Background: The adoption of supraglottic airways has been growing rapidly and especially popular for airway management in ambulatory surgical procedures. Baska® mask is a new entrant in supraglottic airway devices. Aims and Objective: The purpose of this study was to compare the efficacy and utility of thethe Baska®mask andProsealTM laryngeal mask airway during ambulatory procedures performed under general anesthesia without the use of a muscle relaxant. Materials and Methods:Eighty American Society of Anesthesiologists grade I–II patients, aged 21–55 years, scheduled for elective ambulatory procedures under general anesthesia were randomly assigned to Group B or Group P in this randomized prospective trial using Baska® mask and ProsealTM LMA, respectively.The effective airway time was the most significant finding. Secondary outcomes included insertion ease, number of tries, oropharyngeal leak pressure, hemodynamic parameters, and pharyngolaryngeal adverse events. Statistical analysis: All statistical computations were performed using SPSS (Statistical Package for the Social Science). Fisher's test and Chi-square test were used for categorical variables. The study groups' continuous variables were compared using the unpaired t-test. Results: Group B had a statistically significant shorter effective airway time in comparison to group P, (14.50 1.66 vs. 17.95 1.81 s, respectively) (P= 0.000). The oropharyngeal leak pressure in group B was significantly higher than that in group P (30.10 2.90 vs. 26.552.06 cm H2O, respectively) (P= 0.000). Conclusion:The Baska® mask requires less time to insert and has a higher oropharyngeal leak pressure as compared to ProsealTM LMA. It has better suitability for both controlled and spontaneous ventilation in ambulatory surgery.
