Abstract
Unlike the endotracheal tube, the quality of ventilation through SADs can be influenced by the head and neck position because the pressure applied to the SAD cuff can be changed according to the changes in the oropharyngeal structure. The seal between the SAD and oropharynx can be assessed by the oropharyngeal leak pressure (OLP).
The changes in OLP and ventilation quality according to head and neck position are directly related to the anterolateral diameter of the pharyngeal space and the relative cuff sizes of SADs. Relative position of the opening of the SAD to the vocal cord inlet is important for effective ventilation; a predictor that may not appropriately be represented by the OLP.
Due to its anatomical and structural characteristics, we hypothesized that the effect of head and neck positioning on the OLP and ventilation quality of the AuraGain may be different compared to previous SADs. Furthermore, the effects of head-neck position changes on the functioning of AuraGain in the paediatric population have not yet been evaluated
Therefore, the primary aim of this study was to investigate the influence of lateral head and neck rotation on the OLP of AuraGain in children. The secondary aims of this study were to evaluate the changes in the peak inspiratory pressure, expiratory tidal volume, fibreoptic bronchoscopic view and ventilation score according upon lateral head and neck rotation in the same population.
