Obstetrical care in the family medicine setting is an ever-evolving discipline. In addition to routine updates due to the passage of time, several new developments have occurred in the field since the last edition of this book was published. Among these developments are advances in prenatal assessment and diagnosis, recommendations for vaccination in pregnancy, assessment and management of infectious disease in pregnancy, and management of chronic disease concurrent with pregnancy. All thirty-one chapters of the second edition of this text have been thoroughly updated. Several chapters warranted substantive expansion and revision due to the developments on the topic. These chapters include preconception counseling, prenatal care, dysmorphic growth, preterm labor, recurrent pregnancy loss, infection, diabetes, postdates, normal labor, induction and augmentation, prolonged labor, fetal heart rate monitoring, routine postpartum and complications postpartum. A new chapterhas been added that covers vaccination in pregnancy as well as other routine wellness recommendations. Now in its fully revised and expanded third edition, Obstetrics in Family Medicine reflects the significant changes that have occurred in the field since 2015. This book remains the definitive resource for meeting the needs of a wide range of primary care providers who provide direct or indirect care of patients of childbearing age. This book also appeals to nurse practitioners, physician assistants and nursing personnel working in the primary care setting. Additionally, this book serves as a useful guide for medical providers who intersect with pregnant, or possibly pregnant patients including emergency medicine physicians, surgeons, EMT's and paramedics.
