Williams Obstetrics 23rd Edition PDF
In this 23rd edition of Williams Obstetrics, we continue to emphasize the science-based underpinnings and evidence-based practices of our specialty. Most professional and academic organizations embrace these principles, and while some promulgate guidelines and recommendations, others provide funding for such investigations. Our policy is to cite these whenever possible. A major impetus for these studies comes from the Eunice Shriver Kennedy National Institute of Child Health and Human Development—also called the NICHD. For many decades, this Institute has supported basic and clinical research to improve healthcare for women and children. We especially rely on investigations performed through NICHD-sponsored Maternal- Fetal Medicine Units and Neonatal Units Networks. There is also fiscal support for young investigators in obstetrics and allied specialties that comes from a number of societies and organizations. Among others, these include the American College of Obstetricians and Gynecologists, the American Gynecological and Obstetrical Society, the Society for Maternal-Fetal Medicine, the Society for Gynecological Investigation, and the American Board of Obstetrics and Gynecology. A major objective of this book is to provide a convenient source that will aid the busy practitioner—those “in the trenches.” To this end, we summarize new data that has influenced evidence-based management to improve pregnancy outcomes. And while we cite numerous sources to accomplish this, we again mention some important caveats. For example, while we try to avoid—or at least soften—dogmatism that creeps into obstetrical practice, we often cite our combined clinical experiences drawn from large teaching services. We remain convinced that these are disciplined examples of evidence-based obstetrics.
Importantly, we do not represent that these constitute the sole method of management. To succeed in these self-imposed mandates, we have again added new editors with especial expertise in important areas to ensure accurate interpretation of recent scientific and clinical advances. To allow for this, two editors who have served with distinction for several editions of this book have passed their pens on to others. Dr. Larry Gilstrap has traded the Chair of Obstetrics, Gynecology, and Reproductive Sciences at the University of Texas-Houston Medical School to become Executive Director of the American Board of Obstetrics and Gynecology. Dr. Kathy Wenstrom has left the University of Alabama at Birmingham to become Chief of Maternal-Fetal Medicine at Brown University. We will miss them both and value their contributions. To fill their shoes, two associate editors have assumed their duties. Dr. Dwight Rouse from the University of Alabama at Birmingham continues to lend his expertise in many areas of obstetrics, maternal-fetal medicine, and epidemiology.
