Connecting the dots: addressing lipid emulsion substitution risks in local anesthetic systemic toxicity

Key Points

• To evaluate the risks associated with lipid emulsion therapy in managing local anesthetic systemic toxicity.
• Discussion of existing guidelines by the American Society for Regional Anesthesia (ASRA) on local anesthetic toxicity.
• Analysis of the use of 20% intravenous lipid emulsion (ILE) as a rescue therapy.
• Review of literature on the benefits and risks of lipid emulsion substitution.
• Lipid emulsion is established as a preferred treatment for local anesthetic systemic toxicity.
• There are identified risks associated with the use of lipid emulsion therapy, necessitating careful management.
• Guidelines continue to evolve based on emerging evidence surrounding systemic toxicity.
