Objective : To construct charts of fetal biometries at Sukhothai Hospital.
Materials and Methods : One hundred and fifty-one pregnant women attending the antenatal care clinic,
Sukhothai Hospital were recruited and received ultrasonographic examinations every four weeks until delivery.
Results : Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur
length (FL) were collected from 34 samples in each gestational age group. When comparing the results with
those from Western studies, all four fetal size parameters tended clearly to be lower. When comparing the
results with those from King Chulalongkorn Memorial Hospital, biparietal diameter, head circumference, and
femur length tended to be lower in the gestational age group of 36-40 weeks.
Conclusion : The construction of charts of fetal biometries in each region may be useful for obstetric manage-
ment.
