Abstract Objective. The aims of the present study were to establish reference ranges for growth estimated fetal weight (EFW) between gestational weeks 20 and 42 determine effect maternal factors. Methods. This prospective longitudinal was based on 634 low‐risk pregnancies a total 1799 examinations. Gestational age computed from last menstrual period. Head circumference, abdominal femur length measured using ultrasound, EFW calculated formula Combs et al. statistical analysis regression...
To assess whether anomalous cord insertion is associated with risk of complications in the third stage labor.A population-based study.Norwegian Medical Birth Register.All singleton births (gestational age >16 weeks and <45 weeks) during period 1999-2011 (n = 738,443 singletons). Deliveries by cesarean were excluded, leaving 628,680 vaginal deliveries for analyses.Calculation odds ratios labor (postpartum hemorrhage, manual delivery placenta, curettage) velamentous marginal logistic...
Objectives. Medical abortion was first introduced in Norway April 1998. The aims of this study were to assess the efficacy, side effects, and acceptability medical using mifepristone orally misoprostol vaginally a Norwegian population. Design. included 226 pregnant women with gestational age <63 days who requested nonsurgical during year hospital regimen. Methods. All received single dose 600 mg orally, followed at 48 hours by 800 μg vaginally. Treatment outcome complications principal...
Maternal height and weight have increased during the past 20 years, as has birthweight. The aim of present study was to establish new reference charts for gestational age (GA) assessment using fetal biparietal diameter (BPD) head circumference (HC), determine effect maternal factors on assessment.This a prospective, cross-sectional 650 healthy women with regular menstrual periods singleton uncomplicated pregnancies, recruited after written consent. BPD (outer-outer) HC were measured at 10-24...
Anomalous cord insertion is associated with increased risk of adverse maternal and perinatal outcome. Our aim was to study whether anomalous prelabor rupture membranes (PROM), preterm PROM (pPROM), long or short umbilical cord, time trend spontaneous birth (SPTB) insertion.A population-based register using data from the Medical Birth Register Norway including all singleton births (gestational age >16 weeks <45 weeks) during 1999-2013 (n = 860 465) calculate odds ratios (ORs) for PROM, pPROM,...
To test whether adding conditional growth centiles to size of estimated fetal weight (EFW) improves prediction adverse perinatal outcome in pregnancies with or at risk having a small-for-gestational-age (SGA) fetus.This prospective longitudinal study included pregnant women diagnosed an SGA (≤ 5(th) centile) fetus. They underwent serial ultrasound measurements and the final two were analyses for this study. The EFW was categorized into normal (> 10(th) abnormal before entering variables...
In 2006 WHO presented the infant and child growth charts suggested for universal application. However, major determinants perinatal outcomes postnatal are laid down during antenatal development. Accordingly, monitoring fetal in utero by ultrasonography is important both clinical scientific reasons. The currently used references derived mainly from North American European population may be inappropriate international use, given possible variances rates of fetuses different ethnic groups. has,...
Background. The aim of the present study is to establish new reference charts for gestational age assessment based on fetal femur length (FL), and ranges FL head ratios at weeks 10–25, determine effect maternal factors these charts. Methods. Six hundred fifty low‐risk women with regular menstrual periods singleton pregnancies were recruited a prospective cross‐sectional after obtaining written consent. FL, outer–outer biparietal diameter (BPD), circumference (HC) measured 10–25 gestation. We...
Conventionally, the pregnancy duration is accepted to be 280–282 days. Fetuses determined by ultrasound biometry small in early pregnancy, have an increased risk of premature birth. We speculate that higher rate preterm delivery such fetuses represents a pathological outcome not applicable physiological pregnancies. Here we test hypothesis low-risk pregnancies fetal growth (expressed size second trimester) itself determinant for with slower growing having longer pregnancy. analysed gestation...
In humans, fetal breathing movements affect blood velocities in the umbilical vein and artery, but it is not known whether respiratory activity associated with increased flow through placenta. We therefore tested this hypothesis present study.One-hundred ten women low-risk singleton pregnancies were each examined three times by ultrasound during second half of pregnancy. Fetal heart rate, artery velocity, diameter at placental end determined rest movements.Based on 330 observations obtained...
Based on the hypothesis that fetal breathing movements (FBM) enhance sections of circulation to meet needs gas transport, we studied effects FBM inferior vena cava (IVC), which transports blood with lowest oxygen saturation in body.One-hundred and ten women low-risk singleton pregnancies were included a longitudinal study during second half pregnancy. Inner diameter, peak systolic velocity time-averaged maximum measured IVC below ductus venosus outlet rest FBM. Volume flow pressure gradient...
Background: Maternal height and weight have increased during the past 20 years, as has birthweight. The aim of present study was to establish new reference charts for gestational age (GA) assessment using fetal biparietal diameter (BPD) head circumference (HC), determine effect maternal factors on assessment. Methods: This a prospective, cross-sectional 650 healthy women with regular menstrual periods singleton uncomplicated pregnancies, recruited after written consent. BPD (outer–outer) HC...
Abstract Background The African population is composed of a variety ethnic groups, which differ considerably from each other. Some studies suggest that variation may influence dating. aim the present study was to establish reference values for fetal age assessment in Cameroon using two different groups (Fulani and Kirdi). Methods This prospective cross sectional 200 healthy pregnant women Cameroon. participants had regular menstrual periods singleton uncomplicated pregnancies, were recruited...
Bone size is a determinant of bone strength and tracks in its percentile origin during childhood adolescence. We hypothesized that the ranking an individual's femur length (FL) established early gestation thereafter. Fetal FL was measured serially using 2D ultrasound 625 Norwegian fetuses. Tracking assessed Pearson correlation, generalized estimating equation model, by calculating proportion fetuses whose remained within same quartile. Baseline Z-score (weeks 10 to 19) later measurements...
The human yolk sac provides the embryo with stem cells, nutrients, and gas exchange. We hypothesized that more maternal resources, reflected in body size composition, would condition a larger sac, ensuring resources for growing embryo. Thus, we aimed to determine relation between early pregnancy size.This subsidiary study was embedded multinational World Health Organization fetal growth project included healthy women mass index of 18-30, reliable information their regular last menstrual...
Abstract Introduction Fetal biometry is used for determining gestational age and estimated date of delivery (EDD). However, the accuracy EDD depends on assumed length pregnancy included in calculation. This study aimed at assessing actual prediction based fetal head circumference measured second trimester. Material methods was a population‐based observational with following inclusion criteria: singleton pregnancy, dating trimester, spontaneous onset or induction ≥ 294 days gestation, live...
Previous studies suggested that head circumference (HC) predicts the date of confinement better than biparietal diameter (BPD). The present study aimed to prospectively test this assumption.A prospective including 4179 consecutive women attending second trimester routine ultrasound examination at 17-20 weeks gestation. Outer-outer BPD and HC were determined as average three repeated measurements. Twins excluded. Time delivery was noted, differences between predicted calculated with (based on...
