Haemodynamic response to laryngeal mask airway versus endotracheal tube, a clinical comparative study
Author(s): Abhijit Tarat, Arnav Das, Ramesh Kumar
Abstract: Background: Laryngeal mask airway is becoming increasingly popular in anaesthetic practice. It has the advantage of maintaining airway both for spontaneous and controlled ventilation without requiring laryngoscopy and tracheal intubation. Aims: The aim of this study was to measure the haemodynamic response to the insertion of the LMA in normotensive patients and compare it with endotracheal intubation and also chances of regurgitation and aspiration associated with the use of it. Methods: The study comprised of 100 cases undergoing elective surgery of 45 minutes to 1 hour duration divided into 2 groups of 50 each. In Group 1, endotracheal tube was placed whereas in group 2 LMA was inserted. Pulse, blood pressure and ECG observed after one minute, three minute and five minutes. Conclusion: The effect of haemodynamic response using two different techniques (ETT and LMA) was similar but the magnitude of response was less with LMA and also the risk of regurgitation with it not greater than ETT at least in short duration elective surgery.
