Neonatology is concerned with the care of newborn babies who are at some degree of risk. This may be due to a variety of causes including prematurity, oxygen deprivation, breathing problems, infection, or birth defects. This book was originally written to provide a textbook of neonatal medicine which is concise, yet presents background information and alternative methods of treatment where appropriate. The updated second edition has the same aim, and includes basic information about the physiology and development of the newborn. It will be of value not only to medical students and paediatricians in training, but also to neonatal nurses and midwives.
