Summary
Apneic oxygenation via high-flow nasal cannula offers a safe airway management alternative for laryngotracheal procedures. This method allows extended operating times without intubation, improving visualization and avoiding complications.
Area of Science:
- Anesthesiology
- Respiratory Medicine
- Surgical Airway Management
Background:
- Apneic oxygenation can enhance visualization and reduce complications in laryngotracheal procedures.
- It serves as an alternative to intubation and jet ventilation.
Purpose of the Study:
- To evaluate the safety and efficacy of apneic oxygenation using a high-flow nasal cannula.
- To determine its suitability as an airway management strategy for select laryngotracheal procedures.
Main Methods:
- Retrospective review of 38 adult patients undergoing laryngotracheal procedures with apneic oxygenation.
- Humidified oxygen delivered via high-flow nasal cannula.
- Data analyzed using SAS version 9.4.
Main Results:
- Mean apneic time was 23.9 minutes.
- A significant correlation was found between apneic time and minimum oxygen saturation (r=0.38, p=0.018).
- 21 patients (55%) resumed spontaneous ventilation without needing further airway intervention.
Conclusions:
- Apneic oxygenation is a viable alternative airway strategy for select laryngotracheal procedures.
- It enables prolonged surgical access without endotracheal intubation under general anesthesia.

128
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

01:21Tracheostomy Decannulation
453
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
