Treating acutely ill patients is one of the most demanding and stressful aspects of being a doctor. Most medical textbooks can only give general details about the treatment, and often the specific specialist advice needed to safely manage these patients is insufficient or patchy. The aim of this book is to provide a single source for doctors to access this information, to give them the confidence that they are treating their patients with the best, most modern treatments available, and to teach them a little on how and why the treatments are working.
