Antenatal corticosteroids for fetal lung maturation in threatened preterm delivery: indications and administration
Archives of Gynecology and Obstetrics,  Clinical Article

Surbek D et al. – The evidence to date is clearly against the routine administration of multiple antenatal steroid courses. In special clinical situations, a second course of betamethasone (“rescue course”) may be justifiable. Tocolysis during administration of steroids is not routinely indicated in the absence of contractions, cervical shortening or rupture of membranes.

Methods
  • The published literature (PubMed search), as well as the recommendations of other national societies, has been searched and taken into consideration for these recommendations.

Results
  • The standard regimen of antenatal corticosteroids involves a single course of 2 × 12 mg betamethasone administered intramuscularly within 24 h.
  • The administration of corticosteroids usually is performed between 24 and 34 weeks gestation.
  • However, under particular circumstances it may be beneficial even at 23 weeks and at 35–36 weeks of gestation.
