ABSTRACT

Non-invasive respiratory support (NIRS) in adult, pediatric, and neonatal patients with acute respiratory failure (ARF) comprises two treatment modalities, non-invasive mechanical ventilation (NIMV) and high-flow nasal cannula (HFNC) therapy. However, experts from different specialties disagree on the benefit of these techniques in different clinical settings. The objective of this consensus was to develop a series of good clinical practice recommendations for the application of non-invasive support in patients with ARF, endorsed by all scientific societies involved in the management of adult and pediatric/neonatal patients with ARF. To this end, the different societies involved were contacted, and they in turn appointed a group of 26 professionals with sufficient experience in the use of these techniques. Three face-to-face meetings were held to agree on recommendations (up to a total of 71) based on a literature review and the latest evidence associated with 3 categories: indications, monitoring and follow-up of NIRS. Finally, the experts from each scientific society involved voted telematically on each of the recommendations. To classify the degree of agreement, an analog classification system was chosen that was easy and intuitive to use and that clearly stated whether the each NIRS intervention should be applied, could be applied, or should not be applied.

El soporte respiratorio no invasivo (SRNI) comprende 2 modalidades de tratamiento, la ventilación mecánica no invasiva (VMNI) y la terapia de alto flujo con cánulas nasales (TAFCN) que se aplican en pacientes adultos, pediátricos y neonatales con insuficiencia respiratoria aguda (IRA). Sin embargo, el grado de acuerdo entre las distintas especialidades sobre el beneficio de estas técnicas en diferentes escenarios clínicos es controvertido. El objetivo del presente consenso fue elaborar una serie de recomendaciones de buena práctica clínica para la aplicación de soporte no invasivo en pacientes con IRA, avaladas por todas las sociedades científicas involucradas en el manejo del paciente adulto y pediátrico/neonatal con IRA.Para ello se contactó con las diferentes sociedades implicadas, quienes designaron a su vez a un grupo de 26 profesionales con suficiente experiencia en su aplicación. Se realizaron 3 reuniones presenciales para consensuar las recomendaciones (hasta un total de 71) fundamentadas en la revisión de la literatura y en la actualización de la evidencia disponible en relación con 3 categorías: indicaciones, monitorización y seguimiento del SRNI. Finalmente, se procedió a votación telemática de cada una de las recomendaciones, por parte de los expertos de cada sociedad científica implicada. Para la clasificación del grado de acuerdo se optó por un sistema analógico de clasificación fácil e intuitivo de usar, y que expresara con claridad si el procedimiento relacionado con el SRNI debía hacerse, podía hacerse o no debía hacerse.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, that was first recognized in Wuhan, China, in December 2019. Currently, the World Health Organization (WHO) has defined the infection as a global pandemic and there is a health and social emergency for the management of this new infection. While most people with COVID-19 develop only mild or uncomplicated illness, approximately 14% develop severe disease that requires hospitalization and oxygen support, and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by the acute respiratory distress syndrome (ARDS), sepsis and septic shock, and multiorgan failure. This consensus document has been prepared on evidence-informed guidelines developed by a multidisciplinary panel of health care providers from four Spanish scientific societies (Spanish Society of Intensive Care Medicine [SEMICYUC], Spanish Society of Pulmonologists [SEPAR], Spanish Society of Emergency [SEMES], Spanish Society of Anesthesiology, Reanimation, and Pain [SEDAR]) with experience in the clinical management of patients with COVID-19 and other viral infections, including SARS, as well as sepsis and ARDS. The document provides clinical recommendations for the noninvasive respiratory support (noninvasive ventilation, high flow oxygen therapy with nasal cannula) in any patient with suspected or confirmed presentation of COVID-19 with acute respiratory failure. This consensus guidance should serve as a foundation for optimized supportive care to ensure the best possible chance for survival and to allow for reliable comparison of investigational therapeutic interventions as part of randomized controlled trials.

ABSTRACT

La enfermedad por coronavirus 2019 (COVID-19) es una infección del tracto respiratorio causada por un nuevo coronavirus emergente, que se reconoció por primera vez en Wuhan, China, en diciembre de 2019. Actualmente, la Organización Mundial de la Salud (OMS) ha definido la infección como pandemia y existe una situación de emergencia sanitaria y social para el manejo de esta nueva infección. Mientras que la mayoría de las personas con COVID-19 desarrollan solo una enfermedad leve o no complicada, aproximadamente el 14% desarrolla una enfermedad grave que requiere hospitalización y oxígeno, y el 5% puede requerir ingreso en una Unidad de Cuidados Intensivos (1). En casos severos, COVID-19 puede complicarse por el síndrome de dificultad respiratoria aguda (SDRA), sepsis y shock séptico y fracaso multiorgánico. Este documento de consenso se ha preparado sobre directrices basadas en evidencia desarrolladas por un panel multidisciplinario de profesionales médicos de cuatro sociedades científicas españolas (Sociedad Española de Medicina Intensiva y Unidades Coronarias [SEMICYUC], Sociedad Española de Neumología y Cirugía Torácica [SEPAR], Sociedad Española de Urgencias y Emergencias [SEMES], Sociedad Española de Anestesiología, Reanimación y Terapéutica delDolor [SEDAR]) con experiencia en el manejo clínico de pacientes con COVID-19 y otras infecciones virales, incluido el SARS, así como en sepsis y SDRA. El documento proporciona recomendaciones clínicas para el soporte respiratorio no invasivo (ventilación no invasiva, oxigenoterapia de alto flujo con cánula nasal) en cualquier paciente con presentación sospechada o confirmada de COVID-19 con insuficiencia respiratoria aguda. Esta guía de consenso debe servir como base para una atención optimizada y garantizar la mejor posibilidad de supervivencia, así como permitir una comparación fiable de las futuras intervenciones terapéuticas de investigación que formen parte de futuros estudios observacionales o de ensayos clínicos.

ABSTRACT

OBJECTIVE: Overnight polysomnography (PSG) is the gold standard diagnostic tool for sleep apnea-hypopnea syndrome (SAHS) in children. The aim of the present study was to evaluate the usefulness of diagnostic respiratory polygraphy in children with clinically suspected SAHS referred to our sleep-disordered breathing clinic. PATIENTS AND METHODS: We studied 53 children referred with clinical suspicion of SAHS; 29 (54.7%) were boys and the mean (SD) age was 6.4 (2.9) years. After a medical history was taken and a physical examination performed, patients underwent respiratory polygraphy (Edentec) simultaneously with overnight PSG in the sleep laboratory. The 2 diagnostic tools were compared using statistical analysis. RESULTS: SAHS was defined by an obstructive apnea-hypopnea index (OAHI) of 3 or more in overnight PSG and a respiratory disturbance index (RDI) of 3 or more in respiratory polygraphy. The rate of diagnostic agreement was 84.9%. The difference between the mean OAHI and RDI values was not significant (0.7 +/- 5.4; P=.34). The intraclass correlation coefficient between the OAHI and RDI was 89.4 (95% confidence interval, 82.4-93.7; P< .001). When receiver operating characteristic curves were calculated for the OAHI cutoff points used for the diagnosis of SAHS (> or =1, > or =3, and > or =5), the best RDI cutoff for all 3 OAHI values considered was found to be 4.6. When age strata were considered, in children 6 years or older the best RDI cutoff for the 3 OAHI values was 2.1. In children younger than 6 years the best RDI cutoff was 3.35 for OAHI > or =1 and 5.85 for OAHI > or =3 and > or =5. CONCLUSIONS: Respiratory polygraphy in the sleep laboratory is a valid method for the diagnosis of SAHS in children.

ABSTRACT

OBJETIVO: La polisomnografía (PSG) nocturna es la técnica diagnóstica de referencia del síndrome de apneas-hipopneas durante el sueño (SAHS) en niños. El objetivo del estudio ha sido evaluar la utilidad diagnóstica de la poligrafía respiratoria (PR) en niños con sospecha clínica de SAHS remitidos a la Unidad de Trastornos Respiratorios del Sueño. PACIENTES Y MÉTODOS: Se estudió a 53 niños remitidos por sospecha clínica de SAHS (29 varones; 54,7%), con una edad media ± desviación estándar de 6,4 ± 2,9 años. A todos ellos se les realizaron historia clínica, exploración física, PR (Edentec®) y PSG nocturna simultáneamente en el laboratorio de sueño. Se realizó el análisis estadístico para comparar ambas técnicas diagnósticas. RESULTADOS: Definiendo el diagnóstico de SAHS como la presencia de un índice de apneas-hipopneas obstructivas (IAHO) igual o mayor de 3 en la PSG y un índice de eventos respiratorios (IER) de 3 o superior en la PR, la coincidencia diagnóstica fue del 84,9%. La diferencia de medias entre el IAHO y el IER no fue significativa (0,7 ± 5,4; p = 0,34). El coeficiente de correlación intraclase entre el IAHO y el IER fue de de 89,4 (intervalo de confianza del 95%, 82,4-93,7; p < 0,001). Para el diagnóstico de SAHS se consideraron los valores de IAHO iguales o mayores de 1; iguales o mayores de 3, e iguales o mayores de 5. Se calcularon las curvas de eficacia diagnóstica para cada uno de ellos y 4,6 resultó ser el mejor IER para los 3 valores de IAHO considerados. Al analizar por estratos de edad, en niños de 6 años o más el mejor IER obtenido para los 3 valores de IAHO considerados fue 2,1. En niños menores de 6 años se obtuvieron los siguientes valores de IER: 3,35 para IAHO de 1 o superior y 5,85 para IAHO de 3 o mayor y de 5 o superior. CONCLUSIONES: La PR realizada en el laboratorio de sueño es un método válido para el diagnóstico de SAHS en niños

When receiver operating characteristic curves were calculated for the OAHI cutoff points used for the diagnosis of SAHS (³1, ³3, and ³5), the best RDI cutoff for all 3 OAHI values considered was found to be 4.6. When age strata were considered, in children 6 years or older the best RDI cutoff for the 3 OAHI values was 2.1. In children younger than 6 years the best RDI cutoff was 3.35 for OAHI ³1 and 5.85 for OAHI ³3 and ³5. CONCLUSIONS: Respiratory polygraphy in the sleep laboratory is a valid method for the diagnosis of SAHS in children

ABSTRACT

OBJECTIVE: The demand for consultations and diagnostic studies for sleep apnea-hypopnea syndrome (SAHS) has increased, and this has led to considerable delays. We therefore need an updated evaluation of the diagnostic situation to serve as a management tool for specialists and health care administrations responsible for solving the problem. The objective of the present study was to carry out a descriptive analysis of the situation regarding the diagnosis of SAHS in Spanish hospitals. METHODS: We undertook a descriptive cross-sectional observational study. Public and private hospitals listed in the Ministry of Health's 2005 catalog of health care institutions were contacted, and those that routinely evaluate patients for SAHS were included in the study. The person in charge of each hospital filled in a questionnaire concerning the availability of resources and waiting periods for diagnosis. RESULTS: Of the 741 hospitals we contacted, 217 routinely evaluated patients for SAHS. In 88% of these, respiratory polygraphy (RP) (n=168) or polysomnography (PSG) (n=97) was available. The mean waiting period was 61 days for consultation and 224 days for RP. The mean number of RP systems was 0.99 per 100,000 inhabitants, while the recommended number is 3 per 100,000 inhabitants. The mean waiting period for PSG was 166 days. The mean number of PSG beds was 0.49 per 100,000 inhabitants, while the recommended number is 1 per 100,000. CONCLUSIONS: We observed a marked inadequacy of resources that has led to unacceptable waiting periods. While there has been a favorable change in the situation regarding SAHS diagnosis compared to previous studies, there is still room for improvement and it is urgent that healt hcare authorities allocate more resources to this public health problem.

ABSTRACT

Objetivo: La demanda de consultas y estudios diagnósticos del síndrome de apneas-hipopneas durante el sueño (SAHS) se ha incrementado, lo que ha llevado a importantes demoras. Por tanto, es precisa una evaluación actualizada de la situación del diagnóstico que sirva como herramienta de gestión a especialistas y las administraciones sanitarias que tienen la responsabilidad de solventar el problema. El objetivo del presente estudio ha sido realizar un análisis descriptivo de la situación del diagnóstico del SAHS en los hospitales españoles. Métodos: Se ha realizado un estudio descriptivo, observacional y transversal. Se estableció contacto con los centros públicos y privados incluidos en el catálogo de instituciones sanitarias del Ministerio de Sanidad de 2005. Se incluyeron aquellos que evaluaban habitualmente a pacientes con SAHS. El responsable de cada centro rellenó un cuestionario sobre disponibilidad de recursos y demoras para el diagnóstico. Resultados: De los 741 centros con los que se estableció contacto, 217 evaluaban habitualmente a pacientes con SAHS. El 88% disponía de poligrafía respiratoria (PR) (n = 168) o polisomnografía (PSG) (n = 97). La demora media en consulta fue de 61 días, y la demora media para realizar PR, de 224 días. La media de equipos de PR fue de 0,99/100.000 habitantes, cuando lo recomendable es 3/100.000. La demora media para PSG fue de 166 días. La media de camas de PSG fue de 0,49/100.000 habitantes y lo recomendable es 1/100.000. Conclusiones: Se observa una notable deficiencia de recursos que lleva a inaceptables listas de espera. Aunque la situación del diagnóstico de SAHS ha cambiado favorablemente con respecto a estudios previos, sigue siendo mejorable y es imprescindible que las autoridades sanitarias dediquen más recursos a este problema de salud pública
