[Anaesthesiological challenges in patients for bariatric surgery].

Anaesthesia of patients for bariatric surgery is a major challenge. It is essential to take into account the specific pathophysiology, comorbidities and related complications associated with obesity. An increased attention and an adequate monitoring during arousal from anaesthesia should be an integral part of the perioperative management. This article is designed to overview the anaesthesia-related pathophysiology of obesity. Based on this knowledge it is possible to estimate the perioperative risk situation for the obese patient. Furthermore, the following text presents concepts in performing anaesthesia for the pre-, peri- and postoperative phases and deals with some complications and their possible solutions.
