A Comparative Study Between Laryseal Pro Supra Glottic Device (SGD) With Proseal Laryngeal Mask Airway

The laryseal pro SP will be advanced at a forward angle aiming for the back of the tongue and soft palate. Then the colored connector will be pushed by index finger till feeling resistance . Device insertion will be considered successful by observing bilateral chest wall movement as well as a stable square-wave capnogram trace

The cuff will be inflated with air and the cuff's pressure will be adjusted to 70 mmHg using a cuff pressure manometer. the device will be lubricated well on both sides, head and neck were placed in neutral position, the proximal firmer part of the device will be compressed between the thumb and two fingers and advanced toward hard and soft palate, the tab will be pulled slightly if needed to increase curvature of the device for better fitting, the device will be advanced till resistance felt.
