extubation failure
Need for reintubation within 48-72 hours of planned extubation, indicating unsuccessful liberation from mechanical ventilation.
Full Definition
Extubation failure is defined as the need for reintubation within 48-72 hours of a planned extubation attempt. It occurs in 10-20% of critically ill patients and is associated with increased morbidity, mortality, and ICU length of stay. Common causes include respiratory muscle weakness, upper airway obstruction, excessive secretions, cardiac dysfunction, and inadequate gas exchange. Risk factors include advanced age, prolonged mechanical ventilation, multiple comorbidities, and failed spontaneous breathing trials. Prevention strategies include careful patient selection, use of noninvasive ventilation, and systematic extubation protocols.
Usage
Usage note: Specify timeframe (usually 48-72 hours) and distinguish from planned reintubation.
