Endotracheal Intubation Indications

Endotracheal intubation is the gold standard for definitive airway management. Indications are categorized by the necessity to protect, maintain, or ventilate the airway.


Category Clinical Scenarios
Airway Protection Loss of protective airway reflexes (e.g., GCS < 8), coma, massive hematemesis/hemoptysis, airway burns/edema.
Oxygenation/Ventilation Refractory hypoxemia, hypercapnic respiratory failure, and impending respiratory fatigue.
Surgery/Procedure General anaesthesia, procedures requiring neuromuscular blockade, or prone/lateral positioning.


High-Yield Clinical Notes:

  • The “Airway Assessment”: Always perform a rapid assessment (e.g., LEMON criteria) before attempting intubation.
  • GCS < 8: A classic, though not absolute, teaching trigger for securing the airway to prevent aspiration and ensure adequate ventilation.
  • Rapid Sequence Induction (RSI): Standard approach for intubating patients with a “full stomach” to prevent aspiration, utilizing rapid-onset induction agents and muscle relaxants.
