specialty on the rise Borne of the need for respiratory support in the polio epidemics of the mid-twentieth century, ICM has evolved from an ad hoc extension of anaesthetic practice to one of the most rapidly growing and advancing areas of healthcare ICM is integral to the care of the seriously ill and injured patient, working in partnership with traditional medical and surgical specialties to deliver increasingly complex and ambitious interventions The significant decrease in morbidity and mortality associated with, for example, major trauma, severe sepsis, and acute severe asthma, owes much to the evolution of ICM as a specialty Additionally, ICM is key to perioperative medicine: complex, invasive surgical procedures that significantly derange physiology are only routinely survivable with high-quality, intensive, post-operative care Many patients previously deemed too frail to undergo life-prolonging surgery, can now expect a safe and smooth perioperative journey due to the expertise within the intensive care unit (ICU) The role of ICM extends beyond the walls of the ICU Mobile intensive care teams identify and support patients deteriorating on general wards This external role is not limited to the hospital: ICM has made large contributions to pre-hospital and transfer medicine Finally, a greater appreciation of the impact of critical illness on patients and their families has led to the development of rehabilitation and follow-up services within intensive care This necessitates a different range of skills amongst staff Not only is ICM increasing in terms of breadth of practice, it is increasing in its depth of understanding and complexity of intervention Consider respiratory failure as an example Over a relatively short period of time, simple bag-in-bottle ventilators have evolved into complex, multimodal systems with an array of adjustable parameters This technological advance has been accompanied by huge strides in the understanding of the pathophysiology of respiratory failure and how this is affected by positive pressure ventilation Various ventilation ‘strategies’ have come and gone Numerous adjunctive pharmacological therapies have been proposed And other forms of mechanical support, such as oscillation and extracorporeal oxygenation, have joined traditional ventilators This expansion in breadth and depth requires delivery by an expert multi-disciplinary team ICM has always relied upon the input of enthusiastic doctors, nurses, pharmacists, physiotherapists, dieticians, and other professionals But the explosion in scope of ICM has meant that, in many regions, on-job learning is no longer sufficient and formal training is either highly desirable or mandated Numerous professional bodies have formed to provide guidance and oversight; curricula have been developed, remarkably similar between regions in their content; and systems of assessment, to judge competency and ensure quality, have been introduced It is for professionals working through these programmes of training and undertaking these tests of competency that this book is intended xii Introduction The content of Revision Notes in Intensive Care Medicine is largely guided by the three major English language medical exams related to ICM: the Fellowship of the College of Intensive Care Medicine (FCICM), set by the college of Australia and New Zealand and undertaken by candidates from that region; the British Fellowship of the Faculty of Intensive Care Medicine (FFICM); and the European Diploma of Intensive Care (EDIC) We have sought to provide a broad overview of the curricula but with particular focus on those areas that appear to be common examination subjects (it should be noted that, at the time of writing, none of the authors have any role in the setting or assessment of these exams; our involvement has been solely as candidates or in supporting colleagues who are candidates) Despite the medical origins of this publication, we believe it to be highly relevant to the other professions The National Competency Framework produced by the British Association for Critical Care Nursing has many similarities to the medical curricula mentioned above; comparable critical care frameworks have been proposed for pharmacists In addition, many universities offer postgraduate ICM qualifications up to Masters level Revision Notes in Intensive Care Medicine would provide a useful companion to these programmes We have aimed to incorporate the ever-expanding evidence-base underpinning ICM practice We have not imposed any in-depth analysis of these papers Rather we have sought to contextualize what we believe to be the key papers, and would encourage readers to explore the original publications themselves and to draw their own conclusions regarding the quality and validity of the evidence Finally, we must acknowledge the changing face of medical education, in particular the rise in prominence of online resources, and consider the role of the book There are those who would argue that in the Internet age the book, less dynamic and less frequently updated than website resources, is of little or no use We would, however, (perhaps unsurprisingly) disagree The book provides a palpable structure to training, and a solid base upon which to build revision The vast majority of the content will not change: the principles of physics, physiology, and pharmacology are unlikely to be revoked prior to the next edition And whilst new evidence will emerge, new technologies will evolve, and existing practices will adapt over the lifetime of this book, these developments are best understood in the context of current understanding of the bigger picture Revision Notes in Intensive Care Medicine provides this base and context We wish all readers the very best in their training and careers, and welcome all feedback on this inaugural edition 450 Key papers TRICC Hebert PC, Wells G, Blajchman MA, et al A
