This 24th edition of Williams Obstetrics has been extensively and strategically reorganized. Primarily writing for the busy practitioner—those “in the trenches”—we continue to present the detailed staples of basic obstetrics such as maternal anatomy and physiology, preconceptional and prenatal care, labor, delivery, and the puerperium, along with detailed discussions of obstetrical complications exemplified by preterm labor, hemorrhage, hypertension, and many more.
Once again, we emphasize the scientific-based underpinnings of clinical obstetrics with special emphasis on biochemical and physiological principles of female reproduction. And, as was the hallmark of previous editions, these dovetail with descriptions of evidence-based practices. The reorganized format allows a greater emphasis on the fetus as a patient along with expanded coverage of fetal diagnosis and therapy.
These changes are complemented by more than 100 new sonographic and magnetic resonance images that display normal fetal anatomy and common fetal anomalies. Finally, to emphasize the “M” in maternal–fetal medicine, we continue to iterate the myriad medical and surgical disorders that can complicate pregnancy.
