[Perioperative risk management of patients with obstructive sleep apnea].

Obstructive sleep apnea (OSA) has a relatively high prevalence of 3-7% in the general population in western industrialized countries. The prevalence is higher in older patients and in patients with cardiac or metabolic disorders. In the general surgical population patients with OSA are often unrecognized prior to surgery so that unexpected problems can occur due to the higher risk of airway collapse. Severe apnea can result even hours later and especially after surgery of the upper airway. Anesthesists and ear nose and throat surgeons are equally responsible for the perioperative surveillance. The article will show the importance of the preoperative identification of OSA patients and the perioperative risk management in the different risk phases apart from surgery. Although the importance of guidelines is very high there are no mandatory guidelines in Germany in contrast to the USA and the implementation should be given priority.
