Fetal Growth Abnormality Detection Trial Comparing Symphysis Fundal Height Alone Versus Symphysis Fundal Height with Point of Care Ultrasound Measuring Fetal Abdominal Circumference in Low-Risk Pregnant Women

What this Trial Is About

Researchers are evaluating how well symphysis fundal height (SFH) measurements alone compare to SFH combined with point of care ultrasound (POC-US) measuring fetal abdominal circumference (AC) for detecting small or large for gestational age infants among low-risk pregnant women after 35 weeks' gestation. The study aims to improve prenatal identification of abnormal fetal growth, which is linked to risks for mother and baby. This open-label, randomized trial is investigator-sponsored and focuses on low-risk pregnancies managed by midwives. Participants are randomly assigned to one of two groups: one group will have fetal growth monitored using SFH measurements alone, while the other will have SFH plus POC-US to measure fetal AC and assess amniotic fluid volume. Measurements occur at scheduled antenatal visits at 35-38, 40, 41, and beyond 41 weeks' gestation. If screening suggests abnormal growth or amniotic fluid levels, a formal obstetric ultrasound by a specialist will be performed. All women will have POC-US at 41 and 41+ weeks to check amniotic fluid, regardless of group. During the study, midwives will review medical histories, conduct physical measurements, and perform ultrasound assessments following the assigned method. Researchers will compare prenatal screening results to actual birth weights to identify small or large infants. They will also track the number of formal ultrasounds requested, cases of abnormal amniotic fluid, and maternal and neonatal outcomes. Participation lasts from enrollment at 35-38 weeks through delivery and initial postnatal assessment, about one year on average.
