简要总结
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.
详细描述
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?

入选标准
- •adult patients undergoing advanced life support for out of hospital cardiac arrest
排除标准
- •patients who should undergo rapid transport to the hospital with ongoing CPR (ECMO candidates, pregnant, trauma, obvious reversible which can be treated in hospital only)
- •known esophageal pathology contraindicating TEE

结局指标
主要结局
Time to obtain images of the heart
时间窗: 10 minutes
Time from arrival of the study team on scene, until the following questions are answered by trans esophageal echocardiography: "is spontaneous cardiac movement present", "how ist LV function", "how is RV function", "is a pericardial effusion or tamponade present". The time will be measured in seconds and a maximum of 600 seconds is allowed. If answering the questions within 600 seconds is possible, the case will be counted as "feasible" and the duration of the time measured will be recorded. If answering the questions takes longer than 10 minutes, the case will be counted as "not feasible"
