Abstract
The laryngeal mask airway (LMA) is a new airway management device andhas become increasingly popular in anaesthesia to maintain airway patency during spontaneous and controlled ventilation.the standard LMA is not an ideal intubation aid as the airway tube is too narrow to accommodate an adult diameter tracheal tube, too long to ensure a normal length tracheal tube will reach the trachea and not sufficiently rigid to function as a guide to exact alignment of the mask with glottis. In addition, the mask aperture base may obstruct passage of the tracheal tube. In an attempt to overcome these limitations, a prototype intubating laryngeal mask airway (ILMA) has been developed.Presently there are contradictory reports regarding haemodynamic changes during laryngoscopy, intubation and extubation with or without ILMA. Hence this study was planned to evaluate the haemodynamic changes to insertion and removal of LMA in comparison with ILMA in healthy patients as reduced haemodynamic response may be beneficial to the patients with especially with cardiovascular and cerebral diseases.
