Abstract: ProSeal Laryngeal mask airway is increasingly being used as an airway device for laparoscopic surgery. Nitrous oxide can diffuse into the cuff of airway devices and may further increase the intracuff pressure. The present study was designed to investigate the intracufff pressure changes during anesthesia with and without use of nitrous oxide in patients undergoing laparoscopic surgery and also note post-operative complications like sore throat, dysphagia and dyshphon.33 patients of ASA Grade 1 and 2 were randomized and allocated to group A (receiving mixture of nitrous oxide and oxygen) and Group B (receiving oxygen). Following insertion of Proseal LMA, the cuff was inflated to an intracuff pressure of 45 mm Hg. The cuff pressure measured every 5 mins and also assessment of post-operative complications. The maximum intracuff pressure recorded in group A was 113 cm of H20, which was 87 % higher than the baseline and in group B was 71.4 cm H20, which was 19 % percent higher than the baseline. The percentage rise in cuff pressure every 5 mins was also significant in Group A, being maximum at 20 mins. The incidence of complications in both the groups was statistically insignificant.
