Content: The third edition of the Color Atlas of Emergency Trauma brings the reader to the bedside of patients with traumatic injuries, at one of the largest and busiest trauma centers in North America. It includes over 1200 images, designed as a comprehensive visual and reference guide to emergency trauma care. Organized by major body regions, this atlas explores the full spectrum of common and uncommon traumatic injuries, including those caused by firearms, stab wounds, blunt trauma, crush injury, and burns. It also covers special patient groups, such as pregnant, pediatric and geriatric populations. Each chapter is augmented with patient images at presentation, radiographic, intraoperative and autopsy images, and color illustrations and photographs showing key anatomy from the cadaver laboratory. With common pitfalls discussed and invaluable tips from a multidisciplinary group of experienced trauma care providers, this book is a useful and practical resource for all those involved in trauma care.

Content: This full-color atlas presents nearly 700 images from the largest and busiest trauma center in North America. The images bring the reader to the bedside of patients with the full spectrum of common and uncommon traumatic injuries including motor vehicle accidents, falls, lacerations, burns, impalements, stabbings, and gunshot wounds. The clinical, operative, and autopsy photographs; X-ray, ultrasound, CT, MRI, and angiography radiographs; and original illustrations depicting injury patterns guide clinicians in recognizing, prioritizing, and managing trauma patients by using the physical cues paramount to the emergency setting. Organized by major body regions into separate chapters on the head, face, neck, chest, abdomen, musculoskeletal system, spine and soft tissue, the thorough text of this comprehensive atlas discusses management guidelines, emergency workup protocols, and common pitfalls. The Color Atlas of Emergency Trauma is an essential resource for those involved in trauma care.

Series Statement: Cambridge medicine

Content: Using high-quality intra-operative photos of fresh, ventilated and perfused human cadavers, this atlas of surgical techniques creates a unique new resource for trauma surgeons. The critical aspects of each surgical exposure and procedure are clearly demonstrated step-by-step in these realistic models, allowing the reader rapidly to understand technical key points which can be complex to describe. With more than 600 illustrations, it provides a highly visual summary of the critical anatomy, procedural sequencing, and pitfalls associated with trauma procedures. Informed by the editors' decades of collective experience in the field of trauma, in some of the busiest trauma centers in the world, the book is an invaluable quick reference for both common and uncommonly performed procedures. As such, it is ideal for trainee trauma surgeons, as well as those in civilian or military practice. Also of interest to trauma fellows and emergency medicine physicians.

Content: As surgical specialization becomes more focused, there is a growing lack of expertise amongst surgeons in life-preserving management of severely injured patients. This comprehensively updated second edition provides an in-depth, visual guide to both commonly and uncommonly performed trauma procedures. It includes over 900 high-quality color photographs and illustrations of step-by-step procedures on fresh, perfused and ventilated cadavers. Practical surgical anatomy, procedural sequencing, and common technical pitfalls are all clearly outlined. A number of new techniques have been introduced since the first edition, from REBOA (resuscitative endovascular balloon occlusion of the aortic), to ribplating for flail chest and skin grafting. Informed by the editors' experience in some of the busiest trauma centres in the world, the text has been updated throughout and includes additional photographs. This Atlas is an essential resource for trainee and operating trauma surgeons, and general surgeons distant from academic centres, as well as emergency medicine and critical care personnel.
