Breath — the basis of our life. Newborn human life begins with the first breath, but breathing problems can lead to serious complications, sometimes incompatible with life.
Why is the baby's lungs refuse to carry out its functions? Let us try to look into the depths of this vital organ and understand — that's what.
Our lungs are made up of numerous small sacs — alveoli. The total surface area is comparable to their football field. One can imagine how tightly packed in all the thorax. But to the alveoli perform its primary function — gas exchange — they should be flat. Spadenie prevents the alveoli special "grease" — Surfactant. The name comes from a unique material angiysky words surface— Surface andactive— Active, that is,
Surfactant — a unique complex of proteins, carbohydrates, and phospholipids. The synthesis of this material is the epithelial cells lining the alveoli — alveolocytes. In addition, this "grease" has a number of remarkable properties — it is involved in the exchange of gases and liquids through the pulmonary barrier to remove foreign particles from the surface of the alveoli, alveolar walls protection from oxidants and peroxide, to some degree — and from mechanical damage.
While the fetus is in the womb, his lungs are not functioning, but, nevertheless, they are quietly preparing for the future spontaneous breathing — to
What's going on?
Insufficient amount of surfactant in the lungs of premature infants leads to the fact that as you exhale the lungs as it slammed shut (falling), and the child has with each breath they re-inflate. It requires a lot of energy, as a result of force newborn depleted and develop severe respiratory failure. In 1959, American scientists
The clinical picture of the syndrome manifested primarily symptoms of respiratory distress, developing, usually at birth, or through
Mother care for rational and careful observance of protocols for infants with RDS survive up to 90 percent of young patients. Transferred respiratory
It is difficult to predict, will develop in the individual child RDS or not, however, scientists have been able to carve out a risk. Predispose to the development of the syndrome, diabetes, infection, and maternal smoking during pregnancy, mother, delivery by caesarean section, the birth of the second of twins, birth asphyxia. Also found that boys are affected more often RDS girls. Prevention of RDS is reduced to the prevention of preterm birth.
Diagnosis of respiratory
Mainstay of treatment for infants with RDS technology is "minimal touch" baby should receive only the absolutely necessary for him and manipulation procedures. One of the treatments for the syndrome — an intensive respiratory therapy, various types of mechanical ventilation (mechanical ventilation).
It would be logical to assume that once RDS is caused by deficiencies of surfactant, and then treat the syndrome to the introduction of this substance from the outside. However this involves so many restrictions and complexities that the active use of preparations of artificial surfactant started only at the end
