63: Covid and ECMO – Who do we cannulate? with Jenelle Badulak

“Normal life is changing.  It is now a covid 19 life” – Bin Cao

I write this with some trepidation as well as pride in the role we all get to play in Covid 19.  The sure in the US and many other places worldwide is just beginning.  It is on us to seek guidance from those who have gone through this already.  Today we will address the use of ECMO in Covid with an expert in ECMO who is in the throws of the worst outbreak of the United States – Seattle, Washington.  Jenelle Badulak and I give you a short yet powerful discussion about what Covid patients should receive ECMO.

Take homes for decision to initiate- comorbidities (HTN, DM especially), single organ dysfunction, young age, trajectory of course

Hosts – Jenelle Badulak, Zack Shinar

62: Jason Bartos Take 2: The Future of ECPR Now

Last month you heard Jason talk about the ECPR program at the University of Minnesota.  This month Zack and Jason talk about post initiation care and the crazy ECPR realities that Demetris, Jason and U of M have created.  The sky is the limit for their team!

61: Jason Bartos – ECPR Redefined

Jason Bartos and his crew at the University

Image result for university of minnesota cardiology"

of Minnesota have revolutionized the concept of ECPR for out of hospital cardiac arrests.  His crew are interventional cardiologists who take OHCA straight to the cardiac cath lab.  They have initiate times of around 6-8 minutes and have neurologically intact survival rates higher than 30%.  Below are two of Jason’s recent papers which every person who considers themselves an ECPR fan should pour over with a fine-toothed comb.  There is so much in these papers.  We split this interview into two pieces because there is so many pearls in it.

 

Outcomes

Resuscitation paper – 48% survival in 100 patients

Circulation paper 2020– 33% vs. 23% ALPS

  • Cohort who had VF/VT and one shock vs. a cohort who had VF/VT and failed to ROSC at the scene, in the ambulance, and then all the way to the hospital.
  • OHCA – > Straight to the Cath lab –> Get on ECMO –> Go to CCU under Cards care.
  • Inclusion criteria – Vf/vt, lactate <18, paO2 >50,ETCO2>10

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.

 

 

 

 

The Albuquerque Bean Dip!!  Love this organization from cleanse to cannulation

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
