Many changes have occurred in veterinary medicine and anesthesia, with each succeeding edition of this definitive reference faithfully updating and documenting these advances. In recent years, the ever increasing emphasis on the treatment of animal pain has placed veterinary anesthesiology and pain management in a central role in the delivery of humane veterinary care. Accordingly, the increased importance of analgesia is highlighted in this new edition by the inclusion of several chapters focusing on recent advancements in animal pain management and most noticeably is reflected in its new title, 'Lumb & Jones' Veterinary Anesthesia and Analgesia'. This edition has 63 contributing authors, offering a wide breadth of author scientific training and clinical experience. As would be expected, many of the contributing authors are anesthesiologists but a number of new chapter authors are specialized in other clinical areas including clinical pharmacology, surgery, medicine, critical care, cardiology, neurology, urology, ophthalmology, dentistry, radiology, physical rehabilitation, and lab animal medicine. This increased diversity in authorship provides an even more comprehensive perspective to the management of anesthesia and pain in patients suffering from an array of clinical conditions and disease. Covering all veterinary species and a full array of clinical conditions and diseases, 'Lumb & Jones' serves as the gold standard reference in veterinary anesthesia and analgesia.
