Read the chapters that correspond to the clinical context you will be in before your first day that week. It is important to parallel your studying to the clinical context you are in (e.g., reviewing normal labor while on L&D vs abnormal uterine bleeding while in clinic) to ingrain the concepts into your memory bank and complement your experiences with your attendings and residents. This is a fantastic resource that provides a clear, broad overview of high-yield concepts. To begin, I recommend starting with First Aid for the OB/GYN Clerkship-order it before you begin your rotation. I studied throughout the entire block, which was six weeks at my medical school. When I was going through third year, I found that a systematic and multi-resource approach allowed me to cover all the content for the OB/GYN shelf exam. However, positioning yourself to score a top mark on the OB/GYN shelf exam is challenging because much of the content is specific and unique to this clerkship alone.

The information gathered by clinical examination and ultrasound should be integrated into clinical decision making.Ĭardinal movements fetal attitude fetal descent fetal position mechanics of labor ultrasound.Ĭopyright © 2021 The Authors. Ultrasound offers a historically unique opportunity for noninvasive, dynamic studies of the mechanics of labor. We would argue that descent is the main purpose of the uterine powers and cardinal movements, a description of the rotational movements the fetal head and shoulders must perform to obtain descent. German and older English literature lists only 4 rotational movements as the cardinal movements and excludes engagement, descent, and expulsion. Anglo-American literature lists 7 cardinal movements, namely engagement, descent, flexion, internal rotation, extension, external rotation, and expulsion. The fetus negotiates the birth canal and rotational movements are necessary for descent. Electronic address: mechanics of labor describe the forces required for fetal descent, and the movements that the fetus must perform to overcome the resistance met by the maternal bony pelvis and soft tissue.
