Post-pandemic acute respiratory distress syndrome: A New Global Definition with extension to lower-resource regions.

Acute respiratory distress syndrome (ARDS), first described in 1967, is characterized by acute respiratory failure causing profound hypoxemia, decreased pulmonary compliance, and bilateral CXR infiltrates. After several descriptions, the Berlin definition was adopted in 2012, which established three categories of severity according to hypoxemia (mild, moderate and severe), specified temporal aspects for diagnosis, and incorporated the use of non-invasive ventilation. The COVID-19 pandemic led to changes in ARDS management, focusing on continuous monitoring of oxygenation and on utilization of high-flow oxygen therapy and lung ultrasound. In 2021, a New Global Definition based on the Berlin definition of ARDS was proposed, which included a category for non-intubated patients, considered the use of SpO2, and established no particular requirement for oxygenation support in regions with limited resources. Although debates persist, the continuous evolution seeks to adapt to clinical and epidemiological needs, and to the search of personalized treatments.

Adult respiratory distress syndrome (ARDS) due to omeprazole-induced drug reaction with eosinophilia and systemic symptoms (DRESS): Case report and review of the literature.

Eosinophilia in not an uncommon findings in the intensive care unit (ICU); however, DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome, which is characterized by a hypersensitivity reaction to drugs and manifests as eosinophilia, systemic involvement and maculopapular erythematous rash 2-6 weeks after exposure to the offending drug, is an exceptional occurrence. We present the first case described in the literature of DRESS syndrome with pulmonary involvement in the form of interstitial pneumonitis and persistent adult respiratory distress syndrome (ARDS) secondary to proton pump inhibitors (PPI). The patient made a good recovery after withdrawal of the offending drug and long-term treatment with systemic corticosteroids. We also present a systematic review of all cases of DRESS with pulmonary involvement in the form of interstitial pneumonitis and cases of PPI-induced DRESS published to date; none of these describe pulmonary involvement.

Effectiveness of Helmet-CPAP in mild to moderate coronavirus type 2 hypoxemia: An observational study.

OBJECTIVE: To determine the relative effectiveness of Helmet-CPAP (H_CPAP) with respect to high-flow nasal cannula oxygen therapy (HFNO) in avoiding greater need for intubation or mortality in a medium complexity hospital in Chile during the year 2021. DESIGN: Cohort analytical study, single center. SETTING: Units other than intensive care units. PATIENTS: Records of adults with mild to moderate hypoxemia due to coronavirus type 2. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Need for intubation or mortality. RESULTS: 159 patients were included in the study, with a ratio by support of 2:10 (H_CPAP:HFNO). The 46.5% were women, with no significant differences by sex according to support (p = 0.99, Fisher test). The APACHE II score, for HFNO, had a median of 10.5, 3.5 units higher than H_CPAP (p < 0.01, Wilcoxon rank sum). The risk of intubation in HFNO was 42.1% and in H_CPAP 3.8%, with a significant risk reduction of 91% (95% CI: 36.9%-98.7%; p < 0.01). APACHE II does not modify or confound the support and intubation relationship (p > 0.2, binomial regression); however, it does confound the support and mortality relationship (p = 0.82, RR homogeneity test). Despite a 79.1% reduction in mortality risk with H_CPAP, this reduction was not statistically significant (p = 0.11, binomial regression). CONCLUSIONS: The use of Helmet CPAP, when compared to HFNO, was an effective therapeutic ventilatory support strategy to reduce the risk of intubation in patients with mild to moderate hypoxemia caused by coronavirus type 2 in inpatient units other than intensive care. The limitations associated with the difference in size, age and severity between the arms could generate bias.

Characteristics and risk factors associated with mortality during the first cycle of prone secondary to ARDS due to SARS-CoV-2 pneumonia / Características y factores de riesgo asociados a mortalidad durante el primer ciclo de prono por SDRA secundario a neumonía por SARS-CoV-2

Objective To analyze characteristics, changes in oxygenation, and pulmonary mechanics, in mechanically ventilated patients with ARDS due to SARS-CoV-2 treated with prone position and evaluate the response to this maneuver.Design Cohort study including patients with PaO2/FiO2 <150mmHg requiring prone position over 18 months. We classified patients according to PaO2/FiO2 changes from basal to 24h after the first prone cycle as: 1) no increase 2) increase <25%, 3) 25%–50% increase 4) increase >50%. Setting 33-bed medical-surgical Intensive Care Unit (ICU) in Argentina. Patients 273 patients. Interventions None. Main variables of interest Epidemiological characteristics, respiratory mechanics and oxygenation were compared between survivors and non-survivors. Independent factors associated with in-hospital mortality were identified. Results Baseline PaO2/FiO2 was 116 [97–135]mmHg (115 [94–136] in survivors vs. 117 [98–134] in non-survivors; p=0.50). After prone positioning, 22 patients (8%) had similar PaO2/FiO2 values; 46(16%) increased PaO2/FiO2 ≤25%; 55 (21%) increased it 25%–50%; and 150 (55%), >50%. Mortality was 86%, 87%, 72% and 50% respectively (p<0.001). Baseline PaO2/FiO2, <100mmHg did not imply that patients were refractory to prone position. Factors independently associated with mortality were age, percentage increase in PaO2/FiO2 after 24h being in prone, and number of prone cycles. Conclusions Older patients unable to improve PaO2/FiO2 after 24h in prone position and who require >1 cycle might early receive additional treatments for refractory hypoxemia. After the first 24h in the prone position, a low percentage of PaO2/FiO2 increase over baseline, beyond the initial value, was independently associated with higher mortality. (AU)

Objetivo Analizar las características, cambios en la oxigenación y mecánica pulmonar, en pacientes ventilados mecánicamente con SDRA por SARS-CoV-2 tratados con posición prona, y evaluar la respuesta a esta maniobra. Diseño Estudio de cohorte que incluyó pacientes con PaO2/FiO2 <150mmHg que requirieron posición prona durante 18 meses. Se clasificaron los pacientes según los cambios de PaO2/FiO2 desde el basal y 24horas después del primer ciclo prono como: 1) Sin aumento 2) Aumento <25%, 3) 25–50% de aumento 4) Aumento >50%. Ambito Unidad de Cuidados Intensivos (UCI) médico-quirúrgica de 33 camas en Argentina. Pacientes 273 pacientes. Intervenciones Ninguna. Principales variables de interés Se compararon características epidemiológicas, mecánica respiratoria y oxigenación entre sobrevivientes y no sobrevivientes. Se identificaron factores independientes asociados a la mortalidad hospitalaria. Resultados La PaO2/FiO2 basal fue de 116 [97–135]mmHg (115 [94–136] en sobrevivientes vs. 117 [98–134] en no sobrevivientes; p=0,50). Después de la posición prona, 22 pacientes (8%) tenían valores similares de PaO2/FiO2; 46 (16%) aumentaron PaO2/FiO2 ≤25%; 55 (21%) lo aumentaron 25%–50%; y 150 (55%), >50%. La mortalidad fue de 86%, 87%, 72% y 50% respectivamente (p<0,001). La PaO2/FiO2 basal, <100mmHg no implicó que los pacientes fueran refractarios a la posición prona. Los factores asociados independientemente con la mortalidad fueron la edad, el aumento porcentual de PaO2/FiO2 después de 24horas en prona, y el número de ciclos prono. Conclusiones Los pacientes mayores que no pueden mejorar PaO2/FiO2 después de 24 horas en posición prona y que requieren más de 1 ciclo podrían recibir tratamientos adicionales para la hipoxemia refractaria. Después de las primeras 24horas en decúbito prono, un bajo porcentaje de aumento de PaO2/FiO2 sobre el valor basal, más allá del valor inicial, se asoció de forma independiente con una mayor mortalidad.

Decúbito prono en el tercer trimestre del embarazo durante la era COVID-19: un abordaje transdisciplinar / Prone position in the third trimester of pregnancy during the COVID-19 era: A transdisciplinary approach

Existe evidencia muy limitada respecto del uso de la ventilación en decúbito prono como parte del tratamiento de un síndrome de distrés respiratorio agudo severo para pacientes en periodo de gestación. Actualmente las recomendaciones para el manejo ventilatorio invasivo en esta población son muy escasas y se basan en la extrapolación de las conclusiones obtenidas en estudios de pacientes no gestantes. La literatura disponible asevera que la anatomía y la fisiología de la gestante experimentan complejos cambios adaptativos que deben ser considerados durante el soporte ventilatorio invasivo y el prono. Con la ventilación en decúbito prono, los beneficios obtenidos para el binomio superan ampliamente a los eventuales riesgos. La programación adecuada del ventilador mecánico se correlaciona con un concepto claro y simple: la individualización del soporte. De todas maneras, la decisión del momento oportuno para la interrupción del embarazo debe fundamentarse con un adecuado juicio clínico multidisciplinario y además debe ser respaldado con una estricta monitorización fetal.(AU)

There is very limited evidence regarding the use of prone position as part of the treatment of severe acute respiratory distress syndrome in pregnant patients. Currently, recommendations for invasive ventilatory management in this population are very scarce and are based on the extrapolation of conclusions obtained in studies of non-pregnant patients. The available literature asserts that the anatomy and physiology of the pregnant woman undergoes complex adaptive changes that must be considered during invasive ventilatory support and prone position. With prone ventilation, the benefits obtained for the couple far outweigh the eventual risks. Adequate programming of the mechanical ventilator correlates with a clear and simple concept: individualization of support. In any case, the decision on the timing of termination of pregnancy should be based on adequate multidisciplinary clinical judgment and should be supported by strict monitoring of the product.(AU)

Puntaje APP como predictor de mortalidad en pacientes con síndrome de dificultad respiratoria agudo grave por COVID-19 en un hospital referencial del norte del Perú

Introducción: La mortalidad por pacientes por COVID-19 grave que desarrollaban neumonía grave y síndrome de dificultad respiratoria agudo (SDRA) grave ha sido significativa a pesar del tratamiento oportuno. Es importante determinar predictores tempranos de enfermedad que nos ayuden a estratificar aquellos pacientes con mayor riesgo de fallecer. Se pretende estudiar el comportamiento del puntaje APP (APPS) como predictor de ello, basados en algunos reportes de uso y utilidad en el SDRA. no COVID-19. Objetivo: Determinar si el APPS es útil como predictor de mortalidad en SDRA. por COVID-19 grave. Pacientes y Método: Se realizó un estudio tipo cohorte retrospectivo, incluyendo pacientes de la Unidad de Cuidados Intensivos (UCI), con SDRA. por COVID-19 grave, que ingresaron a la UCI del Hospital Regional Docente de Trujillo (HRDT) en el período abril 2020- abril 2021. Se evalúo la utilidad del APPS como predictor de mortalidad em dicha población. Resultados: El APPS demostró ser un factor asociado a mortalidad en pacientes con SDRA. y COVID-19 grave (RPa 1,34; IC 95% 1,16 a 1,56; p < 0,001). 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.

Efectos cerebrales del oxígeno y el dióxido de carbono en el síndrome de dificultad respiratoria aguda

Introducción: El síndrome de dificultad respiratoria aguda producido por la COVID-19 provoca alteraciones en el intercambio de oxígeno y la excreción de dióxido de carbono con consecuencias neurológicas. Objetivo: Describir las implicaciones del oxígeno y el dióxido de carbono sobre la dinámica cerebral durante el tratamiento ventilatorio del síndrome de dificultad respiratoria aguda en el accidente cerebrovascular. Métodos: Se realizó una búsqueda en bases referenciales como: PubMed/Medline, SciELO, Google Académico y BVS Cuba. Los términos incluidos fueron brain-lung crosstalk, ARDS, mechanical ventilation, COVID-19 related stroke, ARDS related stroke y su traducción al español. Fueron referenciados libros de neurointensivismo y ventilación mecánica artificial. El período de búsqueda incluyó los últimos 20 años. Se seleccionaron 46 bibliografías que cumplieron con los criterios de selección. Resultados: Se ha descrito que los niveles de oxígeno y dióxido de carbono participan en la neurorregulación vascular en pacientes con daño cerebral. Algunas alteraciones alusivas son la vasodilatación cerebral refleja o efectos vasoconstrictores con reducción de la presión de perfusión cerebral. Como consecuencia aumenta la presión intracraneal y aparecen afectaciones neurocognitivas, isquemia cerebral tardía o herniación del tronco encefálico. Conclusiones: El control de la oxigenación y la excreción de dióxido de carbono resultaron cruciales para mantener la homeostasis neuronal, evita la disminución de la presión de perfusión cerebral y el aumento de la presión intracraneal. Se sugiere evitar la hipoxemia e hiperoxemia, limitar o eludir la hipercapnia y usar hiperventilación hipocápnica solo en condiciones de herniación del tallo encefálico.

Introduction: The acute respiratory distress syndrome produced by COVID-19 causes alterations in the exchange of oxygen and the excretion of carbon dioxide with neurological consequences. Objective: To describe the implications of oxygen and carbon dioxide on brain dynamics during ventilatory treatment of acute respiratory distress syndrome in stroke. Methods: A search was carried out in referential bases such as PubMed/Medline, SciELO, Google Scholar and VHL Cuba. The terms included were brain-lung crosstalk, ARDS, mechanical ventilation, COVID-19 related stroke, ARDS related stroke and their translation into Spanish. Books on neurointensive care and artificial mechanical ventilation were referenced. The search period included the last 20 years. Forty six bibliographies that met the selection criteria were selected. Results: Oxygen and carbon dioxide levels have been described to participate in vascular neuroregulation in patients with brain damage. Some allusive alterations are reflex cerebral vasodilatation or vasoconstrictor effects with reduced cerebral perfusion pressure. As a consequence, intracranial pressure increases and neurocognitive impairments, delayed cerebral ischemia or brainstem herniation appear. Conclusions: The control of oxygenation and the excretion of carbon dioxide were crucial to maintain neuronal homeostasis, avoiding the decrease in cerebral perfusion pressure and the increase in intracranial pressure. It is suggested to avoid hypoxemia and hyperoxemia, limit or avoid hypercapnia, and use hypocapnic hyperventilation only in conditions of brainstem herniation.

Síndrome de infusión de propofol y COVID-19. Reporte de caso / Propofol and COVID-19 infusion syndrome. Case report

Resumen: La forma grave de neumonía por SARS-CoV-2 (COVID-19) cursa en la mayoría de los casos con un síndrome de dificultad respiratoria aguda (SDRA). Es necesario emplear sedación durante su ventilación mecánica, el propofol es el que más de utiliza por su farmacocinética y farmacodinamia. El propofol es un anestésico que se usa ampliamente en las unidades de cuidados intensivos. Su empleo puede provocar un efecto adverso poco frecuente, pero en extremo grave, conocido como síndrome por infusión de propofol (SIP), el cual se encuentra estrechamente asociado a la velocidad de infusión aunado a factores de riesgos propios del paciente. Se caracteriza principalmente por inestabilidad hemodinámica, acidosis láctica y por progresión a disfunción multiorgánica. Se presenta un caso de SIP en paciente con síndrome de dificultad respiratoria aguda (SDRA) secundario a SARS-CoV-2 que desarrolla esta complicación asociada a la sedación. Se discute fisiopatológica clínica y consideraciones que deberán tomarse en cuenta al momento de su utilización en infusión continua.

Abstract: The severe form of SARS-CoV-2 pneumonia (COVID-19) occurs in most cases with acute respiratory distress syndrome (ARDS), requiring the use of sedation during mechanical ventilation, with propofol being the most widely used for its pharmacokinetics and pharmacodynamics. Propofol is a widely used anesthetic in intensive care units (ICU). Its use can cause an infrequent but extremely serious adverse effect, known as propofol infusion syndrome (PRIS), which is closely associated with the speed of infusion coupled with risk factors specific to the patient, the clinical features of PRIS are hemodynamic instability, lactic acidosis and with progression to multi-organ dysfunction. We present a case of SIP in a patient with acute respiratory distress syndrome (ARDS) secondary to SARS-CoV-2 who develops this complication associated with sedation, discusses clinical pathophysiology and considerations that should be taken into account when using it in continuous infusion.

Pacientes críticos COVID-19. ¿Han variado el manejo y los resultados en la UCI tras un año de pandemia? Estudio multicéntrico, prospectivo, observacional / Critical patients COVID-19 has changed the management and outcomes in the ICU after 1 year of the pandemic? A multicenter, prospective, observational study

Objetivo: Comparar las características clínicas, los tratamientos y la evolución de los pacientes críticos con neumonía por COVID-19 atendidos en unidades de cuidados intensivos (UCI) tras un año de pandemia. Metodología: Estudio multicéntrico, prospectivo, en el que se incluyó pacientes críticos COVID-19 en 9 UCI del noroeste de España. Se compararon las características clínicas, los tratamientos y la evolución de pacientes ingresados en UCI durante los meses de marzo-abril de 2020 (periodo1) con pacientes ingresados en enero-febrero de 2021 (periodo2). Resultados: Se incluyeron 337 pacientes (98 en el periodo1 y 239 en el periodo2). En el periodo2 menos pacientes requirieron ventilación mecánica invasiva (VMI) (65% vs 84%, p<0,001), utilizándose con mayor frecuencia cánulas nasales de alto flujo (CNAF) (70% vs 7%, p<0,001), ventilación mecánica no invasiva (VMNI) (40% vs 14%, p<0,001), corticoides (100% vs 96%, p=0,007) y posición de decúbito prono tanto en pacientes despiertos (42% vs 28%, p=0,012) como en pacientes intubados (67% vs 54%, p=0,034). Los días de VMI, de estancia en UCI y hospitalaria fueron inferiores en el periodo2. La mortalidad fue similar en los dos periodos estudiados (16% vs 17%). Conclusiones: Tras un año de pandemia, observamos que en los pacientes ingresados en UCI se ha utilizado con mayor frecuencia CNAF, VMNI, uso del decúbito prono y corticoides, disminuyendo los pacientes en VMI, así como los tiempos de estancia en UCI y de estancia hospitalaria. La mortalidad ha sido similar en los dos periodos a estudio.(AU)

Objective: To compare the clinical characteristics, treatments, and evolution of critical patients with COVID-19 pneumonia treated in intensive care units (ICU) after one year of pandemic. Methodology: Multicenter, prospective study, which included critical COVID-19 patients in 9 ICUs in northwestern Spain. The clinical characteristics, treatments, and evolution of patients admitted to the ICU during the months of March-April 2020 (period1) were compared with patients admitted in January-February 2021 (period2). Results: 337 patients were included (98 in period1 and 239 in period2). In period2, fewer patients required invasive mechanical ventilation (IMV) (65% vs. 84%, P<.001), using high-flow nasal cannulas (CNAF) more frequently (70% vs. 7%, P<.001), ventilation non-invasive mechanical (NIMV) (40% vs. 14%, P<.001), corticosteroids (100% vs. 96%, P=.007) and prone position in both awake (42% vs. 28%, P=.012), and intubated patients (67% vs. 54%, P=.034). The days of IMV, ICU stay and hospital stay were lower in period2. Mortality was similar in the two periods studied (16% vs. 17%). Conclusions: After one year of pandemic, we observed that in patients admitted to the ICU, CNAF, NIMV, use of the prone position, and corticosteroids have been used more frequently, reducing the number of patients in IMV, and the length of stay in the ICU and hospital stay. Mortality was similar in the two study periods.(AU)

Ventilação protetora na síndrome do desconforto respiratório agudo causada pela COVID-19: o manejo do fisioterapeuta / Protective ventilation in acute respiratory distress syndrome caused by COVID-19: the management of the physiotherapist

Objetivos: conhecer o manejo do fisioterapeuta relacionado à ventilação protetora em pacientes com SDRA por COVID-19, listando as principais estratégias utilizadas e as barreiras encontradas para sua implementação. Métodos: estudo de campo transversal e descritivo, de caráter quantitativo, realizado no período de outubro de 2021 a abril de 2022, com fisioterapeutas de hospitais públicos e privados, na cidade de Fortaleza, que tivessem experiência com pacientes infectados pela COVID-19. Para coleta de dados, utilizou-se um formulário online viabilizado pela plataforma Google Forms. Os dados foram tabulados em planilha Microsoft Excel® 2010 e, posteriormente, transferido para o Statistical Package for the Social Sciences (SPSS®) 20.0, utilizando-se a estatística descritiva. Resultados: participaram 102 fisioterapeutas, 74,5% do gênero feminino. As principais estratégias de ventilação protetora citadas foram: volume corrente de 6 mL/Kg por peso predito, pressão de platô menor que 30 cmH2O e driving pressure menor que 15 cmH2O (93,1%), além da titulação de PEEP (68,6%) e posição prona (64,7%). Manter uma driving pressure menor que 15 cmH2O (57,8%) e discordância profissional (43,1%) foram as principais barreiras encontradas para realização da ventilação protetora. Conclusão: a ventilação protetora configura-se no uso de baixos volumes e pressões, titulação da PEEP e posição prona. A manutenção de driving pressure menor que 15 cmH2O e discordância entre os profissionais na tomada de decisão destacam-se como as principais barreiras.

In period 2, fewer patients required invasive mechanical ventilation (IMV) (65% vs 84%, p < 0.001), using high-flow nasal cannulas (CNAF) more frequently (70% vs 7%, p < 0.001), ventilation non-invasive mechanical (NIMV) (40% vs 14%, p < 0.001), corticosteroids (100% vs 96%, p = 0.007) and prone position in both awake (42% vs 28%, p = 0.012), and intubated patients (67% vs 54%, p = 0.034). The days of IMV, ICU stay and hospital stay were lower in period 2. Mortality was similar in the two periods studied (16% vs 17%). CONCLUSIONS: After 1 year of pandemic, we observed that in patients admitted to the ICU, CNAF, NIMV, use of the prone position, and corticosteroids have been used more frequently, reducing the number of patients in IMV, and the length of stay in the ICU and hospital stay. Mortality was similar in the two study periods.

Desenvolvimento de Competências Especializadas em Enfermagem na Área da Pessoa em Situação Crítica / Relatório de Estágio - Desenvolvimento de Competências Especializadas em Enfermagem na Área da Pessoa em Situação Crítica / Development of Specialised Competencies in Nursing in the Area of People in Critical Condition

O desenvolvimento da especialidade em Enfermagem Médica Cirúrgica na Área da Pessoa em Situação Critica compreende a aquisição de competências comuns e específicas inerentes à mesma. Os estágios realizados visam contribuir para a formação do enfermeiro especialista, fomentando a prática baseada na evidência na prestação de cuidados de enfermagem, quer pelo próprio quer pelos pares. Neste sentido foi desenvolvido uma investigação-ação no contexto de local de trabalho, na temática da pronação em doentes despertos com dificuldade respiratória. Os objetivos deste trabalho visam evidenciar as competências comuns e específicas adquiridas em Enfermagem Médico-Cirúrgica na Área da Pessoa em Situação Crítica e capacitar os enfermeiros, de um serviço de um hospital da região centro, para a tomada de decisão de pronar doentes com dificuldade respiratória. O trabalho desenvolvido tem cariz quantitativo, correlacional e prospetivo. A partir de uma revisão integrativa da literatura elaborou-se um questionário para avaliação do conhecimento dos enfermeiros sobre a técnica de pronar e um fluxograma sobre tomada de decisão. Após aplicação do fluxograma, como intervenção da técnica de pronar, constituíram-se dois grupos focais, um com enfermeiros especialistas e outro com enfermeiros generalistas. Na fase anterior à aplicação do fluxograma não se observaram a adoção de técnica de pronação. Após formação de pares observaram-se 14 casos com critérios de pronação, dos quais seis foram alvo deste posicionamento. A tomada de decisão foi efetuada por enfermeiros que frequentaram a formação (valor p <0,05), detentores de especialidade (valor p < 0,05). Conclusão: A formação de pares contribuiu para a tomada de decisão no ato de pronar doentes com dificuldade respiratória, sobretudo em enfermeiros especialistas. Abordagens complementares à formação poderão contribuir para uma maior capacitação dos enfermeiros, tais como a construção e divulgação de protocolo de tomada de decisão por meios eletrónicos e presencialmente junto dos profissionais.

The development of the specialty in Medical Surgical Nursing in the area of Critical Care includes the acquisition of common and specific skills inherent to it. The internships aim at contributing to the training of specialist nurses, fostering evidence-based practice in the provision of nursing care, both by the nurse him/herself and his/her peers. In this sense, an action-research study was conducted in the workplace on the topic of pronation in awake patients with respiratory distress. The objectives of this study aimed to identify the common and specific skills acquired in Medical-Surgical Nursing in the area of Critical Care and to empower nurses from a service of a hospital in the central region of Portugal to make the decision to pronate patients with respiratory distress. This study has a quantitative, correlational and prospective nature. Based on an integrative literature review, a questionnaire was designed to assess nurses' knowledge about the pronation technique and a flowchart on decision-making. Após aplicação do fluxograma, como intervenção da técnica de pronar, constituíram dois grupos focais, um com enfermeiros especialistas e outro com enfermeiros geraisistas. In the phase prior to the application of the flowchart, the adoption of the pronation technique was not observed. After pair formation, 14 cases with pronation criteria were observed, of which six were subject to this positioning. Decision-making was performed by nurses who had attended the training (p value <0.05) and who had a specialty (p value < 0.05). Conclusão: A formação de pares contribuiu para a tomada de decisão no ato de pronar doentes com dificuldade respiratória, sobretudo em enfermeiros especialistas. Complementary approaches to training may contribute to nurses' greater empowerment, such as the development and dissemination of a decision-making protocol through electronic and face-to-face means among professionals.

Relación de la presión de distensión pulmonar con la mortalidad en pacientes bajo ventilación mecánica con COVID-19 / Relationship of lung distention pressure with mortality in patients under mechanical ventilation with COVID-19 / Relação da pressão de distensão pulmonar com a mortalidade em pacientes sob ventilação mecânica com COVID-19

Resumen: Objetivo: Determinar la relación de la presión de distensión pulmonar (DP) con la mortalidad en pacientes bajo ventilación mecánica (VM) con COVID-19. Material y métodos: Estudio de cohorte en pacientes con COVID-19 y VM de marzo a septiembre de 2020, se compararon dos grupos, expuesto (pacientes con DP superior a 13 cmH2O) y no expuestos (pacientes con DP igual o menor a 13 cmH2O), se analizó la edad, sexo, hipertensión arterial (HTA), diabetes, obesidad, enfermedad renal crónica (ERC), enfermedad pulmonar obstructiva crónica (EPOC), inmunosupresión y enfermedad cardiovascular. Resultados: Con un total de 90 pacientes, la DP alta mostró ser un factor de riesgo para defunción (p = 0.000) al igual que la HTA (p = 0.013) y la inmunosupresión (p = 0.040). En pacientes hipertensos se encontró una DP de 10 cmH2O como meta de protección pulmonar, la cual se relaciona con la probabilidad de morir en 49.6% incrementando a 89.6% cuando existe una DP de 13 cmH2O. Conclusiones: Ochenta por ciento de la población tiene alto riesgo de mortalidad cuando existe DP alta, e incremento de mortalidad cuando se asocia con HTA e inmunosuprimidos. El resultado más importante fue la relación de mortalidad de la DP en pacientes hipertensos.

Abstract: Objective: To determine the relationship of driving pressure (DP) with mortality in patients under mechanical ventilation (MV) with COVID-19. Material and methods: Cohort study in patients with COVID-19 and MV from March to September 2020, two groups were compared, exposed (patients with DP greater than 13 cmH2O) and unexposed (patients with DP equal to or less than 13 cmH2O), age was analyzed, sex, hypertension (HT), diabetes, obesity, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), immunosuppression, and cardiovascular disease. Results: With a total of 90 patients, high DP was shown to be a risk factor for death (p = 0.000) as well as hypertension (p = 0.013) and immunosuppression (p = 0.040). In hypertensive patients, a DP of 10 cmH2O was found as a lung protection goal, which is related to the probability of dying in 49.6%, increasing to 89.6% when there is a DP of 13 cmH2O. Conclusions: 80% of the population has a high risk of mortality when there is high DP, and an increase in mortality when associated with hypertension and immunosuppression. The most important result was the mortality ratio of DP in hypertensive patients.

Resumo: Objetivo: Determinar a relação da pressão de distensão pulmonar (DP) com a mortalidade em pacientes com COVID-19 com ventilação mecânica (VM). Material e métodos: Estudo de coorte em pacientes com COVID-19 e VM de março a setembro de 2020, foram comparados dois grupos, expostos (pacientes com DP maior que 13 cmH2O) e não expostos (pacientes com DP igual ou menor que 13 cmH2O), analisou-se a idade, sexo, pressão arterial alta (HAS), diabetes, obesidade, DRC, DPOC, imunossupressão e doenças cardiovasculares. Resultados: Com um total de 90 pacientes, a DP elevada mostrou-se fator de risco para óbito (p = 0.000), assim como hipertensão (p = 0.013) e imunossupressão (p = 0.040). Em pacientes hipertensos, encontrou-se uma DP de 10 cmH2O como meta de proteção pulmonar, que está relacionada à probabilidade de morrer em 49.6%, aumentando para 89.6% quando há DP de 13 cmH2O. Conclusões: 80% da população tem alto risco de mortalidade quando há DP elevada, e mortalidade aumentada quando associada à hipertensão e imunossupressão. O resultado mais importante foi a razão de mortalidade da DP em pacientes hipertensos.

Quality of life and persistent symptoms after hospitalization for COVID-19. A prospective observational study comparing ICU with non-ICU patients.

BACKGROUND: Hospitalized COVID-19 patients are prone to develop persistent symptoms and to show reduced quality of life following hospital admission. METHODS: Prospective cohort study of COVID-19 patients admitted to a hospital from March 1 to April 30, 2020. The primary outcome was to compare health related quality of life and persistent symptoms six months after hospital admission, of COVID-19 patients who required ICU admission with those who did not. RESULTS: Among the 242 patients hospitalized during the defined period of time, 44 (18.2%) needed ICU admission. Forty (16.5%) patients died during hospital admission. Two hundred and two (83.5%) patients were discharged alive from the hospital. At six months, 183 (75.6%) patients completed the questionnaires (32 ICU patients and 151 non ICU patients). Ninety-six (52.4%) reported decreased quality of life and 143 (78.1%) described persistent symptoms. More ICU patients showed worsening of their quality of life (71.9% vs 43.7%, P=0.004). There were no differences in the proportion of patients with persistent symptoms between ICU and non ICU patients (87.5% vs 76.2%, P=0.159). ICU patients showed more frequently dyspnea on exertion (78.1% vs 47.7%, P=0.02), dyspnea on light exertion (37.5% vs 4.6%, P<0.001), and asthenia (56.3 vs 29.1, P=0.003). CONCLUSIONS: Survivors of COVID-19 needing hospitalization had persistent symptoms and a decline in the quality of life. ICU patients referred a large decrease of their quality of life compared with non ICU patients.

Calidad de vida y síntomas persistentes tras hospitalización por COVID-19. Estudio observacional prospectivo comparando pacientes con o sin ingreso en UCI / Quality of life and persistent symptoms after hospitalization for COVID-19. A prospective observational study comparing ICU with non-ICU patients

Antecedentes/contexto: Existe una tendencia en los pacientes hospitalizados por COVID-19 a desarrollar síntomas persistentes y a presentar una disminución en su calidad de vida tras el ingreso hospitalario. Métodos: Estudio de cohorte prospectivo de pacientes con COVID-19 con ingreso hospitalario entre el 1 de marzo al 30 de abril de 2020. El objetivo primario fue comparar la calidad de vida relacionada con la salud y la presencia de síntomas persistentes seis meses después del ingreso, comparando los pacientes que requirieron ingreso en UCI con los que no lo precisaron. Resultados: De los 242 pacientes hospitalizados durante el período de estudio, 44 (18,2%) necesitaron ingreso en UCI. Cuarenta (16,5%) pacientes fallecieron durante el ingreso hospitalario. Doscientos dos (83,5%) pacientes fueron dados de alta del hospital. A los seis meses, 183 (75,6%) pacientes completaron los cuestionarios (32 pacientes UCI y 151 pacientes no UCI). Noventa y seis (52,4%) refirieron disminución de la calidad de vida y 143 (78,1%) describieron síntomas persistentes. Un número mayor de pacientes de UCI mostraron un empeoramiento de su calidad de vida (71,9 vs. 43,7%, p = 0,004). No hubo diferencias en la proporción de pacientes con síntomas persistentes entre los pacientes con UCI y sin UCI (87,5 vs. 76,2%, p = 0,159). Los pacientes de UCI mostraron con mayor frecuencia disnea de esfuerzo (78,1 vs. 47,7%, p = 0,02), disnea de pequeños esfuerzos (37,5 vs. 4,6%, p < 0,001) y astenia (56,3 vs. 29,1%, p = 0,003). Conclusiones: Los supervivientes de COVID-19 que necesitaron hospitalización presentaron síntomas persistentes y un deterioro de su calidad de vida. Los pacientes de UCI refirieron una mayor disminución de su calidad de vida, en comparación con los pacientes que no precisaron UCI.(AU)

Recomendaciones para el manejo ventilatorio invasivo con ictus isquémico y COVID-19 / Recommendations for invasive ventilatory management witch ischemic stroke and COVID-19

Introducción: Las principales guías de tratamiento del ictus isquémico en el curso de la infección por COVID-19 no ofrecen sugerencias sobre el empleo de la ventilación mecánica artificial en estos pacientes. Objetivo: Describir elementos de interés sobre el uso de la ventilación mecánica artificial en pacientes con ictus isquémico y COVID-19. Método: Revisión narrativa de la literatura disponible en inglés y español en bases de datos como: PubMed, SciELO y Google académico. Se utilizaron los descriptores "COVID-19", "SARS-CoV-2", "neurological manifestations", "acute ischemic stroke", "acute brain injury", "mechanical ventilation", "respiratory failure", "ARDS", "neurocritical care", entre otros. Ante la escaza evidencia publicada los criterios expuestos se realizaron sobre la base de lo divulgado para pacientes con ictus isquémico y ventilación mecánica sin COVID-19. Resultados: El ictus isquémico en el curso de la infección por COVID-19 tiene una alta mortalidad. Se presenta fundamentalmente en la enfermedad más grave, mayormente en pacientes con síndrome de distrés respiratorio agudo. El uso de ventilación mecánica puede ser controversial debido al efecto de la misma sobre el cerebro. Conclusiones: Hasta la fecha no existen publicaciones sobre el manejo ventilatorio en este caso particular. Sobre la base de lo documentado en pacientes ventilados con ictus isquémico o daño cerebral agudo, la ventilación protectora puede ser usada con seguridad, así como el uso de maniobras de la posición prono. Siempre bajo estricta monitorización de la presión intracranealAU),

Introduction: The main guidelines for the treatment of ischemic stroke in the course of COVID-19 infection do not offer suggestions on the use of artificial mechanical ventilation in these patients. Objective: Describe elements of interest on the use of artificial mechanical ventilation in patients with ischemic stroke and COVID-19. Method: Narrative review of the literature available in English and Spanish in databases such as: PubMed, SciELO and Google scholar. The descriptors "COVID-19", "SARS-CoV-2", "neurological manifestations", "acute ischemic stroke", "acute brain injury", "mechanical ventilation", "respiratory failure", "ARDS", "neurocritical care", among others, were used. Given the scarce published evidence, the criteria presented were carried out on the basis of what was reported for patients with ischemic stroke and mechanical ventilation without COVID-19. Results: Ischemic stroke in the course of COVID-19 infection has a high mortality rate. It occurs mainly in the most severe stage of the disease, mostly in patients with acute respiratory distress syndrome. The use of mechanical ventilation can be controversial because of its effect on the brain. Conclusions: To date there are no publications on ventilatory management in this particular case. Based on what has been documented in ventilated patients with ischemic stroke or acute brain damage, protective ventilation can be used safely, as well as the use of prone position maneuvers, always under strict monitoring of intracranial pressure(AU)

SARS-CoV-2 en Pediatría: abordaje de la transmisión, fisiopatología ehipótesis de presentación clínica / Sars-cov-2 in pediatrics: transmission approach, pathophysiology and clinical presentation hypothesis

La pandemia de COVID-19 causada por el síndrome respiratorio agudo severo coronavirus 2 (SARS-CoV-2) es una infección producida por inhalación de gotas o contacto directo con superficies infectadas. Los síntomas clínicos son similares a cualquier infección viral respiratoria aguda; la enfermedad suele ser más leve en los niños. El objetivo fue describir el abordaje de la transmisión, la fisiopatología y las manifestaciones clínicas del SARS-CoV-2 en población pediátrica. Se realizó una revisión bibliográfica en bases de datos académicas PubMed, LILACS, OVID-MEDLINE usando términos DECS-LILACS, aplicando filtros de búsqueda y se seleccionaron textos científicos e información relevante para la investigación. Los resultados evidencian una menor incidencia, prevalencia, hospitalizaciones e ingreso a unidades de cuidados intensivos. Es necesario corroborar las hipótesis planteadas para fortalecer estos conocimientos y determinar las características que predominan en la lesión pulmonar por infección de SARS-CoV-2 en Pediatría.(UA)

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is an infection caused by inhalation of droplets or direct contact with infected surfaces. The clinical symptoms are similar to any acute respiratory viral infection; the disease is usually milder in children. The objective was to describe the transmission approach, pathophysiology and clinical manifestations of SARS-CoV-2 in the pediatric population. A bibliographic review was carried out in PubMed, LILACS, OVID-MEDLINE academic databases using DECS-LILACS terms, applying search filters and scientific texts and relevant information for the research were selected. The results show a lower incidence, prevalence, hospitalizations and admission to intensive care units. It is necessary to corroborate the hypotheses proposed to strengthen this knowledge and determine the characteristics that predominate in pulmonary injury due to SARS-CoV-2 infection in pediatrics.(AU)

Awake pronation with helmet continuous positive airway pressure for COVID-19 acute respiratory distress syndrome patients outside the ICU: A case series.

OBJECTIVE: Continuous positive airway pressure (CPAP) is an important therapeutic tool in COVID-19 acute respiratory distress syndrome (ARDS) since it improves oxygenation, reduces respiratory rate and can prevent intubation and intensive care unit (ICU) admission. CPAP during pronation has seldom been described and never during sedation. DESIGN: Case series. SETTING: High dependency unit of San Carlo University Hospital (Potenza, Italy). PATIENTS: Eleven consecutive patients with COVID-19 ARDS. INTERVENTION: Helmet CPAP in prone position after failing a CPAP trial in the supine position. MAIN VARIABLE OF INTEREST: Data collection at baseline and then after 24, 48 and 72h of pronation. We measured PaO2/FIO2, pH, lactate, PaCO2, SpO2, respiratory rate and the status of the patients at 28-day follow up. RESULTS: Patients were treated with helmet CPAP for a mean±SD of 7±2.7 days. Prone positioning was feasible in all patients, but in 7 of them dexmedetomidine improved comfort. PaO2/FIO2 improved from 107.5±20.8 before starting pronation to 244.4±106.2 after 72h (p<.001). We also observed a significantly increase in Sp02 from 90.6±2.3 to 96±3.1 (p<.001) and a decrease in respiratory rate from 27.6±4.3 to 20.1±4.7 (p=.004). No difference was observed in PaCO2 or pH. At 28 days two patients died after ICU admission, one was discharged in the main ward after ICU admission and eight were discharged home after being successfully managed outside the ICU. CONCLUSIONS: Helmet CPAP during pronation was feasible and safe in COVID-19 ARDS managed outside the ICU and sedation with dexmedetomidine safely improved comfort. We recorded an increase in PaO2/FIO2, SpO2 and a reduction in respiratory rate.
