ECMO venovenoso durante procedimiento endoscópico de permeabilización de la vía aérea central en pacientes con riesgo vital: reporte de 2 casos / Use of venovenous extracorporeal membrane oxygenation (ECMO) during endoscopic treatment of central airway obstruction and vital risk: report of 2 cases

Resumen: La oxigenación por membrana extracorpórea (ECMO) es de gran utilidad al proveer soporte ventilatorio a pacientes con hipoxia, pero su utilidad en el manejo de pacientes con obstrucción central de la vía aérea y riesgo vital no ha sido frecuentemente usada. La broncoscopía intervencional como terapia bajo ventilación convencional es de alto riesgo en este tipo de pacientes, pero es posible lograr excelentes resultados al ser asociada a ECMO. Comunicamos el caso clínico de 2 pacientes que presentaban disnea en reposo y falla ven1ila1oria aguda ca1as1rófica debido a una obstrucción casi total del lumen traqueal, de causa tumoral. En ambos pacientes en forma urgente se inició soporte circulatorio mediante ECMO VV, mientras se efectuaba la resección tumoral broncoscópica. Luego de terminada la cirugía traqueal, en ambos pacientes se retiró el soporte, siendo decanulados sin eventos y con una buena evolución clínica posterior. Se discute el beneficio del soporte ECMO en este tipo de pacientes.

Abstract: In patients with severe central airway stenosis bronchoscopy-guided intervention therapy under conventional ventilation conveys a high risk. Extracorporeal membrane oxygenation (ECMO) provides very good cardiopulmonary support, but is rarely used in bronchoscopy-guided interventional therapy. We report 2 patients with resting dyspnea due to severe tumor tracheal obstruction and acute pulmonary failure with imminent vital risk. Both patients were cannulated and the ECMO circuit installed on a nearly emergency basis. Tumors were excised, and the patients weaned from cardiopulmonary bypass uneventfully. Subsequent clinical course was satisfactory in both cases. A brief discussion of this condition is included.

A resource that has been used for some years in Argentina was incorporated into the institution, but with the pandemic it took on vital importance; This is ECMO (extracorporeal membrane oxygenation). It is a life support modality of high complexity and cost, which is used in patients with severe respiratory or heart failure. ECMO consists of an extracorporeal circulation circuit that allows the elimination of carbon dioxide and oxygenation of the blood. There are two types of circuits: the veno-arterial, in which the circuit takes venous blood from the cavas and the right atrium, oxygenates it and then returns it to the larger circuit through the aorta, and the veno-arterial circuit. venous, which takes venous blood from the inferior vena cava and returns it oxygenated to the right atrium. The implementation of ECMO at the Sanatorio Allende requires important changes in a structured and integrated manner with a multidisciplinary plan aimed at patient care. Where the nurse's approach to the person in a critical situation subjected to ECMO is considered decisive, this professional being essential for the process. The health team is responsible for a continuous presence to monitor, monitor and prevent complications, as well as the management and coordination of care. The protocol was developed, emphasizing the strengths, weaknesses and The importance of this new challenge in the Coronary Unit service lies in acquiring new knowledge, technologies, unifying nursing care in post-wellness, recovery and patient safety[AU]

Dispositivos de asistencia ventricular en el shock cardiogénico posinfarto: importancia del soporte hemodinámico: reporte de caso / Ventricular assist devices in post-infarction cardiogenic shock: importance of hemodynamic support: case report / Dispositivos de assistência ventricular no choque cardiogênico pós-infarto: importância do suporte hemodinâmico: relato de caso

El shock cardiogénico posinfarto caracterizado por un estado de insuficiencia circulatoria sistémica requiere de un tratamiento precoz en vistas a restablecer la estabilidad hemodinámica y la función ventricular. Este consta de la reperfusión coronaria mediante revascularización miocárdica; en algunos casos es necesaria la utilización de dispositivos de asistencia ventricular. El ECMO venoarterial es un sistema de circulación extracorpórea que permite un soporte biventricular oxigenando la sangre y reintroduciéndola mediante un flujo continuo hacia la circulación arterial sistémica. El uso de dicho dispositivo en pacientes con shock cardiogénico ha mostrado una mejoría significativa de la sobrevida a 30 días en comparación con el uso del balón de contrapulsación intraaórtico. No obstante, sus potenciales complicaciones, como dificultad en el vaciamiento ventricular izquierdo, síndrome de Arlequín, sangrados e infecciones, hacen fundamental la formación y el trabajo en equipo del heart team. Un porcentaje no menor de estos pacientes presentarán una severa disfunción ventricular permanente, por lo que podrían ser candidatos a dispositivos de asistencia ventricular izquierda de larga duración tipo Heartmate III como puente al trasplante cardíaco, el cual ha mostrado resultados satisfactorios con una excelente sobrevida a mediano plazo.

Post-infarction cardiogenic shock characterized by a state of systemic circulatory failure requires early treatment in order to restore hemodynamic stability and ventricular function. This consists of coronary reperfusion through myocardial revascularization, requiring in some cases the use of ventricular assist devices. Veno-arterial ECMO is an extracorporeal circulation system that allows biventricular support by oxygenating the blood and reintroducing it through a continuous flow towards the systemic arterial circulation. The use of this device in patients with cardiogenic shock has shown a significant improvement in survival at 30 days compared to the use of intra-aortic balloon pump. However, its potential complications, such as difficulty in left ventricular emptying, Harlequin syndrome, bleeding and infections, make the training and teamwork of the heart team essential. A great percentage of these patients will present a severe permanent ventricular dysfunction, so they could be candidates for long-term mechanical circulatory support devices like Heartmate III as a bridge to transplant or myocardial recovery, or destination therapy, which has shown satisfactory results with excellent medium-term survival.

A ECMO venoarterial é um sistema de circulação extracorpórea que permite o suporte biventricular oxigenando o sangue e reintroduzindo-o através de um fluxo contínuo para a circulação arterial sistêmica. O uso desse dispositivo em pacientes com choque cardiogênico mostrou melhora significativa na sobrevida em 30 dias em relação ao uso de contrapulsação com balão intra-aórtico. No entanto, suas potenciais complicações, como dificuldade de esvaziamento ventricular esquerdo, síndrome de Harlequin, sangramentos e infecções, tornam imprescindível o treinamento e o trabalho em equipe do time do coração. Não uma pequena porcentagem desses pacientes apresentará uma condição ventricular permanente grave, podendo ser candidatos a dispositivos de assistência ventricular esquerda de longa duração do tipo Heartmate III como ponte para o transplante cardíaco, que tem demonstrado resultados satisfatórios com excelente sobrevida em médio prazo.

Application of extracorporeal membrane oxygenation in the treatment of persistent pulmonary hypertension of the newborn / 中国当代儿科杂志

OBJECTIVES@#To study the clinical value of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension of the newborn (PPHN).@*METHODS@#A retrospective analysis was performed on the medical data of 11 neonates with PPHN who were treated with ECMO in the Neonatal Intensive Care Unit of Zhongshan People's Hospital from January 2015 to December 2021, involving the neonates' general information, clinical diagnosis, laboratory results, duration of ECMO treatment, complications during ECMO treatment, length of hospital stay, and outcome.@*RESULTS@#Of the 11 neonates, 10 (91%) had successful weaning from ECMO, and 8 (73%) survived. For the 11 neonates, the mean duration of ECMO treatment was (81±50) hours (range: 26 to 185 hours), the mean duration of ventilator use was (198±105) hours (range: 57 to 392 hours), and the mean length of hospital stay was (22±15) days (range: 2 to 49 days). The oxygenation index and blood lactate level were significantly improved after 24 hours of ECMO treatment among the 11 neonates (P<0.05). Ten neonates had significantly reduced pulmonary artery pressure after 24 hours of ECMO treatment (P<0.05). One neonate had a progressive increase in the pulmonary artery pressure during EMCO treatment, succumbing to death. This neonate was diagnosed with alveolar capillary dysplasia based on the histopathological findings of the lung tissue and whole-exome sequencing results. Among the 11 children, 5 had intracranial hemorrhage, 1 had disseminated intravascular coagulation, 1 had gastric hemorrhage, 2 had pulmonary hemorrhage, 1 had renal insufficiency, and 3 had bleeding at the puncture site during ECMO treatment.@*CONCLUSIONS@#ECMO is effective for the treatment of PPHN, however, the high incidence of complications of ECMO treatment suggests that it is important to carefully assess the indications and timing of ECMO treatment and improve the management of ECMO, which can improve the weaning rate and survival rate.

Clinical analysis of 6 critically ill children with acute chlorine poisoning / 中华儿科杂志

Objective: To analyze the clinical characteristics and treatment of critically ill children with acute chlorine poisoning and explore the risk factors and effective strategies. Methods: This retrospective study collected the clinical data, including general state, clinical characteristics, treatment and follow-up(till 1 year and 6 months after discharge), of 6 critically ill children who were hospitalized in the Pediatric Intensive Care Unit of Beijing Children's Hospital due to acute chlorine poisoning in August 2019. Results: There were 6 children characterized by severe dyspnea in this accident, among whom 4 were boys and two girls, aged 4-12 years. When the accident occurred, they were within 5 m of the chlorine source. These patients underwent tracheal intubation and mechanical ventilation in 3.5-7.0 h after poisoning. The child who was the closest to the chlorine source (1.5 m) and took the longest time (5 min) to evacuate was the most severe one. He suffered hypoxia which could not be corrected by conventional mechanical ventilation and severe shock, then had veno-arterial extracorporeal membrane oxygenation(ECMO) treatment started 10 h after the accident. All the 6 children in this study survived. Following-up found no growth and developmental abnormality. The pulmonary function tests were normal except for one case with increased small airway resistance due to previous suspected asthma, and the lung CT, electhoencephalogram, and brain magnetic resonance imaging were all normal. Conclusions: Severe chlorine poisoning is mainly characterized by respiratory failure. Mechanical ventilation is often required within a few hours after poisoning. When conventional mechanical ventilation is ineffective, ECMO could save live. Timely treatment could improve prognosis.

Ultrasound-guided percutaneous cannulation for extracorporeal membrane oxygenation in children / 中华儿科杂志

Objective: To evaluate the effectiveness and safety of ultrasound-guided percutaneous cannulation for extracorporeal membrane oxygenation (ECMO) in children. Methods: In this retrospective observational study, 66 cases who underwent non-cardiac surgery ECMO in pediatric intensive care unit (PICU) of Shanghai Children's Hospital from May 2016 to April 2021 were collected. The demographics, model of ECMO support, type and size of arteriovenous cannulas, way of catheterization and complications were recorded and summarized. Patients were divided into percutaneous cannulation group and surgical cannulation group according to catheterization strategies. The demographics, duration of cannulation and ECMO support, ECMO weaning rate and hospital survival rate were compared among two groups. χ2 and nonparametric rank sum test were used for comparison. Results: Among the 66 patients who received ECMO, 38 were male and 28 were female, with age 44.5 (12.0, 83.5) months and weight 15.0 (10.0, 25.0) kg; 21 patients underwent percutaneous cannulation, with a success rate of 95% (20 cases). Point-of-care ultrasound was performed for all percutaneous cannulation cases. The duration of percutaneous cannulation was significantly shorter than that of surgical cannulation (26.0 (23.3, 30.3) vs. 57.0 (53.8, 64.0) min, Z=6.31, P<0.001). Successful percutaneous cannulation cases were aged 70.5 (23.8, 109.5) months, and their weight was 23.2 (13.6, 37.0) kg. Ten cases were initially given veno-venous (VV) ECMO support, and 10 cases were given veno-arterial (VA) ECMO support. ECMO arterial cannulas were sized from 8 F to 17 F, and venous cannulas sized from 10 F to 19 F. For VV-ECMO, the right internal jugular and femoral veins were used as vascular access, while VA-ECMO used right internal jugular vein-femoral artery or right femoral vein-left femoral artery approach. Only one patient suffered severe complication (superior vena cava perforation). There was no catheter-related bloodstream infection. Conclusion: Ultrasound-guided percutaneous cannulation for ECMO can be performed with a high rate of success and safety in children.

Early effect of extracorporeal membrane oxygenation and factors related to early outcome in adult patients with fulminant myocarditis / 中华心血管病杂志

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Risk factors for venoarterial-extracorporeal membrane oxygenation related nosocomial infection in children after cardiac surgery / 中南大学学报(医学版)

OBJECTIVES@#Extracorporeal membrane oxygenation (ECMO) is an extracorporeal life support strategy for the treatment of critically ill children with reversible heart and lung failure, increasingly being used in patients with low cardiac output after cardiac surgery. However, the mortality of patients is closely related to the complications of ECMO, especially bleeding, thrombosis, and infection, ECMO-related nosocomial infection has become a challenge to the success of ECMO. This study aims to analyze the incidence and risk factors for venoarterial-ECMO (VA-ECMO)-related nosocomial infections in children after cardiac surgery.@*METHODS@#We retrospectively collected the data of patients who underwent VA-ECMO treatment after pediatric cardiac surgery in the Second Xiangya Hospital of Central South University from July 2015 to March 2021, and divided them into an infected group and a non-infected group. The clinical characteristics of the 2 groups of patients, VA-ECMO-related nosocomial infection factors, pathogenic microorganisms, and patient mortality were compared. Logistic regression was used to analyze the risk factors for nosocomial infection related to VA-ECMO after cardiac surgery.@*RESULTS@#Of the 38 pediatric patients, 18 patients (47.37%) had VA-ECMO related nosocomial infection, served as the infected group, including 7 patients with blood infections and 11 respiratory tract infections. Gram-negative pathogens (16 strains, 88.9%) were the main bacteria, such as Acinetobacter baumannii (6 strains), Klebsiella pneumoniae (3 strains), and Stenotrophomonas maltophilia (3 strains). Compared with the non-infected group (n=20), the infection group had longer time of cardiopulmonary bypass, time of myocardial block, and time of VA-ECMO assistance (All P<0.05). Multivariate logistic regression analysis showed that time of cardiopulmonary bypass (OR=1.012, 95% CI 1.002 to 1.022; P=0.021) was an independent risk factor for ECMO-related nosocomial infection. The number of surviving discharges in the infected group was less than that in the non-infected group (1 vs 11, P<0.05).@*CONCLUSIONS@#Cardiopulmonary bypass time is an independent risk factor for VA-ECMO-related nosocomial infection in children after cardiac surgery. Shortening the duration of extracorporeal circulation may reduce the incidence of VA-EMCO-related nosocomial infections in children after cardic surgery. The occurrence of VA-ECMO-related nosocomial infections affects the number of patient's discharge alive.

Extracorporeal Membrane Oxygenation-Related Nosocomial Infection after Cardiac Surgery in Adult Patients

Abstract Introduction: The evaluation of extracorporeal membrane oxygenation-related nosocomial infection (ECMO-related NI) in a homogeneous cohort remains scarce. This study analyzed ECMO-related NI in adult patients who have undergone cardiac surgery. Methods: From January 2012 to December 2017, 322 adult patients who have received ECMO support after cardiac surgery were divided into the infection group (n=131) and the non-infection group (n=191). ECMO-related NI was evaluated according to demographic data, surgical procedures, and ECMO parameters. Results: The incidence of ECMO-related NI was 85.4 cases per 1000 ECMO days. Acinetobacter baumannii was the most common pathogen causing blood stream infection and respiratory tract infection. Prolonged duration of surgery (P=0.042) and cardiopulmonary bypass assist (P=0.044) increased the risk of ECMO-related NI. Body mass index (odds ratio [OR]: 1.077; 95% confidence interval [CI]: 1.004-1.156; P=0.039) and duration of ECMO support (OR: 1.006; 95% CI: 1.003-1.009; P=0.0001) were the independent risk factors for ECMO-related NI. Duration of ECMO support > 144 hours (OR: 2.460; 95% CI: 1.155-7.238; P<0.0001) and ECMO-related NI (OR: 3.726; 95% CI: 1.274-10.895; P=0.016) increased significantly the risk of in-hospital death. Conclusion: Prolonged duration of ECMO support was an independent risk factor for NI. Surgical correcting latent causes of cardiopulmonary failure and shortening duration of ECMO whenever possible would reduce susceptibility to NI.

Oxigenación por membrana extracorpórea (ECMO): una mirada desde la prevención de Infecciones Asociadas a la Atención en Salud (IAAS) / Extracorporeal membrane oxygenation (ECMO): an infection control perspective

Resumen La aparición de la enfermedad por SARS-CoV-2 el año 2020 nos enfrentó a un aumento creciente y exponencial de pacientes con riesgo vital por falla respiratoria catastrófica y multisistémica que deben ser sometidos a ECMO para sobrevivir. Esto ha generado en nuestro país la aparición de Unidades de Tratamiento (ECMO) en hospitales en que antes no se disponía de este recurso o se realizaba como parte de las intervenciones en Unidades de Cuidados Intensivos (UCI), lo que constituye un nuevo desafío a los programas de control y prevención de infecciones de los centros de salud. Dado que al momento de la redacción de este documento no existe normativa nacional específica que se refiera a este tema, se propone un enfoque para prevención, control y vigilancia de infecciones asociadas a atención de salud en pacientes ECMO. Se presenta una revisión de los riesgos específicos a que están expuestos estos pacientes, definiendo qué medidas de prevención se requieren, proponiendo un conjunto de medidas específicas para instalación y mantención, así como orientación respecto de antibioprofilaxis y se sugiere qué eventos infecciosos vigilar.

Abstract The advent of SARS-CoV-2 disease in 2020 confronts us with a growing and exponential increase in patients at life risk due to catastrophic and multisystemic respiratory failure in need of extracorporeal membrane oxygenation (ECMO) to survive. This has generated in our country the establishment of ECMO treatment Units in hospitals where it was not carried out before or was carried out as part the interventions in Intensive Care Units (ICU), becoming a new challenge to the infection control and prevention programs. Given that at the time of writing this document there are no specific national regulations that refer to this issue, an approach is proposed for the prevention control and surveillance of nosocomial acquired infections in ECMO patients. A review of the specific risks to which these patients are exposed is presented, defining which prevention measures are required, proposing a specific bundle for installation and maintenance, as well as guidance regarding antibioprophylaxis and suggesting which infectious events to monitor.

DISCUSSION: In our study we found a low incidence of this pathology, a high severity index an a favorable evolution in most cases.

Oxigenação por membrana extracorpórea na insuficiência respiratória em crianças: os anos antes e depois da pandemia de H1N1 de 2009 / Extracorporeal membrane oxygenation for respiratory failure in children: the years before and after the 2009 H1N1 pandemic

RESUMO Objetivo: Avaliar o impacto no número de casos de oxigenação por membrana extracorpórea e as taxas de sobrevivência nos anos seguintes à pandemia de H1N1 de 2009. Métodos: Avaliaram-se dois períodos distintos de utilização de oxigenação por membrana extracorpórea como suporte para insuficiência respiratória em crianças, por meio da análise de conjuntos de dados da Extracorporeal Life Support Organization. Foram construídos modelos autorregressivos integrados de médias móveis para estimar os efeitos da pandemia. O ano de 2009 foi o ano de intervenção (epidemia de H1N1) em um modelo de séries temporais interrompidas. Os dados colhidos entre 2001 e 2010 foram considerados pré-intervenção e os obtidos entre 2010 e 2017 como pós-intervenção. Resultados: Em comparação com o período entre 2001 e 2010, o período entre 2010 e 2017 mostrou aumento das taxas de sobrevivência (p < 0,0001), com melhora significante da sobrevivência quando se realizou oxigenação por membrana extracorpórea nos casos de insuficiência aguda por pneumonia viral. Antes do ponto de nível de efeito (2009), o modelo autorregressivo integrado de médias móveis mostrou aumento de 23 casos de oxigenação por membrana extracorpórea ao ano. Em termos de sobrevivência, a curva mostra que não houve aumento significante das taxas de sobrevivência antes de 2009 (p = 0,41), porém o nível de efeito foi próximo à significância após 2 anos (p = 0,05), com aumento de 6% na sobrevivência. Em 4 anos, ocorreu aumento de 8% (p = 0,03) na sobrevivência, e, 6 anos após 2009, a sobrevivência mostrou aumento de até 10% (p = 0,026). Conclusão: Nos anos após 2009, ocorreu significante e progressivo aumento global das taxas de sobrevivência com oxigenação por membrana extracorpórea para todos os casos, principalmente em razão de melhoras tecnológicas e dos protocolos de tratamento para insuficiência respiratória aguda relacionada à pneumonia viral e a outras condições respiratórias.

ABSTRACT Objective: To evaluate whether there was any impact on the number of pediatric extracorporeal membrane oxygenation runs and survival rates in the years subsequent to the 2009 pandemic. Methods: We studied two different periods of extracorporeal membrane oxygenation support for respiratory failure in children by analyzing datasets from the Extracorporeal Life Support Organization. Autoregressive integrated moving average models were constructed to estimate the effect of the pandemic. The year 2009 was the year of intervention (the H1N1 epidemic) in an interrupted time series model. Data collected from 2001 - 2010 were considered preintervention, and data collected from 2010 - 2017 were considered postintervention. Results: There was an increase in survival rates in the period 2010 - 2017 compared to 2001 - 2010 (p < 0.0001), with a significant improvement in survival when extracorporeal membrane oxygenation was performed for acute respiratory failure due to viral pneumonia. The autoregressive integrated moving average model shows an increase of 23 extracorporeal membrane oxygenation runs per year, prior to the point of the level effect (2009). In terms of survival, the preslope shows that there was no significant increase in survival rates before 2009 (p = 0.41), but the level effect was nearly significant after two years (p = 0.05), with a 6% increase in survival. In four years, there was an 8% (p = 0.03) increase in survival, and six years after 2009, there was up to a 10% (p = 0.026) increase in survival. Conclusion: In the years following 2009, there was a significant, global incremental increase in the extracorporeal membrane oxygenation survival rates for all runs, mainly due to improvements in the technology and treatment protocols for acute respiratory failure related to viral pneumonia and other respiratory conditions.

Síndrome da encefalopatia posterior reversível em paciente com COVID-19 submetida à oxigenação por membrana extracorpórea / Posterior reversible encephalopathy syndrome in a patient submitted to extracorporeal membrane oxygenation for COVID-19

RESUMO Uma mulher com 63 anos de idade compareceu ao pronto-socorro com história aguda de febre, prostração e dispneia. Recebeu diagnóstico de quadro grave da COVID-19 e síndrome do desconforto respiratório agudo. Apesar de suporte clínico intensivo, cumpriu os critérios para ser submetida à oxigenação venovenosa por membrana extracorpórea. No dia 34, após 7 dias de desmame da sedação com evolução positiva de seu quadro neurológico, apresentou uma crise tônico-clônica generalizada limitada, não relacionada com desequilíbrio hidroeletrolítico ou metabólico, que levou à necessidade de investigação diagnóstica. Seus exames de imagem cerebral revelaram síndrome da encefalopatia posterior reversível. Este caso enfatiza a questão das complicações neurológicas em pacientes com COVID-19 grave e a importância do diagnóstico e suporte precoces.

ABSTRACT A 63-year-old woman presented to the emergency department with an acute history of fever, prostration and dyspnea. She was diagnosed with severe COVID-19 acute respiratory distress syndrome and, despite optimized critical care support, met the indications for veno-venous extracorporeal membrane oxygenation. On day 34, after 7 days of wean sedation with a positive evolution of neurologic status, she presented a limited generalized tonic-clonic seizure not related to hydroelectrolytic or metabolic imbalance, which led to a diagnostic investigation; her brain imaging tests showed a posterior reversible encephalopathy syndrome. This case emphasizes the issue of neurological complications in patients with severe COVID-19 infection and the importance of early diagnosis and support.
