Comparison of laryngeal mask airway protector and intubating laryngeal mask airway for ease of fiberoptic guided tracheal intubation in adult patients- a one year hospital based randomised controlled trial

Abstract

Background: Anesthesiologists play a critical role in ensuring optimal gas exchange. While advancements like video laryngoscopy and supraglottic airway devices (SADs) have improved airway management, challenges persist, particularly during emergence. The laryngeal mask airway (LMA), introduced by Archie Brain in 1988, revolutionized airway management, offering a less invasive alternative to endotracheal intubation. The intubating LMA (ILMA), designed for fiberoptic-guided tracheal intubation, enhances success in difficult airway scenarios. The LMA Protector™, a second-generation SAD, improves upon traditional designs by incorporating gastric drainage channels and facilitating fiberoptic intubation. This study compares the ILMA and LMA Protector in terms of insertion ease and efficacy as conduits for fiberoptic-guided intubation in adults undergoing general anesthesia. Aims and Objectives: The objectives of the study is to compare the ease of fiberoptic guided tracheal intubation through the LMA Protector and Intubating LMA and the grade of view of glottic aperture through LMA Protector and Intubating LMA with a flexible fibrescope
