Bronchoscopic Levofloxacin, Gentamicin, or Sham for Acute Exacerbation of Bronchiectasis

Randomized single-center trial evaluating whether bronchoscopic instillation of levofloxacin or gentamicin improves outcomes compared to a sham bronchoscopic procedure in adult ICU patients with non-cystic fibrosis bronchiectasis requiring invasive mechanical ventilation. The primary outcome is a ranked composite of in-hospital mortality and time to ventilator liberation. Safety and procedural adverse events are closely monitored.
