Safety and Revisit Related to Discharge the Sixty-one Spanish Emergency Department Medical Centers Without Hospitalization in Patients with COVID-19 Pneumonia. A Prospective Cohort Study UMC-Pneumonia COVID-19

ABSTRACT Background: Information is needed on the safety and efficacy of direct discharge from the emergency department (ED) of patients with COVID-19 pneumonia. Objectives: The objectives of the study were to study the variables associated with discharge from the ED in patients presenting with COVID-19 pneumonia, and study ED revisits related to COVID-19 at 30 days (EDR30d). Methods: Multicenter study of the SIESTA cohort including 1198 randomly selected COVID patients in 61 EDs of Spanish medical centers from March 1, 2020, to April 30, 2020. We collected baseline and related characteristics of the acute episode and calculated the adjusted odds ratios (aOR) for ED discharge. In addition, we analyzed the variables related to EDR30d in discharged patients. Results: We analyzed 859 patients presenting with COVID-19 pneumonia, 84 (9.8%) of whom were discharged from the ED. The variables independently associated with discharge were being a woman (aOR 1.890; 95%CI 1.176-3.037), age < 60 years (aOR 2.324; 95%CI 1.353-3.990), and lymphocyte count > 1200/mm3 (aOR 4.667; 95%CI 1.045-20.839). The EDR30d of the ED discharged group was 40.0%, being lower in women (aOR 0.368; 95%CI 0.142-0.953). A total of 130 hospitalized patients died (16.8%) as did two in the group discharged from the ED (2.4%) (OR 0.121; 95%CI 0.029-0.498). Conclusion: Discharge from the ED in patients with COVID-19 pneumonia was infrequent and was associated with few variables of the episode. The EDR30d was high, albeit with a low mortality.

Emulsión lipídica como antídoto al deterioro neurológico progresivo, tras la infiltración de altas dosis de anestésico local: a propósito de un caso / Lipid emulsion as an antidote to progressive neurological impairment after injection of high doses of local anesthetic: case report

La infiltración de anestésico local (AL) está cada vez más extendida como indicación en el tratamiento del dolor neuropático. La intoxicación por AL es poco frecuente pero grave, potencialmente mortal y de difícil manejo. Cursa con afectación del nivel de conciencia, crisis comiciales y bloqueos de la conducción cardiaca. La emulsión lipídica (EL) al 20 % es el único tratamiento específico descrito hasta la fecha y ha mejorado el pronóstico de estos casos. Presentamos el caso de un paciente con deterioro neurológico progresivo tras la infiltración de altas dosis de AL por un dolor neuropático refractario a otros tratamientos. El paciente fue tratado con emulsión lipídica al 20 % revirtiendo el cuadro neurológico de forma precoz y completa. La aparición de síntomas neurológicos progresivos en el contexto de una infiltración de anestésico local debe alertarnos sobre una posible intoxicación para iniciar tratamiento precoz con emulsión lipídica al 20 %, evitando un pronóstico infausto. Sin embargo, la prevención sigue siendo la herramienta principal.

The infiltration of local anesthetic (LA) is increasingly widespread as an indication in the treatment of neuropathic pain. AL poisoning is rare but serious, life-threatening entity and its management may be very difficult. It occurs with decreased level of consciousness, seizures and cardiac conduction blocks. The lipid emulsion (EL) 20% is the only specific treatment described to date and it has improved the prognosis of these patients. We report the case of a patient with progressive neurological deterioration after injection of high doses of LA for treat a neuropathic pain refractory to other treatments. The patient was treated with lipid emulsion 20% with reversing all the neurological symptoms early and completely. The occurrence of progressive neurological symptoms in the context of a local anesthetic infiltration, should alert us to a possible poisoning and to start early treatment with lipid emulsion 20%, to avoid poor prognosis. However, prevention remains the main tool.
