The benefits of non-invasive ventilation for Community-Acquired Pneumonia: A meta-analysis

Non-Invasive Ventilation for Community-Acquired Pneumonia: Outcomes and Predictors of Failure from an ICU Cohort

Background and Objectives: The use of non-invasive ventilation (NIV) for community-acquired pneumonia (CAP) remains controversial. NIV failure in the setting of acute hypoxemic respiratory failure is associated with increased mortality, highlighting the need for careful patient selection. Methods and Methods: This is a retrospective observational cohort study. We included 140 patients with severe CAP, treated with either NIV or invasive mechanical ventilation (IMV) as their primary oxygenation strategy. Results: The median PaO2/FiO2 ratio and SOFA score upon ICU admission were 151 mmHg and 6, respectively. We managed 76% of patients with NIV initially and report an NIV success rate of 59%. Overall, the 28-day mortality was 25%, whilst for patients with NIV success, the mortality was significantly lower at 13%. In the univariate analysis, NIV failure was associated with the SOFA score (OR 1.33), the HACOR score (OR 1.14) and the presence of septic shock (OR 3.99). The SOFA score has an AUC of 0.75 for NIV failure upon ICU admission, whilst HACOR has an AUC of 0.76 after 2 h of NIV. Conclusions: Our results suggest that a SOFA ≤ 4 and an HACOR ≤ 5 are reasonable thresholds to identify patients with severe CAP likely to benefit from NIV.

Principio de proporcionalidad terapéutica en la decisión de intubación orotraqueal y ventilación mecánica invasiva en paciente COVID-19 grave

En medicina cuando se aplica el principio de proporcionalidad terapéutica se valoran los medios empleados y el fin previsible en cada paciente. Y se distingue entre tratamientos proporcionados o desproporcionados, valorando el beneficio y utilidad. Entre ellos su aplicación en el paciente COVID-19 grave que requiere intubación orotraqueal y ventilación mecánica invasiva. En ocasiones nos puede generar el dilema ético de proceder a realizar dicho procedimiento y no encontrar beneficio alguno, sino al contrario generar sufrimiento, dolor y prolongación de su posible agonía. Teniendo el deber ético en estos casos de no abandonar sino acompañar a través de los cuidados paliativos, siempre informando al familiar sobre la decisión que se tome. El analizar este principio de proporcionalidad terapéutica y su aplicación en las unidades de cuidado intensivo requiere de una conciencia moral por parte del grupo que tiene la responsabilidad de la toma de la decisiòn y dirimir el dilema ético que se presente. Recordando que a los pacientes que requieran intubación orotraqueal se les deben ofrecer todas las medidas requeridas en ventilación mecánica invasiva y no invasiva para mejoría de la hipoxemia.

Se presenta un análisis y reflexión sobre el principio de proporcionalidad terapéutica y su fundamentación ética al igual que una revisión sistemática de la literatura médica relacionada con pacientes con COVID-19 en insuficiencia respiratoria aguda. Y se establecen unas consideraciones científicas y éticas a tener en cuenta en el paciente COVID-19. El principio de proporcionalidad terapéutica ante la decisión de intubación orotraqueal debe fundamentarse en un juicio de proporcionalidad, que garantice que se han hecho y utilizado todos los medios previsibles para evitar la intubación orotraqueal y como único fin útil para beneficiar al paciente será la ventilación mecánica invasiva.

[Management of Adult Community-Acquired Pneumonia and Prevention - Update 2021 - Guideline of the German Respiratory Society (DGP), the Paul-Ehrlich-Society for Chemotherapy (PEG), the German Society for Infectious Diseases (DGI), the German Society of Medical Intensive Care and Emergency Medicine (DGIIN), the German Viological Society (DGV), the Competence Network CAPNETZ, the German College of General Practitioneers and Family Physicians (DEGAM), the German Society for Geriatric Medicine (DGG), the German Palliative Society (DGP), the Austrian Society of Pneumology Society (ÖGP), the Austrian Society for Infectious and Tropical Diseases (ÖGIT), the Swiss Respiratory Society (SGP) and the Swiss Society for Infectious Diseases Society (SSI)]

The present guideline provides a new and updated concept of the management of adult patients with community-acquired pneumonia. It replaces the previous guideline dating from 2016.The guideline was worked out and agreed on following the standards of methodology of a S3-guideline. This includes a systematic literature search and grading, a structured discussion of recommendations supported by the literature as well as the declaration and assessment of potential conflicts of interests.The guideline has a focus on specific clinical circumstances, an update on severity assessment, and includes recommendations for an individualized selection of antimicrobial treatment.The recommendations aim at the same time at a structured assessment of risk for adverse outcome as well as an early determination of treatment goals in order to reduce mortality in patients with curative treatment goal and to provide palliation for patients with treatment restrictions.
