Ultrasound Diagnosis of Fetal Macrosomia (large baby) Found Inaccurate

"Ultrasound-estimated fetal weight "is not very accurate, and we have to counsel patients on that, when they come to ultrasounds and they are worried that they are going to have this [enormous] monstrosity of a baby," lead investigator Dr. Alese Wagner said in an interview. "You can tell them [that] most of the time, we are off."'

"The mode of delivery was cesarean section in 66% of the pregnancies, compared with just 29% of all pregnancies in Calgary during the same period. "So it’s [more than] double, the percentage who are getting C-sections, on what is [an inaccurate weight]," said Dr. Wagner."
