In this episode of The Poison Lab, host Ryan Feldman is joined by Dr. Joe Kennedy, medical toxicologist at the University of Vermont and consultant for the Northern New England Poison Center. Together they work through real poisoning cases to sharpen toxic differentials, sum up practical resuscitation priorities, and connect first-principles pharmacology to bedside decisions. They also answer listener questions on THAM vs bicarbonate, when to dialyze even with “normal” kidneys, and why rattlesnake antivenom costs so much—plus the real-world logistics of sourcing exotic antivenoms in the U.S.

Dr. Kennedy and Ryan discuss the topics below. Looking for timestamps? Join the subscribed feed!
