[Antenatal administration of betamethasone. Effects upon neonatal blood glucose in premature infants (author's transl)].

This effect was studied in 23 preterm neonates at the age of 2--8 hours. Betamethasone was administered at a dose of 12 mg intramuscular once or several times before delivery. This glycemia was compared with the glycemia of 52 control preterm infants studied at the same period. In the control preterm neonates, the mean (+/- 1 S.D.) blood glucose level was 0.51 +/- 0.26 g/l versus 0.53 +/- 0.24 g/l in the preterm infants pretreated with betamethasone. The incidence of glycemia less than 0.30 or 0.20 g/l was not significantly different in the two groups. These data show that prenatal betamethasone therapy has no harmful or diserable effect on the neonatal glycemia of preterm infants.
