Book excerpt: Providing the inside track on how the experts approach and deal with real-world clinical scenarios, Challenging Concepts in Emergency Medicine selects specific challenging cases that are encountered in everyday clinical practice but do not have simple answers. A case-based guide to challenging areas in emergency medicine, this book covers the core and sub-specialty areas, in particular the often grey areas of intensive care and paediatric emergency medicine. Complex cases are comprehensively examined from a multidisciplinary perspective with detailed consideration given to management options and the contemporary evidence base behind these decisions. An effective revision aid for MCEM and FCEM and a reference during workplace-based assessments, Challenging Concepts in Emergency Medicine highlights critical information through the use of boxed features: 'Learning points', 'Clinical tips', 'Evidence base', and 'Future advances'. Each chapter has been reviewed by a national or international expert in the field and they have provided an 'Expert commentary', giving a unique insight into how today's opinion leaders confront and deal with the very same management challenges that all clinicians can potentially face on a daily basis. Containing summaries of current national and international guidelines, this book is ideal for continuing medical education and revalidation as well as for trainees preparing for examinations.
