Neonatal respiratory distress syndrome symptoms?

summary

What is neonatal respiratory distress syndrome? Neonatal respiratory distress syndrome (NRDS) usually occurs in premature infants or infants with diabetes mellitus. After birth, due to lack of pulmonary surfactant, it leads to progressive atelectasis, dyspnea, respiratory failure and other dyspnea problems. If it can not be treated in time, it will lead to death. Therefore, the infants with NRDS after birth will not be treated in time, Parents in usual care should pay more attention to infant care methods, and then by the small make up for you to talk about the symptoms of neonatal respiratory distress syndrome?

Neonatal respiratory distress syndrome symptoms?

Symptoms 1. Most of them were normal at birth, and respiratory distress appeared 2-6 hours after birth (severe cases were immediately after birth), manifested as shortness of breath (> 60 / min), cyanosis, nasal fan, inspiratory three concave sign and obvious expiratory groan. Exhaling moaning is a protective response of the body. When the breath is *, the glottis is not completely opened, so that the gas in the lungs is retained and the alveolar collapse is prevented. Progressive aggravation of respiratory distress is the characteristic of this disease.

The second symptom is shallow breathing, irregular breathing rhythm, apnea and flaccid limbs. If respiratory distress occurs 12 hours after birth, the disease is generally not considered. Physical examination showed flat chest, decreased auscultation breath sound, and fine moist rales.

The third symptom is that the left to right shunt at the catheter level is easy to occur in the convalescent period due to the decrease of pulmonary artery pressure, that is, the arterial catheter is open. The symptoms included feeding difficulty, apnea, pulse flushing, increased or decreased heart rate, increased precordial pulsation, systolic or continuous murmur in the second intercostal space on the left edge of sternum, and heart failure in severe cases.

matters needing attention

Prevention methods 1. Prevention of premature birth: strengthen the monitoring and treatment of high-risk pregnancy and delivery; In order to determine the size of fetus and the maturity of fetal lung, we should accurately measure the top diameter of GR and the L / s value in amniotic fluid for those who want to undergo cesarean section or early delivery. Prevention two. Promote fetal lung maturity: the fetus who has to give birth or have premature birth at 24-34 weeks of pregnancy, before birth 48 hours before giving the pregnant muscle intramuscular injection of dexamethasone or betamethasone can significantly reduce the incidence rate and mortality of RDS. Prevention method 3. Prevention and application of PS: for premature infants with gestational age less than 28-30 weeks, we should strive to use PS routinely within 30 minutes after birth. If conditions do not allow, we should also strive to use PS within 24 hours.
