Índice de Angina Renal para el diagnóstico temprano de lesión renal aguda grave en pacientes pediátricos críticamente enfermos

Jennifer Morantes Flórez, Kasey Fuentes, Byron Enrique Piñeres-Olave, Eliana Álvarez et autres

La lesión renal aguda (LRA) afecta hasta al 30% de los niños ingresados en las Unidades de Cuidados Intensivos Pediátricos (UCIP). La creatinina sérica sigue siendo el biomarcador clínico principal para el diagnóstico de LRA; sin embargo, su elevación tardía limita su …

Time Course of Mechanical Ventilation Driving Pressure Levels in Pediatric Acute Respiratory Distress Syndrome: Outcomes in a Prospective, Multicenter Cohort Study From Colombia, 2018–2022

Jaime Fernández‐Sarmiento, Ana María Bejarano-Quintero, Jose Daniel Tibaduiza, Karen Moreno et autres

OBJECTIVES: High driving pressure (DP, ratio of tidal volume (V t ) over respiratory system compliance) is a risk for poor outcomes in patients with pediatric acute respiratory distress syndrome (PARDS). We therefore assessed the time course in level of DP (i.e., …
