 Background: New supraglottic devices are being introduced into the market with various claims regarding their safety and efficacy.  Objectives: To compare number of attempts at insertion, oropharyngeal leak pressure, associated trauma, fiberoptic assessment of proper placement and the hemodynamic changes with use of Baska mask and I Gel.  Material and methods: The present study was a prospective, randomized, study. Sixty patients undergoing surgeries under general anesthesia were included. Patients were divided into two equal groups and received anesthesia following a standardized protocol. In Group B patients Baska mask was used whereas I-Gel was used in Group I to provide anesthesia. Statistical analysis was done using Chi-square test and Independent sample t-test as applicable.  Results: Time taken for securing airway and number of attempts taken were significantly higher in Group B. Incidence of trauma was comparable. Oropharyngeal leak pressure (OLP) was significantly higher in Group B (36.33±5.68 vs 25±5.79), percentage of patients with Grade I-III score on fiberoptic assessment was also significantly higher in Group B. Both groups had comparable heart rate (HR) and mean arterial pressure (MAP) before induction, after induction and at 10 min after securing airway. At 1, 3 and 5 minutes after securing airway Group B had significantly higher HR and MAP.  Conclusion: I Gel insertion was quicker, less traumatic, required fewer attempts and was associated with blunted hemodynamic responses. But OLP was significantly higher with better fiberoptic assessment score of proper placement with use of Baska mask.
