First Trimester Ultrasound

Abstract Improvements in ultrasound technology, including transvaginal sonography and higher frequency probes, have led to a better understanding of early pregnancy development. These advances and the increasing availability of ultrasound allow women to have an earlier and more accurate assessment of their pregnancy. First trimester sonographic signs have been identified that can be used to reassure women that their pregnancy is progressing normally or counsel them that their pregnancy will fail. In addition, first trimester ultrasound can accurately predict the type of twinning in multiple gestations, allowing for appropriate counseling and management. Objectives Know the first trimester ultrasound findings of a normal intrauterine pregnancy Understand the ultrasound findings that diagnose an early pregnancy failure Know the ultrasound criteria used to diagnose a multifetal gestation

Introduction: The earliest proof of a viable pregnancy is obtained when cardiac activity of the embryo can be observed. Transvaginal sonography can accurately demonstrate embryonic heart rate at 6 weeks of gestational age by using M-mode transvaginal sonography. Slow embryonic heart rate at 6-7 weeks of gestational age is associated with high rate of first trimester pregnancy loss. AIM:  The study was aimed to evaluate the role of embryonic heart rate (EHR) of early pregnancies as predictive factor of adverse outcome at end of first trimester of pregnancy. Methods: This observational study was conducted in the Department of Obstetrics and Gynecology Zenana Hospital, SMS Medical College, Jaipur. It included 300 pregnant women between 6 weeks to 9 weeks of gestational age attending antenatal OPD. Embryonic heart rate was measured by transvaginal sonography. Embryonic heart rate was classified as slow, if it was fewer than 110 beats/ mint or outcome was measured as occurance of spontaneous pregnancy loss prior to 12 weeks. Results: Out of 300 cases, 290 (96.67%) had embryonic heart rate ?100 beats per minutes and 10(3.33%) had embryonic heart rate <100 beats per minutes. Out of these 290, (Embryonic heart rate ?100 beats per minutes), 284 (97.93%) had good prognosis and 6 (2.07%) had abortion. In 10 women (Embryonic heart rate <100 beats per minutes), 3 (30.00%) had good prognosis and 7 (70.00%) had abortion. This observation was statistically significant. Conclusion: Slow embryonic heart rate on ultrasonography reduced the success of pregnancy and may lead to abortion. Keywords: Embryonic heart rate, Ultrasonography, Early pregnancy loss
