#103 – Dexmedetomidine Deep Dive with Eliana Zimmerman

What’s up folks! This is Jon Lowrance with Anesthesia Guidebook and this is episode 103… a deep dive on dexmedetomidine with Eliana Zimmerman. This episode is coming out on January 21, 2024.

Before we get to the show I want to remind folks that I’ll be speaking in person at the Encore Symposiums’ Autumn in Bar Harbor & Acadia National Park conference running October 14-17 of this year. If you have never been to Maine, this is a great excuse to make it up here. And even if you have been or if you live here in vacationland… there’s scarcely a better place to be than Bar Harbor in October. It’s absolutely stunning. Peak leaf season usually hits in October for Bar Harbor, which is a coastal village just outside the entrance to Acadia National Park. Just google those key words… Acadia National Park – October. Or peak leaf season Bar Harbor. Then sign up for the conference ASAP because this one usually sells out quick. It’s Encore Symposiums’ Autumn in Bar Harbor & Acadia National Park conference, running October 14-17. I’m looking forward to bringing fresh perspectives on what’s new in anesthesia, pharmacology, ERAS, airway management & more for this conference. You’ll also get to meet a bunch of my friends & crew from Maine Medical Center, as this is one our team’s favorite conferences to attend… it’s close to home and has absolutely breath-taking scenery. I hope to see you there!

This is the second show I’ve done specific to dexmedetomidine… you’d have to go back a full 100 episodes… way back to episode #2 for the other show, which I did with Matt Poirier who I continue to work alongside at Maine Medical Center.

In this show, Eliana Zimmerman joins me to unpack the literature on perioperative use of dexmedetomidine, specifically focusing on the clinical impacts of dexmedetomidine in colorectal surgery.

As part of her doctorate research at Northeastern University, Eliana completed a series of expert panel inquires, synthesized with current literature, to arrive at recommendations for best practice concerning the use of dexmedetomidine in colorectal surgery. Her infographic and resources are provided in the show notes.

Eliana Zimmerman graduated Wesleyan University with a degree in Neuroscience in 2017, and University of Pennsylvania with a degree in Nursing in 2018. She worked as an ICU nurse at Jefferson Methodist Hospital from 2019 – 2022. She is currently a nurse anesthesia doctoral student at Northeastern University with an anticipated graduation of May 2025. In her limited free time she likes to backpack, run, and spend time outdoors. Her fiancé, two cats, and dog have kept her sane during the long days of anesthesia training.

#85 – The McLott Mix – Part 2 with Jason McLott, MSN, CRNA

Jason McLott, MSN, CRNA developed a mix of medications for doing opioid-free anesthesia that came to be know as the McLott Mix. It’s a combination of dexmedetomidine, lidocaine, ketamine and magnesium.

Jason is clear that the McLott Mix helps achieve opioid-free anesthesia, not opioid-free analgesia, recognizing the role of opiates, if needed, in post-operative analgesia plans.

Jason completed his anesthesia training at Oakland University’s Beaumont Nurse Anesthesia program and works in a CRNA-only practice at Blue Ridge Hospital in rural North Carolina. He regularly mentors SRNAs from Western Carolina University, giving them exposure to a CRNA-only practice, extensive regional anesthesia experience and opioid-free anesthesia techniques. Jason also instructs regional anesthesia courses with Twin Oaks Anesthesia.

If you’ve followed Anesthesia Guidebook for any amount of time, you’ll probably remember that Western Carolina University is my alma mater. I would highly recommend WCU as a premier school for becoming a CRNA. The faculty & clinical sites are top notch and you can’t beat the location down in Asheville, North Carolina.

In Part 1 of this conversation, we talked about Jason’s background, what led him to get into opioid-free anesthesia and the details of the McLott Mix and how he suggests it be used. In Part 2 of our conversation, we come back to talk in more detail on the nuances of how Jason uses the McLott Mix in his practice and how providers can instigate change in moving their practices and groups towards opioid-free anesthesia. Part 2 is a prime example of what Randy Moore & Desirée Chappell & I talked about in episode 82 on change management in healthcare. Hopefully these 2 shows with Jason McLott get you thinking about real ways that you can build opioid-free techniques into your anesthesia practice.

#2 – Dexmedetomidine – Matt Poirier, MSNA, CRNA

Matt Poirier, MSNA, CRNA joins Anesthesia Guidebook to give a run down on dexmedetomidine. We cover the pharmacology & dosing right off the bat in this episode and then we take some time to discuss the art of using dexmedetomidine peri-operatively.

Matt Poirier is a Certified Registered Nurse Anesthetist at Maine Medical Center, a level 1 trauma center in Portland, Maine.  He obtained his Bachelor of Science in nursing from the University of Southern Maine and his Master of Science in nurse anesthesia from the University of New England.  Prior to Matt’s nursing career, he attended Assumption College in Worcester Massachusetts and obtained a Bachelor of Arts in biology and chemistry and subsequently worked as both an analytic and synthetic chemist.
