Venovenöse extrakorporale Membranoxygenierung
Publication History
Publication Date:
19 October 2017 (online)
Das ECMO-Verfahren zur Therapie des akuten Lungenversagens hat sich insbesondere seit der H1N1-Pandemie stark verbreitet. Der routinemäßige Einsatz erfordert jedoch eine sorgfältige Indikationsstellung, eine entsprechende Ausstattung und große Erfahrung.
-
Ziel der venovenösen extrakorporalen Membranoxygenierung (VV-ECMO) ist die Versorgung des Körpers mit ausreichend oxygeniertem Blut.
-
Indikationen zur VV-ECMO sind eine schwere Hypoxämie und/oder Hyperkapnie mit hohem Letalitätsrisiko.
-
Es gibt jedoch bislang keine gesicherten Vorteile der VV-ECMO gegenüber der konventionellen Therapie des ARDS.
-
Die VV-ECMO ermöglicht eine protektive Beatmung. Zur Frage der optimalen Beatmungsform gibt es keine Studiendaten.
-
Unter Sedierung ist auch bei ECMO-Patienten eine regelmäßige Beurteilung von Delir, Schmerz und Sedierung obligat. Zur ECMO ist jedoch nicht zwingend eine Sedierung erforderlich.
-
Technische Komplikationen sind selten, können aber gravierend sein. Die bei Weitem häufigste Komplikation unter ECMO ist die Blutung, die bei ca. der Hälfte der Patienten auftritt.
-
Eine ECMO sollten nur Intensivstationen einsetzen, welche die ELSO-Standards zur technischen und personellen Ausstattung erfüllen und über ein entsprechend geschultes Team verfügen.
