To evaluate a novel airway device, Gnana Laryngeal Airway in clinical practice: A pilot study.

Laryngeal mask airway (LMA) devices are presently use worldwide by anaesthesiologist for airway management in adults and children’s and is considered a novel route to provide general anaesthesia. There are currently seven versions of the LMA’s available, which are LMA-Classic, LMA-Unique, LMA-Fastrach, LMA-ProSeal, LMA-Supreme, LMA-Ambu and LMA-Soft Seal. Recently, a laryngeal airway device was designed as a latest version of LMA called Gnana laryngeal airway. It consists of an elliptical cuffed mask and an airway tube. The concave portion of the mask when inflated faces the vocal cords. With the aim of keeping the area around the laryngeal mask clean of secretions, an inbuilt small suction port has been added into convex part of the laryngeal mask airway. there are numerous clinical studies involving the use of various version of LMAs, attesting to their safety and performance in various clinical situations. It is hypothesised that the Gnana laryngeal airway might reduce the possible airway complication by incorporation of suction port on its convex surface. At present there are limited trials done on the Gnana laryngeal airway. The purpose of this study is to evaluate Gnana laryngeal airway in terms of success rate, ease and speed of insertion, performance during general anaesthesia (oropharyngeal leak pressure (OLP) measurement after insertion of device by documented method and exact placement of device seen by flexible fiberoptic view of larynx) and rate of complications in patients requiring anaesthesia for various surgical procedures.
