Estimation of Gestational Age by Measuring Bi-parietal Diameter and Femur length In Second Trimester

ABSTRACT

This study was done in Khartoum North Teaching Hospital in the period first of April 2016 to September 2016 . The study was aprospective cross_ sectional research . The aim of the study to determine which is the better estimator of gestational age in the second trimester between femur length and bi-parietal diameter , The study population consisted of 50 normal pregnant women they were randomly selected in second trimester and Scan by real time ultrasound machine.

The data were analysed & the result of this study there was no significant difference between the mean of gestational age estimates from femoral length (FL) and bi-parietal diameter (BPD) , and also found that the avarage of BPD and FL is more accurate than the BPD or FL separately .

The study recommened that all pregnant women in second trimester must be follow up by US to confirm the GA and to evaluate expected date of delivery . To confirm E.D.D using avarage of FL & BPD rather than BPD or FL separetly. Using another different methods for measuring to estimate gestational age during pregnancy or in second trimester for pregnant women..
