INTRODUCTION: Estimated fetal weight is used routinely in the evaluation of the labor patient. Precise estimated fetal weight is necessary to provide adequate and accurate counseling to our patients. With the growing obesity epidemic, it is likely the clinical relevance of estimated fetal weight by Leopold's maneuvers is declining. The objective of this study was to test if estimated fetal weight by Leopold maneuvers or by ultrasonography is a more accurate assessment of delivery weight and if these measurements are affected by maternal body mass index (BMI).
METHODS: A retrospective chart review of 102 term gravidas presenting either in labor or for induction was conducted. Term pregnancies with both documented estimated fetal weight by ultrasound examination and by Leopold's maneuvers were included. Birth weight was recorded and compared with the estimates. Maternal height and weight at delivery were used to calculate BMI. SPSS was used for the analysis.
RESULTS: Estimated fetal weight by ultrasound examination and estimated fetal weight by Leopold's maneuvers differed significantly. Estimated fetal weight by ultrasound examination more accurately predicted actual birth weight with BMI greater than 30 kg/m.
CONCLUSION: Both ultrasound assessment and clinical estimation of fetal weight are strongly associated with actual birth weight. Ultrasonography provides a more accurate assessment of fetal weight in the term patient than clinical estimation by residents.
