Tulip Airway in Difficult Mask Ventilation (TADMV)

During surgery, right after anesthesia is given, the first step to help the patient breathe is to provide breathing support with a mask. This step is very important because if there is a problem with mask ventilation, the anesthesia team must quickly use other methods to help the patient breathe. For some people, mask ventilation can be more difficult. Factors such as older age, having a beard, missing teeth, being overweight, sleep apnea, or certain facial shapes can make this process harder. To make mask ventilation easier, special devices placed in the mouth are used. The most common one is called the Guedel airway. In recent years, a new device called the Tulip airway has also been introduced. The shape and features of the Tulip airway are designed to make breathing support easier. In this study, we will compare the Tulip airway and the Guedel airway in patients who are expected to have more difficult mask ventilation. Our goal is to find out which device makes it easier and safer to help patients breathe.
