High-Flow Nasal Cannula After Extubation in Acute Brain Injury

Sponsor: Bach Mai Hospital

Summary

Patients with acute brain injury after neurosurgery are at increased risk of extubation failure after removal of the endotracheal tube. High-flow nasal cannula (HFNC) may provide better post-extubation respiratory support than conventional oxygen therapy (COT), but evidence in post-neurosurgical patients remains limited. This prospective observational study evaluated adult post-neurosurgical patients with acute brain injury who underwent planned extubation in the Surgical Intensive Care Unit of Bach Mai Hospital, Vietnam. Patients received either HFNC or COT after extubation according to routine clinical practice and the decision of the attending ICU physicians. The primary outcome was treatment failure, defined as reintubation or escalation of respiratory support within 5 days after extubation. Secondary outcomes included tracheostomy, ventilator-associated pneumonia, ICU length of stay, total duration of mechanical ventilation, and time from extubation to reintubation. Propensity score matching was used to reduce baseline imbalance between groups.
