Obesity and, in particular, morbid obesity, now effects upwards of one third of the population of the Western world. Morbidly obese and super obese patients are no longer uncommon, and frequently present for anesthesia and surgery. Every practicing anesthetist is likely to be faced with such patietns, either in the elective or emergency setting. Because morbid obesity is frequently complicated by a number of potentially life-threatening comorbidities, and because of the technical and physical challenges involved in treating the morbidly obese, they represent an extremely high risk group of patients. The high level of concurrent disease in these patients as well as their altered physiology mean that standard anesthetic drugs, equipment and techniques may be sub-optimal or even inappropriate.This book provides a wealth of practical information and advice for the clinical anesthetist dealing with the overweight/obese patient. It also provides a summary of the basic principles of the physiology of obesity, enabling the clinician to arrive at sound solutions to complex clinical problems. This book does not aim to replace the major texts or research literature in the field, but should serve as a practical ready reference. Suggestions for further reading have been included at the end of each of the short, focused chapters.
