Background:

Airway management extends beyond basic tracheal intubation.
Multiple infraglottic techniques exist, chosen based on resources, skill, and patient factors.
Direct laryngoscopy is the standard for endotracheal intubation.

Purpose of the Study:

To review various airway management techniques.
To discuss adjuncts and alternative devices for difficult airways.
To compare different intubation methods and devices.

Main Methods:

Review of direct laryngoscopy modifications and adjuncts (e.g., bougies).
Evaluation of rigid and flexible intubation fiberscopes for laryngeal visualization and intubation.
Discussion of infraglottic/supraglottic devices like EasyTube and Combitube.

Main Results:

Laryngoscope modifications and adjuncts can aid difficult airways.
Rigid fiberscopes offer improved laryngeal view with less cervical spine movement.
Flexible fiberscope intubation demands significant experience; EasyTube and Combitube offer alternative airway access.

Conclusions:

Successful airway management relies on selecting appropriate techniques and devices.
Advanced tools like fiberscopes and devices like EasyTube/Combitube provide options for challenging intubations.
Expertise is crucial for advanced airway management techniques.
