#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.
