ABSTRACT

Resumen El trasplante de pulmón bilateral es el tratamiento de las enfermedades pulmonares en su etapa terminal. Sin embargo, a veces se realiza el trasplante de un solo pulmón. La técnica no está exenta de complicaciones como la hiperinsuflación aguda del pulmón nativo y cambios en el diafragma, predisponiendo a atelectasias e insuficiencia respiratoria que pueden derivar en resul tados negativos. Por lo tanto, las pruebas de respiración espontánea pueden fallar y retrasar el proceso de des vinculación de la ventilación mecánica. La combinación de herramientas de monitorización avanzadas, como la tomografía por impedancia eléctrica y la ecografía, para diagnosticar la causa de este fallo, reconociendo y cuantificando la distribución del volumen pulmonar y su comportamiento dinámico, podría ser crucial para mejorar los resultados. Presentamos el caso de un paciente con trasplante unipulmonar y ventilación prolongada que falla en repetidas ocasiones durante la desvinculación de la ventilación mecánica, donde utilizamos herramientas de monitoreo avanzado para detectar la causa de la falla.


Abstract Bilateral lung transplantation is the treatment of end-stage lung diseases. However, sometimes a single lung transplant is performed. The technique is not exempt from complications such as acute hyperinfla tion of the native lung and changes in the diaphragm, predisposing to atelectasis and respiratory failure that can lead to negative results. Therefore, spontaneous breathing trials may fail and delay the weaning process. The combination of advanced monitoring tools, such as electrical impedance tomography and ultrasonography, to diagnose the cause of this failure, recognizing and quantifying the distribution of lung volume and its dynamic behavior could be crucial to improve outcomes. We present the case of a patient with a one-lung transplant and prolonged mechanical ventilation who, after presenting successive failures in the weaning pro cess, underwent advanced monitoring in order to find the causes of the failure.

ABSTRACT

RESUMO Objetivo: Descrever o conhecimento de profissionais de saúde relacionado com doação de pulmão e manejo do doador. Métodos: Realizou-se estudo descritivo, transversal, com base em levantamento anônimo conduzido entre março e setembro de 2019 envolvendo profissionais de saúde registrados na Sociedad Argentina de Terapia Intensiva. Resultados: Dentre os 736 participantes, a média de idade foi de 30,5 anos (desvio-padrão de 8,9), sendo 61,3% do sexo feminino. Dentre os participantes, 60% eram médicos, 21,5% enfermeiros e 17,9% fisioterapeutas. Dentre os participantes, 68% se consideravam adequadamente informados com relação à procura de órgãos, e 79,8% afirmaram estar cientes do manejo de um potencial doador sob terapia intensiva. Os critérios relativos a um doador de pulmão foram respondidos corretamente por 71,3% dos participantes. Entretanto, após a morte cerebral do doador, 51% dos participantes não fariam modificações nos parâmetros de ventilação mecânica, 22,9% não sabiam quais parâmetros reprogramar, e 44,5% escolheriam um volume corrente de 6 - 8mL/kg e pressão positiva expiratória final de 5cmH2O. Para 85% dos profissionais de saúde, o tipo de teste de apneia escolhido foi desconexão do ventilador, e apenas 18,5% utilizariam um protocolo de controle. As intervenções mais frequentemente utilizadas no caso de pressão parcial de oxigênio/fração inspirada de oxigênio < 300 foram titulação da pressão positiva expiratória final, aspiração traqueal em circuito fechado e manobras de recrutamento. Conclusão: Os profissionais de saúde que participaram deste levantamento na Argentina responderam corretamente à maior parte das questões relacionadas aos critérios para o doador de pulmão. Contudo, faltou-lhes um conhecimento detalhado relativo aos parâmetros ventilatórios, às estratégias ventilatórias e aos protocolos para doadores de pulmão. Programas educacionais são fundamentais para otimizar a doação de múltiplos órgãos e devem focalizar a proteção dos pulmões do doador, com objetivo de incrementar o número de órgãos disponíveis para transplante.


ABSTRACT Objective: To describe health care providers' knowledge about lung donation and donor lung management. Methods: A descriptive, cross-sectional study based on an anonymous survey was conducted between March and September 2018 among health care professionals registered to Sociedad Argentina de Terapia Intensiva. Results: Of the 736 respondents, the mean age was 40.5 years (standard deviation 8.9), and 61.3% were female. Sixty percent were physicians, 21.5% were nurses, and 17.9% were physiotherapists. Seventy-eight percent considered themselves appropriately informed about organ procurement, and 79.8% stated that they knew potential organ donor critical care management. The lung donor criteria were answered correctly by 71.3% of the respondents. However, after the donor's brain death, 51% made no changes to ventilator parameters, 22.9% were not aware of which parameters to reprogram, and 44.5% selected tidal volume of 6 - 8mL/kg and positive end expiratory pressure of 5cmH2O. For 85% of the health care providers, the type of apnea test chosen was disconnection from the ventilator, and only 18.5% used a lung management protocol. The most frequent interventions used in the case of arterial oxygen partial pressure/fractional inspired oxygen < 300 were positive end expiratory pressure titration, closed-circuit endotracheal suctioning, and recruitment maneuvers. Conclusion: Health care professionals surveyed in Argentina correctly answered most of the questions related to lung donor criteria. However, they lacked detailed knowledge about ventilatory settings, ventilatory strategies, and protocols for lung donors. Educational programs are key to optimizing multiorgan donation and should be focused on protecting the donor lungs to increase the numbers of organs available for transplantation.

ABSTRACT

RESUMEN Objetivo: Describir los resultados de la implementación de un protocolo de cuidados respiratorios y de ventilación mecánica en el potencial donante de pulmón, que cumplen las condiciones para ser procurados. El objetivo secundario es comparar los resultados con datos históricos. Métodos: Estudio retrospectivo y observacional. Incluye potenciales donantes aptos para procuración de órganos con muerte encefálica internados en las áreas críticas de la Ciudad Autónoma de Buenos Aires, desde abril de 2017 hasta marzo de 2018. Variables principales: número de potencial donante de pulmón que alcanzan el objetivo de procuración, tasa de pulmones procurados y tasa de pulmones implantados. Se consideraron valores significativos p < 0,05. Resultados: Se incluyeron 30 potenciales donantes de pulmón, 23 (88.5%; IC95% 69,8 - 97,6) cumplieron el objetivo de oxigenación. Veinte potenciales donantes de pulmón donaron órganos y de ellos, ocho donaron pulmones, con los cuales se realizaron 4 trasplantes bipulmonares y 8 unipulmonares. Los pulmones procurados e implantados en el periodo pre-protocolo fueron 7, mientras que durante el protocolo fueron 12 (valor p = 0,38). La tasa de implantación fue 58,3% (7/12) en el control histórico y 100% (12/12) (valor p = 0,04) en el periodo de estudio. Conclusión: El protocolo permitió alcanzar el objetivo de oxigenación en la mayoría de los potenciales donantes de pulmón y una mejoría estadísticamente significativa en la tasa de implantación.


ABSTRACT Objective: To describe the results from the implementation of a respiratory care and mechanical ventilation protocol on potential lung donors who met the conditions for procurement. The secondary objective is to compare the results with historical data. Methods: This was a retrospective, observational study. It included potential donors suitable for procurement of organs who had brain death and were hospitalized in critical care units of the Autonomous City of Buenos Aires from April 2017 to March 2018. Main variables: number of potential lung donors that reached the objective of procurement, rate of lungs procured, and rate of implanted lungs. Values of p < 0.05 were considered significant. Results: Thirty potential lung donors were included, and 23 (88.5%; 95%CI 69.8 - 97.6) met the oxygenation objective. Twenty potential lung donors donated organs, of whom eight donated lungs, with which four double lung transplants and eight single lung transplants were performed. Seven of 12 lungs were procured and implanted in the preprotocol period, while all 12 were under the protocol (p = 0.38). The implantation rate was 58.3% (7/12) in the historical control period and 100% (12/12) (p = 0.04) in the study period.

ABSTRACT

Objetivo: Describir los cambios observados en la frecuencia respiratoria, la frecuencia cardiaca y la puntuación de disnea antes y después de la utilización de un dispositivo alternativo de cánula nasal de alto flujo en pacientes con falla respiratoria aguda hipoxémica en una central de emergencias. Materiales y método: Estudio cuasi experimental y retrospectivo con pacientes adultos que acudieron a la central de emergencias con signos clínicos de falla respiratoria aguda hipoxémica. Los datos de frecuencia respiratoria, frecuencia cardíaca y la puntuación de disnea se recolectaron de la historia clínica electrónica antes y después de dos horas de haber utilizado un dispositivo Venturi conectado a un sistema de cánula nasal de alto flujo. Resultado: Se incluyeron 43 pacientes. La media de edad fue de 64.7 (DE 16) años. La principal causa de la falla respiratoria fue la neumonía en 18 pacientes (42%). Se observó que la frecuencia respiratoria disminuyó 8 respiraciones por minuto (p < .001), la frecuencia cardiaca disminuyó 7 latidos por minuto (p < .001) y la puntuación de la disnea disminuyó 2 puntos (p < .001). Conclusiones: Se observó una disminución significativa de las tres variables estudiadas en los pacientes que acudieron a la central de emergencias con falla respiratoria aguda hipoxémica, con la utilización de un dispositivo de oxigenoterapia no convencional, el cual podría considerarse en países con recursos limitados o en los escenarios de superpoblación, tan frecuentes en las centrales de emergencia.

ABSTRACT

Objective: To describe changes observed in respiratory rate, heart rate and dyspnea score before and after using an alternative highflow nasal cannula device in patients with hypoxemic acute respiratory failure in an Emergency Department. Materials and Method: Quasi-experimental, retrospective study with adult patients who went to the Emergency Department with clinical signs of hypoxemic acute respiratory failure. Data from respiratory rate, heart rate and dyspnea score were gathered from the electronic medical records of the patients both before and after using a Venturi device connected to a high-flow nasal cannula system two hours. Result: 43 patients were included. The mean age was 64.7 years (SD 16). The main cause of respiratory failure was pneumonia in 18 patients (42%). We observed a decrease of 8 breaths per minute (p < .001) in the respiratory rate, and 7 beats per minute (p < .001) in the heart rate; and there was a 2-point decrease in the dyspnea score (p < .001). Conclusions: We observed a significant decrease in the three variables under study in patients who went to the Emergency Department with hypoxemic acute respiratory failure, using a non-conventional oxygen therapy device, which could become useful in countries with limited resources or in cases of overcrowding, so common in the Emergency Departments

ABSTRACT

Abstract Bovine leukemia virus (BLV) is an important cattle pathogen that causes major economic losses worldwide, especially in dairy farms. The use of animal models provides valuable insight into the pathogenesis of viral infections. Experimental infections of sheep have been conducted using blood from BLV-infected cattle, infectious BLV molecular clones or tumor-derived cells. The Fetal Lamb Kidney cell line, persistently infected with BLV (FLK-BLV), is one of the most commonly used long-term culture available for the permanent production of virus. FLK-BLV cells or the viral particles obtained from the cell-free culture supernatant could be used as a source of provirus or virus to experimentally infect sheep. In this report, we aimed to determine the minimum amount of FLK-BLV cells or cell-free supernatant containing BLV needed to produce infection in sheep. We also evaluated the amount of antibodies obtained from a naturally-infected cow required to neutralize this infection. We observed that both sheep experimentally inoculated with 5000 FLK-BLV cells became infected, as well as one of the sheep receiving 500 FLK-BLV cells. None of the animals inoculated with 50 FLK-BLV cells showed evidence of infection. The cell-free FLK-BLV supernatant proved to be infective in sheep up to a 1:1000 dilution. Specific BLV antibodies showed neutralizing activity as none of the sheep became infected. Conversely, the animals receiving a BLV-negative serum showed signs of BLV infection. These results contribute to the optimization of a sheep bioassay which could be useful to further characterize BLV infection.


Resumen El virus de la leucosis bovina (bovine leukemia virus [BLV]) es un importante agente patógeno del ganado que causa importantes pérdidas económicas en todo el mundo, especialmente en los rodeos lecheros. El uso de modelos animales proporciona información valiosa sobre la patogénesis de las infecciones virales. Se realizaron infecciones experimentales en ovejas usando sangre de bovinos infectados con BLV, clones moleculares de BLV infecciosos o células derivadas de tumores. La línea celular Fetal Lamb Kidney, persistentemente infectada con el BLV (FLK-BLV), es uno de los cultivos a largo plazo más utilizados para la producción permanente de virus. Las células FLK-BLV o las partículas virales obtenidas del sobrenadante del cultivo libre de células podrían usarse como fuente de provirus o de virus para infectar experimentalmente ovejas. En este trabajo, nuestro objetivo fue determinar la cantidad mínima de células FLK-BLV o de sobrenadante libre de células que contiene BLV necesaria para producir infección en ovejas. También evaluamos la cantidad de anticuerpos bovinos anti-BLV necesaria para neutralizar la infección. Observamos que las dos ovejas inoculadas experimentalmente con 5000 células FLK-BLV se infectaron, y que una de las dos ovejas que recibieron 500 células FLK-BLV se infectó. Ninguno de los animales inoculados con 50 células FLK-BLV mostró evidencia de infección. El sobrenadante FLK-BLV libre de células demostró ser infectivo en ovejas hasta la dilución 1:1000. Los anticuerpos BLV específicos mostraron actividad neutralizante, ya que ninguna de las ovejas se infectó. Por el contrario, los animales que recibieron un suero BLV negativo mostraron signos de infección por BLV. Estos resultados contribuyen a la optimización de un bioensayo en ovejas útil para caracterizar la infección por BLV.

ABSTRACT

Objetivo: Describir las características de los pacientes con Influenza A subtipo H3N2 y requerimiento de soporte ventilatorio durante el brote del 2017, así como la evolución y los resultados clínicos. Materiales y métodos: Cohorte retrospectiva. Se incluyeron todos los pacientes con diagnóstico confirmado de H3N2 durante el mes de junio 2017 con requerimientos de asistencia respiratoria mecánica invasivo, no invasivo, terapia de alto flujo por cánula nasal y/o presión continua en la vía aérea que consultaron a la central de emergencias. Resultados: Se incluyeron 34 pacientes, 52.9% hombres, media de edad 81 (DE 10) años. Las principales comorbilidades de los pacientes al ingreso fueron: 73.5% hipertensión arterial, 44.1% enfermedad pulmonar obstructiva crónica y 76.5% insuficiencia cardíaca congestiva. La media del score de Charlson fue de 6 (DE 2), la mediana de APACHE II fue de 17 (IIC 14-20) y la de SOFA al día 1 de 5 (IIC 3-7). Al ingreso, 23 pacientes requirieron ventilación no invasiva, 5 presión continua en la vía aérea, 4 asistencia respiratoria mecánica invasiva y 2 terapia de alto flujo. Se registró un 47.8% (IC95% 26.8-69.4) de falla de la ventilación no invasiva y finalmente el 38.2% fueron intubados y ventilados mecánicamente. La mortalidad hospitalaria fue de 52.9% (IC95% 35.1-70.2). Conclusiones: se observó una alta mortalidad en una población añosa y comórbida durante el brote de H3N2. La mayoría realizó una prueba de ventilación no invasiva al ingreso, un alto porcentaje falló. El cuadro inicial pudo ser interpretado como enfermedad pulmonar obstructiva crónica reagudizada y/o insuficiencia cardíaca congestiva.

ABSTRACT

Objective: To describe the characteristics of patients with influenza A subtype H3N2 requiring ventilatory support during the 2017 outbreak, as well as the evolution of the disease and clinical results. Materials and Methods: Retrospective cohort. We included all patients admitted to the Emergency Department with confirmed diagnosis of H3N2 during June 2017, requiring invasive or noninvasive mechanical respiratory assistance, high-flow nasal cannula treatment or continuous airway pressure. Results: 34 patients were included; 52.9% men, mean age 81 years (Standard Deviation [SD] 10). Main comorbidities of patients on admission were: 73.5% hypertension, 44.1% chronic obstructive pulmonary disease and 76.5% congestive heart failure. The mean Charlson Index score was 6 (SD 2), the APACHE II median (Acute Physiology and Chronic Health Evaluation II) was 17 (IQR 14-20) and the SOFA median (Sequential Organ Failure Assessment) on day 1 was 5 (IQR 3-7). On admission, 23 patients required noninvasive ventilation, 5 continuous positive airway pressure, 4 invasive mechanical ventilation and 2 high-flow nasal cannula therapy. The rate of noninvasive ventilation failure was 47.8% (95% CI [confidence interval] 26.8-69.4) and finally 38.2% of patients were intubated and mechanically ventilated. Hospital mortality was 52.9% (95% CI 35.1-70.2). Conclusions: A high mortality rate was observed among elderly patients with comorbidities during the H3N2 outbreak. Most patients underwent a noninvasive ventilation trial on admission, however a high percentage failed. The initial condition could have been interpreted as acute chronic obstructive pulmonary disease or congestive heart failure.

ABSTRACT

La escasez de órganos para trasplante pulmonar es una problemática mundial. El soporte ventilatorio sub óptimo de los potenciales donantes cadavéricos tiene como consecuencia un aumento en el rechazo de los pulmones por los equipos de trasplante. El objetivo de la revisión es recopilar y organizar la información sobre el soporte ventilatorio del potencial donante pulmonar cadavérico y las estrategias ventilatorias disponibles para optimizar los pulmones antes de su ablación.


The shortage of cadaveric organ donors for lung transplantation is a global problem. One of the consequences of poor ventilatory support in potential lung donors is an increase in organ rejection by the lung transplant team. The aim of the revision is to gather and compile information about ventilator support and strategies in potential lung donors to optimize organ condition before harvest.

ABSTRACT

Introducción: El 70-85% de la poblacion general sufre dolor lumbar. Se ha demostrado que los programas de Escuela de Columna son eficaces para el tratamiento de la lumbalgia cronica. El taping podria ser util para disminuir el dolor y normalizar la funcion muscular. El objetivo de este estudio fue evaluar la eficacia a corto y a largo plazo del taping combinado con la Escuela de Columna en el tratamiento de la lumbalgia cronica. Materiales y Métodos: Ensayo clinico controlado aleatorizado. El grupo experimental utilizo cinta (tape) y realizo Escuela de Columna, y el grupo de control solo realizo Escuela de Columna. Al comienzo y al final del tratamiento, se registraron el dolor con la escala analogica visual, la flexibilidad con el Modified Finger Tip-to-Floor Test y la funcionalidad con el Roland Morris Disability Questionnaire. Solo al inicio se midio la depresion con el Beck Depression Inventory. Resultados: Se incluyeron 220 pacientes, solo 42 del grupo experimental y 33 del grupo de control completaron el tratamiento. El delta de dolor entre la primera y la quinta sesion no mostro diferencias entre los grupos, independientemente del tiempo (p = 0,329). Tampoco hubo diferencias entre los grupos en las determinaciones de depresion, funcionalidad (p = 0,75) y flexibilidad (p = 0,20). Conclusión: El taping combinado con Escuela de Columna comparado con el tratamiento exclusivo de Escuela de Columna no resulto mas eficaz para disminuir el dolor, aumentar la funcionalidad y la flexibilidad en los pacientes con lumbalgia cronica.


Introduction: From 70% to 85% of the general population suffers from back pain. Back School programs have been effective in the treatment of chronic low back pain. Taping may be useful in reducing pain and normalizing muscle function. The objective of this study was to evaluate the short- and long-term effectiveness of combining taping with Back School. Methods: Randomized controlled clinical trial. The experimental group used tape and made Back School and the control group only made Back School. At the beginning and the end of treatment, pain was evaluated with a visual analogue scale, the flexibility was determined with the Modified Finger Tip-to-Floor Test and functionality was calculated with the Roland Morris Disability Questionnaire. Depression was recorded with the Depression Beck Inventory just at the beginning. Results: Two hundred and twenty patients were enrolled, only 42 in the experimental group and 33 in the control group completed the treatment. Pain variation between the first and the fifth session showed no differences between groups regardless of time (p = 0.329). There were no differences between groups in functionality (p = 0.75), flexibility (p = 0.20) and depression. Conclusion: The combination of taping and Back School compared with only Back School was not more effective in reducing pain, increasing functionality and flexibility in patients with chronic low back pain.
