Abstract

Now-a-days assessing an accurate gestational age is considered to be a crucial factor to determine fetal growth and development. Ultrasonography is known to be a common non-invasive procedure to estimate fetal biometry at different gestational weeks. Though there were many studies emphasizing the correlation between gestation age (GA) using last menstrual dates (LMP) and ultrasonography (USG), the extended investigations in the same line may help to assess accurate method of gestational age estimation. Hence, the present study was aimed to understand and identify the correlation between gestational ages determined by LMP and USG using femur length from second trimester in the local pregnant population. The study was conducted on 504 ultrasonograms of healthier antenatal mothers. All the ultrasonography procedures were performed using ESAOTE-MY LAB 60 Machine equipped with 3.5 MHZ curvilinear transducer. Statistical analysis was conducted using SPSS software and linear regression analysis was performed to assess the interrelation of LMP and USG estimated gestational ages. The results of the study has exhibited the standard deviation of LMP and USG based gestational age as 7.8895 and 7.9775 respectively with significant P values (<0.001) and high degree of correlation (0.993). These findings has confirmed that LMP based estimation is more reliable than sonography estimated gestational age. Therefore, attention to LMP dates along with early week scanning may enable to identify an accurate gestational age and exact date of delivery. Thus, it would not only help to prevent preterm delivery but also assist to provide appropriate obstetric intervention.
