The Effect of Increased Fio2 Before Tracheal Extubation on Postoperative Atelectasis

Abstract: For safety reasons, it is common to ventilate patients with 100% oxygen before tracheal extubation. This study demonstrates that this practice favors postoperative atelectasis.

“…8 However, in anesthetized patients, the evidence on the amount of N 2 needed is mixed: in one study, minimal atelectasis (13% of that seen with 100% 02) was reported when 20% N 2 , 80% 02 was used; 9 in another using 60% N 2 , 40% 02 after a vital capacity maneuver was shown to prevent postoperative atelectasis. 10 But in a different study, considerable postoperative atelectic reduction in vital capacity was evident in patients who had been given either 30% 02 or 80% 02.11…”

“…Zu diesem Zeitpunkt bestand kein signifikanter Unterschied hinsichtlich des PaO 2 zwischen den Gruppen. Ausgehend von Studien aus der Humanmedizin wäre zu erwarten gewesen, dass ein niedriger Sauerstoffgehalt wäh-rend der Allgemeinanästhesie durch die Verminderung von Resorptionsatelektasen zu einer deutlich besseren Oxygenierung in der Aufwachphase führt (Benoit et al 2002). Da dieses in der vorliegenden Studie am Pferd nicht nachvollzogen werden konnte, scheint hier die Resorption als Ursache für Atelektasenbildung und dadurch verminderte Oxygenierung nicht maßgeblich zu sein.…”

“…Portanto, para evitar essas complicações, baixas concentrações desse gás têm sido utilizadas durante a anestesia (Rothen et al, 1995;Benoît et al, 2002;Magnusson e Spahn, 2003). Além disso, quadros de hipercapnia são relacionados a essa alteração pulmonar (Luna, 2002), e é sabido que alterações na pressão parcial de dióxido de carbono no sangue arterial (PaCO 2 ) influenciam no eletroencefalograma (EEG) e no fluxo sangüíneo cerebral (FSC) (Mi et al, 1998).…”
