Infraglottic airway devices and techniques.

description

Airway management involves far more than just proficiency with tracheal intubation techniques. There are several infraglottic techniques available and the method chosen will depend on the accessibility of equipment, the level of training and expertise, and the patient's specific injury or disease. Endotracheal intubation is most commonly performed by direct laryngoscopy. Several modifications of laryngoscope blades and a variety of adjuncts such as bougies may help to accomplish even a difficult airway. Rigid intubation fibrescopes do improve the view of the larynx, especially in patients with difficult anatomy. They also permit tracheal intubation with less head and cervical spine movement than is often generated by direct laryngoscopy. Successful intubation, however, requires considerable experience, as in intubation techniques using flexible fibrescopes. Both the EasyTube and the Combitube serve as an infraglottic or a supraglottic airway. The tip of the EasyTube resembles the one of an endotracheal tube, whereas the Combitube is much more bulky.
