Estimation of Gestational Age for Sudanese in 2nd and 3rd Trimester

A descriptive-cross sectional study aimed to estimate gestational age in normal Sudanese pregnant women in order to develop a linear equation that can be used to estimate the GA based on ultrasound measurement. The data collected in Elragi Hospital (Khartoum) and Elribat teaching hospital from January 2016 to January 2017, 232 pregnant women in second and third trimesters were scanned by ultrasound machine Toshiba-power vision-6000. Ultrasound measurement was done for GA-LMP, BPD, fetal FL, and AC, which having mean SD of (29.96.7week), (72.416.5mm), and (54.515mm), (237.666.2mm) respectively. A strong direct correlation was noted between all parameters and GA-LMP (gestational age from the date of last mensuration).
