Clinical Trial Summary

This study shall investigate the feasibility of prehospital performed trans-esophageal echocardiography in out of hospital cardiac arrest. The investigators will include ten patients undergoing advanced life support in this study and determine if it is possible to acquire adequate trans-esophageal images within 10 minutes after arrival of the study team on scene.


Clinical Trial Description

Out of hospital cardiac arrest (OOHCA) remains a leading cause of death in Austria. Current guidelines recommend to address potentially reversible causes for OOHCA early to improve survival and some of these causes can be recognized using echocardiography. The usefulness of trans-thoracic echocardiography during OOHCA seems to be limited as image acquisition may prolong now flow time and image quality is variable. These limitations might be overcome with trans-esophageal echocardiography. The investigators will investigate the feasibility of prehospital performed trans-esophageal echocardiography in ten OOHCA patients undergoing advanced life support. In addition to routine care by paramedics and emergency physicians, a dedicated expert in emergency ultrasound will perform trans-esophageal echocardiography in these patients. Primary outcome parameter: Is it possible to obtain trans-esophageal images of the heart within 10 minutes after arrival of the study team? ;
