| Abstract (English): | Local anesthetics are used daily in diagnostic and therapeutic procedures; therefore, their unsafe use must be prevented through medical education to avoid adverse effects resulting from their application. Objectives: To describe the knowledge and practices related to the safe use of local anesthetics among final-year medical students in Medellín. Materials and methods: A descriptive, cross-sectional, observational study was conducted using non-probability sampling. Two hundred adult medical students in their final year of undergraduate studies enrolled at universities in Medellín were surveyed. Students who indicated they had not taken an anesthesiology course or who did not provide informed consent were excluded. Sociodemographic variables, variables related to the education received regarding the safe use of local anesthetics, and the frequency of applying preventive practices when administering them were evaluated. Results: 88% of respondents reported having received education related to the safe use of local anesthetics. Lidocaine was the most frequently used anesthetic among respondents (94.5%). A majority of students were unaware of the maximum safe dose of lidocaine. 51% of respondents almost never or never calculated the maximum safe dose before administering a local anesthetic, 45% almost never or never monitored vital signs, and 27% almost never or never administered the anesthetic in the presence of an instructor. 75% of respondents did not feel prepared to manage local anesthetic toxicity. Conclusion: The surveyed students perceived that they did not have optimal training in the safe use of local anesthetics and did not apply preventive strategies to reduce risks when administering these drugs.

| Abstract (Spanish): | Los anestésicos locales son utilizados diariamente en procesos diagnósticos y terapéuticos, por lo que su uso inseguro debe prevenirse desde la educación médica, con el fin de evitar efectos adversos derivados de su aplicación. Objetivos: describir los conocimientos y prácticas relacionadas con el uso seguro de anestésicos locales que poseen los estudiantes de medicina de último año en Medellín. Materiales y métodos: estudio observacional, descriptivo y transversal en el que se aplicó un muestreo no probabilístico, encuestando a 200 estudiantes mayores de edad, que se encontraban en el último año del pregrado de medicina y que estuvieran matriculados en universidades de Medellín. Se excluyeron estudiantes que indicaron no haber cursado la asignatura de anestesiología y que no brindaron su consentimiento informado. Se evaluaron variables sociodemográficas, variables relacionadas con la educación recibida frente al uso seguro de anestésicos locales y la frecuencia de aplicación de prácticas preventivas al administrarlos. Resultados: el 88% de los encuestados aseguraron haber recibido educación relacionada con el uso seguro de anestésicos locales. La lidocaína fue el anestésico más utilizado por los encuestados, con un 94.5%. Predominaron los estudiantes que desconocían la dosis máxima segura de la lidocaína. El 51% de los encuestados casi nunca o nunca calculaban la dosis máxima segura antes de administrar un anestésico local; el 45% casi nunca o nunca realizaba monitorización de signos vitales y el 27% casi nunca o nunca realizaba la administración en compañía de un docente. El 75% de los encuestados no se sentían preparados para manejar una intoxicación por anestésicos locales. Conclusión: Los estudiantes encuestados percibían que no contaban con una formación óptima en el uso seguro de anestésicos locales y no aplicaban estrategias preventivas que disminuyeran los riesgos al administrar estos fármacos.

| Abstract (Portuguese): | Anestésicos locais são utilizados diariamente em procedimentos diagnósticos e terapêuticos; portanto, seu uso inseguro deve ser prevenido por meio da educação médica para evitar efeitos adversos decorrentes de sua aplicação. Objetivos: Descrever o conhecimento e as práticas relacionadas ao uso seguro de anestésicos locais entre estudantes de medicina do último ano em Medellín. Materiais e métodos: Foi realizado um estudo observacional, transversal e descritivo, utilizando amostragem não probabilística. Duzentos estudantes de medicina adultos, cursando o último ano da graduação em universidades de Medellín, foram entrevistados. Foram excluídos os estudantes que indicaram não ter cursado anestesiologia ou que não forneceram o consentimento livre e esclarecido. Foram avaliadas variáveis sociodemográficas, variáveis relacionadas à educação recebida sobre o uso seguro de anestésicos locais e a frequência de aplicação de práticas preventivas na administração dos mesmos. Resultados: 88% dos participantes relataram ter recebido treinamento sobre o uso seguro de anestésicos locais. A lidocaína foi o anestésico mais frequentemente utilizado (94,5%). A maioria dos estudantes desconhecia a dose máxima segura de lidocaína. 51% dos participantes quase nunca ou nunca calcularam a dose máxima segura antes de administrar um anestésico local, 45% quase nunca ou nunca monitoraram os sinais vitais e 27% quase nunca ou nunca administraram o anestésico na presença de um instrutor. 75% dos participantes não se sentiram preparados para lidar com a toxicidade de anestésicos locais. Conclusão: Os estudantes entrevistados perceberam que não receberam treinamento adequado sobre o uso seguro de anestésicos locais e não aplicaram estratégias preventivas para reduzir os riscos ao administrar esses medicamentos.
