Overview
Brief Summary
In the U.S. alone, over 300,000 people per year have sudden out-of-hospital cardiac arrest (OHCA), and less than 1 out of 10 survive. The current standard practice for treating OHCA is to perform cardiopulmonary resuscitation (CPR) and Advanced Cardiovascular Life Support (ACLS) at the scene until either the heart is restarted or resuscitation efforts are considered hopeless and discontinued. An alternative strategy for those with refractory OHCA is expedited transport with ongoing mechanical CPR to an Emergency Department capable of performing extracorporeal cardiopulmonary resuscitation (ECPR). The purpose of study is to test if this strategy is feasible and beneficial.
Detailed Description
Out-of-hospital sudden cardiac arrest (OHCA) is a life-threatening condition in which the heart suddenly stops beating and there is no blood flow to the body. If cardiac arrest is not treated immediately, it causes sudden death. In the U.S. alone, over 300,000 people per year have OHCA, and less than 1 out of 10 survive. Therefore, it is important to study new ways of treating cardiac arrest patients in order to improve survival. The current standard practice for treating OHCA is to perform CPR and Advanced Cardiovascular Life Support (ACLS) at the scene until either the heart is restarted or resuscitation efforts are considered hopeless and discontinued. This practice is supported by the fact that all currently proven CPR therapies can be delivered by paramedics in the field. However, promising new strategies have emerged that are more feasible to initiate in the hospital. One such strategy is extracorporeal cardiopulmonary resuscitation (ECPR). ECPR requires placement of catheters in large blood vessels and connected to a machine to take over the work of the heart and lungs. This purpose of this study is to examine the feasibility and potential benefit of expedited transport with ongoing mechanical CPR for patients with refractory OHCA patients to an Emergency Department capable of initiating ECPR. FDA approved this study as a staged feasibility study to enroll 15 participants and submit data prior to enrolling the second 15 participants. After enrolling 15 participants, the PI chose not to pursue an amendment to enroll additional participants due to slow accrual and research restrictions related to COVID.

Outcomes
Primary Outcomes
ECPR Initiations Under 30 Minutes
Time Frame: Measured within 2 hours of cardiac arrest onset
Proportion of ECPR eligible patients with ECPR flow initiated less than or equal to 30 minutes from ED arrival
Emergency Department Arrivals Under 30 Minutes
Time Frame: Measured within one hour cardiac arrest onset
Proportion of patients with emergency department (ED) arrival less than or equal to 30 minutes from 911 call (or cardiac arrest onset if witnessed by EMS personnel).
