In this episode, Sacha Richardson talks with Zack about a problem common to all ECPR programs- how do we confirm the placement of the wires?  During chest compressions and even in patients with a pulse, confirmation of which vessel you have cannulated can be difficult.  Sacha shares some tricks and trips on how to get real time confirmation of the wires.  Sacha also gives us a preview of some of the exciting endeavors that he has undertaken in Melbourne with pre-hospital ECMO.

We've all heard of therapeutic hypothermia.  Some of us have heard of deep hypothermia for traumatic arrest.  But what about deep regional hypothermia of brain for cardiac arrest!  Zack interviewed Rob Schultz, a CT surgeon resident from Calgary who is doing research on deep hypothermia of the brain using some of the tactics that are utilized in operating room.  His stuff is mind blowing!

NEW PAPER: Extracorporeal Life Support in the Emergency Department: A Narrative Review for the Emergency Physician

Posted on December 5, 2018 // Leave a Comment

Pulmonary Critical Care guru Justyna Swol from Nuremberg, Germany invited Scott, Zack and me to co-author this paper along with several other ECLS experts.   Just published in the Journal Resuscitation, this is a great overview of Emergent ECLS(AKA ECPR) from the point of view of the Emergency and Critical Care specialist.1

49 – You Can’t Spell REBOA without the ER – Endovascular Resuscitation of the Trauma Patient – Zaf Qasim

In this episode, Zack Shinar interviews Zaf Qasim about the recent controversies with ACEP and ACS about who can do REBOA.  Zaf is one of the world's experts on REBOA and he's an ER doc!  Zaf works at the University of Pennsylvania, trained in London

as well as Shock Trauma in Baltimore and teaches at Reanimate.  When you come to the essence of this episode, the question is what is the emergency physician's role in the trauma resuscitation?  Both Zaf and Zack agree; we need to be the resuscitationist in the trauma suite.  We need to manage the airway and then quickly take over the arterial and venous access, interpret the transduced pressures, manage the massive transfusion protocol and be ready to insert the REBOA catheter while the trauma surgeon is involved with the left chest, the source of bleeding and where the next destination for this patient will be.

This part two of August 2018.  We are now tackling the difficult question of when to transport cardiac arrests if I have ECMO available?  Brian Grunau is an expert in this question.  Brian has become a giant in the world of ECMO.  His research, leadership and experience have pushed the Canadian ECPR contingency to the forefront.   Brian gives us some insight on what factors I should consider and when should I transport.1

Over this last year we have had episodes on organ donation and decision to transport.  This month we are revisiting two topics with two amazing people in two separate episodes.  Here, I interviewed Velia Marta Antonini.   Velia works in Italy where several of the great ECMO donation papers have originated.  She explains why this research is coming from Italy, what the process looks like, and the implications of this for other countries.  Check out her slides below.

Well, it only took us seven years to figure this one out.  The wire assistant has been the key advancement of 2018 for placement of ECMO cannulas.  In this episode, Zack and Joe talk through this process after an  interview with Alyssa Baldini.  Alyssa was one of our first true wire assistants and has been instrumental in getting cannulas in faster and safer.  We discuss how the wire assistant aids in sterility and getting the artery on the first stick.  Bottom line – train someone at your shop to be an expert wire assistant.

EDECMO 45: ECMO in Sepsis

In this episode, Zack talks with Heidi Dalton about ECMO use in Sepsis.  This is another controversial area with pediatric literature showing strong results while the adult results have been less impressive.  Heidi has been a key figure in both adult and pediatric ECMO.  She is the former chair of the yearly ELSO conference.  She is a professor at both George Washington University and Virginia Commonwealth University.  Her background is in pediatric critical care. She currently works at INOVA in Virginia where she is the director of adult and pediatric ECMO.

Sepsis has been thought to be a contraindication to ECMO use secondary to the pro-inflammatory nature of ECMO and potential to harbor infection.  Recent research is certainly controversial with adult studies showing low survival in septic shock and sepsis as a cause of arrest.  As with much of ECMO literature, the problem is with the denominator – What is the expected survival of these patients?  The follow up question becomes what effort is prudent for these low survival rates?  The sepsis cohort tend to be younger and potential for long term survival is high.  The question remains should we be utilizing ECMO for sepsis?1–9

In this episode, Zack Shinar interviews Dr. Bob Bartlett from the University of Michigan.  Dr. Bartlett has revolutionized the world with his leadership and innovation from the very beginnings of ECMO.  Zack and Bob discuss the history of ECMO and the prior use of roller pumps and bubble oxygenators.  They go on to describe the advantages of centrifugal pumps and hollow fiber oxygenators.  Additionally, they talk about PMP (polymethylpentene)-coated membranes inside oxygenators and their improved ability to safely oxygenate blood.  They discuss anticoagulation and how Bob believes that direct thrombin inhibitors are superior.  They wrap it up with a discussion on the future of ECMO and how peristaltic pumps have some significant advantages2.

In this episode, we tackle the subject of organ transplantation on ECMO.  2017 featured several articles showing the efficacy of ECMO for organ transplantation.  In Italy, 56% of total potential patients were successfully transplanted.  The success of these transplants have been comparable to patients not on ECMO.  Zack Shinar interviews Lionel Lamhaut, ECMO specialist from Paris, and Cyrus Olsen, ethicist from the University of Scranton, to dive into some of the deeper questions including financial implications, ethical angles, and research extrapolations.  Join Zack, Lionel and Cy at Big Sick 18 (bigsick18.org) in Zermatt Switzerland on February 7-9th,, 2018!!
