University Hospital of North Norway:

  • located at 69 degrees North latitude – likely the northernmost ECMO center in the world.
  • The warmest month is July with a mean air temperature of 11.8C and mean sea temperature of 10.8 C.
  • The coldest month is January with a mean air temperature of -4.4 C and mean sea temperature of 5.1 C.
  • ECMO program since 1988
  • Yearly ECMO volume is approx 20 per year – including postcardiotomy support, ECPR, cardiogenic shock and respiratory failure
  • ECMO Retrieval Ambulance service: Since 12/2015: 5 ECMO transports
  • Cases are reported through the ELSO registry

Accidental Hypothermia – some definitions:
mild : 32-35 C – preserved capability to maintain core temperature through compensating thermoregulatory mechanisms
Moderate: 28-32 – loss of ability to sustain temperature via either voluntary or autonomic means
Severe: 20-28 – high risk of malignant arrhythmias
Profound: <20 Asystole

The Paper: Hilmo, J et al. Prolonged resuscitation is warranted in arrested hypothermic victims also in remote areas – A retrospective study from northern Norway. Resuscitation , Volume 85 , Issue 9 , 1204 – 1211

  • “Nobody is dead until warm and dead”
  • retrospective study looking at accidental hypothermia victims with cardiac arrest admitted to UNN between 1985-2013
  • no survivors prior to 1999
  • 1999-2013: 9/24 (37.5%) survival, defined as alive at 1 year – most with a ‘favorable’ neurologic outcome
  • PRIOR studies suggested that asphyxiation, either via snow burial (avalance) or water submersion had a lower chance of survival, but this study suggests that hypothermic arrest during submersion injury may be very different. It is hypothesized that very cold temps create faster cooling rates and aspiration of cold water may induce rapid protective cerebral hypothermia. So drowning victims (asphyxia by submersion in cold water may have a higher survival)
  • Hyperkalemia is bad (>8 is bad; >12 is dead)
  • Bottom Line: “No patient is dead until they are warm and dead” – current neuroprognostication can’t identify OHCA patients who may be salvageable.  So assume they are!

Key ECMO Points:

  1. Profoundly hypothermic patients cannot generate high flow rates – possibly due to increase blood viscosity.  Consider larger cannulae. Torvinde uses 29F venous and 21F arterial as a starting point.
  2. Rewarm with a veno-arterial temperature gradient of no more than 10 degrees C. Faster rewarming may result in bubble formation. Torvinde does this via the water bath heater/cooler.
  3. Therapeutic hypothermia is still in play. Torvinde holds the core temp at 36 for 24-28 hours.
  4. “You’re not dead unless you’re warm and dead” – consider transporting potentially salvageable patients with a reliable history.

Building REANIMATE 1: a video montage

While preparing for #REANIMATE16 there were no simulators for ECPR. There were no commercially available models for ECPR cannulation. There was nothing.

We had to build it. From scratch.

This short video documents the building of #REANIMATE16: the first international endovascular resuscitation conference.

*special thanks to Jeremy Haywood for producing this video: jeremyhaywoodphotography.com

 

Thinking back on #REANIMATE16, I couldn’t help but think of the iconic American movie ‘It’s a Wonderful Life’, featuring Jimmy Stewart. Although the audio soundbytes in this video may seem out of context, I hope the concept of ‘building’ something from nothing was preserved:

It’s a Wonderful Life is a 1946 American Christmas fantasy drama film produced and directed by Frank Capra, based on the short story “The Greatest Gift”, which Philip Van Doren Stern wrote in 1939 and published privately in 1945. The film is now among the most popular in American cinema and because of numerous television showings in the 1980s has become traditional viewing during the Christmas season.

The film stars James Stewart as George Bailey, a man who has given up his dreams in order to help others, and whose imminent suicide on Christmas Eve brings about the intervention of his guardian angel, Clarence Odbody (Henry Travers). Clarence shows George all the lives he has touched and how different life in his community of Bedford Falls would be had he never been born.

Despite initially performing poorly financially because of high production costs and stiff competition at the time of its release, the film has come to be regarded as a classic. Theatrically, the film’s break-even point was $6.3 million, approximately twice the production cost, a figure it never came close to achieving in its initial release. An appraisal in 2006 reported: “Although it was not the complete box office failure that today everyone believes … it was initially a major disappointment and confirmed, at least to the studios, that Capra was no longer capable of turning out the populist features that made his films the must-see, money-making events they once were.”[7]

It’s a Wonderful Life is one of the most acclaimed films ever made, praised particularly for its writing. It was nominated for five Academy Awards including Best Picture and has been recognized by the American Film Institute as one of the 100 best American films ever made,placing number 11 on its initial 1998 greatest movie list, and number one on AFI’s list of the most inspirational American films of all time. Capra revealed that the film was his personal favorite among those he directed, adding that he screened it for his family every Christmas season.

REANIMATE 2: September 12 & 13, 2016

REANIMATE 1 is now behind us. And it was a “yoooooooge” success (Reanimators from R1 will get that one!) On February 25 and 26, 2016 physicians, nurses and paramedics from around the globe met at the UCSD Simulation Center/Center for the Future of Surgery and immersed ourselves in the art and science of Endovascular Resuscitation: ECMO, ECPR, REBOA, bleeding-edge resuscitation, and more.    From  the entertaining (and for Bellezzo maybe a little humiliating!) didactic sessions to hands-on down-and-dirty sim sessions, participants were given the opportunity to train with the best educators in the world of resuscitative science. And now we are ready to make it even better!

REANIMATE 1 sold out one week after opening registration. Those who couldn’t get into REANIMATE 1 made it onto a  waiting list for R2, which  is selling out fast. Register NOW and don’t miss out!

Check out the video:

EDECMO 25.5 – (Part 2) an EDECMO short with Jim Manning – on location with the SAMU pre-hospital ECMO team in France

In followup to our discussion with Jim Manning MD (@JManning_UNC)  and Lionel Lamhaut (@LionelLamhaut) MD of the Service d’Aide Médicale Urgente (SAMU) for EDECMO Episode 25, the guys spent the last few days ‘just hanging out in Paris.”

The recent massacre in Paris certainly makes this topic..well…topical.

Manning spent several days with the prehospital ECMO team in France.  In this episode Zack interviewed Manning, who was on-location with the SAMU in France…and walks us through the experience of witnessing prehospital ECMO with the SAMU.

In the U.S., we aren’t yet ready for pre-hospital endovascular resuscitation – indeed there are currently several barriers to overcome. But perhaps the Europeans are onto something here:

Femoral cutdown vs. percutaneous access? Discussed. Verdict?

Transporting a patient on ECMO:

You know, the thing is…that once you have a patient on ECMO, everything chills out…

-Jim Manning

Every patient gets:

  • Dobutamine: 5 ug/kg/min
  • Norepinephrine 3 mg/hr
  • pRBC 2 units
  • FFP 2 units

Flow goals: start 2.5-3 lpm…then slowly increase. Does this help quell reperfusion injury?

This is the exciting. This is fantastic. This is the future if you ask me. We are going to be doing this and its just a matter of time before the rest of us realize that…we are headed in the right direction
