Growth-restricted human fetuses have preserved respiratory sinus arrhythmia but reduced heart rate variability estimates of vagal activity during quiescence.

The aim was to assess the association between fetal growth restriction (FGR) and fetal heart rate variability (FHRV) in relation to fetal movements. A prospective observational cohort study was performed. Non-invasive fetal electrocardiography (NI-FECG) allowed beat-to-beat assessments with <5% corrections of RR intervals.

Towards better reliability in fetal heart rate variability using time domain and spectral domain analyses. A new method for assessing fetal neurological state?

Objectives: Fetal heart rate variability (FHRV) has shown potential in fetal surveillance. Therefore, we aimed to evaluate the reliability of time domain and spectral domain parameters based on non-invasive fetal electrocardiography (NI-FECG).

Method: NI-FECG, with a sampling frequency of 1 kHz, was obtained in 75 healthy, singleton pregnant women between gestational age (GA) 20+0 to 41+0.

Home management by remote self-monitoring in intermediate- and high-risk pregnancies: A retrospective study of 400 consecutive women.

Introduction: Home management in general is considered to improve patient well-being, patient involvement and cost-effectiveness, for obstetric patients as well. But concerns regarding inclusion of intermediate- and high-risk pregnant women are an issue and a limitation for clinical implementation. This retrospective study evaluated the outcome and safety of extended remote self-monitoring of maternal and fetal health in intermediate- and high-risk pregnancies.

Fetal Heart Rate Variability Is Affected by Fetal Movements: A Systematic Review.

Fetal heart rate variability (FHRV) evaluates the fetal neurological state, which is poorly assessed by conventional prenatal surveillance including cardiotocography (CTG). Accurate FHRV on a beat-to-beat basis, assessed by time domain and spectral domain analyses, has shown promising results in the scope of fetal surveillance. However, accepted standards for these techniques are lacking, and the influence of fetal breathing movements and gross movements may be especially challenging.

Decline in stillbirths and perinatal mortality after implementation of a more aggressive induction policy in post-date pregnancies: a nationwide register study.

Introduction: In 2011 Danish national guidelines were changed towards a more aggressive induction and fetal surveillance policy from (1) induction of labor at gestational age (GA) of 42  weeks and (2) no fetal surveillance after 40  weeks to (1) induction of labor between 41 and 41  weeks, (2) earlier induction at 41  weeks in the case of maternal age >40 years or body mass index (BMI) >35 kg/m and (3) fetal surveillance at GA 41  weeks.

Material And Methods: This national cohort study included all pregnancies that reached 41  weeks of gestation in 2008-2014 (n = 102 167). Multivariate logistic regression analyses were used to estimate risks in the years after (2012-2014) vs.

Pregnancy-associated plasma protein A levels and neonatal complications in post-date pregnancies.

Objectives: To assess the association between serum pregnancy-associated plasma protein A (PAPP-A) and free β-human chorionic gonadotropin (free β-hCG) in the first trimester and perinatal complications in post-date pregnancies.

Methods: A total of 4948 women, who delivered after 40 gestational weeks, were included. Labour was not induced routinely until 42 weeks.
