Detaillierte Beschreibung
Hypotonie nach Einleitung einer Allgemeinanästhesie, auch als postinduktive Hypotonie bezeichnet, ist bei Patienten mit nicht-kardiochirurgischen Eingriffen häufig und mit akuter Nierenverletzung assoziiert. Risikofaktoren für postinduktive Hypotonie sind höheres Alter, höherer ASA-Status (American Society of Anesthesiologists), chronische arterielle Hypertonie und höhere Dosen vasodilatierender Anästhetika. Es ist vernünftig anzunehmen, dass eine sorgfältige anästhesiologische Betreuung zur Aufrechterhaltung der Blutdruckstabilität beitragen und postinduktive Hypotonie begrenzen kann. Im Einklang mit dieser Annahme hilft die kontinuierliche Blutdrucküberwachung mit einem arteriellen Katheter während der Einleitung der Allgemeinanästhesie Klinikern, postinduktive Hypotonie zu reduzieren – und wird daher bei nicht-kardiochirurgischen Patienten mit Risiko für hypotoniebedingte Komplikationen empfohlen.
Neben der kontinuierlichen Überwachung verabreichen Anästhesisten routinemäßig Vasopressoren – wie Noradrenalin – zur Aufrechterhaltung des Blutdrucks. Noradrenalin ist ein schnell wirksamer Vasopressor mit kurzer Halbwertszeit und wird während der Einleitung der Allgemeinanästhesie üblicherweise als wiederholte manuelle Bolusgaben verabreicht. Als Bolus verabreicht, erhöht es den Blutdruck effektiv und schnell. Allerdings müssen Bolusgaben häufig wiederholt und gut getimt werden, um die Blutdruckstabilität zu gewährleisten.
In einer randomisierten Single-Center-Studie haben wir gezeigt, dass die kontinuierliche – im Vergleich zur Bolus- – Verabreichung von Noradrenalin während der Einleitung der Allgemeinanästhesie die Blutdruckstabilität bei Hochrisikopatienten mit nicht-kardiochirurgischen Eingriffen aufrechterhält. Wir möchten nun die Hypothese testen, dass die kontinuierliche – im Vergleich zur Bolus- – Verabreichung von Noradrenalin während der Einleitung der Allgemeinanästhesie postinduktive Hypotonie bei Hochrisikopatienten mit nicht-kardiochirurgischen Eingriffen reduziert, die eine kontinuierliche Blutdrucküberwachung mit einem arteriellen Katheter haben.

Experimental: Kontinuierliche Noradrenalin-Administration
Bei Patienten, die einer kontinuierlichen Noradrenalin-Verabreichung zugeordnet sind, wird Noradrenalin kontinuierlich über eine Spritzeninfusionspumpe verabreicht.
|
Bei Patienten, denen eine kontinuierliche Verabreichung von Noradrenalin zugewiesen wurde, wird eine Spritzeninfusionspumpe vorbereitet und mit einem peripheren oder zentralen Venenkatheter verbunden.
Der verantwortliche Anästhesist wird die Noradrenalininfusion starten und die Infusionsrate nach Bedarf anpassen und kann bei Bedarf zusätzliche Noradrenalinbolusgaben über die Spritzeninfusionspumpe verabreichen.
|
|
Kein Eingriff: Bolus-Noradrenalin-Verabreichung
Bei Patienten, die manueller Bolus-Noradrenalin-Verabreichung zugewiesen sind, wird Noradrenalin manuell in Bolusdosen verabreicht.
