Intravenous lipid emulsions have been introduced for the management of patients with Local Anesthetic Systemic Toxicity (LAST). These emulsions have been stated as a first-line treatment in the guidelines of several international anesthesia organizations. Nevertheless, the adoption of lipid rescue therapy by Chinese practitioners remains unknown. We, therefore, evaluated the current approaches to treat LAST and the use of lipid rescue therapy among anesthesiologists in China. ⋯ Lipid emulsion is not widely available in China to treat LAST resulted from RA for orthopedic patients. Efforts are required to promote lipid rescue therapy nationwide.
