This book presents the latest evidence-based guidelines for perinatal management and is designed to help obstetricians and neonatologists minimize complications and offer patients the best possible care. Since 1960, there has been a significant increase in basic and clinical investigations on normal and pathological pregnancy in the developed world. This has provided insights into the physiopathology of pregnant women, fetuses and newborns and led to the development of new technologies, bringing about a new medical subspecialty: perinatal medicine. The book is divided into eight main sections: The first examines basic periconceptional care and discusses the ethical aspects of perinatology. The next section focuses on prenatal considerations, such as the nutritional aspects of gestation and puerperium, physical exercise during pregnancy, routine laboratory tests, prenatal care of multiple gestations and the role of the neonatologist in prenatal care.
