Using Transesophageal Echocardiography for Cardiac Arrest Patients

Transesophageal Echocardiography in Pre-hospital Cardiac Arrest Patients; TAPCAP

Not applicable Interventional Far Eastern Memorial Hospital · NCT06672315

This study is testing if a special ultrasound called Transesophageal Echocardiography can help doctors find out why some people have a cardiac arrest outside the hospital, to improve their chances of recovery.

What this trial studies

This study evaluates the use of Transesophageal Echocardiography (TEE) in patients experiencing out-of-hospital cardiac arrest (OHCA). It aims to determine the effectiveness of TEE in providing clear diagnostic images that can assist in identifying reversible causes of cardiac arrest, such as pericardial tamponade and pneumothorax. The study leverages the training of emergency medical technicians in Taiwan, who are equipped to perform ultrasound examinations in the pre-hospital setting. By comparing TEE with other imaging techniques, the study seeks to improve patient outcomes in emergency situations.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have experienced an out-of-hospital cardiac arrest from a non-traumatic cause.

Not a fit: Patients who have obvious signs of death or have expressed a Do Not Attempt Resuscitation (DNR) order will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance the management of cardiac arrest patients by providing timely and accurate diagnostic information.

How similar studies have performed: Previous studies have shown the feasibility and effectiveness of TEE in pre-hospital emergencies, indicating a promising approach for this patient population.
