ECPR for Refractory Out-Of-Hospital Cardiac Arrest
ECPR for Refractory Out-Of-Hospital Cardiac Arrest
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.
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.
