Background: This study was conducted to compare the success rates of three different techniques of i-gel insertion standard, rotational, and triple airway maneuver in anaesthetized, paralyzed adult patients. Materials and Methods: This prospective randomized trial included 150 patients and was conducted in the Department of Anaesthesia, Dr. R.P.G.M.C., Kangra at Tanda during the study period. Patients were randomly allocated into three groups (n = 50 each): Group A (standard technique), Group B (rotational technique), and Group C (triple airway maneuver). The primary outcome measure was the first-attempt success rate of i-gel insertion. Secondary outcomes included insertion time and the number of insertion attempts. Results: In Group A, the first-attempt success rate was 86%, with 14% of patients requiring a second attempt. In Group B, the first-attempt success rate was 96%, while 4% required a second attempt. In Group C, the first-attempt success rate was 94%, with 6% requiring a second attempt. Although the success rate was higher in the rotational and triple airway maneuver groups compared to the standard group, the difference was not statistically significant (p = 0.149), indicating that all three techniques were comparable in terms of first-attempt success. The mean number of insertion attempts was significantly higher in the standard group compared to the rotational group (1.30±0.46 vs. 1.04±0.19; p<0.0001) and the triple airway maneuver group (1.30±0.46 vs. 1.06±0.24; p = 0.001). The mean insertion time was 11.76±4.92 seconds in the standard group, 10.42±2.89 seconds in the rotational group, and 8.50±2.44 seconds in the triple airway maneuver group. Insertion time was significantly shorter in the triple airway maneuver group compared to the standard group (p<0.0001) and the rotational group (p = 0.027). Conclusion: The triple airway maneuver technique showed a higher first-attempt success rate, shorter insertion time, and fewer insertion attempts compared to the standard and rotational techniques for i-gel insertion in anaesthetized, paralyzed adult patients.
