Can diaphragmatic ultrasound be used to predict extubation failure?

摘要

An 8-year-old boy, with a medical history of congenital myotonic dystrophy (CMD) and scoliosis, was admitted to the paediatric intensive care unit (PICU) with a lower respiratory tract infection. He was intubated and received antibiotics. After a prolonged intubation, he tolerated a spontaneous breathing trial (SBT) and received ‘pre-extubation steroids’. He was extubated to non-invasive ventilation (NIV), but quickly was re-intubated. The reason for extubation failure was determined to be secondary to respiratory muscle insufficiency. Would diaphragmatic ultrasound (DU) assessment of function have predicted extubation failure?
