title: Fetal breathing movements in high risk pregnancy.
abstract: In 12 normal and 50 high risk pregnancies fetal breathing and fetal trunk movements were measured by real time ultrasound after the mothers had been given oral glucose. Fetal breathing was significantly reduced in the two fetuses which subsequently died and in five of six fetuses developing fetal distress in labour. Two patterns of breathing were noted in 23 fetuses with cessation of Intrauterine growth: either reduced fetal breathing or almost continuous breathing. Fetal trunk movements were more variable than breathing movements and a reduction in trunk movements had less predictive value.
