Comparison of success rate of blind tracheal intubation on using LMA Fastrach and AMBU Auragain as an intubating device for general anaesthesia in adult patients.

Abstract

INTRODUCTION
LMA Fastrach (Intubating LMA) was designed by Dr Archie Bran. ILMA is designed to provide a dedicated airway and allow placement of moderate size tracheal tubes in both easy and difficult airways. The short rigid anatomically curved stem of ILMA leads to easy insertion even by novices but its potential to cause mucosal damage limits its use. It has a soft inflatable laryngeal mask and a rigid anatomically curved airway tube terminating in standard 15mm connector and is wide enough to accept a cuffed 8mm tracheal tube. Device measures 20mm in transverse diameter at its widest point. An epiglottic elevator bar in mask aperture elevates epiglottis when endotracheal tube is passed through the aperture. The ILMA permits single handed insertion from any operator position, without moving the head or neck from neutral position and without placing fingers in pt mouth. It can be used as an airway device in its own right, permitting ventilator support and oxygenation between intubation attempts.
