Acute Aortic Dissection Type A in Younger Patients (< 60 Years Old) - Does Full Arch Replacement Provide Benefits Compared to Limited Approach?

ABSTRACT Introduction: Acute aortic dissection Stanford type A (AADA) is a surgical emergency associated with high morbidity and mortality. Although surgical management has improved, the optimal therapy is a matter of debate. Different surgical strategies have been proposed for patients under 60 years old. This paper evaluates the postoperative outcome and the need for secondary aortic operation after a limited surgical approach (proximal arch replacement) vs. extended arch repair. Methods: Between January 2000 and January 2018, 530 patients received surgical treatment for AADA at our hospital; 182 were under 60 years old and were enrolled in this study - Group A (n=68), limited arch repair (proximal arch replacement), and group B (n=114), extended arch repair (> proximal arch replacement). Results: More pericardial tamponade (P=0.005) and preoperative mechanical resuscitation (P=0.014) were seen in Group A. More need for renal replacement therapy (P=0.047) was seen in the full arch group. Mechanical ventilation time (P=0.022) and intensive care unit stay (P<0.001) were shorter in the limited repair group. Thirty-day mortality was comparable (P=0.117). New onset of postoperative stroke was comparable (Group A four patients [5.9%] vs. Group B 15 patients [13.2%]; P=0.120). Long-term follow-up did not differ significantly for secondary aortic surgery. Conclusion: Even though young patients received only limited arch repair, the outcome was comparable. Full-arch replacement was not beneficial in the long-time follow-up. A limited approach is justified in the cohort of young AADA patients. Exemptions, like known Marfan syndrome and the presence of an intimal tear in the arch, should be considered.

Noninvasive mechanical ventilation assistance in amyotrophic lateral sclerosis: a systematic review

ABSTRACT BACKGROUND: Respiratory failure is the most common cause of death in patients with amyotrophic lateral sclerosis (ALS), and morbidity is related to poor quality of life (QOL). Non-invasive ventilation (NIV) may be associated with prolonged survival and QOL in patients with ALS. OBJECTIVES: To assess whether NIV is effective and safe for patients with ALS in terms of survival and QOL, alerting the health system. DESIGN AND SETTING: Systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting standards using population, intervention, comparison, and outcome strategies. METHODS: The Cochrane Library, CENTRAL, MEDLINE, LILACS, EMBASE, and CRD databases were searched based on the eligibility criteria for all types of studies on NIV use in patients with ALS published up to January 2022. Data were extracted from the included studies, and the findings were presented using a narrative synthesis. RESULTS: Of the 120 papers identified, only 14 were related to systematic reviews. After thorough reading, only one meta-analysis was considered eligible. In the second stage, 248 studies were included; however, only one systematic review was included. The results demonstrated that NIV provided relief from the symptoms of chronic hypoventilation, increased survival, and improved QOL compared to standard care. These results varied according to clinical phenotype. CONCLUSIONS: NIV in patients with ALS improves the outcome and can delay the indication for tracheostomy, reducing expenditure on hospitalization and occupancy of intensive care unit beds.

Outcomes of Minimally Invasive Aortic Valve Replacement in Obese Patients: A Propensity-Matched Study

ABSTRACT Introduction: Obese patients are at risk of complications after cardiac surgery. The aim of this study is to investigate safety and efficacy of a minimally invasive approach via upper sternotomy in this setting. Methods: We retrospectively reviewed 203 obese patients who underwent isolated, elective aortic valve replacement between January 2014 and January 2023 - 106 with minimally invasive aortic valve replacement (MIAVR) and 97 with conventional aortic valve replacement (CAVR). To account for baseline differences, a propensity-matching analysis was performed obtaining two balanced groups of 91 patients each. Results: The 30-day mortality rate was comparable between groups (1.1% MIAVR vs. 0% CAVR, P=0.99). MIAVR patients had faster extubation than CAVR patients (6 ± 2 vs. 9 ± 2 hours, P<0.01). Continuous positive airway pressure therapy was less common in the MIAVR than in the CAVR group (3.3% vs. 13.2%, P=0.03). Other postoperative complications did not differ significantly. Intensive care unit stay (1.8 ± 1.2 vs. 3.2 ± 1.4 days, P<0.01), but not hospital stay (6.7 ± 2.1 vs. 7.2 ± 1.9 days, P=0.09), was shorter for MIAVR than for CAVR patients. Follow-up survival was comparable (logrank P-value = 0.58). Conclusion: MIAVR via upper sternotomy has been shown to be a safe and effective option for obese patients. Respiratory outcome was promising with shorter mechanical ventilation time and reduced need for post-extubation support. The length of stay in the intensive care unit was reduced. These advantages might be important for the obese patient to whom minimally invasive surgery should not be denied.

Risk factors of self-extubation in intensive care. Retrospective cohort study

Introduction Acute respiratory failure remains one of the three leading causes of admission to the intensive care unit (ICU). Self-extubation is an adverse outcome requiring reintubation in 50% of cases. Objective To assess for determinants (risk factors) of self-extubation and mortality in the ICU by using a generalized estimation equation model (GEE). Methods The data was collected from a retrospective cohort study from 2017-2020 including all patients admitted to the ICU with mechanical ventilation. Univariate and bivariate analyses were performed. Then, a GEE model was conducted to predict the risk of self-extubation and mortality. Results A total of 857 subjects were included, with a mean age of 60.5 +/- 17 years-old. Most of the subjects were males (55.2%). An 8.99-fold risk (95%CI 3.83-21.1, p<0.0i) of self-extubation was identified in patients with agitation. Exposure to infusion of neuromuscular blockade was also found to increase the risk of self-extubation 3.37 times (95%CI 1.31-8.68, p=0.01). No associations were identified between immobilization and self-extubation (OR 1.38 95%CI 0.76-2.51, p=0.29). Finally, light sedation according to the Richmond Sedation Scale (RASS) between 0 to -2 rather than moderate (RASS-3) reduces the risk of mortality (OR 0.57, 95%CI 0.38-0.83, p<0.01). Conclusions The main factors resulting in self-extubation were: agitation, delirium, and infusion of neuromuscular blocking agents. An association was found between light sedation and a lower risk of mortality. No association was found between the use of physical restraint and the desired outcome.

Introducción: La insuficiencia respiratoria aguda continúa siendo una de las tres causas principales de ingreso a la unidad de cuidado intensivo (UCI). La auto-extubación es un desenlace adverso que requiere re-intubación en un 50% de los casos. Objetivo: Evaluar los determinantes (factores de riesgo) de la auto-extubación y la mortalidad en UCI mediante el uso de un modelo de ecuaciones de estimación generalizadas (EEG). Métodos: Estudio de una cohorte retrospectiva realizada durante el periodo 2017-2020 incluyendo a todos los pacientes ingresados a UCI con ventilación mecánica invasiva. Se realizaron análisis univariado y bivariado. Adicionalmente, se utilizó un modelo EEG para predecir el riesgo de auto-extubación y mortalidad. Resultados: Se analizó un total de 857 pacientes con un promedio de edad entre 60,5 +/-17 años, siendo hombres en su mayoría (55,2%). Se encontró un riesgo 8,99 veces mayor (IC95% 3,83-21,1, p<0,01) de auto-extubación en los pacientes con agitación. La infusión de relajación muscular incrementó el riesgo de auto-extubación en 3,37 veces (IC95% 1,318,68, p=0,01). No se encontró asociación entre inmovilización y auto-extubación (OR 1,38 IC95% 0,76-2,51, p=0,29). Finalmente, una sedación ligera según la Escala de Sedación de Richmond (RASS) entre 0 a -2 en lugar de moderada (RASS-3) redujo el riesgo de mortalidad (OR 0,5 IC95% 0,38-0,83, p<0.01). Conclusiones: Los principales factores asociados a auto-extubación fueron agitación, delirium e infusión de relajantes musculares. Se encontró asociación entre una sedación ligera y menor riesgo de mortalidad. No se encontró asociación entre el uso de la restricción física y el desenlace de interés.

Salud bucal en pacientes en estado crítico / Critical patient oral health

Fundamento: La salud bucal y sus cuidados son importantes en la atención sanitaria de pacientes en estado crítico. Objetivo: Proporcionar una visión general de los vínculos entre la salud bucal y los resultados adversos en la evolución de los pacientes en estado crítico. Metodología: Esta revisión narrativa se realizó en Google Académico, PubMed/Medline y SciELO, con los descriptores salud bucal, cuidados críticos, respiración artificial y neumonía asociada al ventilador, consultados en el DeCS. Se seleccionaron artículos a texto completo en español e inglés de revistas arbitradas por pares y de los últimos 5 años. Resultados: La disbiosis y la mala higiene bucales propician la aparición y desarrollo de enfermedades bucales que, a su vez, favorecen la incidencia de enfermedades respiratorias bajas como la neumonía asociada al ventilador en pacientes en estado crítico. Dentro de los factores vinculantes están la aspiración de secreciones bucales con bacterias patógenas que colonizan el tracto respiratorio inferior y los trastornos nutricionales que reducen el sistema defensivo. Aunque existen algunas discrepancias, la mayoría de los estudios apoyan las medidas de cuidado bucal en los pacientes en estado crítico. Conclusiones: La salud y cuidados bucales son claves para un desenlace clínico más favorable en los pacientes en estado crítico.

Background: Oral health and oral health care are important in the health care of critically ill patients. Objective: To provide an overview of the relationship between oral health and adverse outcomes in critically ill patients. Methodology: This narrative revision was conducted in Google Scholar, PubMed/Medline and SciELO, with the descriptors oral health, critical care, artificial respiration and ventilator-associated pneumonia consulted in the DeCS. Full-text articles in Spanish and English from peer-reviewed journals and from the last 5 years were selected. Results: Dysbiosis and poor oral hygiene promote the incidence and development of oral diseases, which in turn promote the incidence of lower respiratory system diseases such as ventilator-associated pneumonia in critically ill patients. Among the factors involved are aspiration of oral secretions with pathogenic bacteria that colonize the lower respiratory tract, and nutritional deficiencies that compromise the immune system. Although there are some discrepancies, most studies support oral care practices in critically ill patients. Conclusions: The health and care of the oral cavity is the key to a more favorable outcome for critically ill patients.

O modo PSV apresenta piores desfechos em relação ao desmame quando comparado com outros modos ventilatórios de pacientes com exacerbação aguda da doença pulmonar obstrutiva crônica: revisão sistemática / The PSV mode has worse weaning outcomes when compared to other ventilatory modes in patients with an acute exacerbation of chronic obstructive pulmonary disease: systematic review

INTRODUÇÃO: A Doença Pulmonar Obstrutiva Crônica (DPOC) é um distúrbio crônico e progressivo, que evolui com o declínio da função pulmonar. Embora sua cronicidade, são comuns períodos de agudização acompanhados de Insuficiência Respiratória Aguda hipercápnica, requisitando permanência nas Unidades de Terapia Intensiva (UTI) e Ventilação Mecânica Invasiva (VMI) para reversão da falência respiratória. O desmame na DPOC ocupa até 58% da VM, logo, se faz necessário estratégias específicas para otimização desse processo, com a utilização de modos e ajustes ventilatórios que promovam um desmame precoce e efetivo. OBJETIVO: Verificar os efeitos da Ventilação com Pressão de Suporte quando comparado com modos e estratégias distintas no desmame de pacientes com DPOC. MÉTODOS: Revisão sistemática, construída seguindo critérios do PRISMA, registrada na PROSPERO (CRD42022362228). Considerados elegíveis ensaios clínicos controlados randomizados que avaliaram o modo PSV em comparação com modos e estratégias distintas, em pacientes com diagnóstico de DPOC, em VMI, sem delimitação de ano/idioma. Foram excluídos artigos incompletos, duplicados e indisponíveis aos recursos de recuperação. Desfechos de interesse foram: duração do desmame, tempo de permanência na UTI e mortalidade. A estratégia foi aplicada nas bases: PubMed, Cochrane, SciELO, e Biblioteca Virtual em Saúde. As ferramentas Escala PEDro e RevMan Web foram utilizadas para análise da qualidade dos estudos e risco de viés, respectivamente. RESULTADOS: Incluídos 8 artigos. 6 mostraram significância estatística, apresentando menor tempo de desmame no grupo ASV (24 (20­62) h versus 72 (24­144) h PSV) (p=0,041); mais dias na UTI quando comparado com o modo PAV (p<0,001). PSV foi mais eficaz nos mesmos desfechos quando comparado com a estratégia Tubo-T. Houve diferenças quanto a taxa de mortalidade com o modo NAVA. CONCLUSÃO: Fica evidente que o modo PSV quando em relação a modos ventilatórios assistidos, tem potencial de fornecer piores desfechos associados ao processo de desmame da ventilação invasiva de pacientes com DPOC.

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) is a chronic and progressive disorder that evolves with the decline in lung function. Despite its chronicity, periods of exacerbation accompanied by hypercapnic Acute Respiratory Failure are common, requiring a stay in Intensive Care Units (ICU) and Invasive Mechanical Ventilation (IMV) to reverse respiratory failure. Weaning in COPD occupies up to 58% of the MV, therefore, specific strategies are needed to optimize this process, using ventilatory modes and adjustments that promote early and effective weaning. OBJECTIVE: To verify the effects of Pressure Support Ventilation when compared with different modes and strategies in weaning patients with COPD. METHODS: Systematic review, constructed following PRISMA criteria, registered at PROSPERO (CRD42022362228). Randomized controlled clinical trials that evaluated the PSV mode in comparison with different modes and strategies, in patients diagnosed with COPD, on IMV, without delimitation of year/language, were considered eligible. Incomplete, duplicate and unavailable articles were excluded. Outcomes of interest were: duration of weaning, length of stay in the ICU and mortality. The strategy was applied in the bases: PubMed, Cochrane, SciELO, and Biblioteca Virtual em Saúde. The PEDro Scale and RevMan Web tools were used to analyze study quality and risk of bias, respectively. RESULTS: Included 8 articles. 6 showed statistical significance, showing shorter weaning time in the ASV group (24 (20­62) h versus 72 (24­144) h PSV) (p=0.041), and more days in the ICU when compared to the PAV mode (p<0.001). PSV was more effective on the same outcomes when compared with the T-tube strategy. There were differences in the mortality rate with the NAVA mode. CONCLUSION: It is evident that the PSV mode, when compared to assisted ventilation modes, has the potential to provide worse outcomes associated with the process of weaning from invasive ventilation in patients with COPD.

Autonomic heart rate modulation in patients with coronavirus disease 2019 in mechanical ventilation

SUMMARY BACKGROUND: Patients with coronavirus disease 2019 on automatic mechanical ventilation have greater heart rate modulation with greater parasympathetic modulation. OBJECTIVE: To analyze the autonomic modulation of heart rate in critically ill patients with coronavirus disease 2019 on invasive mechanical ventilation. METHODS: A cross-section study was carried out with 36 individuals divided into two groups. The control group included patients of both genders, in orotracheal intubation with invasive mechanical ventilation under controlled assisted mode, hospitalized in the intensive care unit for another 24 h. In the non-COVID group, patients diagnosed with coronavirus disease 2019 in the same condition mentioned in the control group. RESULTS: There was a significant increase in heart rate variability (standard deviation of all normal RR intervals recorded at an interval of time; p=0.001; triangular interpolation histogram of RR intervals; p=0.048; and SD2; p=0.014) in the coronavirus disease group compared to the non-COVID group. Successively, the parameters that demonstrate parasympathetic modulation are shown to be higher in the group of patients with coronavirus disease 2019 (root mean square of the square of differences between adjacent normal RR intervals in an interval of time; p<0.001; pNN50; p<0.001; SD1; p=0.002; and high frequency; p=0.022). CONCLUSIONS: There was a greater autonomic modulation of heart rate with a greater parasympathetic modulation in patients with coronavirus disease 2019 on mechanical ventilation.

Factores de riesgo para destete fallido de la ventilación mecánica en adultos

Introducción: El destete o liberación de la ventilación mecánica (VM) es un proceso complejo y cuando es fallido aumentará los riesgos de complicaciones y gastos. Objetivo: Identificar factores de riesgo modificables para destete fallido en adultos con VM. Materiales y Métodos: Estudio de casos y controles realizado en pacientes ≥ 18 años ingresados en la unidad de cuidados intensivos de un hospital de tercer nivel. Los casos se identificaron como destete fallido (DF) del VM y los controles como destete simple. Se excluyeron los pacientes procedentes de otro hospital con VM. Los factores estudiados fueron el alto riesgo nutricional por el Nutric score modificado, la nutrición enteral tardía, el balance hídrico (BH) positivo y la ausencia de fisioterapia previos al destete. Se calculo el OR con una significancia < 0,05 para el análisis bivariado, multivariado y ajustado. Resultados: Se incluyeron 105 pacientes, 35 casos y 70 controles. El análisis bivariado encontró que el alto riesgo nutricional (OR = 2.5; IC 95% = 1,1 5,9; p=0,027) fue factor de riesgo, pero el análisis multivariado no lo confirmó. La nutrición enteral tardía (OR = 1,2; IC 95% = 0,4 3,4), el BH positivo (OR = 0,7; IC 95% = 0,3 1,7) y la ausencia de fisioterapia respiratoria (OR = 0,2; IC 95% = 0,004 0,011) no fueron factores de riesgo para DF. Conclusiones: El alto riesgo nutricional, la nutrición enteral tardía, el BH positivo y la ausencia de fisioterapia respiratoria antes del destete no fueron factores de riesgo para DF.

Background: Weaning of the mechanical ventilation (MV) is a complex process and when it fails, it can increase the risks of complications and expenses in health systems. Objective: To identify risk factors for failed weaning in adults with MV. Materials and Methods: Case-control study carried out in patients older than 18 years admitted to the intensive care unit of a tertiary care hospital. Cases were identified as failed weaning (FW) of MV, and controls were simple weaning. Patients from another hospital with MV were excluded. Risk factors studied were high nutritional risk by the modified Nutric score, late enteral nutrition, positive water balance (WB) and the absence of physical therapy prior to weaning. OR was calculated with a significance < 0.05 for bivariate, multivariate, and adjusted analysis. Results: 105 patients were included, 35 cases and 70 controls. The bivariate analysis found that high nutritional risk (OR = 2.5; 95% CI = 1.1 5.9; p = 0.027) was a risk factor, but the multivariate analysis did not confirm it. Late enteral nutrition (OR = 1.2; 95% CI = 0.4 3.4), positive WB (OR = 0.7; 95% CI = 0.3 1.7) and the absence of respiratory physiotherapy (OR = 0.2; 95% CI = 0.004 0.011) were not risk factors for FW. Conclusions: High nutritional risk, late enteral nutrition, positive BH and the absence of respiratory physiotherapy before weaning were not risk factors for FW.

Using Revolution™ CT Angiography to Assess Complex Coarctation of the Aorta in Infants and Its Association with a Prolonged Postoperative Cardiac ICU Stay

ABSTRACT Objective: To investigate the accuracy of aortic dimensions measured by Revolution™ computed tomography (CT) in infants with complex coarctation of the aorta (CoA) and to further analyze the utility of the degree of CoA in predicting the risk of prolonged postoperative cardiac intensive care unit stay. Methods: A total of 30 infants with complex CoA who underwent surgical correction from January 2020 to July 2022 were retrospectively enrolled. General demographic data, preoperative imaging, and perioperative outcomes were collected. Univariate and multivariate analyses were performed to investigate predictors of prolonged postoperative cardiac intensive care unit stay, and the reliability of the CT measurements was assessed by the intraclass correlation coefficient. Results: All infants were divided into a mild or severe CoA group. The duration of mechanical ventilation and cardiac intensive care unit stay in the mild CoA group were significantly lower than those in the severe CoA group. After multivariate analysis, we found that the degree of CoA and age at surgery were significant predictors of prolonged postoperative cardiac intensive care unit stay. The intraclass correlation coefficient between CT measurements and intraoperative measurements was between 0.937 and 0.975, and the measurement results had good reliability. Conclusion: CT angiography can provide a comprehensive and accurate preoperative evaluation of aortic dimensions measured in infants with complex CoA. The degree of CoA is an independent risk factor for prolonged postoperative cardiac intensive care unit stay in infants with complex CoA.

Lesão Miocárdica e Prognóstico em Pacientes Hospitalizados com COVID-19 no Brasil: Resultados do Registro Nacional de COVID-19 / Myocardial Injury and Prognosis in Hospitalized COVID-19 Patients in Brazil: Results From The Brazilian COVID-19 Registry

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease's pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Cuidado de enfermería durante el proceso de extubación: desde la teoría de Kristen Swanson / Nursing care during the extubation process: from the theory of Kristen Swanson

INTRODUCCIÓN: El creciente aumento de la incidencia del soporte ventilatorio mecánico ha impulsado el interés y desarrollo de estudios para mejorar la conducción de este proceso, sin embargo, conocer las experiencias que han vivido los profesionales de enfermería durante la extubación, puede contribuir a mejorar las prácticas de cuidado para hacer el proceso más humanizado y hacer de la UCI un lugar más ameno para la recuperación. OBJETIVO: Describir la percepción de profesionales de enfermería sobre los cuidados durante el proceso de weaning sustentado en los principios teóricos de Kristen Swanson. MÉTODOS: Estudio descriptivo, en base a un diseño fenomenológico según Husserl. La recogida de datos se realizó a través de una entrevista realizada por Google Meet, grabada en audio y luego transcrita a texto. El proceso de análisis formal estuvo orientado por los 9 pasos de Colaizzi. Para aumentar la credibilidad y precisión de la investigación se utilizaron los criterios de rigor propuestos por Lincoln y Guba. RESULTADOS: Emergieron 15 temas relacionados a los procesos de cuidado de Swanson. Se encontraron hallazgos en relación a cuidados integrales en contexto de extubación; encontrar significado al proceso de destete como experiencia de vida y la relación profesional-paciente en la extubación. CONCLUSIÓN: La experiencia al entregar cuidados durante el proceso de extubación deja en evidencia la importancia que otorgan no solo a aspectos hemodinámicos, fisiológicos y parámetros ventilatorios, sino que también a favorecer que la experiencia del destete sea realizada en un contexto de integralidad, seguridad, calidad, humanismo y respeto por sus derechos.

INTRODUCTION: The increasing incidence of mechanical ventilatory support has prompted an interest in and development of studies to improve the process, and knowing the experiences of nursing professionals during extubation can contribute to the improvement of care practices to make it more humanized as well as make the ICU a more pleasant place for recovery. OBJECTIVE: To describe nursing professionals' perception of care during the weaning process based on Kristen Swanson's theoretical principles. METHODS: Descriptive study, based on a phenomenological design according to Husserl. Data collection was done through an interview conducted by Google Meet, audio-recorded and then transcribed to text. The formal analysis process was guided by Colaizzi's 9 steps. To increase the credibility and accuracy of the research, the rigor criteria proposed by Lincoln and Guba were used. RESULTS: Fifteen themes related to Swanson's care processes emerged. Findings related to comprehensive care in the context of extubation were found, including finding meaning in the weaning process as a life experience, and the professional-patient relationship in extubation. CONCLUSION: The experience of providing care during the extubation process shows the importance they attach not only to hemodynamic, physiological and ventilatory parameters, but also to ensuring that the weaning experience is carried out in a context of integrality, safety, quality, humanism and respect for their rights.

Mechanical power measurement during mechanical ventilation of SARS-CoV-2 critically ill patients. A cohort study / Medición del poder mecánico durante ventilación mecánica en pacientes críticamente enfermos con SARS-CoV-2, Estudio de cohorte

Abstract Introduction: The ventilator-induced lung injury (VILI) depends on the amount of energy per minute transferred by the ventilator to the lung measured in Joules, which is called mechanical power. Mechanical power is a development variable probably associated with outcomes in ventilated patients. Objective: To describe the value of mechanical power in patients with SARS-CoV-2 infection and ventilated for other causes and its relationship between days of mechanical ventilation, length of stay in the intensive care unit (ICU), and mortality. Methods: A multicenter, analytical, observational cohort study was conducted in patients with SARS-CoV-2 infection who required invasive mechanical ventilation and patients ventilated for other causes for more than 24 hours. Results: The cohort included 91 patients on mechanical ventilation in three tertiary care centers in the city of Pereira, Colombia. The average value of the mechanical power found was 22.7 ± 1 Joules/ min. In the subgroup of patients with SARS-CoV-2 infection, the value of mechanical power was higher 26.8 ± 9 than in the subgroup of patients without a diagnosis of SARS-CoV-2 infection 18.2 ± 1 (p <0.001). Conclusions: Mechanical power is an important variable to consider during the monitoring of mechanical ventilation. This study found an average value of mechanical power of 22.7 ± 1 Joules/min, being higher in patients with SARS-CoV-2 infection related to longer days of mechanical ventilation and a longer stay in the ICU.

Resumen Introducción: La lesión pulmonar inducida por la ventilación mecánica (LPIVM) depende, entre otras variables, de la cantidad de energía -medida en Joules- por unidad de tiempo transferida desde el ventilador al paciente, también llamada poder mecánico. El poder mecánico es una variable de desarrollo, posiblemente asociada a los desenlaces en pacientes sometidos a ventilación. Objetivo: Describir el valor del poder mecánico en pacientes con infección por SARS-CoV-2 y ventilados por otras causas y la relación entre días de ventilación mecánica, estancia en la UCI y mortalidad. Métodos: Estudio multicéntrico, analítico y observacional de cohorte realizado en pacientes con diagnóstico de infección por SARS-CoV-2 que requirieron soporte ventilatorio mecánico invasivo y pacientes ventilados por otras causas, durante más de 24 horas. Resultados: La cohorte incluyó 91 pacientes que recibieron ventilación mecánica en 3 centros de tercer nivel de la ciudad de Pereira, Colombia. El valor promedio del poder mecánico obtenido fue 22,7 ± 1 Joules/min. En el grupo de pacientes con infección por SARS-CoV-2 el valor obtenido fue mayor (26,8 ± 9), comparado con el grupo de pacientes sin infección por SARS-CoV-2 (18,2 ± 1) (p <0,001). Conclusiones: El poder mecánico es una variable importante a tener en cuenta en el monitoreo de la ventilación mecánica. El presente estudio encontró un valor promedio de poder mecánico de 22,7±1 Joules/min, siendo mayor en los pacientes con infección por SARS-CoV-2 en relación con más días de ventilación mecánica y estancia en UCI más prolongada.

Comparação de desfechos clínicos e correlação entre funcionalidade e tempo de ventilação mecânica de pacientes em uti / Comparison of clinical outcomes and correlation between functionality and time of mechanical ventilation in icu patients / Comparación de los resultados clínicos y correlación entre la funcionalidad y el tiempo de ventilación mecánica de los pacientes en uti

O objetivo deste estudo foi comparar os desfechos clínicos dos pacientes em suporte ventilatório invasivo por período curto e prolongado e correlacionar funcionalidade e tempo de ventilação mecânica (VM). Estudo documental retrospectivo, realizado na UTI neurocirúrgica de um hospital escola. Dos prontuários clínicos foram coletados: idade, sexo, hipótese diagnóstica de internação, tempo de internação e de VM em dias, o desfecho sucesso ou falha da extubação e o nível de funcionalidade. Os prontuários foram divididos em grupo um (GI): pacientes em VM por até três dias e grupo dois (GII): pacientes em VM por mais de três dias. Foram analisados 210 prontuários, 73% dos pacientes permaneceram menos de três dias em VM. A idade média de GI foi 51,8±15,5 anos e GII 48,7±16,3 anos (p=0,20), prevalência do sexo masculino em GI (59%) e GII (68%). O acidente vascular cerebral foi o diagnóstico mais prevalente no GI (18%) e o tumor cerebral no GII (21%) e hipertensão arterial, a comorbidade mais prevalente em GI (28%) e GII (25%). O GII permaneceu maior tempo (p<0,0001) em VM e internação na UTI que o GI e percentual de sucesso no desmame/extubação menor (p=0,01) que o GI. Não houve correlação significativa entre funcionalidade e tempo de VM em GI e GII (p>0,05). Os pacientes em suporte ventilatório invasivo por período prolongado evoluíram com maior permanência em VM, maior tempo de internação na UTI e menor taxa de sucesso no desmame/extubação. O tempo de permanência em suporte ventilatório invasivo não interferiu na funcionalidade desses pacientes.

The aim of this study was to compare the clinical outcomes of patients on short- and long-term invasive ventilatory support and to correlate functionality and duration of mechanical ventilation (MV). Retrospective documental study, carried out in the neurosurgical ICU of a teaching hospital. The following were collected from the clinical records: age, gender, diagnostic hypothesis of hospitalization, length of hospital stay and MV in days, the outcome of success or failure of extubation and the level of functionality. The medical records were divided into group one (GI): patients on MV for up to three days and group two (GII): patients on MV for more than three days. A total of 210 medical records were analyzed, 73% of the patients remained on MV for less than three days. The mean age of GI was 51.8±15.5 years and GII 48.7±16.3 years (p=0.20), male prevalence in GI (59%) and GII (68%). Stroke was the most prevalent diagnosis in GI (18%) and brain tumor in GII (21%) and hypertension was the most prevalent comorbidity in GI (28%) and GII (25%). GII remained longer (p<0.0001) in MV and ICU admission than GI and the percentage of success in weaning/extubation was lower (p=0.01) than GI. There was no significant correlation between functionality and time on MV in GI and GII (p>0.05). Patients on invasive ventilatory support for a long period evolved with longer MV stays, longer ICU stays and lower weaning/extubation success rates. The length of stay on invasive ventilatory support did not interfere with the functionality of these patients.

El objetivo de este estudio fue comparar los resultados clínicos de los pacientes con soporte ventilatorio invasivo a corto y largo plazo y correlacionar la funcionalidad y el tiempo de ventilación mecánica (VM). Se trata de un estudio documental retrospectivo, realizado en la UCI neuroquirúrgica de un hospital universitario. Se recogieron los siguientes datos de las historias clínicas: edad, sexo, hipótesis diagnóstica, duración de la estancia y tiempo de VM en días, el resultado éxito o fracaso de la extubación y el nivel de funcionalidad. Las historias clínicas se dividieron en el grupo uno (GI): pacientes bajo VM hasta tres días y el grupo dos (GII): pacientes bajo VM durante más de tres días. Se analizaron 210 historias clínicas, el 73% de los pacientes permanecieron menos de tres días con VM. La edad media de GI fue de 51,8±15,5 años y la de GII de 48,7±16,3 años (p=0,20), con prevalencia masculina en GI (59%) y GII (68%). El ictus fue el diagnóstico más prevalente en GI (18%) y el tumor cerebral en GII (21%) y la hipertensión, la comorbilidad más prevalente en GI (28%) y GII (25%). El GII permaneció más tiempo (p<0,0001) en la VM y la estancia en la UCI que el GI y el porcentaje de éxito en el destete/extubación fue menor (p=0,01) que el GI. No hubo correlación significativa entre la funcionalidad y el tiempo de VM en GI y GII (p>0,05). Los pacientes con soporte ventilatorio invasivo a largo plazo evolucionaron con una mayor estancia en la VM, una mayor estancia en la UCI y una menor tasa de éxito de destete/extubación. La duración de la estancia con soporte ventilatorio invasivo no interfirió en la funcionalidad de estos pacientes.

Continuous clonidine infusion: an alternative for children on mechanical ventilation

SUMMARY OBJECTIVE: This study aimed to assess the clonidine infusion rate in the first 6 h, as maintenance dose (first 24 h), and in the pre-extubation period (last 24 h), as well as the cumulative dose of other sedatives and the hemodynamic response. METHODS: This is a retrospective cohort study. RESULTS: Children up to the age of 2 years who were admitted to the pediatric intensive care unit of a tertiary referral hospital in the south region of Brazil, between January 2017 and December 2018, were submitted to mechanical ventilation, and received continuous clonidine infusions were included in the study. The initial, maintenance, and pre-extubation doses of clonidine; the vasoactive-inotropic score; heart rate; and systolic and diastolic blood pressure of the study participants were assessed. A total of 66 patients with a median age of 4 months who were receiving clonidine infusions were included. The main indications for mechanical ventilation were acute viral bronchiolitis (56%) and pneumonia associated with acute respiratory distress syndrome (15%). The median of clonidine infusion in the first 6 h (66 patients) was 0.53 μg/kg/h (IQR 0.49-0.88), followed by 0.85 μg/kg/h (IQR 0.53-1.03) during maintenance (57 patients) and 0.63 μg/kg/h (IQR 0.54-1.01) during extubation period (42 patients) (p=0.03). No differences were observed in the doses regarding the indication for mechanical ventilation. Clonidine infusion was not associated with hemodynamic changes and showed no differences when associated with adjuvants. CONCLUSION: Clonidine demonstrated to be a well-tolerated sedation option in pediatric patients submitted to mechanical ventilation, without relevant influence in hemodynamic variables.

Resultados de la ventilación asistida ajustada neuronalmente no invasiva y la presión positiva continua nasal en recién nacidos prematuros: revisión sistemática y metanálisis / Outcomes of noninvasive neurally adjusted ventilatory assist and nasal continuous positive airway pressure in preterm infants: a systematic review and meta-analysis

Introducción: los beneficios de la ventilación asistida ajustada neuronalmente (NAVA) en los recién nacidos prematuros son inciertos. El objetivo de este estudio fue explorar si la NAVA no invasiva (NIV) era más beneficiosa para los recién nacidos prematuros que la presión positiva continua nasal (NCPAP). Diseño del estudio: metanálisis de tres ensayos clínicos: dos ensayos controlados aleatorizados y un estudio de grupos cruzados. Se comparó la NAVA-NIV con la NCPAP y se informó sobre el fracaso del tratamiento, la mortalidad y los eventos adversos como resultados principales. Resultados: tres estudios con 173 pacientes (89 recibieron NAVA-NIV) cumplieron los criterios de inclusión en este metanálisis. No se observaron diferencias en el fracaso del tratamiento entre la NAVA-NIV y la NCPAP (razón de riesgos [RR] = 1,09; intervalo de confianza [IC] del 95 % = 0,65-1,84; diferencia de riesgos = 0,02; IC95% = -0,10-0,14; I2 = 33 %; P = 0,23). De manera similar, no hubo diferencias en la mortalidad (RR = 1,52; IC95% = 0,51-4,52; no aplica heterogeneidad). En comparación con la NCPAP, la NAVA-NIV redujo significativamente el uso de cafeína (RR = 0,85; IC 95% = 0,74-0,98; I2 = 71 %; P = 0,03). Conclusiones: en comparación con la NCPAP, no hay evidencia suficiente para sacar una conclusión sobre los beneficios o daños de la NAVA-NIV en los recién nacidos prematuros. Los hallazgos de esta revisión deben confirmarse en ensayos clínicos con una metodología rigurosa y potencia adecuada

Introduction: The benefits of neurally adjusted ventilatory assist (NAVA) in preterm infants are unclear. This study aimed to explore if noninvasive NAVA is more beneficial for preterm infants than nasal continuous positive airway pressure (NCPAP). Study design: Meta-analysis was performed in three clinical trials comprising two randomized controlled trials and one crossover study. We compared NIV-NAVA and NCPAP and reported treatment failure, mortality, and adverse events as the primary outcomes. Results: Three studies including 173 patients (89 of whom underwent NIV-NAVA) were eligible for this meta-analysis. This review found no difference in treatment failure between NIV-NAVA and NCPAP (RR 1.09, 95% CI 0.65 to 1.84; RD 0.02, 95% CI -0.10-0.14; I2=33%, P=0.23). Similarly, there was no difference in mortality (RR 1.52, 95% CI 0.51-4.52, heterogeneity not applicable). Compared with NCPAP, NIV-NAVA significantly reduced the use of caffeine (RR 0.85, 95% CI 0.74-0.98, I2=71%, P=0.03). Conclusions: Compared with NCPAP, there is insufficient evidence to conclude on the benefits or harm of NIV-NAVA therapy for preterm infants. The findings of this review should be confirmed using methodologically rigorous and adequately powered clinical trials.
