AbstractToday obesity is accepted as an independent disease. The WHO describes obesity as an epidemic disease occurring worldwide and associated comorbidities affect all organ systems. Bariatric operations lead to an improvement or even complete remission of obesity-correlated comorbidities. Bariatric operations are conducted as restrictive, malabsorptive, or mixed procedures. The preoperative anesthetic evaluation of comorbidities is carried out with a special focus on preexisting impairments of cardiac and lung function (e.g. cardiomyopathy, obstructive respiratory dysfunctions). Extremely obese patients are at risk of aspiration. Airway management at anesthesia induction includes normal intubation or, if additional risk factors are present, either fiber optic awake intubation or rapid sequence induction. The pharmacokinetics of all applicable drugs are altered in extremely obese patients and they are at risk for developing postoperative thromboembolic complications with a high mortality rate. Therefore early and sufficient thrombotic prophylaxis is important.
