Summary

Thoroughly updated for its Second Edition,Fetal Monitoring Interpretationdescribes and illustrates the full range of patterns revealed by fetal monitoring and explains their clinical significance. The book uses case studies and high-quality tracings accompanied by detailed teaching diagrams usually found only in anatomical and surgical atlases.This edition includes twenty new case illustrations with teaching diagrams and five added tracings that present rare and unique patterns. The text incorporates the changes in terminology recommended by the 2008 workshop jointly sponsored by the National Institute of Child Health and Human Development, the American College of Obstetricians and Gynecologists, and the Society for Maternal-Fetal Medicine. Five new sections have been added: Pattern Transitions: Emphasizing the dynamic process of bedside assessment of the fetus, this section focuses on changes occurring over time, influenced by factors such as maternal health, pre-existing fetal health, gestation, and medications/anesthesia. Antepartum Monitoring: The first edition focused on intrapartum monitoring. The second edition presents a new section on the unique interpretation in the antepartum setting. Patterns Associated with Disease States and Other Conditions: For the first time, a section is included that begins with a maternal or fetal condition or the fetal environment and addresses potential fetal heart rate patterns that might be associated. Technology Behind Fetal Monitoring and Adjuncts to Fetal Assessment: This new section reviews adjunctive methods of fetal assessment that might improve on the monitor heart rate data in inconclusive situations. Medico-Legal Considerations: This section examines the role of the monitor in predicting or retrospectively assisting with the analysis of adverse neonatal outcomes and the future of the monitor in obstetrics.
