This module takes you through important aspects of 2nd trimester targeted scan. A systematic approach is essential for targeted scan to rule out fetal anomalies. Even though there is a shift in focus for anomaly scan from 18-20 weeks to 11-14 weeks, 18-20 weeks scan still remains the cornerstone to rule out anomalies. It outlines the importance of standardized performance, standardized documentation, uniform interpretation and analysis. It stresses the validity of “Rule of Three” approach. After a thorough analysis there comes the importance of documentation. Finally the Rule of Three is a method of systematic examination of the fetus. It helps us to know when to “stop” scanning. Checklist based approach reduces chances of missing anomalies. It also provides verifiable audit if any anomaly is missed.
Pregnancy dating is essential as it could help define the fetal growth, time prenatal testing and avoid pre and post term delivery. Accurate pregnancy dating is best done at the earliest as we will be seeing in this discussion the ultrasound accuracy to assess the gestational age reducing with advanced pregnancy. Following appropriate guidance in taking measurements is the most important step for dating the pregnancy.
The earliest measurement of gestational age taken in pregnancy should usually be accepted as the definitive assessment, subsequent examinations reflecting only fetal growth in the intervening period.
This course will give you an approach to obstetric ultrasound that is simple, systematic and efficient. Obstetric ultrasound involves not only looking for normalcy of the fetus but a comprehensive materno-fetal examination.
The main objectives of the course is to understand feasibility of detection of anomalies in the 1st trimester ,Identify common anomalies that may be seen in the 1st trimester and to understand limitations of 1st trimester anomaly detection.
The main objectives of this course are to understand principles of screening,Various terminologies commonly used in screening and learning the the importance of standardization.
Fetal growth is a continuous process occurring throughout the pregnancy. We can identify 4 periods of fetal growth.
- Pre conception
- Pre implantation
This module discusses these further and the fundamental principles in fetal growth assessment.
This module highlights the methodology for early pregnancy obstetric USG and identifying fetal anatomy upto 10 gestational weeks. This will help you to assess the viability of the fetus, number, determine the location and to assign the gestational age. With the availability of high resolution ultrasound probes, today we are able to evaluate the stages of embryological development of the fetus, designate this as Sono-embryology.
To understand and interpret sonoembryology better, we need a detailed knowledge of the stages of early fetal development. We recommend a brief reading of basic embryology up to 10 weeks prior to starting this module.
