We aimed to study the association between three different methods of assessing the amount of amniotic fluid (subjective method (SM), deepest vertical pocket (DVP) and amniotic fluid index (AFI)) and estimated fetal weight (EFW) (in percentile or Z-score) after adjustment on maternal-fetal parameters. We performed a nationwide cross-sectional study through the French network of obstetric sonographers using the "flash" study method and including low-risk singleton pregnancies from 18-40 weeks. Crude and adjusted odds ratio were computed after stratification upon 2nd and 3rd trimester of pregnancy...

OBJECTIVE: To test the hypothesis that there is a higher rate of unsuccessful induction of labor (IOL) in post-term obese pregnant women compared to non-obese ones. METHODS: In this prospective cohort study, 144 obese (BMI > 30) and 144 non-obese (BMI < 29.9) post-term (> 41 weeks) pregnant women were recruited. IOL was done by misoprostol or amniotomy and oxytocin infusion according to the Bishop score. Comparison of percentage of failed IOL in both groups (primary outcome) was performed by the Chi-test...

OBJECTIVES: To assess whether in a cohort of patients with small for gestational age (SGA) foetuses with estimated fetal weight ≤10th percentile, maternal hemodynamics, fetal biometry and Dopplers at presentation, can predict the subsequent development of abnormal fetal Dopplers or delivery with birthweight <3rd percentile. METHODS: The study population comprised of 86 singleton pregnancies with SGA fetuses presenting at a median gestational age of 32 (range 26-35) weeks...

Objective of this randomized-controlled multicenter-trial was to determine whether the amniotic fluid index (AFI) or the single deepest vertical pocket (SDP) technique for estimating amniotic fluid volume is superior for predicting adverse perinatal outcome. Pregnant women at term were randomized in AFI or SDP group for assessing amniotic fluid at four unversitary hospitals. These two groups were not different with regards to primary outcome parameter (rate of postpartum admission to NICU), but concerning secondary outcome parameters: there were significantly more cases with the diagnosis oligohydramnios (9,8 vs...

The objective of this article is to present a new approach to diagnose and differentiate similar ventral masses by color Doppler. Two cases of ventral masses, a rare case of OEIS complex (Omphalocele-exstrophy-imperforate anus-spinal defects) with unusual presentation of exstrophy bladder and another of simple omphalocele, were studied by color Doppler for diagnosis and differentiation between the nature of similar masses. Ventral mass with absent bladder, normal kidneys, and normal amniotic fluid index raised the suspicion of exstrophy bladder...

Bisphenol A and phthalates are widely detected in human urine, blood, breast milk, and amniotic fluid. Both bisphenol A and phthalates have been suggested as playing a role in obesity epidemics. Exposure to these chemicals during fetal development, and its consequences should be concerning because they can cross the placenta. Thus, this study aimed to assess the association between prenatal exposure to bisphenol A and phthalates, and cord blood metabolic-related biomarkers. Maternal serum was used during the first trimester, to determine prenatal exposure to bisphenol A and phthalates...

Introduction: Oligohydramnios is described as decreased amniotic fluid volume relative to gestational age. Semiquantitatively it is described using the Amniotic Fluid Index (AFI) which is calculated by adding the depth in centimetres of the largest vertical pocket in each of four equal uterine quadrants. AFI less than or equal to 5 cm is defined as oligohydramnios. A Borderline Oligohydramnios (BO) is defined as AFI 5.1-8 cm. Aim: To assess the maternal and perinatal outcome of induction in borderline oligohydramnios cases at term...

BACKGROUND: Up to 40% of women gain excessive weight during pregnancy. Obesity complications and risks in parturient women undergoing cesarean section (CS) with different anesthetic methods remain unknown. This study aimed to assess the safety and risk of obese women undergoing CS delivery with various perioperative anesthetic methods. METHODS: Seven hundred ninety parturient women underwent CS under general anesthesia (GA), intraspinal anesthesia including epidural anesthesia (EA) and combined spinal-epidural anesthesia (CSEA)...

OBJECTIVES: The aims of our study were to assess the correlation between the amniotic fluid index (AFI) value and the frequency and type of fetal anomalies. MATERIAL AND METHODS: The material included 94 patients at the third trimester of pregnancy, 60 with mild polyhydramnios, 19 with moderate one, and 15 with severe one. Polyhydramnios was diagnosed if AFI was > 24 cm. All patients were divided into three groups based on the value of AFI: 1) mild polyhydramnios with AFI between 24...

Background Half-Fourier acquisition single-shot turbo spin-echo (HASTE) imaging is now widely used for placental and fetal imaging because of its rapidity and low sensitivity to fetal movement. If placental dysfunction is also predicted by quantitative value obtained from HASTE image, then it might be beneficial for evaluating placental wellbeing. Purpose To ascertain the most suitable magnetic resonance (MR) signal indexes reflecting placental function using HASTE imaging. Material and Methods This retrospective study included 37 consequent patients who had given informed consent to MR imaging (MRI) examinations...

OBJECTIVE: The aim of this study was to define the natural history of lower urinary tract obstruction (LUTO) with normal midgestational amniotic fluid volumes. MATERIALS AND METHODS: We performed a retrospective review of 32 consecutive patients with LUTO with normal midgestational amniotic fluid volume followed at 11 North American Fetal Therapy Network (NAFTNet) centers from August 2007 to May 2012. Normal amniotic fluid volume was defined as an amniotic fluid index (AFI) of ≥9 cm...

BACKGROUND: Approximately 1 in 10 pregnancies is affected by meconium passage at delivery, which can result in meconium aspiration syndrome (MAS). MAS can cause respiratory complications and, very rarely, death. Antibiotics have been prescribed for neonates exposed to meconium in amniotic fluid, with the intention of preventing infection due to potential bacterial contaminants. OBJECTIVES: We conducted this review to assess the efficacy and safety of antibiotics for:1...

REVIEW
Dawn S Hughes, Everett F Magann
The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...

OBJECTIVE: The purpose of this study was to assess the value of combining the estimated fetal weight (EFW) and amniotic fluid index (AFI) measured in term patients early in labor with intact membranes for prediction of macrosomia. METHODS: In a single center, prospective observational study, 600 patients in the first stage of labor before rupture of membranes in whom ultrasonography was performed to measure AFI and EFW, and these data were analyzed statistically to evaluate prediction of fetal macrosomia...

BACKGROUND: Amniotic fluid (AF) is one of the major determinants of fetal biophysical profile and can predict pregnancy outcome. Abnormal value of amniotic fluid index (AFI) may indicate fetal and maternal disorders. PURPOSE: To establish reference standards for AFI for this population after 28 weeks of pregnancy and evaluate the relationship between AFI, the estimated fetal weight (EFWT), and fetal gender. MATERIAL AND METHODS: A prospective cross-sectional estimation of AFI and FWT was done in 385 apparently healthy pregnant women in the gestational age range of 28-42 weeks...
