“…Atelectasis can occur following non-surgical procedure under deep sedation, such as endoscopic resection. However, previous studies have focused on perioperative atelectasis performed under general anesthesia [11][12][13][14]. Few focused on endoscopic procedures performed under deep sedation.…”

“…Es wurde spekuliert, dass sich durch die Anwendung einer niedrigeren F I O 2 das Risiko für die Entstehung von Atelektasen reduziert [65]. In diesem Zusammenhang konnte gezeigt werden, dass die Bildung von Resorptionsatelektasen nicht nur vom Ausmaß der Hyperoxie abhängt, sondern dass dieses Phänomen außer-dem noch durch die Dauer der Präoxyge-nierung beeinflusst wird [19]. Trotz mehrerer Studien scheint die optimale F I O 2 für Narkoseeinleitung und -ausleitung noch nicht endgültig gefunden zu sein.…”

Oxygen (O(2)) is the most frequently used pharmaceutical in anesthesiology and intensive care medicine: Every patient receives O(2) during surgery or during a stay in the intensive care unit. Hypoxia and hypoxemia of various origins are the most typical indications which are mentioned in the prescribing information of O(2): the goal of the administration of O(2) is either an increase of arterial O(2) partial pressure in order to treat hypoxia, or an increase of arterial O(2) content in order to treat hypoxemia. Most of the indications for O(2) administration were developed in former times and have seldom been questioned from that time on as the short-term side-effects of O(2) are usually considered to be of minor importance. As a consequence only a small number of controlled randomized studies exist, which can demonstrate the efficacy of O(2) in terms of evidence-based medicine. However, there is an emerging body of evidence that specific side-effects of O(2) result in a deterioration of the microcirculation. The administration of O(2) induces arteriolar constriction which will initiate a decline of regional O(2) delivery and subsequently a decline of tissue oxygenation. The aim of the manuscript presented is to discuss the significance of O(2) as a pharmaceutical in the clinical setting.

“…Macroscopically, atelectasis will be more easily produced during anesthesia and postoperatively when breathing hyperoxic gas (77,78). Thus, atelectasis is caused by absorption of alveolar gas, and oxygen is the gas that is absorbed the fastest since it is being consumed in the body.…”

ForumWorld Health Organization and the United States Center for Disease Control have recently recommended the use of 0.8 FIO 2 in all adult surgical patients undergoing general anaesthesia, to prevent surgical site infections. This recommendation has arisen several discussions: As a matter of fact, there are numerous studies with different results about the effect of FIO 2 on surgical site infection. Moreover, the clinical effects of FIO 2 are not limited to infection control.We asked some prominent authors about their comments regarding the recent recommendations

Oxygen concentration and characteristics of progressive atelectasis formation during anaesthesia

Abstract: formation of atelectasis after pre-oxygenation and induction of anaesthesia is oxygen and time dependent. The benefit of using 80% oxygen during induction of anaesthesia in order to reduce atelectasis diminished gradually with time.
