RESUMO

BACKGROUND: Epidemiological data on patients with COVID-19 referred to specialized weaning centers (SWCs) are sparse, particularly in low- and middle-income countries. Our aim was to describe clinical features, epidemiology, and outcomes of subjects admitted to SWCs in Argentina. METHODS: We conducted a prospective, multi-center, observational study between July 2020-December 2021 in 12 SWCs. We collected demographic characteristics, laboratory results, pulmonary function, and dependence on mechanical ventilation at admission, decannulation, weaning from mechanical ventilation, and status at discharge. A multiple logistic model was built to predict home discharge. RESULTS: We enrolled 568 tracheostomized adult subjects after the acute COVID-19 phase who were transferred to SWCs. Age was 62 [52-71], males 70%, Charlson comorbidity index was 2 [0-3], and length of stay in ICU was 42 [32-56] d. Of the 315 ventilator-dependent subjects, 72.4% were weaned, 427 (75.2%) were decannulated, and 366 subjects (64.5%) were discharged home. The mortality rate was 6.0%. In multivariate analysis, age (odds ratio 0.30 [95% CI 0.16-0.56], P < .001), Charlson comorbidity index (odds ratio 0.43 [95% CI 0.22-0.84], P < .01), mechanical ventilation duration in ICU (odds ratio 0.80 [95% CI 0.72-0.89], P < .001), renal failure (odds ratio 0.40 [95% CI 0.22-0.73], P = .003), and expiratory muscle weakness (odds ratio 0.35 [95% CI 0.19-0.62], P < .001) were independently associated with home discharge. CONCLUSIONS: Most subjects with COVID-19 transferred to SWCs were weaned, achieved decannulation, and were discharged to home. Age, high-comorbidity burden, prolonged mechanical ventilation in ICU, renal failure at admission, and expiratory muscle weakness were inversely associated with home discharge.

RESUMO

During the COVID-19 pandemic, Latin American and Caribbean countries implemented stringent public health and social measures that disrupted economic and social activities. This study used an integrated model to evaluate the epidemiological, economic, and social trade-offs in Argentina, Brazil, Jamaica, and Mexico throughout 2021. Argentina and Mexico displayed a higher gross domestic product (GDP) loss and lower deaths per million compared with Brazil. The magnitude of the trade-offs differed across countries. Reducing GDP loss at the margin by 1 percent would have increased daily deaths by 0.5 per million in Argentina but only 0.3 per million in Brazil. We observed an increase in poverty rates related to the stringency of public health and social measures but no significant income-loss differences by sex. Our results indicate that the economic impact of COVID-19 was uneven across countries as a result of different pandemic trajectories, public health and social measures, and vaccination uptake, as well as socioeconomic differences and fiscal responses. Policy makers need to be informed about the trade-offs to make strategic decisions to save lives and livelihoods.

RESUMO

Antimicrobial resistance is a pressing global health concern, leading to 4.95 million deaths in 2019. We conducted a systematic review and meta-analysis to assess the lethality attributed to infections caused by multidrug-resistant organisms (MDROs) in Latin America and the Caribbean. A comprehensive search of major databases retrieved relevant studies from 2000-2022. We included 54 observational studies, primarily from Brazil, Argentina, and Colombia. The most commonly studied organism was methicillin-resistant Staphylococcus aureus. The overall unadjusted case fatality rate related to MDROs was 45.0%; higher adjusted lethality was observed in persons infected with MDROs than in those infected with other pathogens (adjusted odds ratio 1.93, 95% CI 1.58-2.37). A higher lethality rate was seen in patients who did not receive appropriate empirical treatment (odds ratio 2.27, 95% CI 1.44-3.56). These findings underscore the increased lethality associated with antimicrobial resistance in Latin America and the Caribbean.

RESUMO

OBJECTIVES: To describe the rate of failure of the first transition to pressure support ventilation (PSV) after systematic spontaneous awakening trials (SATs) in patients with acute hypoxemic respiratory failure (AHRF) and to assess whether the failure is higher in COVID-19 compared with AHRF of other etiologies. To determine predictors and potential association of failure with outcomes. DESIGN: Retrospective cohort study. SETTING: Twenty-eight-bedded medical-surgical ICU in a private hospital (Argentina). PATIENTS: Subjects with arterial pressure of oxygen (AHRF to Fio2 [Pao2/Fio2] < 300 mm Hg) of different etiologies under controlled mechanical ventilation (MV). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We collected data during controlled ventilation within 24 hours before SAT followed by the first PSV transition. Failure was defined as the need to return to fully controlled MV within 3 calendar days of PSV start. A total of 274 patients with AHRF (189 COVID-19 and 85 non-COVID-19) were included. The failure occurred in 120 of 274 subjects (43.7%) and was higher in COVID-19 versus non-COVID-19 (49.7% and 30.5%; p = 0.003). COVID-19 diagnosis (odds ratio [OR]: 2.22; 95% CI [1.15-4.43]; p = 0.020), previous neuromuscular blockers (OR: 2.16; 95% CI [1.15-4.11]; p = 0.017) and higher fentanyl dose (OR: 1.29; 95% CI [1.05-1.60]; p = 0.018) increased the failure chances. Higher BMI (OR: 0.95; 95% CI [0.91-0.99]; p = 0.029), Pao2/Fio2 (OR: 0.87; 95% CI [0.78-0.97]; p = 0.017), and pH (OR: 0.61; 95% CI [0.38-0.96]; p = 0.035) were protective. Failure groups had higher 60-day ventilator dependence (p < 0.001), MV duration (p < 0.0001), and ICU stay (p = 0.001). Patients who failed had higher mortality in COVID-19 group (p < 0.001) but not in the non-COVID-19 (p = 0.083). CONCLUSIONS: In patients with AHRF of different etiologies, the failure of the first PSV attempt was 43.7%, and at a higher rate in COVID-19. Independent risk factors included COVID-19 diagnosis, fentanyl dose, previous neuromuscular blockers, acidosis and hypoxemia preceding SAT, whereas higher BMI was protective. Failure was associated with worse outcomes.

RESUMO

BACKGROUND: Patients requiring mechanical ventilation due to COVID-19 have different characteristics of evolution and outcome compared to the general ICU population. Although early weaning from mechanical ventilation is associated with improved outcomes, inadequate identification of patients unable to be weaned may lead to extubation failure and increased days on mechanical ventilation. Outcomes related to mechanical ventilation weaning in this population are scare and inconclusive. Therefore, the objective of this study was to describe the characteristics of mechanical ventilation weaning in subjects with acute respiratory failure induced by COVID-19. METHODS: This was a multi-center, prospective cohort study. We included adult subjects requiring at least 12 h of mechanical ventilation due to COVID-19 infection admitted to any participating ICUs. Characteristics of the mechanical ventilation weaning and extubation process, as well as clinical results, were the primary outcome variables. Weaning types were defined according to previously described and internationally recognized categories. RESULTS: Three hundred twenty-six subjects from 8 ICUs were included. A spontaneous breathing trial (SBT) was not performed in 52.1% of subjects. One hundred twenty-eight subjects were extubated, and 29.7% required re-intubation. All the subjects included could be classified by Weaning according to a New Definition (WIND) classification (group 0 = 52.1%, group 1 = 28.5%, group 2 = 8.0%, and group 3 = 11.3%) with statistically significant differences in duration of mechanical ventilation (P < .001) and ICU length of stay (P < .001) between groups. CONCLUSIONS: The mechanical ventilation weaning process in subjects with COVID-19 was negatively affected by the disease, with many subjects never completing an SBT. Even though temporal variables were modified, the clinical outcomes in each weaning group were similar to those previously reported.

RESUMO

BACKGROUND: Oxygen therapy via high-flow nasal cannula generates physiologic changes that impact ventilatory variables of patients. However, we know that there are detrimental effects on airway mucosa related to inhalation of gases. The objective of this study was to evaluate the performance in terms of absolute humidity, relative humidity, and temperature of different brands of heated humidifiers and circuits in the invasive mode during the use of high-flow oxygen therapy in flows between 30 and 100 L/min. METHODS: A prospective observational study conducted at the Sanatorio Anchorena equipment analysis laboratory; September 5 to October 20, 2019. RESULTS: A statistically significant interaction was found among the programmed flows and the different combinations of devices and circuits for the delivery of absolute humidity (P < .001). An effect of flow on delivered absolute humidity was found, regardless of the equipment and circuit combination (P < .001). However, in the invasive mode, the combination of the Fisher&Paykel MR850 heated humidifier with the Medtronic-Dar circuit, the Intersurgical circuit, and the AquaVENT circuit always reached or achieved absolute humidity values > 33 mg/L, even at flows up to 100 L/min. The combination of the Flexicare FL9000 heated humidifier with the Fisher&Paykel RT202 circuit, the Fisher&Paykel Evaqua 2 circuit, the Flexicare circuit, the AquaVENT circuit, and the GGM circuit achieved similar results. The mean (SD) of absolute humidity delivered in the invasive mode (36.2 ± 5.9 mg/L) was higher compared with the noninvasive mode (26.8 ± 7.2 mg/L) (P < .001), regardless of circuit and programmed flows. CONCLUSIONS: When heated humidifiers were used in the invasive mode for high-flow oxygen therapy, absolute humidity depended not only on the heated humidifiers and the combination of circuits but also on the programmed flow, especially at flows > 50 L/min. Moreover, the heated humidifiers exhibited different behaviors, in some cases inefficient, in delivering adequate humidification. However, some equipment improved performance when set to the invasive mode.

RESUMO

OBJECTIVE: To compare gas exchange indices behavior by using liberal versus conservative oxygenation targets in patients with moderate to severe acute respiratory distress syndrome secondary to COVID-19 under invasive mechanical ventilation. We also assessed the influence of high FiO2 on respiratory system mechanics. METHODS: We prospectively included consecutive patients aged over 18 years old with a diagnosis of COVID-19 and moderate-severe acute respiratory distress syndrome. For each patient, we randomly applied two FiO2 protocols to achieve SpO2 88% - 92% or 96%. We assessed oxygenation indices and respiratory system mechanics. RESULTS: We enrolled 15 patients. All the oxygenation indices were significantly affected by the FiO2 strategy (p < 0.05) selected. The PaO2/FiO2 deteriorated, PA-aO2 increased and Pa/AO2 decreased significantly when using FiO2 to achieve SpO2 96%. Conversely, the functional shunt fraction was reduced. Respiratory mechanics were not affected by the FiO2 strategy. CONCLUSION: A strategy aimed at liberal oxygenation targets significantly deteriorated gas exchange indices, except for functional shunt, in COVID-19-related acute respiratory distress syndrome. The respiratory system mechanics were not altered by the FiO2 strategy.Clinical Trials Register: NCT04486729.


OBJETIVO: Comparar o comportamento dos índices de troca gasosa conforme o uso de alvos de oxigenação liberais em comparação a conservadores em pacientes com síndrome do desconforto respiratório agudo moderada a grave secundária à COVID-19 e em uso de ventilação mecânica; avaliar a influência da FiO2 elevada na mecânica do sistema respiratório. MÉTODOS: Foram incluídos prospectivamente pacientes consecutivos com idades acima de 18 anos, diagnóstico de COVID-19 e síndrome do desconforto respiratório agudo moderada e grave. Para cada paciente, aplicou-se aleatoriamente dois protocolos de FiO2 para obter SpO2 de 88% a 92% ou 96%. Avaliaram-se os índices de oxigenação e a mecânica do sistema respiratório. RESULTADOS: Foram incluídos 15 pacientes. Todos seus índices foram significantemente afetados pela estratégia de FiO2 (p < 0,05). A proporção PaO2/FiO2 deteriorou, o PA-aO2 aumentou e o Pa/AO2 diminuiu significantemente com a utilização de FiO2 para obter SpO2 96%. Opostamente, a fração de shunt funcional foi reduzida. A mecânica respiratória não foi afetada pela estratégia de FiO2. CONCLUSÃO: Uma estratégia com alvos liberais de oxigenação deteriorou significantemente os índices de troca gasosa, com exceção do shunt funcional, em pacientes com síndrome do desconforto respiratório agudo relacionada à COVID-19. A mecânica do sistema respiratório não foi alterada pela estratégia de FiO2.Registro Clinical Trials: NCT04486729.

RESUMO

RESUMO A respiração espontânea pode ser prejudicial para pacientes com pulmões previamente lesados, especialmente na vigência de síndrome do desconforto respiratório agudo. Mais ainda, a incapacidade de assumir a respiração totalmente espontânea durante a ventilação mecânica e a necessidade de voltar à ventilação mecânica controlada se associam com mortalidade mais alta. Existe uma lacuna no conhecimento em relação aos parâmetros que poderiam ser úteis para predizer o risco de lesão pulmonar autoinflingida pelo paciente e detecção da incapacidade de assumir a respiração espontânea. Relata-se o caso de um paciente com lesão pulmonar autoinflingida e as correspondentes variáveis, básicas e avançadas, de monitoramento da mecânica do sistema respiratório, além dos resultados fisiológicos e clínicos relacionados à respiração espontânea durante ventilação mecânica. O paciente era um homem caucasiano com 33 anos de idade e história clínica de AIDS, que apresentou síndrome do desconforto respiratório agudo e necessitou ser submetido à ventilação mecânica invasiva após falha do suporte ventilatório não invasivo. Durante os períodos de ventilação controlada, adotou-se estratégia de ventilação protetora, e o paciente mostrou evidente melhora, tanto do ponto de vista clínico quanto radiográfico. Contudo, durante cada período de respiração espontânea sob ventilação com pressão de suporte, apesar dos parâmetros iniciais adequados, das regulagens rigorosamente estabelecidas e do estrito monitoramento, o paciente desenvolveu hipoxemia progressiva e piora da mecânica do sistema respiratório, com deterioração radiográfica claramente correlacionada (lesão pulmonar autoinflingida pelo paciente). Após falha de três tentativas de respiração espontânea, o paciente faleceu por hipoxemia refratária no 29° dia. Neste caso, as variáveis básicas e avançadas convencionais não foram suficientes para identificar a aptidão para respirar espontaneamente ou predizer o risco de desenvolver lesão pulmonar autoinflingida pelo paciente durante a ventilação de suporte parcial.


ABSTRACT Spontaneous breathing can be deleterious in patients with previously injured lungs, especially in acute respiratory distress syndrome. Moreover, the failure to assume spontaneous breathing during mechanical ventilation and the need to switch back to controlled mechanical ventilation are associated with higher mortality. There is a gap of knowledge regarding which parameters might be useful to predict the risk of patient self-inflicted lung injury and to detect the inability to assume spontaneous breathing. We report a case of patient self-inflicted lung injury, the corresponding basic and advanced monitoring of the respiratory system mechanics and physiological and clinical results related to spontaneous breathing. The patient was a 33-year-old Caucasian man with a medical history of AIDS who developed acute respiratory distress syndrome and needed invasive mechanical ventilation after noninvasive ventilatory support failure. During the controlled ventilation periods, a protective ventilation strategy was adopted, and the patient showed clear clinical and radiographic improvement. However, during each spontaneous breathing period under pressure support ventilation, despite adequate initial parameters and a strictly adjusted ventilatory setting and monitoring, the patient developed progressive hypoxemia and worsening of respiratory system mechanics with a clearly correlated radiographic deterioration (patient self-inflicted lung injury). After failing three spontaneous breathing assumption trials, he died on day 29 due to refractory hypoxemia. Conventional basic and advanced monitoring variables in this case were not sufficient to identify the aptitude to breathe spontaneously or to predict the risk and development of patient self-inflicted lung injury during partial support ventilation.

RESUMO

OBJECTIVE: To describe the usual practice of mobility therapy in the adult intensive care unit for patients with and without COVID-19. METHODS: Online survey in which physical therapists working in an adult intensive care unit in Argentina participated. Sixteen multiple-choice or single-response questions grouped into three sections were asked. The first section addressed personal, professional and work environment data. The second section presented questions regarding usual care, and the third focused on practices under COVID-19 pandemic conditions. RESULTS: Of 351 physical therapists, 76.1% answer that they were exclusively responsible for patient mobility. The highest motor-based goal varied according to four patient scenarios: Mechanically ventilated patients, patients weaned from mechanical ventilation, patients who had never required mechanical ventilation, and patients with COVID-19 under mechanical ventilation. In the first and last scenarios, the highest goal was to optimize muscle strength, while for the other two, it was to perform activities of daily living. Finally, the greatest limitation in working with patients with COVID-19 was respiratory and/or contact isolation. CONCLUSION: Physical therapists in Argentina reported being responsible for the mobility of patients in the intensive care unit. The highest motor-based therapeutic goals for four classic scenarios in the closed area were limited by the need for mechanical ventilation. The greatest limitation when mobilizing patients with COVID-19 was respiratory and contact isolation.


OBJETIVO: Describir la práctica habitual de asistencia kinésica motora en la unidad de cuidados intensivos de adultos, tanto en pacientes con y sin COVID-19. MÉTODOS: Estudio observacional transversal de tipo encuesta online. Se incluyeron kinesiólogos que trabajan en unidades de cuidados intensivos de adultos en Argentina. Se realizaron 16 preguntas de respuesta múltiple o simple agrupadas en 3 apartados. El primero caracterizado por datos personales, profesionales o del ámbito laboral. El segundo, destinado a conocer el accionar habitual y un tercero enfocado en las prácticas bajo la pandemia COVID-19. RESULTADOS: Sobre 351 kinesiólogos, el 76.1% reportó que la movilización de los pacientes estaba a cargo exclusivamente de ellos. El objetivo máximo a alcanzar desde el aspecto motor fue variable según cuatro escenarios: Pacientes en ventilación mecánica, desvinculados de la ventilación mecánica, los que nunca estuvieron asociados a la ventilación mecánica y con COVID-19 en ventilación mecánica. En el primer y último escenario el objetivo máximo fue optimizar valores de fuerza muscular. En los restantes fue realizar actividades de la vida diaria. Por último, la mayor limitante en el abordaje de pacientes con COVID-19 fue el aislamiento respiratorio y/o de contacto. CONCLUSIÓN: Los kinesiólogos en Argentina reportaron encargarse de la movilización de los pacientes en la unidad de cuidados intensivos. Los objetivos máximos desde el aspecto motor para cuatro escenarios clásicos en el área cerrada podrían estar determinado por la asociación con la ventilación mecánica. La mayor limitación a la hora de movilizar a pacientes con COVID-19 fue el aislamiento respiratorio y de contacto.

Contudo, durante cada período de respiração espontânea sob ventilação com pressão de suporte, apesar dos parâmetros iniciais adequados, das regulagens rigorosamente estabelecidas e do estrito monitoramento, o paciente desenvolveu hipoxemia progressiva e piora da mecânica do sistema respiratório, com deterioração radiográfica claramente correlacionada (lesão pulmonar autoinflingida pelo paciente). Após falha de três tentativas de respiração espontânea, o paciente faleceu por hipoxemia refratária no 29° dia. Neste caso, as variáveis básicas e avançadas convencionais não foram suficientes para identificar a aptidão para respirar espontaneamente ou predizer o risco de desenvolver lesão pulmonar autoinflingida pelo paciente durante a ventilação de suporte parcial.

RESUMO

Instrumentation of the airways in critical patients (endotracheal tube or tracheostomy cannula) prevents them from performing their function of humidify and heating the inhaled gas. In addition, the administration of cold and dry medical gases and the high flows that patients experience during invasive and non-invasive mechanical ventilation generate an even worse condition. For this reason, a device for gas conditioning is needed, even in short-term treatments, to avoid potential damage to the structure and function of the respiratory epithelium. In the field of intensive therapy, the use of heat and moisture exchangers is common for this purpose, as is the use of active humidification systems. Acquiring knowledge about technical specifications and the advantages and disadvantages of each device is needed for proper use since the conditioning of inspired gases is a key intervention in patients with artificial airway and has become routine care. Incorrect selection or inappropriate configuration of a device can have a negative impact on clinical outcomes. The members of the Capítulo de Kinesiología Intensivista of the Sociedad Argentina de Terapia Intensiva conducted a narrative review aiming to show the available evidence regarding conditioning of inhaled gas in patients with artificial airways, going into detail on concepts related to the working principles of each one.

RESUMO

RESUMEN La instrumentación de la vía aérea del paciente crítico (tubo endotraqueal o cánula de traqueostomía) impide que ésta pueda cumplir con su función de calentar y humidificar el gas inhalado. Sumado a ello la administración de gases medicinales fríos y secos, y los altos flujos a los que se someten los pacientes en ventilación mecánica invasiva o no invasiva, generan una condición aún más desfavorable. Debido a esto es imperativo utilizar algún dispositivo para acondicionar los gases entregados incluso en tratamientos de corta duración con el fin de evitar los daños potenciales sobre la estructura y función del epitelio respiratorio. En el ámbito de terapia intensiva es habitual para esto el uso de intercambiadores de calor y humedad, como así también el uso de sistemas de humidificación activa. Para su correcta utilización es necesario poseer el conocimiento necesario sobre las especificaciones técnicas, ventajas y desventajas de cada uno de estos dispositivos ya que el acondicionamiento de los gases inspirados representa una intervención clave en pacientes con vía aérea artificial y se ha transformado en un cuidado estándar. La selección incorrecta del dispositivo o la configuración inapropiada pueden impactar negativamente en los resultados clínicos. Los integrantes del Capítulo de Kinesiología Intensivista de la Sociedad Argentina de Terapia Intensiva realizaron una revisión narrativa con el objetivo de exponer la evidencia disponible en relación al acondicionamiento del gas inhalado en pacientes con vía aérea artificial, profundizando sobre los conceptos relacionados a los principios de funcionamiento de cada uno.

RESUMO

Los angiomiolipomas renales son formaciones renales que se presentan de forma aislada o asociadas con otras patologías como esclerosis tuberosa o enfermedad de Von Hippel Lindau. Los angiomiolipomas renales se pueden presentar clínicamente con un shock hipovolémico por lesión de uno de sus vasos o con dolor abdominal por efecto masa debido a su tamaño. La resolución de los angiomiolipomas puede ser de manera programada o de urgencia, siendo las vías elegidas la nefrectomía parcial o la embolización arterial selectiva, dependiendo siempre de los recursos que se tengan y la experiencia del equipo quirúrgico.


Renal angiomyolipomas are kidney formations presented in isolation or associated with other diseases such as tuberous sclerosis or Von Hippel Lindau disease. Renal angiomyolipoma may present clinically with hypovolemic shock due to injury of one of its vessels or with abdominal pain due to mass effect because of its size. Angiomyolipomas can be resolved on scheduled basis or emergency, where the chosen ways are partial nephrectomy or selective arterial embolization, always depending on the resources you count on and the experience of the surgical team.
