Development of fetal movement--fetal heart rate coupling from 20 weeks through term.
This study documents the development of fetal heart rate (FHR) change in response to fetal movement (FM) in healthy fetuses from 20 weeks' gestational age through term. Thirty-one fetuses received 50 min of Doppler-based monitoring at 20, 24, 28, 32, 36 and 38-39 weeks. FHR and FM were continuously digitized. A coupling index was computed as the percentage of FMs associated with increases in FH...
متن کاملChanges in Doppler flow velocity waveforms and fetal size at 20 weeks gestation among cigarette smokers.
OBJECTIVES To compare umbilical and uterine artery Doppler waveforms and fetal size at 20 weeks between smokers and nonsmokers. DESIGN Prospective cohort study. SETTING Auckland, New Zealand and Adelaide, Australia. POPULATION Nulliparous participants in the Screening for Pregnancy Endpoints (SCOPE) study. METHODS Self-reported smoking status was determined at 15 +/- 1 weeks' gestation....
متن کاملPatterns of fetal heart rate response at ∼30 weeks gestation predict size at birth.
There is evidence that fetal exposure to maternal stress is associated with adverse birth outcomes. Less is known about the association between fetal responses to a stressor and indicators of fetal maturity and developmental outcomes. The purpose of the present study was to determine whether fetal heart rate (FHR) patterns in response to a startling stimulus at ∼30 weeks of gestation were assoc...
متن کاملPrenatal diagnosis of fetal hemivertebra at 20 weeks’ gestation with literature review
Hemivertebra is a rare congenital spinal malformation, where only one side of the vertebral body develops, resulting in deformation of the spine, such as scoliosis, lordosis, or kyphosis. We present the ultrasonographic features of a fetus with hemivertebra at 20 weeks' gestation confirmed by post mortem radiography and pathological examination. The prenatal literature on this disorder is also ...
متن کاملDevelopment of Fetal Movement between 26 and 36-Weeks’ Gestation in Response to Vibro-Acoustic Stimulation
BACKGROUND Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation. AIM The aim of this investigation was to assess fe...
