Local Anesthesia Toxicity and Lipid Rescue
Local anesthesia systemic toxicity (LAST) is a rare but severe complication. Lipid emulsion therapy is an emerging treatment, and perianesthesia nurses play a key role in managing patients experiencing LAST.
Area of Science:
- Anesthesiology
- Emergency Medicine
- Nursing
Background:
- Regional anesthesia has been used for surgical pain control since the late 1880s.
- Local anesthesia systemic toxicity (LAST) is a rare, life-threatening complication of regional anesthesia.
- Lipid emulsion therapy has shown promise in treating LAST in animal and human studies.
Purpose of the Study:
- To review the role of perianesthesia nurses in managing LAST.
- To present evidence-based recommendations for LAST prevention, monitoring, and treatment.
- To discuss the pharmacologic characteristics of local anesthetics and sensory conduction.
Main Methods:
- A fictitious case study of a patient with LAST is used to illustrate concepts.
- Pharmacologic characteristics of local anesthetics are reviewed.
- Evidence-based practice recommendations are provided.
Main Results:
- Lipid emulsion therapy has demonstrated successful outcomes in human case reports for LAST.
- Perianesthesia nurses are crucial for patient assessment, communication, and emergent management of LAST.
- Understanding local anesthetic pharmacology is essential for prevention and treatment.
Conclusions:
- Lipid emulsion therapy is a vital treatment for local anesthesia systemic toxicity.
- Perianesthesia nurses require specific knowledge and skills to manage LAST effectively.
- Comprehensive strategies for prevention, monitoring, and treatment of LAST are essential.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
