Abstract :

BACKGROUND: The laryngeal mask airway has revolutionized the management of patients who would previously have received anesthesia by facemask enabling the anesthetist to both hands free. The increasing emphasis on “day care anesthesia” has led to greater use of laryngeal mask airway, I–gel as an alternative to face mask and in some cases for conventional tracheal intubation AIM The aim of my study is to compare the airway seal pressure of Classical LMA, proseal LMA and I–gel in patients undergoing minor surgical procedures under total intravenous anesthesia METHODS. Group A – Patients in whom classical LMA was used Group B Proseal LMAand group c I gel was used. Oropharyngeal seal pressure was noted by closing the expiratory valve at a fixed gas flow of 5L per minute and recording the airway pressure at which the gas leaked into the mouth Manometric stability test is one of the most reliable test RESULTS. In the proseal group the airway seal pressure achieved was superior when compared to C LMA and IGEL These results were found to be statistically significant CONCLUSION The oropharyngeal seal pressure was higher in Proseal LMA than other two group
