Aims: To determine if preterm growth restricted fetuses benefit from antenatal corticosteroids.

Nine studies found evidence of fetal growth restriction with repeated doses of antenatal corticosteroids.

All the studies reported improvement in lung function after repeated doses of antenatal corticosteroids.

This study evaluates the timing of the first course of antenatal corticosteroids in clinical practice.

Eleven studies looked at the effect of repeated doses of antenatal corticosteroids on fetal growth.

However, the safety and efficacy of repeated courses of antenatal corticosteroids have not been adequately studied.

There were 8 studies that assessed the effects of repeated doses of antenatal corticosteroids on lung function.

Objective: Treatment of pregnant mothers with a single course of antenatal corticosteroids significantly reduces neonatal mortality and morbidity.

The optimal time interval between administration of antenatal corticosteroids and delivery is 1 to 7 days.

Objective: To evaluate the management of imminent preterm delivery with respect to prescription of antenatal corticosteroids (ACS) and referral to a tertiary center.

Study design: A retrospective study was performed for 609 mothers and their 713 infants who were treated with 1 to 12 courses of antenatal corticosteroids.

The Bill & Melinda Gates Foundation has committed $1.5 billion over four years to support interventions such as antenatal corticosteroids and to discover new ones.

Background: Antenatal corticosteroids (ACS) have long been regarded as a cornerstone intervention in mitigating the adverse effects of a preterm birth.
