Transesophageal Echocardiography During CPR in Patients With Out-of-Hospital Cardiac Arrest: The EXECT-CPR Randomized Clinical Trial

The authors aimed to determine whether transesophageal echocardiography (TEE) guidance during cardiopulmonary resuscitation (CPR) could improve outcomes in patients with nontraumatic out-of-hospital cardiac arrest compared to conventional CPR techniques. The study found no significant differences in the primary outcome of sustained return of spontaneous circulation or other secondary outcomes between the TEE-guided and conventional CPR groups, although the TEE group showed higher intra-CPR end-tidal carbon dioxide levels. These findings suggest that while TEE-guided CPR did not enhance clinical outcomes, it may offer hemodynamic benefits without increasing adverse events.
