Abstract
INTRODUCTION: Fetal growth restriction (FGR) is defined as an estimated fetal weight (EFW) METHODS: All singleton pregnancies at our institution were included that were diagnosed with FGR per Hadlock between 6/2014-5/2015. The EFWs were applied to the Fenton curve to reassess the diagnosis of FGR, as well as the number of abnormal umbilical artery Doppler (UAD) measurements, incidence of small for gestational age (SGA) neonates (birth weight RESULTS: A 77.3% reduction in FGR diagnosis was noted from 110 pregnancies identified by Hadlock to 25 pregnancies identified by Fenton. If the Fenton curve was applied, the number of iatrogenic deliveries for FGR would have been 19 (instead of 62) in the cohort (p=0.0243). There were no differences in the number of absent or reversed UAD identified, SGA deliveries, antenatal steroid administered or NICU admission. There were no stillbirths/neonatal deaths in our cohort. CONCLUSION: By applying the Fenton growth curve, the number of FGR diagnoses is reduced without a resultant increase in perinatal morbidity; additionally, the burden of antenatal testing, ultrasounds, and iatrogenic deliveries is also reduced.
