be a violation of blood flow in the uterus and placenta. This can provoke asphyxia, which will cause a hemorrhage in the brain.

Such injuries can greatly affect the health of the baby in the future.

Genkel-Vasten symptom is determined at the 30-33 week of pregnancy, and every month until the birth lead control. If the symptom is caused by an incorrect position of the fetus in the uterus, then there is a chance that when it overturns, natural births will become possible.
