ABSTRACT
Introducción. Las cardiopatías congénitas (CC) en Chile corresponden a la segunda causa de muerte en menores de 1 año, requiriendo cirugías paliativas y/o correctivas el 65% de estas. En el post operatorio frecuentemente se utiliza ventilación mecánica invasiva (VM) y succión endotraqueal (SET) para remover secreciones. Sin embargo, la kinesiología respiratoria (KTR) ha mostrado mejoras significativas en la distensibilidad toracopulmonar (Cest) y resistencia de vía aérea (Rva) en otros grupos de usuarios pediátricos y adultos en VM. Objetivo. Comparar los cambios en la Cest y Rva en usuarios pediátricos en VM post cirugía de cardiopatía congénita (CCC) sometidos a KTR versus SET exclusiva. Métodos. Revisión sistemática de estudios publicados en bases de datos PUBMED, PeDro, Scielo y Google Scholar que comparan el uso de KTR ó SET sobre los cambios en mecánica ventilatoria en usuarios pediátricos en VM post cirugía de cardiopatía congénita, limitados a inglés, español y portugués, excluyendo a sujetos con traqueostomía o con oxigenación por membrana extracorpórea. Se utilizó guía PRISMA para la selección de artículos. Se revisaron 397 artículos y se seleccionó 1 artículo extra de los artículos sugeridos. Se eliminó 1 artículo por duplicidad. Por títulos y resúmenes se seleccionaron 2 artículos, los cuales al leer el texto completo fueron retirados debido a que la población no correspondía a cardiópatas. Resultados. El final de artículos seleccionados fue de 0 artículos, debido a lo cual se removió el operador Booleano "NOT", y se removió la población de cardiopatías. De este modo quedaron 2 artículos seleccionados para la revisión cualitativa final donde se compara KTR versus SET, y KTR en kinesiólogos especialistas y no especialistas, mostrando ambos aumento en la Cest y disminución de la Rva a favor de la KTR, hasta los 30 minutos post intervención. Conclusiones. No se encontraron artículos que demuestren cambios en Cest y Rva con el uso de KTR + SET versus SET exclusiva, en usuarios pediátricos ventilados posterior a CCC. Con la remoción de filtros seleccionamos 2 artículos que demuestran aumento de Cest y disminución de Rva en sujetos pediátricos en VM, uno comparando con SET, y por grupos de especialistas y no especialistas en respiratorio. Se sugieren estudios primarios para evaluar los efectos de esta intervención en esta población.
Introduction. Congenital heart diseases (CHD) are the second general cause for children death under 1 year. In Chile, approximately 65% CHD need surgery, could was palliative or corrective. In the postoperative period, invasive mechanical ventilation (MV) is frequently used as a life support method, but it is associated with complications. Tracheal suction (SET) is regularly used to remove secretions; however, respiratory chest physiotherapy (KTR) has shown significant improvements in thoraco-pulmonary compliance and airway resistance in other groups of pediatrics and adult's users in MV. Objetive. to compare changes in thoraco-pulmonary compliance and airway resistance in pediatric subjects under mechanical ventilation after congenital heart disease surgery comparing chest physiotherapy and exclusive tracheal suction. Methods. systematic review of studies published in PUBMED, PeDro, Scielo and Google Scholar databases who compares KTR or SET use on changes in ventilatory mechanics in pediatric users under MV after congenital heart disease surgery, limited to English, Spanish and Portuguese languages, excluding user with tracheostomy or extracorporeal membrane of oxygenation. It was use the PRISMA guide to articles selection. A search was carried out, with a total of 397 articles reviewed (English: PubMed = 3, PeDro = 8, Scholar = 383; Spanish: Scholar = 3, Scielo = 0; and Portuguese: Scielo = 0). One extra article was selected from the suggested articles, and 1 article was eliminated due to duplication. By titles and abstracts, 2 articles were selected, but the population did not correspond to heart disease. Results. the final selected articles were 0 articles. By this reason, it were removed: Boolean operator "NOT", and congenital heart disease population. Thus, 2 articles were selected for the final qualitative review where it was compares KTR versus SET, and KTR by specialist and non-specialist. Both articles shown improvement in compliance and resistance until 30 minutes post intervention. The CC population was in a 40 to 60% range in both studies. Conclusions. it was no found articles that demonstrate changes in compliance and resistance in the airway with the use of KTR + SET versus exclusive SET in pediatric users after CCC connected to MV. After filter remotion, we found 2 studies shown improves in increase compliance and reduce resistance in pediatric user in MV, ones comparing with SET, and the other one comparing between specialists in respiratory pediatric physiotherapy and not specialists. It suggests to made primary clinical studies about this intervention in CC population.
ABSTRACT
ABSTRACT Objective: To assess the rib cage expansion and respiratory rate in newborns using an abdominal stabilization band. Methods: The study included 32 newborns of both genders, with gestational age between 35 and 41 weeks. The abdominal stabilization band was used for 15 minutes between the xiphoid process and the anterosuperior iliac crest, with an abdominal contention 0.5cm smaller than the abdominal circumference. The rib cage expansion was evaluated by a breathing transducer (Pneumotrace II™) three minutes before using the band, during the use (15 minutes), and ten minutes after removing the band. The Shapiro-Wilk test verified data normality, and the Wilcoxon test compared the variables considering rib cage expansion and respiratory rate. Significance was set to p<0.05. Results: There was an increase in respiratory rate when comparing before and ten minutes after removing (p=0.008) the abdominal stabilization band, as well as when comparing during its use and ten minutes after its removal (p=0.001). There was also an increase in rib cage expansion when comparing before and during the use of the abdominal stabilization band (p=0.005). Conclusions: The use of the abdominal stabilization band promoted an increase in the rib cage expansion and respiratory rate in the assessed newborns and may be a viable option to improve the respiratory kinematics of this population.
RESUMO Objetivo: Avaliar a expansibilidade torácica e a frequência respiratória em recém-nascidos que fizeram uso de uma faixa de estabilização abdominal. Métodos: O estudo incluiu 32 recém-nascidos de ambos os sexos, com idade gestacional entre 35 e 41 semanas. A faixa de estabilização abdominal foi mantida por 15 minutos entre o processo xifoide e a espinha ilíaca anterossuperior, com contenção abdominal 0,5 cm menor do que a circunferência abdominal. A expansibilidade torácica foi avaliada por um transdutor piezoelétrico (Pneumotrace II™) 3 minutos antes do uso da faixa, durante 15 minutos, e 10 minutos após sua retirada. A normalidade das variáveis foi testada pelo teste de Shapiro-Wilk e a análise comparativa da expansibilidade torácica e da frequência respiratória foi realizada por meio do teste t pareado, considerando-se p<0,05. Resultados: Houve aumento da frequência respiratória quando comparados os tempos antes do uso da faixa e 10 minutos após a retirada (p=0,008), bem como quando comparados os tempos durante o uso e 10 minutos após a retirada da faixa (p=0,001). Houve aumento da expansibilidade torácica quando comparados os tempos antes e durante o uso da faixa (p=0,005). Conclusões: O uso da faixa de estabilização abdominal conferiu aumento da expansibilidade torácica e da frequência respiratória nos recém-nascidos estudados, podendo ser uma opção viável para a melhora da cinemática respiratória dessa população.
ABSTRACT
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.

ABSTRACT
ABSTRACT BACKGROUND: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection. OBJECTIVE: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation. DESIGN AND SETTING: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul. METHODS: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed. RESULTS: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site. CONCLUSION: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.
ABSTRACT
ABSTRACT Introduction: The severe exercise intensity domain can be defined as the range of work rates or speeds over which VO2max can be elicited. Objectives: Our purpose was to determine if critical speed (running analog of critical power) identifies the lower boundary of the severe domain and to identify the upper boundary of the domain. Methods: Twenty-five individuals performed five running tests to exhaustion, each lasting > 2.5 min and < 16 min. The two-parameter speed vs time-to-exhaustion relationship generated values for critical speed and the three-parameter speed vs time-to-reach-VO2max relationship generated values for the threshold speed above which VO2max can be elicited. The relationships were solved to calculate the minimum time needed to elicit VO2max. Results: Critical speed (3.00 ± 0.38 m·s−1) and the threshold speed above which VO2max can be elicited (2.99 ± 0.37 m·s−1) were correlated (r = 0.83, p < 0.01) and did not differ (p = 0.70), confirming critical speed as the lower boundary of the severe domain. The minimum time needed to elicit VO2max (103 ± 7 s) and the associated highest speed at which VO2max can be elicited (4.98 ± 0.52 m·s−1) identified the upper boundary of the severe domain for these participants. Conclusion: The critical power concept, which requires no metabolic measurements, can be used to identify the lowest speed at which VO2max can be elicited. With addition of metabolic measurements, mathematical modeling can also identify the highest speed and shortest exercise duration at which VO2max can be elicited. Evidence Level I; Validating cohort study with good reference standards.
RESUMEN Introducción: El dominio de la intensidad del ejercicio severo se puede definir como el rango de ritmos o velocidades de trabajo sobre las que se puede obtener el VO2max. Objetivos: Nuestro propósito fue determinar si la velocidad crítica (funcionamiento analógico de potencia crítica) identifica el límite inferior del dominio severo e identificar el límite superior del dominio. Métodos: Veinticinco personas realizaron cinco pruebas de carrera hasta el agotamiento, cada una con una duración de > 2,5 min y <16 min. La relación de dos parámetros de velocidad frente a tiempo de agotamiento generó valores para la velocidad crítica y la relación de tres parámetros de velocidad frente a tiempo de alcance de VO2max generó valores para la velocidad umbral por encima del cual se puede obtener el VO2max. Las relaciones se resolvieron para calcular el tiempo mínimo necesario para obtener el VO2max. Resultados: La velocidad crítica (3,00 ± 0,38 m·s−1) y la velocidad umbral por encima de la cual se puede obtener el VO2max (2,99 ± 0,37 m·s−1) se correlacionaron (r = 0,83, p < 0,01) y no difirieron (p = 0,70), lo que confirma la velocidad crítica como el límite inferior del dominio severo. El tiempo mínimo necesario para obtener el VO2max (103 ± 7 s) y la velocidad más alta asociada a la que se puede obtener el VO2max (4,98 ± 0,52 m·s−1) identificaron el límite superior del dominio severo para estos participantes. Conclusión: El concepto de potencia crítica, que no requiere mediciones metabólicas, se puede utilizar para identificar la velocidad más baja a la que se puede obtener el VO2max. Con la adición de mediciones metabólicas, el modelado matemático también puede identificar la velocidad más alta y la duración más corta del ejercicio a la que se puede obtener VO2max. Nivel de Evidencia I; Estudio de cohortes con alto estándar de referencia.
RESUMO Introdução: O domínio de intensidade de exercício severo pode ser definido como a faixa de taxas de trabalho ou velocidades sobre as quais o VO2max pode ser obtido. Objetivos: Nosso propósito foi determinar se a velocidade crítica (execução analógica da potência crítica) identifica o limite inferior do domínio severo e identificar o limite superior do domínio. Métodos: Vinte e cinco indivíduos realizaram cinco testes de corrida até a exaustão, cada um com duração > 2,5 min e < 16 min. A relação velocidade de dois parâmetros contra tempo até a exaustão gerou valores para a velocidade crítica e a relação velocidade de três parâmetros contra tempo para alcançar o VO2max valores gerados para a velocidade limite acima da qual o VO2max pode ser obtido. As relações foram resolvidas para calcular o tempo mínimo necessário para eliciar o VO2max. Resultados: A velocidade crítica (3,00 ± 0,38 m·s−1) e a velocidade limite acima da qual o VO2max pode ser eliciado (2,99 ± 0,37 m·s−1) foram correlacionadas (r = 0,83, p < 0,01) e não diferiram (p = 0,70), confirmando a velocidade crítica como o limite inferior do domínio grave. O tempo mínimo necessário para eliciar o VO2max (103 ± 7 s) e a maior velocidade associada na qual o VO2max pode ser eliciado (4,98 ± 0,52 m·s−1) identificou o limite superior do domínio severo para esses participantes. Conclusão: O conceito de potência crítica, que não requer medidas metabólicas, pode ser usado para identificar a velocidade mais baixa em que o VO2max pode ser eliciado. Com a adição de medidas metabólicas, a modelagem matemática também pode identificar a velocidade mais alta e a duração mais curta do exercício em que o VO2max pode ser obtido. Nível de Evidência I; Estudo de coorte com alto padrão de referência.
ABSTRACT
Introduction: during the global COVID-19 pandemic, non-invasive ventilation has become a widely utilized method for treating patients experiencing acute respiratory failure. Noninvasive pressure ventilation is frequently employed as a standard approach for managing acute respiratory failure resulting from COVID-19 pneumonia, as opposed to invasive ventilation methods. However, there is a lack of research on its effectiveness. Therefore, this study aimed to determine the risk of mortality among COVID-19 patients receiving non-invasive ventilation. Methods: a multi-centric retrospective cross sectional study was conducted on the records of 402 patients at the Eka Kotebe COVID-19 Center, St. Peter COVID-19 Care Center, and Millennium COVID-19 Treatment Center. The systematic random selection technique was employed in order to select the study unit, and data was extracted from patient charts using a pretested method and validated before being entered into Epi-data Manager 4.6 versions. Descriptive, bivariate, and multivariable analyses were performed using binary logistic regression in SPSS 25. In the multivariate logistic regression, a predictor variable was considered to have a significant connection if its p-value was less than 0.05 at a 95% confidence level. Results: four hundred and two patient records were reviewed during the study period and showed the mean patient´s age was 62.6 years, with male predominance. It revealed that 11.7% [CI: 8.7-15.2] of COVID-19 patients who received non-invasive positive pressure ventilation died, as being critical for COVID-19 patients was a main cause of noninvasive initiation. Patients over the age of 60 were more likely to die among those who received noninvasive ventilation for COVID-19 [AOR = 5.4 95% CI 1.32, 23.1]. Conversely, patients without diabetes were less likely to die [AOR = 0.23 95% CI 0.11, 0.48]. Moreover, patients with a tidal volume greater than 500 ml were more likely to pass away [AOR =2.2 95% CI 1.11,4.43], as were those who were on non-invasive ventilation (NIV) for more than 8 days [AOR = 0.24 95% CI.08, 0.81]. Conclusion: the significance of patients who were given non-invasive ventilators ended up dying. Age, diabetes, and high tidal volumes are linked to a higher risk of death. Non-invasive ventilation for over eight days showed a protective effect. Removing factors that caused NIV and ventilated COVID-19 patients' deaths may reduce mortality.

Introducción: la pandemia de COVID-19 produjo una alta mortalidad en el mundo. Sin embargo, las presentaciones más críticas de la enfermedad han sido poco caracterizadas en nuestra región. Objetivo: estudiar la presentación clínica, evolución y mortalidad en pacientes ingresados en la unidad de medicina intensiva de un centro COVID-19 de referencia. Pacientes y método: estudio clínico, prospectivo, observacional de SARS-CoV-2 durante las primeras etapas de la pandemia en Uruguay. Se definió mortalidad en unidad de cuidados intensivos (UCI) como desenlace primario. Resultados: en 274 pacientes, la edad mediana fue de 65 años (IQR 54-73), el sexo masculino representó el 57% y el índice de Charlson tuvo una mediana de 3 (IQR 2-5). La mortalidad en UCI fue 59,9%. Las principales causas de muerte fueron: hipoxemia refractaria, disfunción orgánica múltiple y shock refractario. La edad (Odds Ratio (OR) = 1,06; IC de 95% 1,03 - 1,09), ocupación de camas (OR = 1,04, IC 95%: 1,02 - 1,07), sexo masculino (OR = 2,14, IC 95%: 0,93 - 5,06), ventilación mecánica invasiva (OR = 51,7, IC 95%: 16,5 - 208,6), coinfección al ingreso (OR = 2,34, IC 95%: 0,88 - 6,77) y enfermedad renal crónica previa (OR = 13,1, IC 95%: 2,29 - 129,2) fueron predictores independientes de mortalidad. La primera ola de la pandemia se produjo por la circulación de las variantes P.6 y P.1 del coronavirus, en una población con muy bajo porcentaje de vacunación (8%). Conclusiones: estos resultados en pacientes críticos aportan una descripción detallada del impacto de la pandemia por SARS-CoV-2 en un centro de referencia y constituyen una base para enfrentar futuros eventos epidémicos.
Introduction: COVID-19 has caused high mortality worldwide. However, the most critical presentations of the disease have been poorly characterized in our region. Objective: to study the clinical presentation, progression, and mortality in patients admitted to the Intensive Care Unit (ICU) of a COVID-19 Reference Center. Patients and methods: clinical, prospective, observational study of SARS-CoV-2 during the early stages of the pandemic in Uruguay. ICU mortality was defined as the primary outcome. Results: in 274 patients, the median age was 65 years (IQR 54-73), male gender accounted for 57%, and the Charlson Index was 3 (IQR 2-5). ICU mortality was 59.9%. The main causes of death were refractory hypoxemia, multiple organ dysfunction, and refractory shock. Age (Odds Ratio (OR) = 1.06; 95% CI 1.03 - 1.09), bed occupancy (OR= 1.04, 95% CI: 1.02 -1.07), male gender (OR= 2.14, 95% CI 0.93 - 5.06), invasive mechanical ventilation (OR= 51.7, 95% CI 16.5 - 208.6), coinfection at admission (OR= 2.34, 95% CI 0.88 - 6.77), and pre-existing chronic kidney disease (OR= 13.1, 95% CI 2.29 - 129.2) were independent predictors of mortality. The first wave of the pandemic was driven by the circulation of the P.6 and P.1 variants of the coronavirus in a population with a very low vaccination percentage (8%). Conclusions: these results in critical patients provide a detailed description of the impact of the SARS-CoV-2 pandemic in a reference center and serve as a foundation for addressing future epidemic events.

A primeira onda da pandemia foi impulsionada pela circulação das variantes P.6 e P.1 do SARS-CoV-2 em uma população com uma taxa de vacinação muito baixa (8%). Conclusões: esses resultados em pacientes críticos fornecem uma descrição detalhada do impacto da pandemia SARS-CoV-2 em um Centro de Referência e constituem uma base para o enfrentamento de futuros eventos epidêmicos.
ABSTRACT
Introducción. La ventilación de alta frecuencia (VAF) es utilizada en pacientes graves neonatales con un uso cercano al 10% del total de usuarios en ventilación mecánica (VM). Actualmente estos equipos miden volumen corriente de manera precisa, continua y rutinaria, sin embargo no hay estimaciones del comportamiento mecánico del sistema respiratorio del usuario, como lo es la distensibilidad toracopulmonar, durante el ciclo ventilatorio que sean reportadas por las pantallas de los equipos. Objetivo. Estimar distensibilidad dinámica toracopulmonar en modelos neonatales de VAF. Métodos. Estudio cuantitativo, observacional, descriptivo, y "wench work", donde se midió distensibilidad en VM convencional y volumen corriente (Vt) en VAF con equipo Acutronics Fabian® por 4 evaluadores independientes, en 5 tipos de pulmón de ensayo y bajo diferentes escenarios de parámetros de VAF con ajustes de presión media de la vía aérea (PMVA), amplitud, frecuencia respiratoria, tiempo inspiratorio, volumen garantizado, y tipo de circuito. Mediante suavización de regresiones locales por estimación mínima cuadrática (LOWESS) y análisis de regresión multivariada se obtuvieron los valores asociados a distensibilidad, con los que se construyeron ecuaciones de estimación de distensibilidad en VAF. Resultados. Se realizaron en total 46080 mediciones, con correlación intra e interevaluador > 0.99. La distensibilidad mediana (percentil 25; 75) de los 5 modelos pulmonares fue de 0.455 (0.3; 0.98). Se asociaron a distensibilidad, mediante modelos de regresión lineal múltiple de manera significativa, todas las variables evaluadas, salvo PMVA. Se establecieron asociaciones multivariantes crudas (R2=.311), de distensibilidad predicha por LOWESS (R2=.744) y distensibilidad predicha y variables independientes predichas por regresión lineal simple (R2=.973). Conclusiones. La distensibilidad en VAF esta determinada en pulmones de ensayos por los parámetros programados de: tipo de circuito, uso de volumen garantizado, tiempo inspiratorio, frecuencia respiratoria y amplitud, además del Vt medido. Se reporta ecuación explicativa de distensibilidad en VAF.
Background. Background: High frequency mechanical ventilation (HFV) is used in severe neonatal subjects nearly 10% of total mechanically ventilated (MV) users. Currently, this MV's mode allow to measure tidal volumen in an accurately, continuous and routinarie way in HFV, however there are non estimation to assess mechanical behavior of respiratory system during ventilatory cycle, like thoraco-pulmonary compliance, who be report in the equipment display. Objetive. To estimate thoraco-pulmonary compliance in artificial neonatal lung models in HFV. Methods. Quantitative, observational, descriptive, and wench work study, where distensibility was measured in conventional MV and tidal volume (TV) in HFV with Acutronics Fabian® equipment by 4 independent evaluators, in 5 types of test lung and under different scenarios of HFV parameters with adjustments of mean airway pressure (MAP), amplitude, respiratory rate, inspiratory time, guaranteed volume, and type of circuit. By smoothing local regressions by least quadratic estimation (LOWESS) and multivariate regression analysis, the values associated with distensibility were obtained, with this measures, equations for estimating compliance in VAF were constructed. Results. A total of 46080 measurements were made, with intra and inter-evaluator correlation coefficent > 0.99. The median compliance (25th percentile; 75) of the 5 lung models was 0.455 (0.3; 0.98). All variables evaluated, except MAP, were associated with compliance, by means of multiple linear regression models. Crude multivariate associations (R2 = .311), predicted compliance by LOWESS (R2 = .744) and predicted compliance and independent variables predicted by simple linear regression (R2 = .973) were established to estimate thoraco-pulmonary compliance. Conclusions. Compliance in VAF is determined in test lungs by the programmed parameters of: type of circuit, use of guaranteed volume, inspiratory time, respiratory frequency and amplitude, in addition to the measured Vt. An explanatory equation for distensibility in VAF is reported.
ABSTRACT
Background and Objectives: several patients with COVID-19 require hospital admission due to severe respiratory complications and undergo intensive care with mechanical ventilation (MV) support. Associated with this situation, there is an increase in fungal co-infections, which has a negative impact on the outcome of COVID-19. In this regard, this study intended to compare Candida spp. incidence in the respiratory tract of patients admitted in the COVID and General Intensive Care Units (ICU) at a teaching hospital in 2021. Methods: the results of protected tracheal aspirate samples from 556 patients admitted to the COVID ICU and 260 to General ICU as well as the respective records. Results: of the patients analyzed, 38 revealed a positive sample for Candida in the COVID ICU and 10 in the General ICU, with an incidence of 68.3/1000 and 38.5/1000, respectively. Males were predominant in both wards. The most affected age group was the population over 60 years old, and the average hospital admission for the COVID ICU was 22.1 years, and for the General ICU, 24.2. Conclusion: Candida albicans was the most frequently isolated species, and the mortality rate in patients positive for Candida was higher in patients with COVID-19 compared to patients in the General ICU, suggesting that patients infected with SARS-CoV-2, admitted to the ICU under MV, are more predisposed to colonization by Candida spp., which can have a fatal outcome in these patients.(AU)
Justificativa e objetivos: muitos pacientes com COVID-19 necessitam de hospitalização devido às complicações respiratórias graves, e são submetidos a cuidados intensivos com suporte de ventilação mecânica (VM). Associado a esse quadro, verifica-se o aumento de coinfecções fúngicas, que tem impacto negativo no desfecho da COVID-19. Nesse sentido, este estudo pretendeu comparar a incidência de Candida spp. no trato respiratório de pacientes internados nas Unidades de Terapia Intensiva (UTI) COVID e Geral em um hospital escola em 2021. Métodos: foram avaliados os resultados de amostras de aspirado traqueal protegido provenientes de 556 pacientes internados na UTI COVID e 260 na UTI Geral, bem como os respectivos prontuários. Resultados: dos pacientes analisados, 38 revelaram amostra positiva para Candida na UTI COVID e 10 na UTI Geral, com incidência de 68,3/1000 e 38,5/1000, respectivamente. O sexo masculino foi predominante em ambas as alas. A faixa etária mais acometida foi a população acima de 60 anos, e a média de internação para a UTI COVID foi de 22,1 anos, e para a UTI Geral, 24,2. Conclusão: Candida albicans foi a espécie isolada com maior frequência, e a taxa de mortalidade em pacientes com positivos para Candida foi maior em pacientes com COVID-19 em relação aos pacientes da UTI Geral, sugerindo que pacientes infectados com SARS-CoV-2, internados em UTI sob VM, são mais predispostos à colonização por Candida spp., que pode ter um desfecho fatal nesses pacientes.(AU)

Asociado a esta situación, hay un aumento de las coinfecciones fúngicas, lo que repercute negativamente en el desenlace de la COVID-19. En este sentido, este estudio pretendió comparar la incidencia de Candida spp. en el tracto respiratorio de pacientes ingresados en las Unidades de Cuidados Intensivos (UCI) COVID y General de un hospital escuela en 2021. Métodos: los resultados de muestras de aspirado traqueal protegidas de 556 pacientes ingresados en la UCI COVID y 260 en el UCI General, así como los respectivos registros. Resultados: de los pacientes analizados, 38 presentaron muestra positiva a Candida en UCI COVID y 10 en UCI General, con una incidencia de 68,3/1000 y 38,5/1000, respectivamente. Los machos predominaban en ambas alas. El grupo de edad más afectado fue la población mayor de 60 años, y la hospitalización promedio en la UCI COVID fue de 22,1 años, y en la UCI General, de 24,2. Conclusiones: Candida albicans fue la especie aislada con mayor frecuencia, y la tasa de mortalidad en pacientes positivos para Candida fue mayor en pacientes con COVID-19 en comparación con los pacientes en la UCI General, lo que sugiere que los pacientes infectados con SARS-CoV-2, ingresados en la UCI bajo VM, están más predispuestos a la colonización por Candida spp., lo que puede tener un desenlace fatal en estos pacientes.(AU)

Resumen: Desde el inicio de la pandemia por COVID-19, dentro de las complicaciones más frecuentes de esta infección se encuentran la neumonía y el síndrome de dificultad respiratoria aguda. La hipoxemia y el aumento del trabajo respiratorio son determinantes para adoptar diversas estrategias terapéuticas de oxigenación no invasiva en pacientes con COVID-19. Es importante conocer y describir las diferentes modalidades de oxigenoterapia no invasiva, con la finalidad de preservar la oxigenación y un adecuado trabajo respiratorio, las estrategias descritas en la literatura abarcan: cánulas nasales convencionales, cánulas nasales de alto flujo y ventilación mecánica no invasiva, aunado a otras medidas de soporte como posición prono, administración de esquemas con esteroide, inmunomoduladores y óxido nítrico inhalado. Las estrategias no invasivas de oxigenación por diferentes métodos son herramientas indispensables para el tratamiento de pacientes con neumonía por COVID-19 moderada-grave. Es necesario evaluar el dispositivo a emplear, ya que esta enfermedad tiene características heterogéneas de acuerdo con gravedad y el tiempo de evolución.
Abstract: Since the start of the COVID-19 pandemic, the most frequent complications of this infection include pneumonia and Acute Respiratory Distress Syndrome. Hypoxemia and increased work of breathing are determining factors in adopting various non-invasive oxygenation therapeutic strategies in patients with COVID-19. It is important to know and describe the different modalities of non-invasive oxygen therapy, in order to preserve oxygenation and adequate respiratory work, the strategies described in the literature include: conventional nasal cannulas, high-flow nasal cannulas and non-invasive mechanical ventilation coupled with other support measures such as prone position, administration of schemes with steroids, immunomodulators and inhaled nitric oxide. Non-invasive oxygenation strategies by different methods are essential tools for the treatment of patients with moderate-severe COVID-19 pneumonia. It is necessary to evaluate the device to be used, since this disease has heterogeneous characteristics according to severity and time of evolution.
ABSTRACT
Abstract Background: Asthma is a common cause of admission to the pediatric intensive care unit (PICU). We described and analyzed the therapies applied to children admitted to a tertiary PICU because of asthma. Later, we evaluated high-flow nasal cannula (HFNC) use in these patients and compared their evolution and complications with those who received non-invasive ventilation. Methods: We conducted a prospective observational study (October 2017-October 2019). Collected data: epidemiological, clinical, respiratory support therapy needed, complementary tests, and PICU and hospital stay. Patients were divided into three groups: (1) only HFNC; (2) HFNC and non-invasive mechanical ventilation (NIMV); and (3) only NIMV. Results: Seventy-six patients were included (39 female). The median age was 2 years and 1 month. The median pulmonary score was 5. The median PICU stay was 3 days, and the hospital stay was 6 days. Children with HNFC only (56/76) had fewer PICU days (p = 0.025) and did not require NIMV (6/76). Children with HFNC had a higher oxygen saturation/fraction of inspired oxygen ratio ratio (p = 0.025) and lower PCO2 (p = 0.032). In the group receiving both therapies (14/76), NIMV was used first in all cases. No epidemiologic or clinical differences were found among groups. Conclusion: HFNC was a safe approach that did not increase the number of PICU or hospital days. On admission, normal initial blood gases and the absence of high oxygen requirements were useful in selecting responders to HFNC. Further randomized and multicenter clinical trials are needed to verify these data.
Resumen Introducción: El asma es una causa frecuente de ingreso en la unidad de cuidados intensivos pediátricos (UCIP). En este, cuadro el uso de cánula nasal de alto flujo (CNAF) se ha visto extendido. En este trabajo se describe el tratamiento global en la UCIP ante el ingreso por asma en un hospital monográfico pediátrico y se evalúa la respuesta al uso de la CNAF, comparando la evolución de los pacientes con aquellos que recibieron ventilación no invasiva (VNI). Métodos: Se llevó a cabo un estudio observacional prospectivo (de octubre del 2017 a octubre del 2019). Se describieron epidemiología, clínica, tratamiento y soporte respiratorio. Para la comparación se crearon tres grupos de pacientes: 1) solo CNAF; 2) CNAF y VNI; y 3) solo VNI. Resultados: Se incluyeron 76 pacientes. La mediana de edad fue de dos años y un mes; la mediana de índice pulmonar fue 5. La mediana de ingreso en UCIP fue de tres días y de ingreso hospitalario, seis días. Los niños con solo CNAF (56/76) mostraron menos días de UCIP (p = 0.025) y no requirieron VNI (6/76). También mostraron mayor SatO2/FiO2 (saturación de oxígeno/fracción de oxígeno inspirado) (p = 0.025) y menor nivel de PCO2 (presión parcial de CO2) (p = 0.032). La VNI se utilizó primero siempre en el grupo que recibió ambas modalidades (14/76). No se encontraron diferencias epidemiológicas o clínicas entre grupos. Conclusiones: En nuestra serie, el uso de CNAF no aumentó los días de ingreso en la UCIP ni de hospital. Tampoco requirió cambio a VNI. Al ingreso, una gasometría normal y bajo requerimiento de oxígeno permitieron seleccionar a los pacientes respondedores. Se necesitan más ensayos multicéntricos clínicos aleatorizados para verificar estos datos.
ABSTRACT
ABSTRACT Objective: To describe, with a larger number of patients in a real-world scenario following routine implementation, intensivist-led ultrasound-guided percutaneous dilational tracheostomy and the possible risks and complications of the procedure not identified in clinical trials. Methods: This was a phase IV cohort study of patients admitted to three intensive care units of a quaternary academic hospital who underwent intensivist-led ultrasound-guided percutaneous tracheostomy in Brazil from September 2017 to December 2021. Results: There were 4,810 intensive care unit admissions during the study period; 2,084 patients received mechanical ventilation, and 287 underwent tracheostomy, 227 of which were performed at bedside by the intensive care team. The main reason for intensive care unit admission was trauma, and for perform a tracheostomy it was a neurological impairment or an inability to protect the airways. The median time from intubation to tracheostomy was 14 days. Intensive care residents performed 76% of the procedures. At least one complication occurred in 29.5% of the procedures, the most common being hemodynamic instability and extubation during the procedure, with only 3 serious complications. The intensive care unit mortality was 29.1%, and the hospital mortality was 43.6%. Conclusion: Intensivist-led ultrasound-guided percutaneous tracheostomy is feasible out of a clinical trial context with outcomes and complications comparable to those in the literature. Intensivists can acquire this competence during their training but should be aware of potential complications to enhance procedural safety.
RESUMO Objetivo: Descrever, com um número maior de pacientes em um cenário do mundo real após a implementação rotineira, a traqueostomia percutânea guiada por ultrassom conduzida por intensivistas e os possíveis riscos e complicações do procedimento não identificados em estudos clínicos. Métodos: Trata-se de estudo de coorte de fase IV de pacientes internados em três unidades de terapia intensiva de um hospital acadêmico quaternário que foram submetidos a traqueostomia percutânea guiada por ultrassom conduzida por intensivistas no Brasil de setembro de 2017 a dezembro de 2021. Resultados: Entre as 4.810 admissões na unidade de terapia intensiva durante o período do estudo, 2.084 pacientes receberam ventilação mecânica, e 287 foram submetidos a traqueostomia, 227 das quais foram realizadas à beira do leito pela equipe de terapia intensiva. O principal motivo para a admissão na unidade de terapia intensiva foi trauma, e para a realização de uma traqueostomia foi comprometimento neurológico ou incapacidade de proteger as vias aéreas. O tempo médio entre a intubação e a traqueostomia foi de 14 dias. Residentes de terapia intensiva realizaram 76% dos procedimentos. Ao menos uma complicação ocorreu em 29,5% dos procedimentos, sendo instabilidade hemodinâmica e extubação durante o procedimento as complicações mais comuns, com apenas três complicações graves. A mortalidade na unidade de terapia intensiva foi de 29,1%, e a mortalidade hospitalar foi de 43,6%. Conclusão: A traqueostomia percutânea guiada por ultrassom conduzida por intensivistas é viável fora do contexto de um estudo clínico com resultados e complicações comparáveis aos da literatura. Os intensivistas podem adquirir essa competência durante seu treinamento, mas devem estar cientes das possíveis complicações para aumentar a segurança do procedimento.
ABSTRACT
Objetivo: realizar uma revisão integrativa a respeito da função pulmonar e da força muscular respiratória nos músicos de instrumentos de sopro. A relação da função respiratória com a utilização de instrumentos musicais de sopro é uma área do conhecimento ainda pouco explorada. Métodos: Realizada a revisão bibliográfica nas bases de dados MEDLINE, Embase, Cochrane, PeDro, BVS, Scopus, Web of Science e SciELO, através da combinação das palavras-chave "respiratory function test", "wind instrument", musician, "pulmonary ventilation" e "Lung Function Test". Resultados: Inicialmente foram encontrados 108 artigos, sendo que destes foram selecionados 11, totalizando 596 músicos instrumentistas de sopro, que fizeram parte dos grupos de estudo. Na maioria dos estudos os músicos apresentaram valores menores do volume expirado no primeiro segundo (VEF1) e da capacidade vital forçada (CVF) na espirometria que o grupo controle. No entanto, sem diferença quanto a relação VEF1/CVF. Assim como não há diferença na força muscular respiratória ou relação com doenças respiratórias. Conclusão: Os estudos atuais a respeito da consequência do instrumento de sopro em indivíduos não são capazes de evidenciar impactos positivos ou negativos na saúde respiratória desta população.
Objective: To conduct an integrative review of lung function and respiratory muscle strength in wind instrument musicians. The relationship between respiratory function and the use of wind musical instruments is an area of knowledge that has not been extensively explored. Methods: A bibliographic review was carried out in the MEDLINE, Embase, Cochrane, PeDro, BVS, Scopus, Web of Science, and SciELO databases by combining the keywords "respiratory function test", "wind instrument", musician, "pulmonary ventilation" and "Lung Function Test". Results: Initially, 108 articles were found, of which 11 were selected, totaling 596 wind instrumentalists who were part of the study groups. In most studies, musicians showed lower values of expired volume in one second (FEV1) and forced vital capacity (FVC) in spirometry than in the control group. However, there was no difference regarding the FEV1/FVC ratio, just as there was no difference in respiratory muscle strength or relationship with respiratory diseases. Conclusion: Current studies regarding the effect of wind instruments on individuals are unable to show positive or negative impacts on the respiratory health of this population.

Métodos. Estudio tipo antes-después, no controlado, en la UCIP de un hospital pediátrico. Se desarrolló en 3 etapas: preintervención de diagnóstico situacional (de abril a septiembre de 2019), intervención y posintervención de implementación del protocolo de sedoanalgesia, educación sobre uso y monitorización de adherencia y su impacto (de octubre de 2019 a octubre de 2021). Resultados. Ingresaron al estudio 99 y 92 pacientes en las etapas pre- y posintervención, respectivamente. Presentaron mayor gravedad, menor edad y peso en el período preintervención. En la comparación de grupos, luego de ajustar por gravedad y edad, en la etapa posintervención se reportó una reducción en los días de uso de opioides en infusión continua (6 ± 5,2 vs. 7,6 ± 5,8; p = 0,018) y los días de uso de benzodiacepinas en infusión continua (3,3 ± 3,5 vs. 7,6 ± 6,8; p = 0,001). No se observaron diferencias significativas en los días de AVM y en los días totales de uso de benzodiacepinas. Conclusión. La implementación de un protocolo de sedoanalgesia permitió reducir el uso de fármacos en infusión continua.
Introduction. Adequate sedation and analgesia is essential in the management of patients requiring mechanical ventilation (MV). The implementation of protocols and their monitoring is recommended; mixed results on adherence and impact have been reported. Objectives. To assess the impact of the implementation of a sedation and analgesia protocol on the use of benzodiazepines, opioids, and evolution in the pediatric intensive care unit (PICU) in patients requiring MV for more than 72 hours. Methods. Before-and-after, uncontrolled study in the PICU of a children's hospital. The study was developed in 3 stages: pre-intervention for situational diagnosis (from April to September 2019), intervention, and post-intervention for implementation of a sedation and analgesia protocol, education on use, and monitoring of adherence and impact (from October 2019 to October 2021). Results. A total of 99 and 92 patients were included in the study in the pre- and post-intervention stages, respectively. Patients had a more severe condition, were younger, and had a lower weight in the preintervention period. After adjusting for severity and age, the group comparison in the post-intervention stage showed a reduction in days of continuous infusion of opioids (6 ± 5.2 versus 7.65.8, p = 0.018) and days of continuous infusion of benzodiazepines (3.3 ± 3.5 versus 7.6 ± 6.8, p = 0.001). No significant differences were observed in days of MV and total days of benzodiazepine use. Conclusion. The implementation of a sedation and analgesia protocol resulted in a reduction in the use of continuous infusion of drugs.

Evaluar la eficacia del dispositivo artesanal de asistencia respiratoria no invasivo de administración de presión positiva continua en las vías respiratorias (CPAP) Wayrachi en comparación con la cánula de alto flujo comercial (CAF) para el tratamiento de pacientes con SARS-CoV-2. Estudio realizado en el Hospital Honorio Delgado Espinoza de Arequipa (Hospital COVID-MINSA Arequipa). Se evaluó a las historias clínicas de pacientes con SARS-CoV-2, de severidad moderada o grave que requerían asistencia respiratoria no invasiva, hospitalizados en el servicio de medicina interna durante la segunda ola de COVID en el Perú. Se realizó un análisis de supervivencia considerando los días a la muerte comparando al Wayrachi con la CAF. Se exploró el efecto de las variables sobre la muerte mediante una regresión de Cox. Resultados: Se evaluaron 114 pacientes tratados con Wayrachi (56,44 %) y 88 con CAF (43,5 %), observándose una frecuencia de muerte de 34,2 % y 34,1 % respectivamente. Al comparar la frecuencia de muerte, o su sobrevida, en ambos manejos no se observó una diferencia significativa (p=0,986 y p=0,928), esto se mantuvo en el modelo multivariado. El CPAP Wayrachi tuvo resultados similares a los presentados por el equipo CAF comercial lo que lo indica como una opción eficaz para el manejo de pacientes COVID que requieran soporte respiratorio no invasivo.
To evaluate the efficacy of the Wayrachi continuous positive airway pressure (CPAP) non-invasive respiratory support device compared to the commercial high-flow cannula (CAF) for the treatment of patients with SARS-CoV-2. Study carried out at the Honorio Delgado Espinoza Hospital in Arequipa (Hospital COVID-MINSA Arequipa). The medical records of patients with SARS-CoV-2, of moderate or severe severity, who required non-invasive respiratory assistance, hospitalized in the internal medicine service during the 2nd wave of COVID in Peru, were evaluated. A survival analysis was performed considering days to death comparing Wayrachi with CAF. The effect of variables on death was explored using Cox regression. Results: 114 patients treated with Wayrachi (56.44%) and 88 with CAF (43.5%) were evaluated, observing a frequency of death of 34.2% and 34.1%, respectively. When comparing the frequency of death, or its survival, in both managements, no significant difference was observed (p=0.986 and p=0.928), this was maintained in the multivariate model. The Wayrachi CPAP had similar results to those presented by the commercial CAF equipment, which indicates it as an effective option for the management of COVID patients who require non-invasive respiratory support.

Introducción: El síndrome de dificultad respiratoria aguda producido por la COVID-19 provoca alteraciones en el intercambio de oxígeno y la excreción de dióxido de carbono con consecuencias neurológicas. Objetivo: Describir las implicaciones del oxígeno y el dióxido de carbono sobre la dinámica cerebral durante el tratamiento ventilatorio del síndrome de dificultad respiratoria aguda en el accidente cerebrovascular. Métodos: Se realizó una búsqueda en bases referenciales como: PubMed/Medline, SciELO, Google Académico y BVS Cuba. Los términos incluidos fueron brain-lung crosstalk, ARDS, mechanical ventilation, COVID-19 related stroke, ARDS related stroke y su traducción al español. Fueron referenciados libros de neurointensivismo y ventilación mecánica artificial. El período de búsqueda incluyó los últimos 20 años. Se seleccionaron 46 bibliografías que cumplieron con los criterios de selección. Resultados: Se ha descrito que los niveles de oxígeno y dióxido de carbono participan en la neurorregulación vascular en pacientes con daño cerebral. Algunas alteraciones alusivas son la vasodilatación cerebral refleja o efectos vasoconstrictores con reducción de la presión de perfusión cerebral. Como consecuencia aumenta la presión intracraneal y aparecen afectaciones neurocognitivas, isquemia cerebral tardía o herniación del tronco encefálico. Conclusiones: El control de la oxigenación y la excreción de dióxido de carbono resultaron cruciales para mantener la homeostasis neuronal, evita la disminución de la presión de perfusión cerebral y el aumento de la presión intracraneal. Se sugiere evitar la hipoxemia e hiperoxemia, limitar o eludir la hipercapnia y usar hiperventilación hipocápnica solo en condiciones de herniación del tallo encefálico.
Introduction: The acute respiratory distress syndrome produced by COVID-19 causes alterations in the exchange of oxygen and the excretion of carbon dioxide with neurological consequences. Objective: To describe the implications of oxygen and carbon dioxide on brain dynamics during ventilatory treatment of acute respiratory distress syndrome in stroke. Methods: A search was carried out in referential bases such as PubMed/Medline, SciELO, Google Scholar and VHL Cuba. The terms included were brain-lung crosstalk, ARDS, mechanical ventilation, COVID-19 related stroke, ARDS related stroke and their translation into Spanish. Books on neurointensive care and artificial mechanical ventilation were referenced. The search period included the last 20 years. Forty six bibliographies that met the selection criteria were selected. Results: Oxygen and carbon dioxide levels have been described to participate in vascular neuroregulation in patients with brain damage. Some allusive alterations are reflex cerebral vasodilatation or vasoconstrictor effects with reduced cerebral perfusion pressure. As a consequence, intracranial pressure increases and neurocognitive impairments, delayed cerebral ischemia or brainstem herniation appear. Conclusions: The control of oxygenation and the excretion of carbon dioxide were crucial to maintain neuronal homeostasis, avoiding the decrease in cerebral perfusion pressure and the increase in intracranial pressure. It is suggested to avoid hypoxemia and hyperoxemia, limit or avoid hypercapnia, and use hypocapnic hyperventilation only in conditions of brainstem herniation.
ABSTRACT
Objectives: To document the adverse cardiorespiratory events following first routine immunization in preterm neonates. Methods: We retrieved records of neonates with gestational age ?30 weeks, and included those who developed cardiorespiratory events after first vaccines before discharge. Our Unit’s protocol is to administer Bacillus Calmette-Guerin (BCG), hepatitis B vaccine to those discharged at <8 weeks postnatal age. Hexavalent, BCG, pneumococcal vaccine and rotavirus vaccines are given at 8 weeks of age, if hospital stay is predicted to be longer. Unit compliance to vaccination administration at appropriate ages were also measured. Results: Data of 161 neonates ?30 weeks (17.4% <27 week) who completed care in the unit was studied. Cardio-respiratory adverse events were reported in 21(13.7%). None of these required initiation of invasive ventilation. High flow nasal cannula therapy and caffeine restart were required for these events in 14 (9.3%) and 6 (3.9%) neonates, respectively. Lower gestational age, bronchopulmonary dysplasia and sepsis were significant risk factors on univariate analysis. On multivariate analysis, continued need for respiratory support at 4 weeks of age (P=aOR 14.5 (95% CI 5-59.1) was the only independent risk factor for post-vaccination cardiorespiratory adverse events. Of 38 who were not vaccinated at recommended ages by unit policy, 25 were missed opportunities, the rest were deemed unstable for vaccinations at that age by the clinical team. Conclusion: Adverse cardiorespiratory events were uncommon after first vaccinations in very preterm neonates. Administering vaccines in this group before discharge would allow monitoring for these events, especially for those who require long-term respiratory support.
ABSTRACT
Background: Previous studies have shown that hepatic fibrosis indices and rates can be used to predict cardiovascular mortality and morbidity. Our aim with this study was to investigate the effect of aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio and fibrosis?4 (FIB?4) index calculated with ALT, AST, and platelet biomarkers, which are simple, fast, and relatively inexpensive and were used in previous studies to predict cardiovascular disease prognosis, on the prediction of postoperative morbidity and early mortality after mitral valve replacement (MVR) surgery. Methods: By scanning the hospital electronic health record system, 116 patients who underwent isolated MVR or MVR + tricuspid valve intervention were identified from 178 patients who underwent MVR with the standard sternotomy procedure between 2011 and 2021. The study was completed with 81 of these patients. Patients were divided into AST/ALT <2 (Group 1) and >2 (Group 2). In addition, the same patients were divided into FIB?4 index <3.25 (Group 3) and >3.25 (Group 4), and a total of four groups were formed. Results: The mean age of Group 2 was significantly higher than Group 1 (P = 0.049). In addition, the mean age of Group 4 was significantly higher than Group 3 (P = 0.003). Postoperative complications did not differ between Groups 1 and 2 (P > 0.05). While noninvasive mechanincal ventilation (NIMV) requirements did not differ between Groups 3 and 4 (P > 0.05), MV duration and intensive care unit stay were significantly longer in Group 4 (P < 0.05). Conclusion: The AST/ALT ratio, which has been shown to be a predictor of cardiovascular mortality in various studies, was not useful in predicting mortality and morbidity in our study. However, a high FIB?4 index, another hepatic fibrosis index, was found to be associated with increased perioperative bleeding, duration of mechanical ventilation, and cardiac intensive care unit stay, which are important criteria in the prediction of morbidity in cardiovascular surgery.
ABSTRACT
Learning Objective: Hemodynamic monitoring during in?hospital transport of intubated patients is vital; however, no prospective randomized trials have evaluated the hemodynamic consequences of hand versus machine ventilation during transport among pediatric patients� post?cardiac surgery. The authors hypothesized that manual ventilation after pediatric cardiac surgery would alter hemodynamic and arterial blood gas (ABG) parameters during transport compared to mechanical ventilation. Design: A prospective randomized trial. Setting: Tertiary cardiac care hospital. Participants: Pediatric cardiac surgery patients. Materials and Methods: One hundred intubated pediatric patients were randomized to hand or machine ventilation immediately post?cardiac surgery during transport from the operating room to the pediatric post?operative intensive care unit (PICU). Hemodynamic variables, including end?tidal CO2 (ETCO2 ), oxygen saturation, heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), peak airway pressure (Ppeak), and mean airway pressure (Pmean), were measured at origin, during transport, and at the destination. ABG was measured before and upon arrival in the PICU, and adverse events were recorded. The Chi?square test and independent t?test were used for comparison of categorical and continuous parameters, respectively. Results and Discussion: The mean transport time was comparable between hand?ventilated (5.77 � 1.46 min) and machine?ventilated (5.96 � 1.19 min) groups (P = 0.47). ETCO2 consistently dropped during transport and after shifting in the hand?ventilated group, with significantly higher ETCO2 excursion than in machine?ventilated patients (P < 0.05). SBP and DBP significantly decreased during transport (at 5 and 6 min intervals) and after shifting in hand?ventilated patients than in the other group (P < 0.05). Additionally, after shifting, a significant increase in Ppeak (P < 0.001), Pmean (P < 0.001), and pH (P < 0.001), and a decrease in pCO2 (P = 0.0072) was observed in hand?ventilated patients than machine?ventilated patients. No adverse event was noted during either mode of ventilation. Conclusion: Hand ventilation leads to more significant variation in ABG and hemodynamic parameters than machine ventilation in pediatric patients during transport post?cardiac surgery. Therefore, using a mechanical ventilator is the preferred method for transporting post?operative pediatric cardiac patients
