Results and consequences of routine ultrasound screening in pregnancy: A geographic based population study
Abstract
The aims of the study were:
To assess the risk for adverse obstetrical outcome in women where the EDD had been postponed more than 14 days with ultrasound.
To evaluate the mortality and morbidity of conservatively managed post-term pregnancies (gestation 294 days and beyond).
To assess the sensitivity for detecting fetal congenital anomalies with routine mid second trimester ultrasound performed in a routine clinical setting.
To estimate the random or biologic uncertainty of gestational age based on LMP and on routine ultrasound.
To compare the performance of the new Norwegian reference values for BPD measurement with the old reference values.
