What is neonatal respiratory distress syndrome?
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 the usual care should pay more attention to infant care methods, and then by the small made up for you to talk about in detail about neonatal respiratory distress syndrome related introduction, and neonatal respiratory distress syndrome nursing methods.
What is neonatal respiratory distress syndrome?
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.
In convalescence, because of the decrease of pulmonary artery pressure, the left to right shunt at the catheter level is easy to occur, 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.
In general, the disease is serious on the second and third day after birth. As the synthesis and secretion of PS increase naturally on the third day, the disease will obviously improve on the third day. In severe cases, superficial breathing, irregular respiratory rhythm, apnea and limb relaxation were found. 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.
matters needing attention
Prevention of premature delivery: 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. Fetal lung maturation: fetal birth with premature delivery or gestational age at 24-34 weeks of pregnancy can be significantly reduced by 48 hour before birth to dexamethasone or betamethasone, the incidence rate and mortality of RDS.
