Perioperative echocardiography

Abstract

Over the past decades, echocardiography has undergone a continuous evolution in technology that has promoted its clinical application and acceptance throughout perioperative medicine. These technological advances include improvements in transducer development that permit superior imaging quality and a wider selection of probes for epicardial, epiaortic, and surface echocardiography which can also be used in conjunction with multiplane transesophageal echocardiography. Moreover, the addition of Doppler technology and digital acquisition has secured the role of echocardiography as a valuable and relatively noninvasive diagnostic tool for the assessment of cardiovascular disease and hemodynamic monitoring throughout the perioperative period. Therefore, it has become increasingly important for perioperative physicians to understand the basic principles and underlying fundamental concepts pertaining to the technology and physics of echocardiography, as well as its inherent limitations. The current review outlines the modes and applications of different echocardiographic techniques used in perioperative echocardiography including M-mode, two-dimensional echocardiography, and Doppler assessment of blood flow. In addition, the limitations of these techniques and typical artifacts associated with the perioperative use of echocardiography are described.

In welcher Weise sollte ein Anästhesist sonographieren können?

“…Das Er lernen einer korrekten Untersuchungs technik entsprechend den Anforderun gen der "Basisfächer der Sonographie" ist in diesem Sinne essenziell. Eine sehr aus führliche Beschreibung der technischen Grundlagen der perioperativen Echokar diographie lässt sich bei Nowak et al [58] nachlesen.…”
