Ventilatorassoziierte Pneumonien und aktive Atemgaskonditionierung: Gibt es einen gesicherten Zusammenhang?

Zusammenfassung

Die aktive Atemgaskonditionierung steht bei vielen Anwendern in Verdacht, das Auftreten ventilatorassoziierter Pneumonien (VAP) zu begünstigen. Die Untersuchungen zu diesem Thema haben allerdings keinen eindeutigen Vorteil für die passiven Befeuchter gezeigt. Der Vergleich der sehr unterschiedlichen Studien wird durch den differenten Aufbau, die verschiedenen Gerätschaften und deren Einstellung erschwert. Trotzdem hoffen zahlreiche Intensivstationen durch den Einsatz von ausschließlich passiven Befeuchtern einen deutlichen Rückgang der VAP zu erreichen. Oftmals übersehen werden dabei jedoch negative Eigenschaften bzw. Kontraindikationen der auf den ersten Blick einfachen und kostengünstigeren passiven Befeuchtern.
