Final answer:
Betamethasone treatment between 24-34 weeks of pregnancy is beneficial in enhancing fetal lung maturity, reducing the need for supplemental oxygen, and decreasing the risks of respiratory distress syndrome and other preterm birth complications.
Step-by-step explanation:
The administration of Betamethasone between 24-34 weeks of pregnancy in cases of preterm labor provides several benefits. Betamethasone is a corticosteroid that can enhance fetal lung maturity, thus decreasing the risk of respiratory distress syndrome (RDS), a common complication in the premature infant. Premature infants often require supplemental oxygen due to undeveloped lungs. By increasing the production of surfactant, a substance that helps keep the air sacs in the lungs open, Betamethasone helps in reducing the need for this. Moreover, Betamethasone treatment can also decrease the risks of other preterm birth complications like intraventricular hemorrhage (bleeding in the brain), necrotizing enterocolitis (gut inflammation), and infections.
A positive feedback loop of hormones initiates labor. Progesterone plays a key role in maintaining pregnancy by inhibiting uterine contractions to prevent preterm birth. As levels of progesterone decrease in late pregnancy, labor can begin. However, during preterm labor, medical intervention with Betamethasone can help prepare the fetus for the external environment in case of an early delivery.
