Abstract: Introduction The laryngeal mask airway (LMA) has emerged as a viable option for managing airways. It is an alternative rescue technique for both anticipated and unanticipated difficult airways in both elective and emergency settings. Methods In our study, 120 patients were divided into two groups: Group S (n=60), standard technique for classic LMA (c-LMA) insertion, and Group R (n=60), reverse technique for classic LMA insertion. The number of insertion attempts was recorded. Insertion was considered easy if there was successful placement on the first attempt with or without maneuvers. We also noted the total time for the successful placement of the airway. Results In Group S, successful LMA placement on the first attempt was done in 93.3% of the patients, compared to 86.7% of the patients in Group R, though it was not statistically significant (p=0.5265). The mean time required to secure the airway in Group S was 16.28±1.93 seconds, whereas in Group R, it was 18.40±2.92 seconds (p<0.0001). The difference in hemodynamic parameters was nonsignificant (p≥0.05). In Group S, incidences of complications were lower compared to Group R, but it was not statistically significant (p>0.05). Irrespective of the technique used, the failure rate was zero. Conclusion Considering the shorter insertion time, along with the lower complication rates, the standard technique may be regarded as the preferred method of LMA insertion over the reverse technique.
