Abstract
Abstract: Accurate knowledge of gestational age is an essential prerequisite in an obstetrician ability to successfully manage the prenatal care of a patient and planning of appropriate therapy or intervention. The prospective observational study was done to evaluate gestational age by ultrasound measurement of CRL in the first trimester and HC, AC, and FL in the third trimester of pregnancy. A study population of 200 female pregnant women in the age range of 19 to 33 years of any gravid in the first and third trimester of pregnancy. The ultrasonographic examination comprised recording CRL in the 1st trimester and HC, AC and FL in the 3rd trimester of pregnancy and in the follow-up visits. The accuracy of CRL between 9 to 12 weeks of known menstrual age was 99%. While in the 3rd trimester, the accuracy of HC and FL from 34 to 37 weeks known menstrual age was 92%, while accuracy of AC from 34-37 weeks of known menstrual age was found to be 90% in the present study. So, it was found that CRL in the 1st trimester and HC and FL in the 3rd trimester found to be accurate for assessment of gestational age. The AC was found to be relatively less accurate in the prediction of gestational age by using real-time USG in the 3rd trimester.
