Now LAs are used many procedures in many clinics, especially in emergency departments (EDs). The extensive use of LAs was brought side effects and toxicity. Local anesthetic systemic toxicity (LAST) have been reported from simple allergic conditions to cardiovascular and neurological complications that can be fatal. The study aims to evaluate the level of knowledge and awareness of LAST among emergency medicine residents (EMRs). Methods: This was a questionnaire-based cross-sectional study. The questionnaires were sent to EMRs via e-mail, and responses were collected. The participants who gave informed consent included in the study, and who didn't use LAs in their daily practice were excluded. All of the participants responded all of the questions and responses were analyzed. Results: 92 EMRs were included in the study. The median age of the participants was 29 (24-50) years, and 48.9% were women. In the research, no one could recognize all LAST symptoms, ranging from mild to severe. Only 16.3% of the participants answered all treatment options of the LAST correctly, and 27.2% knew the intravenous lipid emulsion dosage accurately. Conclusions: The level of knowledge and awareness of the EMRs on LAST were insufficient. EMRs training rates on LAs and LAST were found to be low. In addition, it was stated that the patient's informed consent was not appropriately obtained from the vast majority of patients undergoing LA procedure. As the first study on LAST among EMRs, we believe that necessary arrangements should be made regarding the detected deficiencies.en10.18521/ktd.746744info:eu-repo/semantics/openAccessLocal AnestheticsLocal Anesthetic Systemic ToxicityEmergency Medicine ResidentsIntravenous Lipid EmulsionLipid TreatmentArticle123414419WOS:000613115500004N/A
