Zusammenfassung

Eine wesentliche Herausforderung beim Erlernen ultraschallgestützter Interventionen, wie Perikardiozentese, stellt die Navigation der Nadel in einem dreidimensionalen Raum anhand eines zweidimensionalen Bilds dar. Um dies in vitro erlernen zu können, sind realitätsnahe Modelle erforderlich. Auf der Basis ballistischer Gelatine (12,6 %, 250 Bloom) wurde daher ein Simulationsmodell hergestellt, das die Punktion eines Perikardergusses ermöglicht. Dieser Perikardpunktionssimulator wurde zudem von 37 Anästhesisten in einem Prä-post-Modell subjektiv evaluiert. Die verwendeten Modelle erwiesen sich als technisch einfach herzustellen, strapazierfähig und realitätsnah. Sie werden daher in unseren Kliniken regelhaft zum Erlernen ultraschallgestützter Interventionen eingesetzt.

Abstract

An important challenge in learning ultrasound-assisted interventions, such as pericardiocentesis, is the navigation of the needle in a three-dimensional space on the basis of a two-dimensional image. In order to learn this in vitro realistic simulators are required. We manufactured a model which allows simulation of pericardiocentesis on the basis of ballistic gelatin (12.6%, 250 Bloom). Furthermore, the pericardiocentesis model was subjectively evaluated by 37 anesthetists in a pre-post design. The models used proved to be technically simple to manufacture, hard wearing and realistic. They are therefore regularly used in our hospitals to learn ultrasound-assisted interventions.
