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

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.

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

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

EDECMO 46: Wire Assistant

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 44: Bob Bartlett: Peristaltic Pumps, Hollow Fibers, and the History of ECMO

1

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.

EDECMO 43: The Cutdown

The Cutdown Approach to ECMO Cannula Insertion with Alice Hutin, Lionel Lamhaut, and Zack Shinar

In this episode,  Alice Hutin of the Paris SAMU talks about the modified cutdown approach to cannula insertion.  She is an emergency physician who is one of four physicians who cannulates on the pre-hospital ECMO ambulance.  She describes the process of their modified cutdown.  We are holding off on written descriptions and pictures of the procedure pending Alice's publication so you will just have to listen!!!! We'll post the pictures soon!  Until then, here is a youtube segment showing a femoral cutdown -https://www.youtube.com/watch?v=zzu7cU3YoXo

EDECMO 41 – The 3 Stages of ECPR – Diane’s Story

[The original EDECMO 41 post had to be taken down…for reasons beyond our control! But here is the new and improved Episode 41]

In this episode Zack and Joe discuss the 3-stages of Extracorporeal Membrane Oxygenation (ECMO) – or put another way, this is how to start Extracorporeal Cardiopulmonary Resuscitation (ECPR) in the Emergency Department (ED). It's been 4 years since we talked about these basic premises of ECPR. But this time, its highlighted in a very special story.

The Three Stages of ECPR:

  1. Placement of any commercially available catheters into the femoral artery and femoral vein.
    • Ultrasound-guided percutaneous access is our preference, but cutdown is also considered.  This is done in every patient, every time, and is done in parallel to ongoing ACLS. Transduce the arterial line to guide resuscitation and use the venous line for resuscitation purposes.
  2. Transition to ECMO cannulas
    • Using guidewires (we prefer the Amplatz Super Stiff 145 cm .038″ teflon coated floppy tip wires), remove the catheters placed in Stage 1, perform serial dilation, and place ECMO cannulas
  3. Initiate the ECMO pump
    • Perform ‘underwater seal' using crystalloid, which closes the circuit.  The circuit is de-aired and the pump is started.  Increase the RPM to 1500 and remove the clamps.  Inspect the circuit and troubleshoot any issues.

3 stages. 3 steps.

You can find a whole lot more on our ECPR 3 stages page.

Diane's Story:

November 30, 2017: Diane suffered ventricular fibrillation (VF) cardiac arrest and collapsed…just outside the ED doors.  CPR was started immediately by an ED nurse. After 32 minutes of failed Advanced Cardiac Life Support (ACLS), with human and mechanical chest compressions, she remained in refractory VF.

Our Emergency Physician-initiated ECMO (ED-ECMO) protocol was initiated using the ‘3 stages of ECMO.'   Diane was ‘on pump' in 32 minutes, taken to the cath lab, and had her 95% LAD lesion stented by Interventional Cardiologist Arvin Narula.

Diane went home with her family and friends on December 13, 2017.  Listen to the episode to hear the details…
