- Brief Summary
The laryngeal mask airway is one of the airway devices that has gained popularity during the past decade.LMA cuff inflation with the normal recommended injection volume results in the residual volume of the cuff being exceeded during anaesthesia resulting in severe and even fatal injury including tracheal pain or stridor. A variety of media are used for cuff inflation which varies with their efficacy to maintain a stabilised cuff pressure and to prevent post intubation-related emergence phenomenon. This will be a prospective randomized double blind study which will be done to compare the effects of laryngeal mask airway (LMA) supreme cuff inflation with air, air: oxygen mixture and oxygen: nitrous oxide mixture in adults. The study will be carried out on 120 adults of ASA grade I and II who will be divided into three groups of 40 each. Supreme LMA cuff inflation will use Air only in group A, Oxygen: Air mixture in Group OA andOxygen: Nitrous oxide mixture in Group ON. All the groups will be compared with respect to changes in cuff pressure intraoperatively with different gas composition used to inflate the LMA Supreme with a manometer and
post-operative pharyngolaryngeal morbidity. The observations will be recorded on the proforma and the results will be statistically analysed in the three groups.
