| Abstract
Background & aim: The high incidence of deaths during delivery, is related to infant’s weight and problems linked to it. The estimation of fetal weight in managing of labor and delivery is very important. This study were compared the estimated fetal weight, abdominal circumference , femur length and birth weight by ultrasound in pregnant women.
Methods: This cross - sectional study was performed on 600 pregnant women who delivered singleton pregnancies referred to care during the years 1390 to 1391 in Imam Khomeini's Iran 72 hours before delivery. Patient data included gestational age, past medical history, estimated fetal weight, abdominal circumference and femur length and prenatal based on Hadlock equation and the neonatal weight was recorded. In case of non-delivery within 72 hours, the patient was excluded. Pearson correlation and chi-square test was used to compare proportions.
Results: Pearson correlation coefficients between weight estimate before programming the birth (0.878) and the actual weight at birth date, the weight under 2500 g,( 0.888), group weighing between 2500 to 4000 g, (0.816) and the group weighing more than 4000 g, (0.399) were measured. The mean absolute difference tof estimated weight and the actual weight before birth, after birth were determined in total (96.174 g). The mean difference between the estimated weight and the actual weight after birth in SGA fetus (small for gestational age ratio), 88/172 mg, infants weighing between 4000-2500 g 29/175 g and 4000 g in weight, 213.46 mg were determined
Conclusions: Validity of ultrasound 72 hours before delivery for fetuses weighing less than 4000 grams acceptable and for fetuses weighing 4000 g was relatively weak.
