Zusammenfassung

Während der Cochleaimplantat(CI)-Operation ist eine audiologisch-technische Diagnostik notwendig, welche die technische Überprüfung der Funktion des Implantats sowie die audiologische Beurteilung seiner physiologischen Ankopplung an den Hörnerv bei elektrischer Stimulation beinhaltet, um im Bedarfsfall noch vor dem Ende des chirurgischen Eingriffs erforderliche Interventionsmaßnahmen treffen zu können. Die technische Funktionsprüfung umfasst die Kopplungsprüfung, die Implantatintegritätsprüfung sowie die Impedanz- und Feldtelemetrie, anhand derer die Funktion der Elektronik und der Elektroden des Implantats beurteilt werden. Die audiologische Diagnostik zur Beurteilung der physiologischen Funktion des Implantats beinhaltet die visuelle Erfassung der elektrisch evozierten Stapediusreflexe und die Messung der elektrisch evozierten Summenaktionspotenziale des Hörnervs einschließlich ihrer Reizschwellen.

Akuter Schwindel: Wann lohnt sich eine MRT?

28.04.2024 Schwindel Nachrichten

Akuter Schwindel stellt oft eine diagnostische Herausforderung dar. Wie nützlich dabei eine MRT ist, hat eine Studie aus Finnland untersucht. Immerhin einer von sechs Patienten wurde mit akutem ischämischem Schlaganfall diagnostiziert.

Bei schweren Reaktionen auf Insektenstiche empfiehlt sich eine spezifische Immuntherapie

Insektenstiche sind bei Erwachsenen die häufigsten Auslöser einer Anaphylaxie. Einen wirksamen Schutz vor schweren anaphylaktischen Reaktionen bietet die allergenspezifische Immuntherapie. Jedoch kommt sie noch viel zu selten zum Einsatz.
