Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aimed to evaluate the influence of different head and neck positions on ventilation with the AuraGain airway.
AuraGain will be placed in all patients, and mechanical ventilation will be performed using a volume-controlled mode with a tidal volume of 10 ml/kg.
The expiratory tidal volume, peak inspiratory pressure, oropharyngeal leak pressure, and ventilation score will be assessed first for the neutral head position and then for the extended, flexed, and rotated head positions in a random order.
Fiberoptic bronchoscopic view will be also assessed for each head and neck positions.
