Spring of a newborn: when overgrown,what should be, why pulses, does not close

Update: December 2018

The birth of a child is a miracle not only in philosophical understanding. This and
technically a miracle. Nature has thought this process to such an extent
that for passing through the birth canal of the mother, the head of the child
able to decrease in size, to acquire an oblong shape and
flatten laterally.

This is facilitated by the presence of gaps between the bones of the skull,
filled with connective tissue plates. These are fontanelles,
condition, overgrowing and bulging which so often bothers
parents.

Despite, что их при рождении шесть, пять из них зарастают
so fast that many parents don’t even have time to learn about their
the existence of. All worries pass around the most noticeable fontanelle.
– frontal or large fontanelle (BR).

If the destination of the small fountains ended after birth,
then big in children continues to perform depreciation functions,
preventing fractures and injuries of the skull during falls and bumps.

When does the spring of a child close?

If your child is already a year old, and his spring is not overgrown,
no cause for concern. Normally this physiological process
ends in 1-1.5 years. If the timing of its closure to your baby
do not fit into the norm, then see a doctor. He will determine that
is this cause: a disease or developmental feature
baby

What should be the spring OK?

After giving birth, and also monthly when visiting a doctor,
a pediatrician assesses his condition, size, rate of decrease,
density of surrounding bones.

Normal size of the fontanel in a healthy, full-term baby is equal
2.5 – 3 cm, which is estimated by palpation and measurement
distances between opposite sides of the rhombus. Premature
children have a larger BR, about 3.5 to 3.5 cm. And large
children born on 41–42 weeks may have a smaller BR. Everything
this is a variant of the norm. By the way, the spring of a month old baby
may be somewhat more than at birth. This is due to
intense brain growth.

What should be the size of the BR at a certain age, say
just can not. Some sources indicate the following figures:

  • 1.8-2 cm in three months;
  • 1.8-1.6 cm in half a year;
  • 1.3-1.4 cm at 9 months;
  • 0.4-0.8 cm per year.

However, you can only focus on them approximately
insofar as:

  • All children initially different sizes (within normal limits).
  • The size of the spring does not affect the growth rate. Big can
    drag on a year, and a small one in 1.5 years.

However, all springs during the inspection should not be tense, not
bulging, to be at the level of the cranial bones. Permissible so that
the spring slightly sank or protruded, and also pulsed. Frontal and
parietal bones surrounding it should be dense, without areas
softening.

What to do if the spring does not close?

If by the age of 18 months the baby is still closed the spring,
you need to see a doctor. This may be the norm for your
child, and may be a symptom of a pathological condition.

may overgrow in 3 months. This is unusual, but if everyone else

If too big fontanel

Large BR is considered when sizes greater than 3.5 cm. This may be
normal in premature or immature babies. For the rest is required
консультация детского невролога и выполнение Brain ultrasound,
electroencephalogram to exclude hydrocephalus and elevated
intracranial pressure.

If the pulsation of the spring

Head мозг очень хорошо кровоснабжается, а сосуды его
are located close to the heart, so the blood in them flows under a large
pressure and with strong points. This pulsation is transmitted to the liquor,
on the membranes of the brain, on the plate covering the large spring of
children. Therefore, a small ripple is normal.

However, if the spring is pulsing strongly, then it can be
signal of disease. Other symptoms are usually present:
dehydration, diarrhea, intoxication, high fever, vomiting (see
frequent regurgitation or vomiting in infants). In this case, it is necessary
diagnosis and urgent treatment.

If the child has fallen spring

Decline of the fontanel (fallen) says about the dehydration of the child
or malnutrition. Fluid deficiency can occur on the background of:

  • heat waves;
  • overheating with strong wrap;
  • high temperature and intoxication;
  • with severe vomiting, diarrhea.

Lost fluid needs to be replenished. When overheating and
the temperature of the baby must be cooled and watering. When intestinal
infections, when drinking alone is not enough, the child will hold
invasive therapy in the hospital.

What does the bulging spring mean?

BR can emit (rises above the level of the surrounding bones
skull) on the background of intracranial pressure, which can be at
diseases such as meningitis, encephalitis, intracranial
bleeding, swelling, or for another reason. If, except for bulging
the following symptoms are observed, you should immediately call a doctor or
First aid:

  • Heat
  • Loss of consciousness
  • Vomiting, diarrhea in infants
  • Bulging after a fall or other head injury
  • Seizures (see causes of cramps in a child)
  • Strabismus
  • If bulging without other symptoms, but for a long time, also
    should see a doctor.

How to care for him?

Especially no action is needed. Despite,
that the connective tissue plate covering it is thin, it is in
durable as well. Therefore, when combing or inspecting the fontanel
doctor, nothing bad will happen. However zealous when
Scallop movements should not be done either. Child it may be
simply unpleasant. You can also not be afraid to wash your hair or cut
