in comparison with a control group of 16 mothers , who received tocolytic and sedative medication and were on strict bedrest and another control group of 42 untreated patients , there was no difference in the 3 groups concerning the incidence of respiratory distress syndrome in premature infants , but there was a lower perinatal mortality rate of respiratory distress syndrome in the betamethasone treated group , than in the controls , possibly due to a milder course of respiratory distress syndrome disease by accelerating functional maturation of the fetal lung with betamethasone .
