摘要: Abstract Although prenatal glucocorticoid treatment reduces neonatal respiratory morbidity, distress syndrome and chronic lung disease (CLD) develop in many very-low-birthweight infants despite therapy. To investigate the effect of additional with thyrotropin-releasing hormone (TRH), we did a multicentre, blinded, randomised trial. 404 women threatened preterm delivery at less than 32 weeks' gestation received betamethasone plus TRH (4 doses 400 μg 8-hourly) or placebo. 103 who were fully treated 1 500 g birthweight evaluated during period. (55 infants) not affect total incidence (47% vs 58% controls) severe (13% 25% controls, p=0·11). CLD (defined as requirement for supplemental oxygen 28 days after birth) developed significantly fewer TRH-treated (18% 44% p
