Now completely revised and updated, this comprehensive text covers all aspects of caring for the critically ill child. The clear, logical organ-system approach addresses development, function, disease, and treatment for each entity, and relates normal function, pathophysiology, and treatment to clinical problems. New chapters cover hemodynamic principles, diagnostic and therapeutic cardiac catheterization, congenital malformations of brain and spinal chord, gastrointestinal pharmacology, and a new section considers failure of organ systems.
