This book is a pocket-sized, practical introduction and ready reference to focused ultrasound (USS) in the Emergency Department. USS is a safe, rapid imaging technique, however, it is only in recent years that its role has emerged in the field of Emergency Medicine. In this context, limited Emergency USS is used to answer very specific questions, such as the presence or absence of AAA (abdominal aortic aneurysm), or of free fluid (such as blood) in the abdomen after trauma. Unlike other imaging modalities (eg CT scan) it is a rapid technique that can 'come to the patient'. The book explains the indications for, and use of, limited USS. Importantly it also explains its limitations. * A practical guide to appropriate use of ultrasound in the emergency department. * Written by team of leading experts in the UK and Australasia. * A volume in the successful Made Easy series.
