Supraglottic airway (SGA) devices are used to ventilate the patients by delivering gases above the level of vocal cords. Based on their different sealing mechanisms and aspiration protection designs, SGA devices are broadly classified into the first generation devices (inflatable cuff), second generation (preshaped) and third generation devices (self energizing) as per Miller’s new classification.

Ambu aura gain is a second generation SGA made of polyvinyl chloride meant for single use with preformed shape. It is the only anatomically curved SGA device with integrated gastric access and also provides high sealing pressures that reduce the risk of aspiration leading to higher safety level. It has bite block and also a wider airway tube providing as an intubation conduit similar to Ambu aura once and LMA proseal. Baska mask is a novel third generation SGA made of medical grade silicone and available in four sizes of 3, 4, 5 and 6 based on body weight. The characteristic feature of this mask is that the airway pressure is transmitted intermittently to the flexile element of the cuff so that it inflates and deflates with each positive pressure inspiration and expiration respectively thus forming a perfect seal, reducing leaks and making intermittent positive pressure ventilation very efficient.

 Many studies are available comparing the efficiency of 3^rd generation Baska mask with various second generation SGA devices by various authors. Currently, there are no available studies that have compared the efficiency of Ambu aura gain and Baska mask. Hence this prospective randomized comparative study is being undertaken to compare the efficacy and safety between Ambu aura gain and Baska mask as supraglottic airway device in adult patients undergoing elective surgery under general anaesthesia.
