Fetal breathing, fetal body movements, fetal heart rate, and fetal heart rate accelerations and decelerations were studied longitudinally in healthy fetuses between 24 and 32 weeks' gestation in the second and third hour following an 800 kcal maternal meal. The expected increase in fetal breathing following a maternal meal was not seen until fetuses were at(More)
Continuous 24-hour observations of fetal gross body movements were performed in 20 women between 24 and 28 weeks of gestation by means of real-time ultrasound examination. At 24 to 26 weeks, fetuses moved 13.1% +/- 0.3% of the time, which was not significantly different from the incidence of 12.4% +/- 0.8% at 26 to 28 weeks' gestation. An examination of the(More)
Maternal perception of fetal activity was studied in normal and at risk pregnancies from 24 weeks' gestation until term in the second and third hour after a maternal meal. The trend for the median number of maternally perceived fetal movements in the 2-hour observation period, across gestation, was similar to that previously reported in both maternally(More)
Continuous 24-hour observations of fetal breathing were performed in 20 normal, pregnant women between 24 and 28 weeks' gestation by real-time ultrasound. Fetuses made breathing movements approximately 14% of the time. No change in breathing activity after a maternal meal was observed, but a significant increase in the incidence of fetal breathing activity(More)
Brachial nerve stimulation at two frequencies (0.01 and 0.05 pulse per second, pps) with the fetus in either low-voltage electrocortical activity with eye movements or high-voltage electrocortical activity without eye movements was studied in five chronically catheterized fetal lambs at 130 to 140 days' gestation. During low-voltage electrocortical activity(More)
