Feasibility of TEE During Cardiac Arrest in Dutch Emergency Departments

Status Not yet recruiting

Clinical Trial Summary

The goal of this feasibility study is to learn if Dutch ED providers are able to use transesophageal echocardiography during cardiac arrest. The main question it aims to answer is: • are the ED providers able to determine the area of maximal compression of the heart using TEE

Clinical Trial Description

Point-of-care ultrasound is a valuable diagnostic tool during cardiopulmonary resuscitation (CPR) in cardiac arrest and its use is recommended by international guidelines. Transthoracic echocardiography (TTE) is most commonly used, but has certain limitations. Image acquisition can be challenging due to patient specific factors such as body habitus. Also image quality may be impacted by the limited acquisition time during CPR pulse checks. Furthermore, observational data suggests that pulse checks are prolonged due to TTE, while minimizing interruption of chest compressions is emphasized for better CPR outcomes in the guidelines. Transesophageal ultrasound (TEE) is a possible alternative for TTE. It has the theoretical advantage of superior image quality and thereby possible reductions of chest compression delays. Furthermore, TEE gives the opportunity determine which part of the heart is compressed most effectively, which is referred to as the area of maximal compression (AMC). Animal studies showed that an AMC located over the left ventricle positively influenced hemodynamics and return of spontaneous circulation (ROSC) compared to an AMC over the aortic root. In human studies, data also suggests that AMC located on the left ventricle, as measured by TEE, may positively influence prognosis. In the Netherlands, TEE is currently not used in emergency departments during cardiac arrest. The purpose of this study is to investigate if point-of-care TEE can be used effectively and safely by providers and teams that have not previously used this modality. Given the paramount importance of quality of chest compressions, the ability of the providers to assess the location of the AMC will be the main focus of this feasibility study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
