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

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 42: Organ Transplantation On ECMO

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!!

EDECMO Episode 41 is REPOSTED

The original post for EDECMO 41 had to be permanently removed from the internet (for reasons beyond our control!!!) but its back. Click this link to take you to the new and improved (and HIPAA-compliant!!) episode: EDECMO 41 – The 3 stages of ECMO – Diane's Story

EDECMO 40: EROCA – The trial that asks “Should ER Docs Initiate ECPR?”

 

EROCA – University of Michigan – Gunnerson/Shinar

Should Emergency Physicians initiate ECMO on arresting patients?  That is the question that Kyle Gunnerson from the University of Michigan (UMich) is asking with their new trial – EROCA.  UMich has had a robust ECMO program for over 30 years and recently they have received a grant to fund an out of hospital cardiac arrest protocol for emergency physician initiated ECPR.  In this episode, Zack asks Kyle how this trial is being undertaken with key side points on how to start a program, how to train the personnel, and how to circumnavigate the many roadblocks we commonly face in the development of an ECMO program.  They talk about the limitations of running a trial with physicians with no prior experience in ECPR initiation as well as the novel resuscitation strategies that UMich is deploying in all of their cardiac arrest patients.

 

2016 ECMO CPT Codes, RVUs, and MediCare Reimbursement

Ok, so we just crashed an arrested patient onto ECMO and he is going to the cath lab. Now, how do I document the procedure again?  What was the CPT for percutanous cannulation for VA-ECMO?  Does my billing company even know?

Bookmark this page for future quick reference of the current CPT codes, RVU values and MediCare reimbursements.

EDECMO 39: Who Do We Put On ECMO? – New Data on Prognostics

In this episode Zack interviews the first authors of the three biggest papers this year dealing with the question of “Who should I put on ECMO?”  Guillaume Debaty of Grenoble, France published a paper outlining what prognostic factors are important.  Guillaume's data shows importance of short low times, lower lactates and higher pH values.  The real question is what number for each of these should we consider a hard stop on initiation.  This is followed up by Josh Reynolds who along with Ben Singer out of the UK published a paper utilizing cardiac arrest data from the PRIMED trial.  He showed that even patients with all the advantageous characteristics of traditional ECMO inclusion criteria had poor survivals once they have had >30 minutes of chest compressions.  With many ECMO studies having average arrest to

initiation times of > 60 minutes, Josh’s paper certainly makes us view favorably the 30% survival outcomes that we are seeing worldwide.  This in no way substitutes for a randomized trial but does offer some guidance on what the expected survival of a patient with a witnessed arrest, short low flow times, and age < 65.   We  conclude with Nate Haas out of the University of Michigan who utilitzed the ELSO database to show that age was not predictive of survival.  This may push us towards including older patients in our inclusion criteria, but more data is definitely needed on this.

Crash Episode: Iowa OHCA ECMO Save – with Andrew Karl Terry

Crash Episode – This is a great example of where a little persistence with your colleagues can help save someone's life.  Dr. Andrew Karl Terry, having had only limited exposure to ECMO, was able to encourage his Cardiologists to put a witnessed VF patient on ECMO.  The rest is history!
