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

ABSTRACT

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.
