Key ResultSerial recording in 45 low risk fetuses throughout the second and third trimesters showed that hiccups were the predominant diaphragmatic movement before 26 weeks' gestational age and that there was a significant negative correlation with gestational age. There was a pronounced reduction between 24 and 26 weeks, which was the result of a decrease in the number of episodes of hiccups rather than a change in the duration of episodes.

TLDR
From 28 weeks onward, the mean fetal heart rate increased with hiccups reaching statistical significance at 32 weeks, andfetal heart rate variability was unaffected by hiccup until 36 weeks, at which time it decreased during hiccup periods.

TLDR
The duration of a fetal hiccup bout did not change after 28 gestational weeks; however, incidence slightly decreased from an early to a late group.
Magnetographic assessment of fetal hiccups and their effect on fetal heart rhythm.
TLDR
The present paper provides the first evidence of non-invasive biomagnetic measurements of the diaphragm spasmodic contractions associated with fetal hiccups, and demonstrates that fetal biomagnetometry can provide insights into the electrophysiological mechanisms of diaphRAGm motor function in the fetus.
Continuation of normal neurobehavioural development in fetuses with absent umbilical arterial end diastolic velocities
TLDR
It is concluded that prenatal neurobehavioural development may continue apparently unimpaired in the presence of absent umbilical artery end diastolic velocity of several weeks duration.
Effects of Antenatal Thyrotropin-Releasing Hormone on Fetal Heart Rate and Breathing Movements
TLDR
Maternally administered thyrotropin-releasing hormone as used to enhance fetal lung maturation has no clinically significant direct effect on FHR or FBM patterns.

FETAL BREATHING MOVEMENTS AND LUNG HYPOPLASIA: PRELIMINARY HUMAN OBSERVATIONS
TLDR
It is concluded that FB does occur in cases of oligohydramnios associated with lung hypoplasia, and it is therefore unlikely that lung Hypoplasia is merely the result of absent FB.
The predictive value of fetal breathing movements in the diagnosis of preterm labour.
TLDR
Two of the fetuses with false negative results showed a distinct breathing pattern different from the rest of the study group, which suggests that pattern recognition of fetal breathing might improve the specificity of this investigation.
Fetal breathing movements: antepartum monitoring of fetal condition.
TLDR
The combination of heart rate and fetal breathing assessment has produced a significant improvement in differentiating the normal from the compromised fetus and the quantitation of the magnitude of risk will become increasingly more precise.
