[Mechanical ventilation of morbidly obese patients in anaesthesia and intensive care].

Sculptures from the Stone Age hint at the possibility that morbidly obese humans have always existed. Today, obesity represents a global epidemic with far-reaching consequences affecting health systems worldwide. Increasingly often, anaesthetists and intensivists are challenged with the treatment of extremely obese patients perioperatively. In addition to insufficient logistics and inappropriate technical equipment, the large number of obesity-related diseases, combined with the distinct pathophysiological changes of the respiratory system, put the morbidly obese patient at a significantly increased risk of perioperative complications. If, however, elaborate logistics and adequate airway management--followed by lung protective mechanical ventilation--are combined with appropriately conducted anaesthesia and intensive care, the morbidly obese patients' intensive care survival rates and hospital survival rates can be similar to those of patients of normal weight.
