practice and has created a need for up-to-date textbooks in critical care In the United Kingdom, the creation of new intensive care exams is also driving the need for succinct and current information for clinicians training in this field Key Clinical Topics in Critical Care has been written to ensure full coverage of the specialty of intensive care medicine Topics are presented alphabetically, with cross references to other related topics to allow easy navigation Each topic provides a succinct overview of its subject, with reference to current key papers and guidelines in the field and including a further reading section at the end of the topic The topics have been written by well-established and new authors from across the globe They have created an invaluable reference for trainees working in critical care units, enabling them to obtain a full range of key information from a single text The book also provides a valuable revision resource for readers who are studying for exams in intensive care medicine or for the critical care elements of surgical, medical, emergency medicine and pre-hospital care exams It will also be of interest to critical care nurses who want to
