"Fetal GRowth AbnorMality DEtection Trial"

"Midwives perform a POC-US to measure the fetal abdominal circumference (AC) and evaluate the quantity of amniotic fluid.~In order to identify the appropriate sonographic plane the following markers need to be identified on POC-US~* Fluid filled fetal stomach on the left.~* Umbilical vein~* Umbilical portion of left portal vein within liver, as it meets the pars transversa (horizontal portion of left portal vein) seen as a right sided L or C shape.~* Fetal spine seen in cross section Amniotic fluid volume will be evaluated determining the deepest vertical pocket (DVP). Measurement is performed by assessing a pocket of maximal depth of amniotic fluid free of umbilical cord and fetal parts. The transducer is held perpendicularly to the patient's abdomen. The absence of a pocket measuring at least 2 cm in depth and 1 cm in width is indicative of oligohydramnios, while detection of a pocket measuring 8 cm or larger is suggestive of polyhydramnios (ACOG bulletin 175, 2016)."
