Underestimation of fetal weight in premature rupture of membranes.
The accuracy of estimating fetal weight (EFW) by ultrasonographic techniques was analyzed after spontaneous premature rupture of the membranes (SPROM). The birth weights of 50 infants with SPROM delivered within 72 hours of ultrasound examination were compared with EFW based on ultrasonically measured parameters. The results indicate that EFW significantly underestimates birth weight in SPROM. The EFW based on biparietal diameter and abdominal circumference underestimated actual birth weight by an average of 12.4 per cent; EFW based on abdominal circumference alone, and on abdominal circumference and femur length, underestimated birth weight by 7.1 and 13.2 per cent, respectively.
