Episode 11 - ECMO Implementation for Refractory Cardiac Arrest in the ED

Following the success of Episode 6, which discussed the scientific evidence for ECMO in cardiac arrest, we decided to take a deeper look at the implementation of ECMO in the ED. Drs. Felipe Teran and Joseph Tonna discuss the utilization of ECMO for refractory cardiac arrest, the expansion of hospital ECMO programs to the emergency department and implementation of an ECMO program for cardiac arrest. This episode was recorded on location in Salt Lake City, Utah.

Episode 10 - TTM Following Opioid Overdose Cardiac Arrest

Drs. Teran and Abella discuss the role of TTM for patients following cardiac arrest caused by opioid overdose. Several recent observational studies are reviewed to understand the demographics of patients who suffer opioid-related cardiac arrest, their outcomes, and whether TTM may be beneficial during post-arrest for these patients.

Episode 9 - MRI Imaging for Post-Arrest Neurological Prognostication

Following resuscitation from cardiac arrest, accurate evaluation of neurological recovery can help guide patient care and family decisions. In this podcast, Drs. Teran and Abella discuss a recent investigation into the use of MRI imaging in prognostication following resuscitation from arrest.

Episode 8 – Oxygen Delivery After Cardiac Arrest Resuscitation

Episode 8 – Oxygen Delivery After Cardiac Arrest Resuscitation

 

During cardiac arrest resuscitation, most patients are intubated and placed on 100% oxygen. In this podcast, Drs. Teran and Abella discuss recent investigations that suggest that too much oxygen may worsen post-arrest injury. Global resuscitation guidelines suggest down-titration of oxygen as tolerated to maintain adequate O2 saturation, but it’s not clear how well this is done- many patients are left on high oxygen “dose” for hours.

Episode 7 - Cardiac Arrest Regionalized Care

Drs. Felipe Teran and Ben Abella discuss an important recent publication in Annals of Emergency Medicine by Elmer et al, in which some of the strongest evidence to date are presented that support the concept of “cardiac arrest centers”, much like trauma or stroke centers. This has been proposed before (Nichol G et al, Circulation 2010 – see below) – but evidence is now accumulating in support of the idea.

Episode 6 - ECMO for Cardiac Arrest

Drs. Benjamin Abella, John Greenwood and Felipe Teran discuss the use of ECMO (extra corporeal membrane oxygenation) for cardaic arrest patients.
