#49 – Local Anesthetics with Skyler Rouhselang, BSN, SRNA

This episode was originally published in April 2019 on From the Head of the Bed… a podcast for the anesthesia community. In this podcast, Skyler provides a thorough overview of local anesthetics including relevant anatomy and physiology (i.e. nerve fibers, sodium channels, pKa, etc), types of local anesthetics and factors that effect onset, potency, duration of action and absorption. We touch on methemoglobinemia, Local Anesthetic Systemic Toxicity (LAST) and common dosing and max dosing for local anesthetics. This is a great run down for anyone wanting to brush up on local anesthetics! At the time of this recording, Skyler Rouhselang was a second-year SRNA at Marian University in Indianapolis, IN. She attended Ball State University for her undergraduate education where she earned her BSN in 2013. Skyler went on to work in the medical ICU at a level 1 trauma center in downtown Indianapolis for 5 years before returning to school to complete her Doctor of Nursing Practice degree. Skyler has married and changed her name to Skyler Williams, DNP, CRNA. As of September 2021, Dr Williams practices anesthesia as a CRNA at IU Health Arnett Hospital in Lafayette, IN.
