Caracterización del uso de emulsiones lipídicas como terapia antidotal en intoxicaciones diferentes a anestésicos locales en un centro de alta complejidad en Medellín

Introduction. Intravenous lipid emulsions (IVLE) are non-toxic fatty emulsions with phospholipids, currently approved for use in the treatment of poisoning, specifically those produced by local anesthetics. The purpose of this study is to characterize the use of IVLE in patients over 18 years of age, who presented intoxication by substances and medications other than local anesthetics, in a high complexity hospital in the city of Medellín, during the period between 2015 and 2020. Methodology. A retrospective descriptive study was carried out on cases that received IVLE as a treatment for their poisoning. The clinical records of the study population were reviewed. Information was collected about sociodemographic, clinical and paraclinical variables, and care. Univariate analysis of the variables of interest was performed. Results. Of the total of 1,966 poisonings, 51 (2.6%) cases caused by substances and medications other than local anesthetics, received ELI therapy between 2015 and 2020 and were included in the study. The median age of the participants was 27 years. 74.5% of the participants presented drug poisoning. The average IVLE dose received was 1,036 mL in 24 hours, a lower dose than the one calculated per kilo of weight, which had been on average 1,149 mL. 86.3% (n=44) of the cases presented neurotoxicity, and 76.5% (n=39) presented cardiotoxicity. Neurotoxicity improved in 34.7% and cardiotoxicity in 59.1% of individuals receiving ELI therapy. Conclusion. The application of IVLE was made in people mostly poisoned by antipsychotics, men, young people, less than half had compromised ventilation, and there was improvement in cardiotoxicity and neurotoxicity. There was a difference between the dose received and the one they should have received adjusted for weight. Resumen. Introducción.
