59: Partial REBOA and US PreHospital ECPR Revisited

This month we discuss two different topics we've recently had on the podcast.  Albuquerque had started the first US prehospital ECPR program…. and now they have the first patient as well.  Jon and Darren will share with us the exciting news.  Second, we recently had Matt Martin on the podcast talking about partial REBOA.  We got tons of email about this.  This month Zaf Qasim and Austin Johnson come on to talk about some of the controversial aspects of partial REBOA.  Zaf also gives us a great update on the state of REBOA in the world.

 

58: First U.S. Pre-Hospital ECPR Program

The U.S. has seen pre-hospital programs spring up in Paris, UK, and Australia.  It was thought that due to billing issues this could never happen in America….but it has.  Jon Marinaro and Darren Braude have accomplished this against all odds.  Zack interviews the two of them on how they were able to accomplish this task amidst the many financial, logistic, and medical problems surrounding this monumental task.

56: Pressors, Fluid, or Flow – Optimizing ECMO Physiology

A post arrest patient just got initiated on ECMO.  Do you give fluids, add pressors, or increase flow?  Marc Dickstein, an anesthesiologist from Columbia University and an expert in the physiology of ECMO, talks with Zack about how to manage these patients, what diagnostics we need and how to optimize your use of the machine.  This talk is a must for everyone starting ECPR in their departments.

55 – Anticoagulation of the ECMO Patient with Troy Seelhammer

Do you give heparin to your ECMO patients?  Well, let's rethink this.  This episode is All Things Anticoagulation!  Zack talks with Troy Seelhammer, an intensivist from Mayo Clinic Rochester.  He manages ECMO patients in his daily practice there.  He has become a master of the subject of anticoagulation.  He will talk about heparin, bilvalirudin, or maybe no anticoagulation.  We talk about how TEG can affect our management.  We talk about PCC and Protamine when bleeding just won't stop.  He talks about the when to be aggressive and when to cut back.  Below is a wonderful synopsis of Troy's thoughts on anticoagulation on pump.

 

Goal Heparin levels are far from perfect but some suggestions

APTT 1.5 to 2.5 times normal

ACT level – 180-220 seconds

Antithrombin Levels – next generation

54: Confirmation of Wire Placement with Sacha Richardson

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.

53b: Resuscitationist Inserted Distal Perfusion Catheter with Chris Couch

 

In this episode, we again explore the world of the distal perfusion catheter.  You heard from Joe Dubose the vascular surgeons point of view; now let's see how non-surgeon resuscitationists are dealing with this problem.  You will hear from Chris Couch, a critical care trained emergency physician from Dallas Texas and his colleague Omar Hernandez who have some novel thoughts and experiences related to when and how we insert these catheters.  You will hear about checking compartment pressures, poor man's way to “fluoro” your catheter, and much more.

53: Distal Perfusion Catheter with Joe Dubose

Episode 53 is all about the distal perfusion catheter12.  We are inserting a 15-19 Fr catheter into the femoral artery.  This limits the flow of blood to the affected extremity.  Many institutions have gone to mandatory distal perfusion catheters.  This episode is all about those catheters – when, how, which, and where.  Joe Dubose, the world reknown vascular and trauma surgeon, joins us to discuss the details of this important piece of post pump initiation.

Take Homes –

  • Common Femoral -> Superficial Femoral Artery or Posterior Tibial/Dorsalis Pedis
  • Check distal perfusion frequently
  • 5-7 Fr Catheters
  • Doppler/Temperature/Color of distal extremity
  • Remember side port of arterial ECMO catheter significantly limits the flow dynamics through the catheter

52: Brain Freeze- Selective Retrograde Cerebral Perfusion for Intra-Arrest Neuroprotection

1,23456

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!

50b Inter-Facility Transport of ECMO patients Part 2 of 2

This is part 2 of Transport of ECMO patients.  Mikael Broman is one of the world's leaders on ECMO transport.  He works at the Karolinska institute in Sweden and ha

s and continues to publish in the arena of ECMO transport.  As you will see, he offers a world of experience and certainly some critical information that we would all benefit from listening to.  I'm a smarter ECMO-tologist as a result of Micke!1234

50a Inter-facility Transport of ECMO patients Part 1 of 2

This month we are looking at how to transport patients from one facility to another on ECMO.  This is a difficult task, full of potential catastrophes.  Zack interviews Leon Eydelman, an ER/Critical Care physician from Chicago, and Michael Broman out of Karolinska in Sweden.  Leon will be bringing us up to speed on what to do, potential fails, and how to start the process of setting up a transport process for ECMO patients.  Dr. Eydelman will be teaching a new section at Reanimate this January specifically geared toward the transport of patients.  So if you are a nurse, medic, perfusionist, or RT involved in the transport of ECMO patients you will not want to miss Leon's section  Sign up at Reanimateconference.com.  Part 2 of this podcast includes the interview with Dr. Broman which will blow your mind.  So much great stuff in both of these interviews.
