A Randomized Comparison of Patient’s Ventilation at Induction of Anaesthesia Between Tulip GT® Airway and Guedel Airway-Face Mask by Anaesthesia Residents

The Tulip® airway is a recently introduced single sized ventilating oropharyngeal airway. Methods: We performed a randomized, controlled study of lung ventilation by anaesthesia residents using either Tulip GT® airway or face mask with Guedel airway in 100 anaesthetised patients, where the ease of insertion, intracuff pressure and volume were measured, as were the end-tidal carbon dioxide levels, airway pressures and tidal volumes over first three breaths. Results: Successful ventilation was observed with Tulip airway which provided a patent airway in comparison to facemask with a Guedel airway but 15 patients required additional cuff volume in Tulip airway. Conclusion: We conclude Tulip® airway can be used as an adjunct for airway management even by inexperienced users.

Awake fiberoptic orotracheal intubation using a modified Guedel airway in a patient with craniocervical instability and an anticipated difficult airway: A case report

In patients with upper cervical instability, airway management may provoke subluxation of the craniocervical region and neurologic injury, and can be challenging for the anesthesiologist. Endotracheal intubation using a fiberoptic bronchoscope is frequently used in these patients to minimize spine motion, but this procedure may fail in patients with altered airway anatomy. When fiberoptic endotracheal intubation fails in these patients, optional intubation methods are limited. We describe successful awake fiberoptic orotracheal intubation using a modified Guedel airway divided in the midline for a 59-year-old man with an anticipated difficult airway, due to limited mouth opening, a nasopharyngeal tumor, and craniocervical spine instability after failure of conventional fiberoptic orotracheal intubation.
