Study Design— this was a Hospital based, randomized, single blind Interventional study conducted in the department of Anaesthesiology, SMS

Medical college & attached group of hospitals, Jaipur,.Sample size was calculated to be 45 in each group(Laryngeal mask airway supremetm S

group and I–Geltm I group) at alpha error 0.05 & power 80% to verify the expected difference of 1.5(±2.5)sec. (as per seed article) in mean insertion

time among I GELTM group and LMA SupremeTM group.

Result and discussion: In our study we found that Airway trauma was observed only in one patient in group I and in two patients in group S. The

difference was statistically not significant (p=1.000). The perioperative complication which included Coughing, broncho & laryngospasm,

hypoxia, regurgitation/aspiration were noted. Coughing & bronchospasm was noted in one patient in group S. The difference was statistically not

significant (p=1.000). The post–operative complication (24 hr post surgery) which included blood staining/hoarseness of voice/sore

throat/difficulty in swallowing/vomiting were noted. Sore throat was noted in one patient in the group I & 3 in group S. Blood staining of the device

in one patient in the group I & 2 in group S. The difference was statistically not significant (p=1.000).

Conclusion: This study demonstrates that new Supraglottic airway devices I–GelTM and LMA SupremeTM were better alternative to

endotracheal tube in patients undergoing elective surgeries under general anesthesia. But peri and post operative complications were more in

Laryngeal mask airway supremetm group than I–Geltm group .Further multicentre mega trials were indicated to assess safety and performance

compared to other supraglottic airway devices.
