Regarding lUGR:: (A) Abdominal circumference (AC) is the least sensitive parameter for detection of lUGR, (B) In asymmetric lUGR head circumference/abdominal circumference (HC/AC) is reduced, (C) Serial biparietal diameter (BPD) is the only impoant measurement in lUGR, (D) Abdominal circumference is the most accurate measurement
Answer is D. Abdominal circumference is the most accurate measurement to predict IUGR. AC below 10th centile is used as a cutoff. AC should increase by at least 10mm in 2 weeks. AC is measured preferably at the level of the junction of the left and right poal veins,umbilical vein and as round as possible. TEXTBOOK OF OBSTETRICS, Sheila Balakrishnan,2nd edition, page no.205
