A blood and marrow transplantation (BMT) is a procedure where abnormal blood-forming stem cells are replaced with healthy stem cells. The stem cells collected from circulating blood cells or from bone marrow are transferred from one person to another. This procedure is undertaken only after appropriate treatment. Nursing care of blood and marrow transplantation patients requires an additional set of skills such as knowledge of the side effects, both uncommon and common, assessment skills, treatment administration, and intensive care. This book is a compilation of chapters that discuss the role of nursing in blood and marrow transplantation. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. The topics covered in this book offer the readers new insights in the area.
