During labor, fetal movements (FM) and fetal breathing movements (FBM) continue in healthy fetuses. Fetal movements decrease as labor progresses, while fetal breathing movements remain constant, suggesting an autonomous nature.

Area of Science:

  • Obstetrics and Gynecology
  • Fetal Medicine
  • Perinatology

Background:

  • Limited data exists on intrapartum fetal activity.
  • Previous studies reported decreased fetal breathing movements during active labor.

Purpose of the Study:

  • To evaluate the normal pattern of fetal activity during labor.
  • To correlate fetal activity with fetal heart rate and neonatal outcomes.

Main Methods:

  • Real-time ultrasound monitoring of fetal movements (FM) and fetal breathing movements (FBM) during active labor.
  • Correlation of fetal activity with fetal heart rate (FHR) changes, cord blood pH, and Apgar scores.
  • One-hour recordings per patient.

Main Results:

Related Experiment Videos

  • Mean incidence of FM was 19.5%, FBM was 8.5%.
  • All FM associated with FHR accelerations; stronger movements correlated with higher accelerations.
  • FM decreased during labor; FBM remained constant.
  • All newborns had normal cord pH and Apgar scores.

    • Conclusions:

    • Fetal movements and breathing continue during labor in healthy fetuses.
    • Fetal movements decrease as labor progresses.
    • Fetal breathing movements remain constant, suggesting autonomy.
