Background and Aims: Baska mask is a newly introduced membranous cuffed supraglottic device whereas I-gel is made up of thermoplastic elastomer, both suitably designed from the anatomical perspective of the airway. Settings and Design: We conducted randomized controlled comparative trial of the Baska mask versus I-gel in a patient undergoing laparoscopic cholecystectomy. Subjects and Methods: A total of 100 adult patients in the age group of 20-70 years undergoing elective laparoscopic cholecystectomy were randomly divided into two groups as follows: (1) Baska mask group and (2) I-gel group. The primary outcome was to compare oropharyngeal leak pressure (OLP) of Baska mask and I-gel groups. The secondary outcome was the ease of insertion and removal, number of attempts, insertion time, leak fraction, and laryngopharyngeal morbidity. Statistical Analysis Used: Demographic details were compared using the Chi-square and t-tests. Student's t-test for independent variables was used to compare means of data obtained. Results: Mean OLP was significantly higher in Baska mask group than I-gel group at insertion (29.54 ± 1.41 cm H2O vs. 23.16 ± 3.07 cm H2O, P = 0.02) and 30 min after insertion (33.54 ± 1.16 cm H2O vs. 25.97 ± 2.25 cm H2O, P = 0.001). Insertion time was 12.33 ± 2.61 s with Baska mask and 11.31 ± 1.84 s with I-gel (P = 0.02). Insertion was very easy in 58% of patients in Baska mask and 76% of patients in I-gel (P = 0.03). The leak fraction of Baska mask was significantly less than I-gel (3.56 ± 3.6 vs. 7.16 ± 2.45, P = 0.01). Laryngopharyngeal morbidity was comparable in the two groups. Conclusion: Baska mask is more effective in providing greater OLP compared to I-gel without any increase in laryngopharyngeal morbidity.
