Intrapartum Estimation of Fetal Weight by Symphysiofundal Height Measurement
AbstractBackground: The derivation and utility of birth weight centiles based on symphysiofundal height measurements were presented in an earlier study.
Objective: To validate the usefulness of intrapartum symphysio-fundal height measurements in fetal weight estimation.
Methods: A prospective study of a consecutive series of 4154 women who delivered at the University of Nigeria Teaching Hospital, Enugu from 1st April 2000 to 31st July 2002.
Results: Approximately 6.7 percent (279/4154) of the birth weights were below the 10th centile for the given symphysio-fundal height; 79.1% (3286/4154) were between the 10th and 90th percentile while the remaining 14.2% (589/4154) were above the 90th percentile.
Conclusion: Intrapartum symphysio-fundal height measurement is a useful alternative to ultrasonography in birth weight estimation in women in Enugu, Eastern Nigeria. Whether the technique applies equally well in other populations needs to be determined and is recommended.
