What is neonatal respiratory distress syndrome?

summary

Most of them are preterm infants, whose crying can be normal at birth, and dyspnea occurs within 6-12 hours, gradually aggravating, accompanied by groans. Irregular breathing with intermittent apnea. The complexion becomes gray or cyan due to hypoxia, and cyan is obvious after right to left shunt. What is neonatal respiratory distress syndrome? Next, I'd like to share my views with you.

What is neonatal respiratory distress syndrome?

Neonatal respiratory distress syndrome refers to the symptoms of progressive dyspnea and respiratory failure soon after birth. It is mainly caused by the lack of alveolar surfactant, which leads to progressive collapse of alveoli. Within 4-12 hours after birth, children have progressive dyspnea, groan, cyanosis and inspiratory three concave syndrome. In severe cases, respiratory failure occurs. The incidence rate is related to gestational age. The smaller the gestational age, the higher the incidence rate, the lighter the weight, the higher the mortality.

The incidence rate is related to gestational age. The smaller the gestational age, the higher the incidence rate, the lighter the weight, the higher the mortality. It mainly occurs in preterm infants, clinical to progressive dyspnea as the main performance, pathology to appear eosinophilic hyaline membrane and atelectasis as the characteristics, so also known as hyaline membrane disease.

Neonatal respiratory distress syndrome (NRDS) refers to the transient (minutes to hours) natural respiration after birth, followed by progressive dyspnea, cyanosis, moaning and other acute respiratory distress symptoms and respiratory failure. It is more common in premature infants, low birth weight infants or overdue infants. Hyaline membrane is the main pathological change in children's lung, so it is also called neonatal hyaline membrane disease.

matters needing attention

The combination of antenatal use of ACh for pregnant women and postpartum use of PS for newborns started relatively late, and the pregnant women had delivered within 24 hours; The RDS is often serious in newborns with severe intrauterine distress. Therefore, combined prevention is appropriate. Animal experiments show that combined prevention is better than single prevention.
