ABSTRACT
ABSTRACT Objective To review the long-term outcomes (functional status and psychological sequelae) of survivors of critical illnesses due to epidemic viral pneumonia before the COVID-19 pandemic and to establish a benchmark for comparison of the COVID-19 long-term outcomes. Methods This systematic review of clinical studies reported the long-term outcomes in adults admitted to intensive care units who were diagnosed with viral epidemic pneumonia. An electronic search was performed using databases: MEDLINE®, Web of Science™, LILACS/IBECS, and EMBASE. Additionally, complementary searches were conducted on the reference lists of eligible studies. The quality of the studies was assessed using the Newcastle-Ottawa Scale. The results were grouped into tables and textual descriptions. Results The final analysis included 15 studies from a total of 243 studies. This review included 771 patients with Influenza A, Middle East Respiratory Syndrome, and Severe Acute Respiratory Syndrome. It analyzed the quality of life, functionality, lung function, mortality, rate of return to work, rehospitalization, and psychiatric symptoms. The follow-up periods ranged from 1 to 144 months. We found that the quality of life, functional capacity, and pulmonary function were below expected standards. Conclusion This review revealed great heterogeneity between studies attributed to different scales, follow-up time points, and methodologies. However, this systematic review identified negative long-term effects on patient outcomes. Given the possibility of future pandemics, it is essential to identify the long-term effects of viral pneumonia outbreaks. This review was not funded.

ABSTRACT
@#Objective To explore the efficacy of prone positioning ventilation in patients with acute respiratory distress syndrome (ARDS) after acute Stanford type A aortic dissection (STAAD) surgery. Methods From November 2019 to September 2021, patients with ARDS who was placed prone position after STAAD surgery in the Xiamen Cardiovascular Hospital of Xiamen University were collected. Data such as the changes of blood gas, respiratory mechanics and hemodynamic indexes before and after prone positioning, complications and prognosis were collected for statistical analysis. Results A total of 264 STAAD patients had surgical treatment, of whom 40 patients with postoperative ARDS were placed prone position. There were 37 males and 3 females with an average age of 49.88±11.46 years. The oxygen partial pressure, oxygenation index and peripheral blood oxygen saturation 4 hours and 12 hours after the prone positioning, and 2 hours and 6 hours after the end of the prone positioning were significantly improved compared with those before prone positioning ventilation (P<0.05). The oxygenation index 2 hours after the end of prone positioning which was less than 131.42 mm Hg, indicated that the patient might need ventilation two or more times of prone position. Conclusion Prone position ventilation for patients with moderate to severe ARDS after STAAD surgery is a safe and effective way to improve the oxygenation.
ABSTRACT
Introducción: La lesión pulmonar aguda (TRALI) y la sobrecarga circulatoria (TACO) son las principales causas de morbilidad y mortalidad relacionadas con la transfusión. La TRALI se presenta durante o después de las transfusiones de plasma y sus derivados, o por inmunoglobulinas en alta concentración intravenosa; se asocia a procesos sépticos, cirugías y transfusiones masivas. La TACO es la exacerbación de manifestaciones respiratorias en las primeras 6 horas postransfusión. Reporte caso: Paciente de sexo masculino de 38 días de vida, ingresó al servicio de urgencias con un cuadro clínico de 8 días de evolución, caracterizado por dificultad respiratoria dado por retracciones subcostales y aleteo nasal sin otro síntoma asociado, con antecedentes de importancia de prematuridad y bajo peso al nacer. El reporte de hemograma arrojó cifras compatibles con anemia severa, por lo que requirió transfusión de glóbulos rojos empaquetados desleucocitados. El paciente presentó un cuadro respiratorio alterado en un periodo menor a 6 horas, por lo que se descartaron causas infecciosas y finalmente se consideró cuadro compatible con TRALI. Conclusiones: Se debe considerar una lesión pulmonar aguda relacionada con una transfusión de sangre si se produce una insuficiencia respiratoria aguda durante o inmediatamente después de la infusión de hemoderivados que contienen plasma.
Introduction: Acute lung injury (TRALI) and circulatory overload (TACO) are the main causes of transfusion-related morbidity and mortality. TRALI occurs during or after transfusions of plasma or its derivatives, or by immunoglobulins in high intravenous concentration; it is associated with septic processes, surgeries, and massive transfusions. TACO is the exacerbation of respiratory manifestations in the first 6 hours post transfusion. Case report: A 38-day-old male was admitted to the emergency department with clinical symptoms experienced over the course of 8 days and characterized by respiratory distress due to subcostal retractions and nasal flaring with no other associated symptoms. Important antecedents included prematurity and low birth weight. The hemogram report showed figures compatible with anemia, which benefited from transfusion of packed red blood cells without leukocytes. In a period of less than 6 hours, the patient presented altered respiratory symptoms, practitioners ruled out infectious causes and finally considered clinical signs compatible with TRALI. Conclusion: Acute lung injury related to blood transfusion should be considered if acute respiratory failure occurs during or immediately after infusion of plasma-containing blood products.
ABSTRACT
ABSTRACT Objective: To assess the effect of atelectasis during mechanical ventilation on the periatelectatic and normal lung regions in a model of atelectasis in rats with acute lung injury induced by lipopolysaccharide. Methods: Twenty-four rats were randomized into the following four groups, each with 6 animals: the Saline-Control Group, Lipopolysaccharide Control Group, Saline-Atelectasis Group, and Lipopolysaccharide Atelectasis Group. Acute lung injury was induced by intraperitoneal injection of lipopolysaccharide. After 24 hours, atelectasis was induced by bronchial blocking. The animals underwent mechanical ventilation for two hours with protective parameters, and respiratory mechanics were monitored during this period. Thereafter, histologic analyses of two regions of interest, periatelectatic areas and the normally-aerated lung contralateral to the atelectatic areas, were performed. Results: The lung injury score was significantly higher in the Lipopolysaccharide Control Group (0.41 ± 0.13) than in the Saline Control Group (0.15 ± 0.51), p < 0.05. Periatelectatic regions showed higher lung injury scores than normally-aerated regions in both the Saline-Atelectasis (0.44 ± 0.06 x 0.27 ± 0.74 p < 0.05) and Lipopolysaccharide Atelectasis (0.56 ± 0.09 x 0.35 ± 0.04 p < 0.05) Groups. The lung injury score in the periatelectatic regions was higher in the Lipopolysaccharide Atelectasis Group (0.56 ± 0.09) than in the periatelectatic region of the Saline-Atelectasis Group (0.44 ± 0.06), p < 0.05. Conclusion: Atelectasis may cause injury to the surrounding tissue after a period of mechanical ventilation with protective parameters. Its effect was more significant in previously injured lungs.
RESUMO Objetivo: Avaliar o efeito da atelectasia durante a ventilação mecânica nas regiões periatelectáticas e pulmonares normais em um modelo de atelectasia em ratos com lesão pulmonar aguda induzida por lipopolissacarídeo. Métodos: Foram distribuídos aleatoriamente 24 ratos em quatro grupos, cada um com 6 animais: Grupo Salina-Controle, Grupo Lipopolissacarídeo-Controle, Grupo Salina-Atelectasia e Grupo Lipopolissacarídeo-Atelectasia. A lesão pulmonar aguda foi induzida por injeção intraperitoneal de lipopolissacarídeo. Após 24 horas, a atelectasia foi induzida por bloqueio brônquico. Os animais foram submetidos à ventilação mecânica por 2 horas com parâmetros ventilatórios protetores, e a mecânica respiratória foi monitorada durante esse período. Em seguida, foram realizadas análises histológicas de duas regiões de interesse: as áreas periatelectásicas e o pulmão normalmente aerado contralateral às áreas atelectásicas. Resultados: O escore de lesão pulmonar foi significativamente maior no Grupo Controle-Lipopolissacarídeo (0,41 ± 0,13) do que no Grupo Controle-Solução Salina (0,15 ± 0,51), com p < 0,05. As regiões periatelectásicas apresentaram escores maiores de lesão pulmonar do que as regiões normalmente aeradas nos Grupos Atelectasia-Solução Salina (0,44 ± 0,06 versus 0,27 ± 0,74, p < 0,05) e Atelectasia-Lipopolissacarídeo (0,56 ± 0,09 versus 0,35 ± 0,04, p < 0,05). O escore de lesão pulmonar nas regiões periatelectásicas foi maior no Grupo Atelectasia-Lipopolissacarídeo (0,56 ± 0,09) do que na região periatelectásica do Grupo Atelectasia-Solução Salina (0,44 ± 0,06), p < 0,05. Conclusão: A atelectasia pode causar lesão no tecido circundante após um período de ventilação mecânica com parâmetros ventilatórios protetores. Seu efeito foi mais significativo em pulmões previamente lesionados.

Además, encontramos que, al realizar un modelo de predicción ajustado por edad, sexo, SOFA, APPS, shock, Indice de Charlson (ICh), se comportan como factores asociados a mortalidad el APPS, el sexo masculino (RPa: 1,48; IC 95% 1,09 a 2,049; p < 0,05) y el ICh (RPa: 1,11; IC 95% 1,02 a 1,21; p < 0,05). Conclusión: El APPS, el sexo masculino y el ICh son predictores de mortalidad en SDRA. por COVID-19 grave.
Background: Mortality in patients with severe COVID-19 who developed severe pneumonia and severe Acute Respiratory Distress Syndrome (ARDS) has been significant despite timely treatment. It is important to determine early predictors of disease that help us to stratify those patients with a higher risk of death. It is intended to study the behavior of the APPS score as a predictor of this, based on some reports of use and usefulness in non-COVID-19 ARDS. Aim: To determine if the APP score is useful as a predictor of mortality in ARDS due to severe COVID-19. Method: A retrospective cohort study was carried out, including patients from the Intensive Care Unit (ICU) with ARDS due to severe COVID-19 who were admitted to the ICU of the Trujillo Regional Teaching Hospital (HRDT) in the period March 2020 to March 2021. The usefulness of the APP score as a predictor of mortality in mentioned population was evaluated. Results: The APP score proved to be a factor associated with mortality in patients with ARDS and severe COVID-19 (APR 1.34; 95% CI 1.16 to 1.56; p < 0.001). We also found that when performing a prediction model adjusted for age, sex, SOFA, APP score, shock and Charlson Index (ICh) we found that the APP score, male sex (APR: 1.48; 95% CI 1.09 to 2.049; p < 0.05) and the ICh behave as factors associated with mortality (RPa: 1.11; 95% CI 1.02 to 1.21; p < 0.05). Conclusion: The APP score, male sex, and ICh are predictors of mortality in ARDS due to severe COVID-19.
ABSTRACT
Introducción: la pandemia de COVID-19 produjo una alta mortalidad en el mundo. Sin embargo, las presentaciones más críticas de la enfermedad han sido poco caracterizadas en nuestra región. Objetivo: estudiar la presentación clínica, evolución y mortalidad en pacientes ingresados en la unidad de medicina intensiva de un centro COVID-19 de referencia. Pacientes y método: estudio clínico, prospectivo, observacional de SARS-CoV-2 durante las primeras etapas de la pandemia en Uruguay. Se definió mortalidad en unidad de cuidados intensivos (UCI) como desenlace primario. Resultados: en 274 pacientes, la edad mediana fue de 65 años (IQR 54-73), el sexo masculino representó el 57% y el índice de Charlson tuvo una mediana de 3 (IQR 2-5). La mortalidad en UCI fue 59,9%. Las principales causas de muerte fueron: hipoxemia refractaria, disfunción orgánica múltiple y shock refractario. La edad (Odds Ratio (OR) = 1,06; IC de 95% 1,03 - 1,09), ocupación de camas (OR = 1,04, IC 95%: 1,02 - 1,07), sexo masculino (OR = 2,14, IC 95%: 0,93 - 5,06), ventilación mecánica invasiva (OR = 51,7, IC 95%: 16,5 - 208,6), coinfección al ingreso (OR = 2,34, IC 95%: 0,88 - 6,77) y enfermedad renal crónica previa (OR = 13,1, IC 95%: 2,29 - 129,2) fueron predictores independientes de mortalidad. La primera ola de la pandemia se produjo por la circulación de las variantes P.6 y P.1 del coronavirus, en una población con muy bajo porcentaje de vacunación (8%). Conclusiones: estos resultados en pacientes críticos aportan una descripción detallada del impacto de la pandemia por SARS-CoV-2 en un centro de referencia y constituyen una base para enfrentar futuros eventos epidémicos.
Introduction: COVID-19 has caused high mortality worldwide. However, the most critical presentations of the disease have been poorly characterized in our region. Objective: to study the clinical presentation, progression, and mortality in patients admitted to the Intensive Care Unit (ICU) of a COVID-19 Reference Center. Patients and methods: clinical, prospective, observational study of SARS-CoV-2 during the early stages of the pandemic in Uruguay. ICU mortality was defined as the primary outcome. Results: in 274 patients, the median age was 65 years (IQR 54-73), male gender accounted for 57%, and the Charlson Index was 3 (IQR 2-5). ICU mortality was 59.9%. The main causes of death were refractory hypoxemia, multiple organ dysfunction, and refractory shock. Age (Odds Ratio (OR) = 1.06; 95% CI 1.03 - 1.09), bed occupancy (OR= 1.04, 95% CI: 1.02 -1.07), male gender (OR= 2.14, 95% CI 0.93 - 5.06), invasive mechanical ventilation (OR= 51.7, 95% CI 16.5 - 208.6), coinfection at admission (OR= 2.34, 95% CI 0.88 - 6.77), and pre-existing chronic kidney disease (OR= 13.1, 95% CI 2.29 - 129.2) were independent predictors of mortality. The first wave of the pandemic was driven by the circulation of the P.6 and P.1 variants of the coronavirus in a population with a very low vaccination percentage (8%). Conclusions: these results in critical patients provide a detailed description of the impact of the SARS-CoV-2 pandemic in a reference center and serve as a foundation for addressing future epidemic events.

ABSTRACT
Los riesgos asociados a la neumonía por (SARS-CoV-2) es la generación de insuficiencia respiratoria secundaria que en algunos casos desencadenara al tan temido síndrome de distres respiratorio (SDRA); Informes sobre atención clínica, indican que tiene una incidencia (SDRA) de 3-10 % con necesidad de Asistencia Respiratoria Mecánica (ARM) en pacientes hospitalizados; por lo que dispositivos de oxigenación no invasivos siguen siendo una opción atractiva, de forma inicial. Caso clínico: mujer de 47 años con insuficiencia respiratoria secundario a neumonía por COVID-19, por la gravedad se indica su ingreso a terapia intensiva, pero por razones de falta de unidad es manejada en unidad respiratoria, con el uso de dispositivos de oxigenación de armado ARTESAL, de manera exitosa, con la utilización de CNAF-artesanal, se pretende mejorar el trabajo respiratorio, índices de oxigenación, mientras se da tratamiento a la infección por el COVID-19; el objetivo del presente caso es reportar el presente caso con evolución favorable a la literatura disponible. Discusión: El uso de terapia de oxigenación con dispositivo de Cánula Nasal de Alto Flujo, aún no ha sido normatizado en pacientes con COVID-19, pero existe evidencia clínica sobre los efectos beneficiosos en la insuficiencia respiratoria en neonatos mas no en adultos. Conclusión: El uso temprano de la CNAF-artesanal en la insuficiencia respiratoria resulta muy atractivo, más aún con dispositivo de confección artesanal, da una opción más al paciente fuera de UTI, pudiendo apoyar en evitar la intubación y su ingreso a ventilación mecánica.
The risks associated with pneumonia (SARS-CoV-2) is the generation of secondary respiratory failure that in some cases will trigger the much feared respiratory distress syndrome (ARDS); Reports on clinical care indicate that it has an incidence (ARDS) of 3-10% with the need for Mechanical Respiratory Assistance (ARM) in hospitalized patients; so non-invasive oxygenation devices remain an attractive option, initially. Clinical case: a 47-year-old woman with respiratory failure secondary to covid-19 pneumonia. Due to the severity, her admission to intensive care is indicated, but for reasons of lack of unity, she is managed in a common room, with the use of high-pressure oxygenation devices. ARTISAL assembly, successfully, with the use of CNAF-artisanal, is intended to improve the work of breathing, and oxygenation indices, while treating the infection by COVID-19; The objective of this case is to report the present case with a favorable evolution based on the available literature. Discussion: The use of oxygenation therapy with a High Flow Nasal Cannula device has not yet been standardized in patients with COVID-19, but there is clinical evidence on the beneficial effects in respiratory failure in neonates but not in adults. Conclusion: The early use of the artisan HFNC in respiratory failure is very attractive, even more so with an artisanal device, it gives the patient another option outside the ICU, being able to help avoid intubation and admission to mechanical ventilation.

Acute respiratory distress syndrome (ARDS) is an inflammatory process in the lungs that results in hypoxemia and decreased lung compliance. Invasive mechanical ventilation and prone positioning have proven benefits in the management of patients with severe ARDS. Post-extubation rehabilitation programs are equally important for the recovery of these patients. We are reporting the case of a 30-year-old male with severe ARDS where lung protective ventilation, timely intubation, early prone positioning, multidisciplinary communication, and post-discharge follow-up with teleconsultation were used under expert supervision in the successful management of the case
ABSTRACT
Abstract Objective: Among the mechanisms proposed for the development of bronchopulmonary dysplasia is the increase in the pulmonary inflammatory process and oxidative stress. Thus, the control of this process may result in improvements in bronchopulmonary dysplasia-related outcomes. This study aims to analyze the current scientific evidence regarding the use of budesonide, a potent anti-inflammatory drug, associated with a pulmonary surfactant to prevent bronchopulmonary dysplasia. Methods: A systematic review of the literature was performed on the Embase and MEDLINE platforms, and studies that compared budesonide with pulmonary surfactant versus pulmonary surfactant for treating respiratory distress syndrome were included. The primary outcome was a reduction in bronchopulmonary dysplasia or death. Results: Four randomized clinical trials and two observational studies were included in this systematic review. Three of the randomized clinical trials found a reduction in bronchopulmonary dysplasia or death in the use of budesonide with the surfactant, all the other studies (1 clinical trial and 2 observational studies) found no statistical differences between the groups for the primary outcomes. The three main studies showed a reduction in the primary outcome; however, all studies showed great heterogeneity regarding the type of surfactant (poractant or beractant) and the method of administration. Conclusion: Robust clinical studies, in a heterogeneous population, using porcine surfactant associated with budesonide, with administration by a minimally invasive technique are necessary for there to be a recommendation based on scientific evidence for its widespread use.
ABSTRACT
Resumo: Trata-se de um estudo metodológico para construção e validação de um cenário simulado com abordagem interprofissional, que permitirá a utilização no ensino e na educação permanente de profissionais da saúde por meio da metodologia ativa de simulação clínica. Este estudo foi realizado em uma universidade pública da região Sul do Brasil, objetivando construir e validar um cenário simulado para a pronação de pacientes críticos com Síndrome do Desconforto Respiratório Agudo (SDRA). Para isto, o estudo ocorreu em duas etapas: revisão de conteúdo, construção do cenário e de validação de conteúdo e de aparência por juízes. A revisão da literatura permitiu conhecer melhor sobre o manejo do paciente com SDRA, bem como subsidiar o desenvolvimento do caso clínico para o cenário. Um protocolo de pronação segura de um hospital universitário foi adotado. A partir desta revisão, a construção do cenário foi realizada considerando um roteiro validado. Como parte desta construção, surgiram como resultados: a descrição do cenário; a relação de materiais e equipamentos necessários para o desenvolvimento do cenário; o roteiro para o ator simulado; o guia de apoio ao facilitador; o guia de apoio ao participante; o quadro de apoio para tomada de decisão e o checklist de observação do desenvolvimento de competências e habilidades para cada profissão envolvida no cenário. Onze juízes participaram do estudo. Em relação ao perfil sociodemográfico dos juízes, a amostra foi predominantemente de enfermeiros (63,6%), seguido por fisioterapeutas (18,1%), médico (9%) e docente de enfermagem (9%). Para medir o percentual de concordância entre os juízes, adotou-se o Índice de Validade de Conteúdo (IVC) para os itens, que foram agrupados de acordo com unidades de significância. Após a leitura do cenário, os juízes responderam a um questionário do tipo Likert com 37 itens, que abordaram sobre a "Experiência Prévia do Participante/Briefing", "Conteúdo/Objetivos"; "Recursos Humanos"; "Preparo do Cenário", "Desenvolvimento do Cenário" e "Avaliação". Todos os itens obtiveram IVC superior ao desejável (0,80) e, portanto, foram considerados válidos. Além disso, os juízes realizaram sugestões de melhorias no cenário, aos quais foram acatadas ou rejeitas e discutidas com a literatura disponível. Este estudo permitiu criar e validar um cenário que reflete a prática real, ao mesmo tempo que oportuniza um ambiente seguro para os participantes e responde aos objetivos da aprendizagem.
Abstract: This is a methodological study for the construction and validation of a simulated scenario with an interprofessional approach, which will allow the use in the teaching and continuing education of health professionals through the active methodology of clinical simulation. This study was carried out in a public university in the South region of Brazil, aiming to build and validate a simulated scenario for the pronation of critically ill patients with Acute Respiratory Distress Syndrome (ARDS). To this end, the study occurred in two stages: content review, scenario construction, and content and appearance validation by judges. The literature review provided a better understanding of the management of the ARDS patient, as well as a basis for developing the clinical case for the scenario. A safe pronation protocol from a university hospital was adopted. Based on this review, the scenario was built using a validated script. As part of this process, the following results emerged: the description of the scenario; the list of materials and equipment needed for the development of the scenario; the script for the simulated actor; the facilitator support guide; the participant support guide; the decision support framework; and the checklist for observing the development of competencies and skills for each profession involved in the scenario. Eleven judges participated in the study. Regarding the sociodemographic profile of the judges, the sample was predominantly nurses (63.6%), followed by physical therapists (18.1%), physicians (9%), and nursing professors (9%). To measure the percentage of agreement between the judges, the Content Validity Index (CVI) was adopted for the items, which were grouped according to significance units. After reading the scenario, the judges answered a Likert-type questionnaire with 37 items, which addressed "Prior Participant Experience/Briefing", "Content/Objectives"; "Human Resources"; "Scenario Preparation", "Scenario Development", and "Evaluation". All items scored higher than desirable CVI (0.80) and were therefore considered valid. In addition, the judges made suggestions for improvements in the scenario, which were accepted or rejected and discussed with the available literature. This study made it possible to create and validate a scenario that reflects actual practice, while providing a safe environment for participants and meeting the learning objectives.

Since the declaration of COVID-19 infection as Pandemic in March, 2020, There has been rise in Multisystem Complications apart from regular Acute Respiratory Syndrome which is hallmark of COVID-19 infection. As the second wave surge of COVID-19 has occurred, most of the patients already suffered from dyspnoea but also rare complications like CVA (Infarct and Haemorrhage) , Seizure and altered sensorium related to Hypoxic Brain Injury. COVID-19 frequently presents with a state of altered coagulability which increases the risk of pulmonary embolism and other Thrombotic events such as Cerebrovascular events. This case report is limited to Neurological complications seen in COVID-19 Infected patients
ABSTRACT
ABSTRACT Objectives: To evaluate the factors associated with mortality in mechanically ventilated patients with acute respiratory distress syndrome due to COVID-19. Methods: This was a retrospective, multicenter cohort study that included 425 mechanically ventilated adult patients with COVID-19 admitted to 4 intensive care units. Clinical data comprising the SOFA score, laboratory data and mechanical characteristics of the respiratory system were collected in a standardized way immediately after the start of invasive mechanical ventilation. The risk factors for death were analyzed using Cox regression to estimate the risk ratios and their respective 95%CIs. Results: Body mass index (RR 1.17; 95%CI 1.11 - 1.20; p < 0.001), SOFA score (RR 1.39; 95%CI 1.31 - 1.49; p < 0.001) and driving pressure (RR 1.24; 95%CI 1.21 - 1.29; p < 0.001) were considered independent factors associated with mortality in mechanically ventilated patients with acute respiratory distress syndrome due to COVID-19. Respiratory system compliance (RR 0.92; 95%CI 0.90 - 0.93; p < 0.001) was associated with lower mortality. The comparative analysis of the survival curves indicated that patients with respiratory system compliance (< 30mL/cmH2O), a higher SOFA score (> 5 points) and higher driving pressure (> 14cmH2O) were more significantly associated with the outcome of death at 28 days and 60 days. Conclusion: Patients with a body mass index > 32kg/m2, respiratory system compliance < 30mL/cmH2O, driving pressure > 14cmH2O and SOFA score > 5.8 immediately after the initiation of invasive ventilatory support had worse outcomes, and independent risk factors were associated with higher mortality in this population.
RESUMO Objetivos: Avaliar os fatores associados à mortalidade em pacientes ventilados mecanicamente com síndrome o desconforto respiratório agudo por evolução da COVID-19. Métodos: Estudo de coorte retrospectiva, multicêntrica, que incluiu 425 pacientes adultos com COVID-19, ventilados mecanicamente, internados em 4 unidades de terapia intensiva. Foram coletados dados clínicos que compõem o escore SOFA, dados laboratoriais e características mecânicas do sistema respiratório, de forma padronizada, imediatamente após o início da ventilação mecânica invasiva. Os fatores de risco para óbito foram analisados por meio da regressão de Cox, para estimar as razões de risco, e seus respectivos IC95%. Resultados: Índice de massa corporal (RR de 1,17; IC95% 1,11 - 1,20; p < 0,001), escore SOFA (RR de 1,39; IC95% 1,31 - 1,49; p < 0,001) e driving pressure (RR de 1,24; IC95% 1,21 - 1,29; p < 0,001) foram considerados fatores independentes associados à mortalidade em pacientes ventilados mecanicamente com síndrome do desconforto respiratório agudo por COVID-19. Já a complacência do sistema respiratório (RR de 0,92; IC95% 0,90 - 0,93; p < 0,001) foi associada à menor mortalidade. A análise comparativa das curvas de sobrevida demonstra que pacientes com complacência do sistema respiratório (< 30mL/cmH2O), maior SOFA escore (> 5 pontos) e maior driving pressure (> 14cmH2O) apresentaram maior associação ao desfecho morte em 28 dias e 60 dias. Conclusão: Pacientes com índice de massa corporal > 32kg/m2, complacência do sistema respiratório < 30mL/cmH2O, driving pressure > 14cmH2O e SOFA escore > 5,8, imediatamente após o início da assistência ventilatória invasiva, apresentam piores desfechos no segmento, sendo fatores de risco independentes associados à maior mortalidade nessa população.
ABSTRACT
Se presenta el caso de un lactante de 38 semanas ingresado con distrés respiratorio a un nosocomio al norte del Perú. Tras intubación y conexión a ventilación mecánica, se administró tratamiento antimicrobiano y sedoanalgesia. Durante la hospitalización, el paciente presentó fiebre, tos con expectoración quintosa, rubicundez facial y desaturación. Se observó edema en párpados, manos y pies, pero la perfusión tisular se mantuvo adecuada. En el cuarto día, sufrió convulsión febril, sibilancias respiratorias y oliguria con hematuria. Se realizaron cambios en el tratamiento y se administraron transfusiones. Al día 7, con apoyo del panel de PCR múltiple (FilmArray®) para el diagnóstico etiológico de enfermedades infecciosas respiratorias, se diagnosticó colonización/infección por Acinetobacter baumanni multirresistente, la cual se acompañó con la detección de Serratia marcescens y virus sincicial respiratorio. Tras una estancia prolongada se logró la extubación exitosa el día 10. El día 24, el paciente fue dado de alta sin fiebre, signos vitales estables y sin requerir oxígeno, solo tratamiento para las convulsiones.
A case is presented of a 38-week-old infant admitted with respiratory distress to a hospital in northern Perú. After intubation and connection to mechanical ventilation, antimicrobial treatment and sedoanalgesia were administered. During hospitalizaron, the patient experienced fever, cough with quintose expectoration, facial rubor, and desaturation. Edema was observed in the eyelids, hands, and feet, but tissue perfusion remained adequate. On the fourth day, the patient had a febrile seizure, respiratory wheezing, and oliguria with hematuria. Treatment changes were made, and transfusions were administered. On the seventh day, using the FilmArray® multiplex PCR panel for etiological diagnosis of respiratory infectious diseases, colonization/infection by multidrug-resistant Acinetobacter baumanni was diagnosed, accompanied by the detection of Serratia marcescens and respiratory syncytial virus. After a prolonged stay, successfu extubation was achieved on day 10. On day 24, the patient was discharged without fever, stable vital signs, and without requiring oxygen only treatment for seizures.
ABSTRACT
ABSTRACT Objective: To identify factors associated with prolonged weaning and mortality in critically ill COVID-19 patients admitted to ICUs and under invasive mechanical ventilation. Methods: Between March of 2020 and July of 2021, we retrospectively recorded clinical and ventilatory characteristics of critically ill COVID-19 patients from the day of intubation to the outcome. We classified the patients regarding the weaning period in accordance with established criteria. A logistic regression analysis was performed to identify variables associated with prolonged weaning and mortality. Results: The study involved 303 patients, 100 of whom (33.0%) had a prolonged weaning period. Most of the patients were male (69.6%), 136 (44.8%) had more than 50% of pulmonary involvement on chest CT, and 93 (30.6%) had severe ARDS. Within the prolonged weaning group, 62% died within 60 days. Multivariate analysis revealed that lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were significantly associated with prolonged weaning, whereas age and prolonged weaning were significantly associated with mortality. Conclusions: Prolonged weaning can be used as a milestone in predicting mortality in critically ill COVID-19 patients. Lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were identified as significant predictors of prolonged weaning. These results might provide valuable information for healthcare professionals when making clinical decisions regarding the management of critically ill COVID-19 patients who are on mechanical ventilation.
RESUMO Objetivo: Identificar fatores associados ao desmame prolongado e à mortalidade em pacientes críticos com COVID-19 admitidos em UTI e sob ventilação mecânica invasiva. Métodos: Entre março de 2020 e julho de 2021, registramos retrospectivamente as características clínicas e ventilatórias de pacientes críticos com COVID-19 desde o dia da intubação até o desfecho. Os pacientes foram classificados quanto ao período de desmame de acordo com critérios estabelecidos. Foi realizada análise de regressão logística para identificar variáveis associadas ao desmame prolongado e à mortalidade. Resultados: O estudo incluiu 303 pacientes, 100 dos quais (33,0%) apresentaram período de desmame prolongado. A maioria dos pacientes era do sexo masculino (69,6%), 136 (44,8%) apresentaram mais de 50% de acometimento pulmonar na TC de tórax, e 93 (30,6%) apresentaram SDRA grave. No grupo desmame prolongado, 62% foram a óbito em 60 dias. A análise multivariada revelou que o acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação apresentaram associação significativa com o desmame prolongado, enquanto a idade e o desmame prolongado apresentaram associação significativa com a mortalidade. Conclusões: O desmame prolongado pode ser utilizado como marco na predição de mortalidade em pacientes críticos com COVID-19. O acometimento pulmonar maior que 50% na TC e a demora na primeira tentativa de retirada da ventilação mecânica após a intubação foram identificados como preditores significativos de desmame prolongado. Esses resultados podem fornecer informações valiosas para os profissionais de saúde na tomada de decisões clínicas sobre o manejo de pacientes críticos com COVID-19 e em ventilação mecânica.
ABSTRACT
Resumen ANTECEDENTES: Las mujeres embarazadas e infectadas con SARS-CoV-2 tuvieron 2.9 veces más probabilidad de requerir ventilación invasiva. La colecistitis aguda es la segunda indicación quirúrgica más común en el embarazo. En la búsqueda bibliográfica no se encontraron reportes de concomitancia de ambas enfermedades durante el embarazo, por este motivo se publica el reporte de caso clínico y se revisa la bibliografía. CASO CLÍNICO: Paciente de 32 años, en curso de las 23 semanas de embarazo. Debido a síntomas de COVID-19, con prueba PCR positiva, se hospitalizó para inicio de ventilación mecánica invasiva. Al noveno día de internamiento tuvo elevación de transaminasas y reporte de TAC de colecistitis aguda alitiásica. Se le indicó la colecistostomía percutánea, con la que se alivió el cuadro hepatobiliar. En el segundo tiempo quirúrgico se procedió a la cesárea. Tres días después experimentó mejoría ventilatoria y bioquímica gradual. A los 32 días de hospitalización se logró la intubación y, después de 54 días, se dio de alta del hospital, sin requerimiento de oxígeno suplementario. CONCLUSIONES: Encontrar, en conjunto con el síndrome de insuficiencia respiratoria aguda por COVID-19 grave que requiere ventilación mecánica invasiva, embarazo previable y colecistitis alitiásica pone en grave peligro a la embarazada y al equipo médico en múltiples dilemas médicos, quirúrgicos y bioéticos. La colecistostomía percutánea en pacientes con inestabilidad hemodinámica y la finalización del embarazo en caso de deterioro ventilatorio ante síndrome de insuficiencia respiratoria aguda es una opción controvertida. Lo conducente, sin duda, son los procedimientos basados en evidencia y las sesiones multidisciplinarias, incluyendo a la familia.
Abstract BACKGROUND: Pregnant women infected with SARS-CoV-2 were 2.9 times more likely to require invasive ventilation. Acute cholecystitis is the second most common surgical indication in pregnancy. In the literature search, no reports of concomitance of both diseases during pregnancy were found, for this reason the clinical case report is published and the literature is reviewed. CASE REPORT: 32-year-old female patient, in the course of 23 weeks of pregnancy. Due to symptoms of COVID-19, with positive PCR test, she was hospitalized for initiation of invasive mechanical ventilation. On the ninth day of hospitalization, she had elevated transaminases and CT report of acute cholecystitis alliasis. Percutaneous cholecystostomy was indicated, which relieved the hepatobiliary symptoms. In the second surgical stage, a cesarean section was performed. Three days later she experienced gradual ventilatory and biochemical improvement. After 32 days of hospitalization, intubation was achieved and, after 54 days, she was discharged from the hospital, without requiring supplemental oxygen. CONCLUSIONS: Finding, in conjunction with severe COVID-19 acute respiratory failure syndrome requiring invasive mechanical ventilation, pre-viable pregnancy, alliasic cholecystitis, places the pregnant woman and the medical team in serious medical, surgical, and bioethical dilemmas. Percutaneous cholecystostomy in patients with hemodynamic instability and termination of pregnancy in case of ventilatory deterioration in the face of acute respiratory failure syndrome is a controversial option. Evidence-based procedures and multidisciplinary sessions, including the family, are undoubtedly conducive.
ABSTRACT
ABSTRACT Objective: To assess whether the use of ELMO, a helmet for noninvasive ventilation created in Brazil, had a positive impact on the prognosis of patients with hypoxemic respiratory failure caused by severe COVID-19. Methods: This is a retrospective study of 50 critically ill COVID-19 patients. Epidemiological, clinical, and laboratory data were collected on ICU admission, as well as before, during, and after ELMO use. Patients were divided into two groups (success and failure) according to the outcome. Results: ELMO use improved oxygenation parameters such as Pao2, Fio2, and the Pao2/Fio2 ratio, and this contributed to a gradual reduction in Fio2, without an increase in CO2, as determined by arterial blood gas analysis. Patients in the success group had significantly longer survival (p < 0.001), as determined by the Kaplan-Meier analysis, less need for intubation (p < 0.001), fewer days of hospitalization, and a lower incidence of acute kidney injury in comparison with those in the failure group. Conclusions: The significant improvement in oxygenation parameters, the longer survival, as reflected by the reduced need for intubation and by the mortality rate, and the absence of acute kidney injury suggest that the ELMO CPAP system is a promising tool for treating ARDS and similar clinical conditions.
RESUMO Objetivo: Avaliar se o uso do ELMO, um capacete para ventilação não invasiva criado no Brasil, teve impacto positivo no prognóstico de pacientes com insuficiência respiratória hipoxêmica por COVID-19 grave. Métodos: Estudo retrospectivo com 50 pacientes críticos com COVID-19. Dados epidemiológicos, clínicos e laboratoriais foram coletados na admissão na UTI e antes, durante e após o uso do ELMO. Os pacientes foram divididos em dois grupos (sucesso e falha) de acordo com o desfecho. Resultados: O uso do ELMO melhorou parâmetros de oxigenação como Pao2, Fio2 e relação Pao2/Fio2, e isso contribuiu para uma redução gradual da Fio2, sem aumento do CO2, conforme determinado pela gasometria arterial. Os pacientes do grupo sucesso apresentaram sobrevida significativamente maior (p < 0,001), conforme determinado pela análise de Kaplan-Meier, menor necessidade de intubação (p < 0,001), menos dias de hospitalização e menor incidência de lesão renal aguda em comparação com os do grupo falha. Conclusões: A significativa melhora nos parâmetros de oxigenação, a maior sobrevida, refletida pela menor necessidade de intubação e pela taxa de mortalidade, e a ausência de lesão renal aguda sugerem que o sistema ELMO CPAP é uma ferramenta promissora para o tratamento da SDRA e de condições clínicas semelhantes.
ABSTRACT
SUMMARY OBJECTIVE: This study aimed to assess the effect of prone position on oxygenation and lung recruitability in patients with acute respiratory distress syndrome due to COVID-19 receiving invasive mechanical ventilation. METHODS: This prospective study was conducted in the intensive care unit between December 10, 2021, and February 10, 2022. We included 25 patients admitted to our intensive care unit with acute respiratory distress syndrome due to COVID-19 who had undergone prone position. We measured the respiratory system compliance, recruitment to inflation ratio, and PaO2/FiO2 ratio during the baseline supine, prone, and resupine positions. The recruitment to inflation ratio was used to assess the potential for lung recruitability. RESULTS: In the prone position, PaO2/FiO2 increased from 82.7 to 164.4 mmHg (p<0.001) with an increase in respiratory system compliance (p=0.003). PaO2/FiO2 decreased to 117 mmHg (p=0.015) in the resupine with no change in respiratory system compliance (p=0.097). The recruitment to inflation ratio did not change in the prone and resupine positions (p=0.198 and p=0.621, respectively). In all patients, the median value of respiratory system compliance during supine was 26 mL/cmH2O. In patients with respiratory system compliance<26 mL/cmH2O (n=12), respiratory system compliance increased and recruitment to inflation decreased from supine to prone positions (p=0.008 and p=0.040, respectively), whereas they did not change in those with respiratory system compliance ≥26 mL/cmH2O8 (n=13) (p=0.279 and p=0.550, respectively) (ClinicalTrials registration number: NCT05150847). CONCLUSION: In the prone position, in addition to the oxygenation benefit in all patients, we detected lung recruitment based on the change in the recruitment to inflation ratio with an increase in respiratory system compliance only in acute respiratory distress syndrome due to COVID-19 patients who have <26 mL/cmH2O baseline supine respiratory compliance.
ABSTRACT
The COVID-19 global pandemic has overwhelmed health services with large numbers of patients presenting to hospital, requiring immediate triage and diagnosis. Complications include acute respiratory distress syndrome, myocarditis, septic shock, and multiple organ failure. Point of care ultrasound is recommended for critical care triage and monitoring in COVID-19 by specialist critical care societies, however current guidance has mainly been published in webinar format, not a comprehensive review. Important limitations of point of care ultrasound include inter-rater variability and subjectivity in interpretation of imaging findings, as well as infection control concerns. A practical approach to clinical integration of point of care ultrasound findings in COVID-19 patients is presented to enhance consistency in critical care decision making, and relevant infection control guidelines and operator precautions are discussed, based on a narrative review of the literature.

The systemic inflammatory response caused by various pathogenic factors is a key stage in the development of acute respiratory distress syndrome (ARDS). At present, suppression of the inflammatory response and symptomatic support are main methods for the treatment of ARDS. Alveolar epithelial autophagy has an important role in the regulation of the inflammatory response in ARDS. Autophagy is a normal immune mechanism in the body, and it is a metabolic process by which phagocytes degrade intracellular components with the help of lysosomes to maintain intracellular homeostasis. Current studies have shown that pathogenic factors both inside and outside the lung can cause alveolar epithelial cells to form an unfavorable internal environment of hypoxia, starvation, infection, and even apoptosis by triggering inflammatory responses, leading to autophagy dysfunction. Excessive autophagy activation can continue to aggravate inflammatory responses. Autophagy related proteins such as Beclin1, microtubule-associated protein 1 light chain 3 (LC3), mammalian target of rapamycin (mTOR), and p62 are common autophagic markers in current research, which play a crucial role in regulating the autophagic process and the development of lung injury. Therefore, the expression of cellular autophagy genes can be used as early markers and important mechanisms of lung injury in septic ARDS. The Hippo signaling pathway is derived from the protein kinase Hippo in Drosophila, and the Hippo and autophagy are two conserved pathways that are essential for the protection of homeostasis in vivo. The mutual regulation of Hippo signaling pathway and autophagy is currently a hot topic in the academic community. This paper reviews the relevant literature to explore whether the Hippo signaling pathway can regulate cellular autophagy to alleviate the inflammatory response in septic ARDS, so as to provide further research directions for the treatment of ARDS.
