An understanding of critical care is vital to the modern surgeon, who is often responsible for patients requiring intensive care or high-dependency support. Key Questions in Surgical Critical Care has been designed as a companion to Surgical Critical Care, by Robert Ashford and Neal Evans, and is split into two main sections, multiple choice questions and viva topics. Based on the syllabus of the Royal College of Surgeons, each of these two sections is further subdivided into six sub-sections covering the cardiovascular system, the respiratory system, other systems and multisystem failure, problems in intensive care, principles of intensive care and practical procedures. The MCQs and viva topics provided are typical of those appearing in the MRCS examination, and the authors provide detailed explanatory notes to accompany each answer, almost all of which are cross-referenced directly to the relevant pages of Surgical Critical Care, as well as other sources of further reading.
