Risk Of Neonatal Respiratory Distress Syndrome
Resp. distress syndr: Its caused by deficiency of surfactant that lines the airways&lung immaturity. From baby being premature vs genetic protein def. Varies in severity form baby to baby & some may require ventilatory support. Depends on gestational age from about 50% in babies born at 26–28 weeks, to about 25% at 30–31 weeks. Is more frequent in infants of diabetic mothers & in the second born of premature twins. ...Read more
Diabetes are at increased risk of developing the neonatal respiratory distress syndrome, is this true?
Lung development: It is true that high sugars can delay lung development in the developing fetus. ...Read more
Is it true that diabetes people are at increased risk of developing the neonatal respiratory distress syndrome?
Confusing wording: Infants born to diabetic mothers have a higher risk of respiratory distress. The long term higher maternal glucose levels tolerated by the fetus may impair their development of surface active agents in the lung that prevent RDS. These babies can develop RDS even if born on or after their due date. ...Read more
Premature lung: Prematures lack surfactant which is essential to keep alveoli expanded. This results in gradual collapse of more and more alveoli, (atelectasis) making it more difficult to oxygenate the blood. This becomes hyaline membrane disease or neonatal respiratory distress syndrome. ...Read more
Delivery by cesarean section is one of the predisposing factors of neonatal respiratory distress syndrome, why? And how?
??RDS??: I would agree more cs babies have respiratory pbs than regular delivery but the issue is ttn ( transient tachypnea of the newborn) not rds.A trip down the birth canal helps squeeze some of the lung fluid out before birth, which does not happen for cs. About 10% of cs will have to work hard to clear that fluid & may require o2 & special care in the process.It usually clears in < 48hr. ...Read more

General concerns and questions about newborn with respiratory distress syndrome in intensive care?
Prematurity: Leads to immature lunga with inadequate surfactant, a detergent that helps keep alveoli open. High o2 concentrations can cause retrolentil fibroplasoia leading to blindness. ...Read more
Not squeezed: Normal vaginal delivery squeezes some of the fluid in the lung spaces out during passage through the birth canal. C-sections alows that fluid to remain and thereby can cause a poor exchange of oxygen. Ttn uaually resolves on its own with supportive care. Ttn can also happen with a normal delivery but less often. ...Read more
Hx, Px,X ray: Rds is expected in premature infants or infants of diabetic mothers & emerges as increased work of breathing, need for oxygen & suggestive changes on xrays. There is some overlap of neonatal pneumonia, blood poisoning & rds symptoms & xrays so most are treated aggressively for all. Older kids can have a similar problem & the label is used when the pattern, xrays and o2 needs fit the pattern. ...Read more
When it happends: The frequency of respiratory distress tends to increase as the term of pregnancy decreases, reaching about 50% before 36 wks in males. It can occur in term babies, particularly diabetic mothers & I have seen some 30 wk premi's that never had it. Other conditions like lung fluid retention, amniotic fluid aspiration & neonatal pneumonia can have an identical presentation in the newborn period. ...Read more
