Biochemical tests of fetal well-being ('placental function tests') have been part of routine obstetric practice for more than twenty years. This book provides an overview of the current status of these tests - the physiological basis for their use, and their advantages and limitations in clinical practice. Considerable attention is given to interpretation, a subject which in the past has led to much confusion both in the scientific literature and in the minds of clinicians. Recent advances are described in detail, in particular the discovery of a whole new generation of placental products some of which offer great promise in the prediction of conditions, such as placental abruption and premature labour, which cannot be identified by any other current parameters. Finally, a set of clear recommendations is put forward for the choice of test in most of the common complications of both early and late pregnancy. The emphasis throughout is on how the basic biology of fetoplacental products dictates their use and interpretation in pathological conditions.
Already, the availability of placental function tests and fetal monitoring techniques have made significant inroads into the mortality rate from fetal distress. The question of fetal and neonatal morbidity carries far more serious ...

Now in its Eighth Edition, this leading comprehensive manual helps nurses deliver safe, effective, and informed care for patients undergoing diagnostic tests and procedures. The book covers a broad range of laboratory and diagnostic tests and studies that are delivered to varied patient populations in varied settings. Tests are grouped according to specimen and function/test type (e.g. blood, urine, stool, cerebrospinal fluid, etc.). Each test is described in detail, with step-by-step guidance on correct procedure, tips for accurate interpretation, and instructions for patient preparation and aftercare. Clinical Alerts highlight critical safety information.

Pathophysiology of Gestation, Volume II: Fetal-Placental Disorders covers important areas of reproduction such as maternal-fetal interrelationship, biochemistry and physiology of the fetoplacental unit, and use of amniotic fluid constituents as diagnostic tools for fetal well-being. This book is divided into five chapters. Chapter 1 deals with the disorders of placental transfer, clearly illustrating the physical and biochemical processes involved in placental exchanges between mother and fetus. The second chapter is devoted to disorders of placental endocrine functions. The various methods used for studying placental hormone production and the errors in analysis and interpretation of the results are also elaborated. The pathophysiology of amniotic fluid disorders is discussed in Chapter 3, while the genetic factors affecting growth and development from the gamete stage through fertilization and organ formation are described in Chapter 4. The last chapter considers the teratologic impact of the environmental factors on fetal growth and development. This volume is valuable to medical students and individuals concerned with the disorders of the maternal-fetal interrelationship.

In recent years there has been an enormous growth of interest in the proteins produced by the trophoblast and, most recently, the endometrium, since the knowledge of placental and endometrial proteins is essential for the understanding of the physiology of reproduction. This volume contains reports by 25 internationally renowned experts in this field presented at the 6th International Congress of Placental and Endometrial Proteins which was held in Nagoya, Japan, 1--3 December 1987. Additionally, these proceedings give a unique overview of research done in Japan by publishing over 70 papers by Japanese researchers.
