How do corticosteroids mature fetal lungs?
Betamethasone and dexamethasone cause an immature fetus’s lungs to produce a compound called surfactant.

Keeping this in consideration, how do steroids help mature fetal lungs?When pregnant women are given steroid injections, the medication travels to the baby’s body and lungs through their bloodstream. When used between 25 and 33 weeks of pregnancy, steroids can speed up the development of the baby’s lungs a lot. This gives many preterm babies a much better chance of survival.One may also ask, how long does it take for steroids for lung maturity in pregnancy work? Steroid treatment reduces the risk of lung problems for babies who are born early, particularly for those born between 29 and 34 weeks of pregnancy. Babies born more than 48 hours, but less than seven days, from the first dose of steroids appear to receive the greatest benefit. Similarly, you may ask, how does betamethasone mature fetal lungs? Antenatal betamethasone is primarily used to speed up lung development in preterm fetuses. It stimulates the synthesis and release of surfactant (2), which lubricates the lungs, allowing the air sacs to slide against one another without sticking when the infant breathes.At what week do fetal lungs mature?Immature Lungs – Most babies have mature lungs by 36 weeks of gestation. However, since babies develop at different rates, there are exceptions to this. If a mother and her health care provider know that the baby might be coming early, an amniocentesis may be performed to check the maturity level of the lungs.
