In this episode, we’re diving into the world of inhalant anesthetics—specifically isoflurane and sevoflurane—and how they fit into a balanced anesthesia protocol. Join Tasha & VTS (Anesthesia & Analgesia) Jen Dupre-Welsh as they break down the pharmacology, pros and cons, and clinical considerations of each agent. Whether you're a seasoned technician or just getting comfortable with gas anesthesia, this episode will help you better understand how these inhalants contribute to safe and effective anesthetic plans in veterinary practice.

Nutrition is often a forgotten aspect of the overall animal healthcare experience, especially when compared to the more "sexy" specialties such as ECC and Anesthesia. However, nutrition plays a VITAL role in effecting almost all specialties and body systems of our patients. Today we talk to Robin Saar, a VTS (Nutrition) to talk about how nutrition plays a role specifically in post op recovery, and pain managment!

About Robin: Robin is a vintage registered veterinary technologist with a Veterinary Technician Specialty in Nutrition. Her professional experience includes working in small and mixed animal practices as an RVT, and a Practice Manager, developing a nationwide nutrition program for a Canadian veterinary corporation, and gaining sales and customer education skills at a start-up microbiome-focused company. Currently, at Royal Canin, Robin is a Sr. Scientific Communications Technician and she is completing her masters in Animal Nutrition at the University of Glasgow. Robin is a peer-reviewed, published author and was the lead author on the first dedicated textbook “Small Animal Microbiomes and Nutrition”. She enjoys supporting the veterinary community and volunteers on multiple organization boards.

Sure you have used the vent, but are you always using PEEP? Should we always be using PEEP? This episode features Erin Czerwonka who is not only and RVT but also and RRT (Registered Respiratory Therapist!!!

While her primary focus has always been referral anesthesia, Erin has also gained valuable experience working in the Ophthalmology, Cardiology, and ICU departments. In 2015, she took a significant detour from veterinary medicine to pursue an Advanced Diploma in Respiratory Therapy. In January 2018, she successfully challenged the Canadian board examination to become a Registered Respiratory Therapist (RRT). Although she no longer maintains her RRT status, the knowledge and skills she acquired during that time continue to enrich her anesthesia practice every day.

A lifelong nerd at heart, Erin has always had a passion for learning. Her current professional interests include locoregional anesthesia, difficult airway management, mechanical ventilation, and pain management. She is currently pursuing certification as a Certified Veterinary Pain Practitioner (CVPP) through the International Veterinary Academy of Pain Management (IVAPM).

Outside of work, Erin enjoys kayaking and watching tennis with her husband, Mason. She also delights in showering affection—sometimes aggressively—on her dog, Auzi, and her two cats, Bruce Wayne and Hazel.

With all the buzz around climate change, you may not have stopped to think how our work in anesthesia contributes to the overall warming of the planet. But, Toby Trimble is here to break it down for us. In this episode we discuss some of the ways the anesthesia industry contributes to environmental issues. Volatile anesthetics are potent greenhouse gases, meaning they trap heat in the atmosphere and contribute to global warming. Lets discuss ways we can keep our patients (and the earth) as safe as possible.

Toby is the founder of Trimble Group, a veterinary led creative consultancy company reinventing education for animal health, making it less like PowerPoint and more like Netflix. He focuses on making education engaging, visual, and memorable. With his team, Toby has created over one thousand CPD videos and live broadcasts in the UK, Europe, Asia and Australia.

Listen in to this episode of the Veterinary Anesthesia Nerds podcast for a crucial discussion with Dr. Gianluca Bini on the evolving landscape of perioperative pain management. This episode dives into the potential overuse of opioids in veterinary medicine and explores the exciting possibilities of incorporating Enhanced Recovery After Surgery (ERAS) protocols. Dr. Bini highlights the strategic use of local and regional anesthetic blocks as a key component of ERAS, demonstrating how these techniques can significantly reduce opioid reliance, improve patient outcomes, and pave the way for a more balanced approach to veterinary anesthesia.

Ever wondered about the difference between oxygenation and ventilation? 🫁💨 Join us as Veterinary Technician Specialist Meagan Crowley breaks it down in a way that’s both practical and engaging! Useful for every anesthesia case you perform, we’ll explore why understanding this distinction is critical for patient care. Hypoxemia, hypoventilation, physical monitoring parameters, and physiology will be discussed. Whether you’re a vet tech, vet, or student, this episode is packed with insights you won’t want to miss!

We are all taught in school that if a patient become hypotensive, they should receive a fluid bolus. But, does that make sense for all patients? When do you reach for an anticholinergic? When do you start that dopamine or norepi?

Amanda Shelby RVT, VTS (Anesthesia & Analgesia) is here to explain it all to us.
