What is surfactant used for in pregnancy?

Without surfactants, the small air sacs in your lungs (alveoli) would collapse. This would prevent oxygen from entering the bloodstream. In the last 3 months of pregnancy, your baby’s lung surfactants can freely pass into the amniotic fluid.

Why are lung injections given during pregnancy?

One “course” of antenatal steroid treatment usually consists of two injections given 24 hours apart. 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.

How does surfactant help premature babies?

Surfactant replacement therapy for premature babies acts to keep the alveoli from sticking together, and is supplemented with oxygen or ventilation to help the baby breathe. The majority of premature babies recover from RDS without major complications, while others are at risk for chronic breathing difficulties.

Why is surfactant important?

Function. The main functions of surfactant are as follows: (1) lowering surface tension at the air–liquid interface and thus preventing alveolar collapse at end-expiration, (2) interacting with and subsequent killing of pathogens or preventing their dissemination, and (3) modulating immune responses.

What is the name of injection for pregnancy?

Oxytocin injection is used to begin or improve contractions during labor. Oxytocin also is used to reduce bleeding after childbirth. It also may be used along with other medications or procedures to end a pregnancy. Oxytocin is in a class of medications called oxytocic hormones.

Will steroid injections make baby bigger?

Steroid injections given to mothers at risk of giving birth prematurely are linked to babies being born with lower body weights. In a study of more than a quarter of a million births, researchers found an association between steroid treatment – used to help an unborn baby’s lungs develop – and reduced birth weight.

Do steroid shots speed up labor?

Benefits and risks of corticosteroids for baby’s lungs. Some people go into labor very early. If you deliver before 34 weeks, receiving corticosteroid injections can improve your baby’s chances of doing well.

Why is surfactant given?

Introduction. Pulmonary surfactant is a complex mixture of phospholipids and proteins that creates a cohesive surface layer over the alveoli which reduces surface tension and maintains alveolar stability therefore preventing atelectasis.

At what gestational age is surfactant produced?

Surfactant is made by the cells in the airways and consists of phospholipids and protein. It begins to be produced in the fetus at about 24 to 28 weeks of pregnancy, and is found in amniotic fluid between 28 and 32 weeks. By about 35 weeks gestation, most babies have developed adequate amounts of surfactant.
