RESUMO

Ventilator-associated pneumonia (VAP) is one of the most common causes of nosocomial infections. The aim of this study was to evaluate the antimicrobial and anti-biofilm activity of an in-house low-cost tracheostomy tube impregnated with chlorhexidine and violet crystal. The impregnated tracheostomy tubes demonstrated antimicrobial activity, including for multidrug-resistant bacteria. Fourteen patients were evaluated. During ventilation, VAP occurred in one patient in the coated group and in three patients in the control group (p=0.28). A reduction of biofilm cells was observed. This study provides preliminary evidence to support that the antiseptic impregnation of a tracheostomy tube provides significant antimicrobial activity.

RESUMO

Introducción: En diciembre de 2019, se detectó un brote de enfermedad por un nuevo coronavirus que evolucionó en pandemia con severa morbilidad respiratoria y mortali- dad. Los sistemas sanitarios debieron enfrentar una cantidad inesperada de pacientes con insuficiencia respiratoria. En Argentina, las medidas de cuarentena y control sani - tario retrasaron el primer pico de la pandemia y ofrecieron tiempo para preparar el sis- tema de salud con infraestructura, personal y protocolos basados en la mejor evidencia disponible en el momento. En una institución de tercer nivel de Neuquén, Argentina, se desarrolló un protocolo de atención para enfrentar la pandemia adaptado con la evo- lución de la mejor evidencia y evaluaciones periódicas de la mortalidad hospitalaria. Métodos: Estudio de cohorte observacional para evaluar la evolución de pacientes con COVID-19 con los protocolos asistenciales por la mortalidad hospitalaria global y al día 28 en la Clínica Pasteur de Neuquén en 2020. Resultados: Este informe describe los 501 pacientes diagnosticados hasta el 31 de di- ciembre de 2020. La mortalidad general fue del 16,6% (83/501) y del 12,2% (61/501) al día 28 de admisión. En los 139 (27,7%) pacientes con ventilación mecánica, la mortali- dad general y a los 28 días fue de 37,4% (52/139) y 28,1% (38/139) fallecieron, respec- tivamente. Los factores de riesgo identificados fueron edad, comorbilidades y altos re- querimientos de oxígeno al ingreso. Conclusión: La mortalidad observada en los pacientes hospitalizados en nuestra insti- tución en la primera ola de la pandemia COVID-19 fue similar a los informes internacio- nales y menor que la publicada en Argentina para el mismo período.

Introduction: In December 2019, an outbreak of disease due to a new coronavirus was detected that evolved into a pandemic with severe respiratory morbidity and mortality. Health systems had to face an unexpected number of patients with respiratory failure. In Argentina, quarantine and health control measures delayed the first peak of the pan - demic and offered time to prepare the health system with infrastructure, personnel and protocols based on the best evidence available at the time. In a third level institution of Neuquén, Argentina, a care protocol was developed to confront the pandemic adapted by evolving best evidence and periodic evaluations of hospital mortality. Methods: Observational cohort study to evaluate the evolution of patients hospitalized for COVID-19 with care protocols in terms of overall hospital mortality and at day 28 at the Pasteur Clinic in Neuquén in 2020. Results: This report describes the 501 patients diagnosed until December 31, 2020. Mortality was 16.6% (83/501) and 12.2% (61/501) on day 28 of admission. Among the 139 (27.7%) patients with mechanical ventilation, overall mortality and at 28 days it was 37.4% (52/139) and 28.1% (38/139), respectively. The risk factors identified were age, comorbidities and high oxygen requirements on admission. Conclusion: The mortality observed in patients hospitalized in our institution during the first wave of COVID-19 pandemic was similar to international reports and lower than other publications in Argentina for the same period.

RESUMO

La atrofia muscular espinal (AME) 5q es una de las enfermedades neuromusculares de mayor incidencia en la infancia. Sin embargo, la prevalencia de AME tipo 1, su forma más severa de presentación, es menor debido a muertes prematuras evitables antes de los dos años por insuficiencia ventilatoria subtratada. La irrupción de nuevos tratamientos modificadores de la enfermedad pueden cambiar dramáticamente este pronóstico y es una oportunidad para actualizar el manejo respiratorio, a través de cuidados estandarizados básicos, preferentemente no invasivos, abordando la debilidad de los músculos respiratorios, la insuficiencia tusígena y ventilatoria, con un enfoque preventivo. La siguiente revisión literaria entrega estrategias para evitar la intubación y la traqueostomía usando soporte ventilatorio no invasivo (SVN), reclutamiento de volumen pulmonar (RVP) y facilitación de la tos. Se analizan en detalle los protocolos de extubación en niños con AME tipo 1.

Spinal muscular atrophy (SMA) 5q is one of the neuromuscular diseases with the highest incidence in childhood. Nevertheless, the prevalence of its most severe form SMA1 is lower due to premature preventable deaths before two years of age related to ventilatory insufficiency undertreated. The emergence of new disease-modifying treatments can dramatically change this prognosis and is an opportunity to update respiratory management, through basic standardized care, mostly non-invasive, addressing respiratory muscles pump weakness, cough and ventilatory insufficiency with a preventive approach. This literature review provides consensus recommendations for strategies to avoid intubation and tracheostomy using noninvasive ventilatory support (NVS), lung volume recruitment (LVR), and cough facilitation. Extubation protocols in children with SMA type 1 are analyzed in detail.

RESUMO

Introducción: El edema agudo del pulmón es una enfermedad frecuente en los pacientes que se presentan en los servicios de urgencias. Objetivo: Caracterizar a los pacientes con edema agudo del pulmón en el servicio de urgencias. Método: Se realizó un estudio descriptivo y transversal en 37 pacientes con edema agudo del pulmón, que asistieron al cuerpo de guardia del Hospital Clinicoquirúrgico Docente Dr. Joaquín Castillo Duany de Santiago de Cuba, desde enero a noviembre de 2019. Las variables estudiadas fueron edad, sexo, estado al egreso y uso de la ventilación no invasiva. Resultados: No hubo diferencias entre ambos sexos, predominaron los mayores de 60 años, que padecían de hipertensión arterial. Se comprobó el poco uso de la ventilación no invasiva o invasiva. Conclusiones: El edema agudo del pulmón es más frecuente en pacientes mayores de 60 años, sin distinción de sexo. La mayoría lo presenta relacionado con la hipertensión arterial y existe un escaso uso de la ventilación no invasiva en estos casos.

Introduction: Acute pulmonary edema is a frequent disease among patients in emergency services. Objective: To characterize patients with acute pulmonary edema who attended the emergency services. Methods: A descriptive and cross-sectional study of 37 patients with acute pulmonary edema who attended the emergency services of Dr. Joaquín Castillo Duany Teaching Clinical Surgical Hospital in Santiago de Cuba was carried out, from January to November 2019. The studied variables were age, sex, alive or dead when discharged, noninvasive ventilation usage. Results: There were no differences between the sexes; there was a prevalence of patients older than 60 years of age, who suffered from hypertension. It was demonstrated low noninvasive or invasive ventilation usage. Conclusions: Acute pulmonary edema is more frequent among patients older than 60 years of age in both sexes. Most of the patients suffered from hypertension and there was a deficit in the implementation of noninvasive ventilation in these cases.

RESUMO

OBJECTIVE: To analyze the presence of frailty in survivors of severe COVID-19 admitted in the Intensive Care Unit (ICU) and followed six months after discharge. DESIGN: An observational, prospective and multicenter, nation-wide study. SETTING: Eight adult ICU across eight academic acute care hospitals in Mexico. PATIENTS: All consecutive adult COVID-19 patients admitted in the ICU with acute respiratory failure between March 8, 2020 to February 28, 2021 were included. Frailty was defined according to the FRAIL scale, and was obtained at ICU admission and 6-month after hospital discharge. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: The primary endpoint was the frailty status 6-months after discharge. A regression model was used to evaluate the predictors during ICU stay associated with frailty. RESULTS: 196 ICU survivors were evaluated for basal frailty at ICU admission and were included in this analysis. After 6-months from discharge, 164 patients were evaluated for frailty: 40 patients (20.4%) were classified as non-frail, 67 patients (34.2%) as pre-frail and 57 patients (29.1%) as frail. After adjustment, the need of invasive mechanical ventilation was the only factor independently associated with frailty at 6 month follow-up (Odds Ratio [OR] 3.70, 95% confidence interval 1.40-9.81, P = .008). CONCLUSIONS: Deterioration of frailty was reported frequently among ICU survivors with severe COVID-19 at 6-months. The need of invasive mechanical ventilation in ICU survivors was the only predictor independently associated with frailty.

RESUMO

La tasa de reintubación orotraqueal luego de la extubación se registra entre un 10 a 20%. La aplicación de soportes respiratorios no-invasivos (SRNI) posterior a la extuba-ción como cánula nasal de alto-flujo, ventilación no invasiva (dos niveles de presión) y presión positiva continua en la vía aérea demostraron ser seguras y efectivas post ex-tubación. El período pre-destete representa un momento crucial en el manejo de los pa-cientes críticos ya que el fracaso de la extubación, definido como la necesidad de reintu-bación dentro de los 2 a 7 días, demostró peores resultados al aumentar la mortalidad entre un 25-50%. Esta situación conlleva al requerimiento de ventilación mecánica prolongada, neumonía asociada a la ventilación mecánica y estancias prolongadas de internación. Por lo tanto, es esencial identificar a los pacientes que se beneficiarán utilizando SRNI post extubación.

The rate of re-intubation after extubation is recorded at 10-20%. The use of non-invasive respiratory support (NIRS) post-extubation such as high-flow nasal cannula, non-invasive ventilation (bilevel pressure) and continuous positive airway pressure (CPAP) have been shown to be safe and effective post-extubation. The pre-weaning period represents a crucial time in the management of critically ill patients, as extubation failure, defined as the need for reintubation within 2-7 days, showed worse outcomes with mortality increasing by 25-50%. This situation leads to the requirement for prolonged mechanical ventilation, ventilator-associated pneumonia and long lengths of hospital stay. Therefore, it is essential to identify patients who will benefit from NIRS post extubation.

RESUMO

Respiratory physiotherapy, including the management of invasive mechanical ventilation (MV) and noninvasive mechanical ventilation (NIV), is a key supportive intervention for critically ill patients. MV has potential for inducing ventilator-induced lung injury (VILI) as well as long-term complications related to prolonged bed rest, such as post-intensive care syndrome and intensive care unit acquired weakness. Physical and respiratory therapy, developed by the critical care team, in a timely manner, has been shown to prevent these complications. In this pathway, real-time bedside monitoring of changes in pulmonary aeration and alveolar gas distribution associated with postural positioning, respiratory physiotherapy techniques and changes in MV strategies can be crucial in guiding these procedures, providing safe therapy and prevention of potential harm to the patient. Along this path, electrical impedance tomography (EIT) has emerged as a new key non-invasive bedside strategy free of radiation, to allow visualization of lung recruitment. This review article presents the main and potential applications of EIT in relation to physiotherapy techniques in the ICU setting.
