Study Notes
Airway Management
- Effective airway management involves addressing challenges and potential complications, such as aspiration, esophageal intubation, dental injury, hypoxic brain injury, and even death.
Incidence of Difficult Airway
- The incidence rates of difficult and impossible face mask ventilation are 1.4-5.0% and 0.07-0.16%, respectively.
- Factors contributing to difficult airway management include age > 55 years, no teeth, preoxygenation, restricted mouth opening, stiff lungs or C-spine, obesity, radiation, and tumor.
Preoxygenation
- Adequate preoxygenation is crucial before initiating airway management.
- It takes approximately 9 minutes for oxygen saturation to decrease to 80% when sufficient preoxygenation is performed.
- Methods for preoxygenation include providing oxygen for 3 minutes through normal breathing or supplying oxygen for 1 minute through vital capacity breathing.
Awake Tracheal Intubation
- Awake tracheal intubation should be considered in the presence of predictors of difficult airway management.
- A cognitive aid such as a checklist is recommended before and during awake tracheal intubation.
- Supplemental oxygen should always be administered during awake tracheal intubation.
- Effective topicalization must be established and tested, with a maximum dose of lidocaine not exceeding 9 mg/kg of lean body weight.
Management of Unanticipated Difficult Airway
- When encountering an unanticipated difficult airway, it is crucial to call for assistance and optimize oxygenation.
- Up to three intubation attempts are allowed; additional attempts may be made if a more experienced healthcare provider is available.
Anesthesia and Intubation
- Intubation after induction of general anesthesia involves performing sufficient preoxygenation and maintaining oxygen supply throughout airway management.
- The essential factors in awake tracheal intubation are conveniently described using the acronym "sTOP" (sedation, topicalization, oxygenation, and performance).
Equipment for Emergency Invasive Airway Management
- Essential equipment includes tracheal tube introducer (bougie), stylets, equipment for emergency invasive airway management (e.g., cricothyroidotomy), supraglottic airway, nasal cannula, and oxygen face mask.
