Introduction:
The aim of the study was to carry out a quality control of fetal weight estimated by ultrasonography in an obstetric ward of a district hospital.
Materials And Methods:
The study comprised 105 scannings. The weight estimates were projected to the date of birth, and the difference in percentage between the actual birth weight and the projected weight was estimated.
Results:
There was a good agreement between the projected weight and the actual birth weight (r = 0.87). The mean value was -2.5%, and the standard deviation in the difference between the projected weight estimates and the actual birth weight, was 11%, which was consistent with findings in other studies.
Discussion:
Ongoing quality control of weight estimates and establishment of obstetric databases are recommended.
