Multiprofessional Critical Care Review: Pediatric (2023)-Acute Lung Injury

Video Transcription

Video Summary

The video is a presentation on pediatric acute lung injury and acute respiratory distress syndrome (ARDS). The presentation covers several key topics including the epidemiology and risk factors of ARDS, the pathogenesis of lung dysfunction, diagnosis, pathophysiology, medical management principles, open lung strategy, ventilator management, and implications of fluid management. <br /><br />ARDS is a clinical syndrome characterized by diffuse inflammation in the lungs, resulting in hypoxemia. There is no definitive diagnostic test for ARDS, so definitions have historically been clinical. The current definitions include acute onset of disease with low oxygen levels (PF ratio less than 300 for ALI, less than 200 for ARDS), bilateral lung infiltrates, and exclusion of other causes. In pediatric ARDS, age-specific definitions and criteria have been developed. <br /><br />Ventilator management is a key aspect of ARDS treatment, with a focus on lung protection. Lung protective ventilation includes using low tidal volumes based on functional residual capacity and ventilation at appropriate pressures to reduce the risk of barotrauma and volutrauma. Prone positioning has been shown to improve oxygenation in adults with ARDS, but there is limited evidence for its use in pediatrics. Fluid management strategies, aiming to maintain adequate intravascular volume while preventing positive fluid balance, may also improve outcomes in pediatric ARDS. Overall, there is a need for more research and randomized controlled trials to further optimize management strategies for pediatric ARDS.
