The Influence of Head and Neck Position on Performance of Ambu AuraGainTM in Children

The Influence of Head and Neck Position on Performance of Ambu AuraGainTM in Children

The influence of different head and neck positions on the effectiveness of ventilation with the Ambu AuraGain airway remains unevaluated.

This study aimed to evaluate the influence of different head and neck positions on ventilation with the AuraGain airway.

An 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.

Inclusion Criteria:

• Children < 7 years old who scheduled for general anesthesia using supraglottic airway

Exclusion Criteria:

• Children who require tracheal intubation
• Emergency operation without NPO
• History of C-spine surgery or disease
• History of Esophageal disease or surgery
