Failed Intubation
Inability to successfully place an endotracheal tube during general anesthesia induction, creating a potentially life-threatening airway emergency.
Full Definition
Failed intubation in obstetric anesthesia represents one of the most serious airway emergencies, occurring when multiple attempts to place an endotracheal tube are unsuccessful during general anesthesia induction. Pregnant patients are at increased risk due to physiological changes including airway edema, increased oxygen consumption, and rapid desaturation. The incidence is approximately 1 in 300 obstetric general anesthetics, significantly higher than in the general population. Management follows established difficult airway algorithms, prioritizing maternal oxygenation and ventilation while considering whether to proceed with surgery using alternative airway devices, attempt awake fiberoptic intubation, or defer the procedure if not emergent. Documentation must include the number of attempts, equipment used, and final airway management strategy.
Usage
Usage note: Requires detailed documentation of airway management steps and outcomes.
