ENCORE! #336: The Dangers of Local Anesthetics

ENCORE! #336: The Dangers of Local Anesthetics

Author: Maureen Osuna, MSN, RN - Nursing school educator, author, and nursing student enthusiast. January 8, 2026 Duration: 25:00
Every other week I'm republishing one of my most popular or impactful episodes. This week I'm highlighting Episode 336, which is all about local anesthetic systemic toxicity (LAST). You'll definitely want to give this one a listen. Local anesthetics are medications that block nerve impulses so that pain signals aren’t transmitted to the brain. The result is that the anesthetized area is numb and pain is controlled.  Just because local anesthetics are “local” doesn’t mean systemic toxicity can’t occur. LAST occurs when local anesthetics extend into the system at toxic levels. It most typically occurs due to the physician accidentally injecting the medication into the intravascular space. However, it can also be from locally administered overdose, which leads to systemic toxicity.  Hit play on this episode to dive into local anesthetic systemic toxicity so you can understand which of your patients are at highest risk and what to watch for! ___________________ Full Transcript - Read the article and view references.
