<jats:p>Objetivo: describir las terapias utilizadas en lactantes con bronquiolitis aguda admitidos en 20 Unidades de Cuidados Intensivos (UCI) pediátricos miembros de LARed en 5 países latinoamericanos.Pacientes y Método: Estudio observacional retrospectivo, multicéntrico, de datos del Registro Latinoamericano de Falla Respiratoria Aguda Pediátrica. Se incluyeron niños menores de 2 años ingresados a UCI pediátrica por bronquiolitis aguda comunitaria entre mayo-septiembre 2017. Se recolectaron datos demográficos, clínicos, soporte respiratorio, terapias utilizadas y resultados clínicos. Se realizó análisis de subgrupos según ubicación geográfica, tipo financiación y presencia de academia.Resultados: Ingresaron al registro 1.155 pacientes con falla respiratoria aguda. Seis casos fueron excluidos por no tener formulario completo. De los 1.147 pacientes, 908 eran menores de 2 años. De ellos, 467 tuvieron diagnóstico de bronquiolitis aguda, correspondiendo a la principal causa de ingreso a UCI pediátrica por falla respiratoria aguda (51,4%). Las características demográficas y de gravedad entre los centros fueron similares. El soporte máximo respiratorio más frecuente fue cánula nasal de alto flujo (47%), seguido por ventilación mecánica no invasiva (26%) y ventilación mecánica invasiva (17%), con un coeficiente de variación (CV) amplio entre los centros. Hubo una gran dispersión en uso de terapias, siendo frecuente el uso de broncodilatadores, antibióticos y corticoides, con CV hasta 400%. El análisis de subgrupos mostró diferencias significativas en soporte respiratorio y tratamientos utilizados. Un paciente falleció en esta cohorte.Conclusión: Detectamos gran variabilidad en el soporte respiratorio y tratamientos entre UCI pediátricas latinoamericanas. Esta variabilidad no es explicada por disparidades demográficas ni clínicas. Esta heterogeneidad de tratamientos debería promover iniciativas colaborativas para disminuir la brecha entre la evidencia científica y la práctica asistencial.</jats:p>

<jats:title>Abstract</jats:title><jats:sec> <jats:title>Background</jats:title> <jats:p>Mechanical power is a composite variable for energy transmitted to the respiratory system over time that may better capture risk for ventilator-induced lung injury than individual ventilator management components. We sought to evaluate if mechanical ventilation management with a high mechanical power is associated with fewer ventilator-free days (VFD) in children with pediatric acute respiratory distress syndrome (PARDS).</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>Retrospective analysis of a prospective observational international cohort study.</jats:p> </jats:sec><jats:sec> <jats:title>Results</jats:title> <jats:p>There were 306 children from 55 pediatric intensive care units included. High mechanical power was associated with younger age, higher oxygenation index, a comorbid condition of bronchopulmonary dysplasia, higher tidal volume, higher delta pressure (peak inspiratory pressure—positive end-expiratory pressure), and higher respiratory rate. Higher mechanical power was associated with fewer 28-day VFD after controlling for confounding variables (per 0.1 J·min<jats:sup>−1</jats:sup>·Kg<jats:sup>−1</jats:sup> Subdistribution Hazard Ratio (SHR) 0.93 (0.87, 0.98), <jats:italic>p</jats:italic> = 0.013). Higher mechanical power was not associated with higher intensive care unit mortality in multivariable analysis in the entire cohort (per 0.1 J·min<jats:sup>−1</jats:sup>·Kg<jats:sup>−1</jats:sup> OR 1.12 [0.94, 1.32], <jats:italic>p</jats:italic> = 0.20).

In subgroup analyses by age, the association between higher mechanical power and fewer 28-day VFD remained only in children < 2-years-old (per 0.1 J·min<jats:sup>−1</jats:sup>·Kg<jats:sup>−1</jats:sup> SHR 0.89 (0.82, 0.96), <jats:italic>p</jats:italic> = 0.005). Younger children were managed with lower tidal volume, higher delta pressure, higher respiratory rate, lower positive end-expiratory pressure, and higher PCO<jats:sub>2</jats:sub> than older children. No individual ventilator management component mediated the effect of mechanical power on 28-day VFD.</jats:p> </jats:sec><jats:sec> <jats:title>Conclusions</jats:title> <jats:p>Higher mechanical power is associated with fewer 28-day VFDs in children with PARDS. This association is strongest in children < 2-years-old in whom there are notable differences in mechanical ventilation management. While further validation is needed, these data highlight that ventilator management is associated with outcome in children with PARDS, and there may be subgroups of children with higher potential benefit from strategies to improve lung-protective ventilation.</jats:p> <jats:p><jats:bold>Take Home Message</jats:bold>: Higher mechanical power is associated with fewer 28-day ventilator-free days in children with pediatric acute respiratory distress syndrome.
