Now completely revised and updated, this comprehensive text/reference covers all aspects of caring for the critically ill child. Recognizing that children are not simply small adults, it discusses the differences between critical care of adults and that of children, exploring relevant structural and functional aspects, pathophysiology, and treatment of common diseases that afflict and critically injure children. Physiology, biochemistry, and molecular biology are all included, with an emphasis on clinically applicable information. The clear, logical organ-system approach includes development, function, disease, and treatment for each entity, and helps the reader relate normal function, pathophysiology, and treatment to clinical problems.
