Utilidad de la ecografía diafragmática en una paciente con síndrome de Guillain Barré: Reporte de caso

Guillain-Barré Syndrome (GBS) is an acute inflammatory neuropathy that can cause respiratory paralysis and require mechanical ventilation. Diaphragmatic ultrasound is useful for assessing respiratory function in these patients and guiding ventilator weaning. We present the case of a 16-year-old adolescent with Guillain-Barré Syndrome and progressive respiratory failure who was admitted to the intensive care unit under mechanical ventilation and vasoactive support, where a chest CT revealed left-sided atelectasis later confirmed by fiberoptic bronchoscopy, and subsequent diaphragmatic ultrasound showed an excursion of less than 10 mm, indicating diaphragmatic dysfunction, leading to the initiation of tracheostomy and respiratory rehabilitation with progressive clinical and functional improvement, as the use of diaphragmatic ultrasound enabled early identification of diaphragmatic dysfunction and guided critical therapeutic decisions such as tracheostomy. Its use in critically ill patients with Guillain-Barré syndrome represents a valuable, noninvasive, and safe tool for optimizing ventilatory management and improving clinical outcomes.
