extubation
Pronunciation: ek-stoo-BAY-shun
Planned removal of an endotracheal tube when mechanical ventilation is no longer required or transitioning to non-invasive support.
Full Definition
Extubation is the planned removal of an endotracheal tube from a patient who has been mechanically ventilated, typically when respiratory function has improved sufficiently to maintain adequate gas exchange independently or with less invasive support. In pediatric patients, the decision to extubate requires careful assessment of respiratory drive, airway reflexes, ability to handle secretions, and underlying lung function. Pre-extubation criteria often include stable vital signs, adequate gas exchange on minimal ventilator settings, and successful spontaneous breathing trials. Post-extubation monitoring is critical as children have smaller airways and may be at higher risk for extubation failure, potentially requiring reintubation. The procedure should be performed in a controlled environment with appropriate personnel and emergency equipment readily available.
