Objectives: The study was designed to compare the respiratory mechanics of the patients with either I-Gel or ProSeal LMA as airway device during positive pressure ventilation while undergoing laparoscopic hernia repair surgeries. The other parameters compared are ease of insertion and airway trauma. Methodology: This randomized control study was conducted in our tertiary care hospital. 110 patients of ASA PS class 1-2 were randomly divided into 2 groups of 55 each. Premedication and anesthesia technique were standardized in both the groups. One group had PLMA as their airway device and the other group had I-gel as their airway device. We compared the respiratory mechanics (dynamic compliance, airway resistance and peak airway pressure) of these patients during positive pressure ventilation. The other parameters compared were ease of insertion and airway trauma. Results: I-Gel is a better device compared to PLMA in terms of dynamic compliance, peak airway pressure, airway resistance and ease of insertion was higher with PLMA. There was no significant difference in blood staining after removal of the device or trauma to lips, tongue and teeth between two groups. Conclusion: From our study, we concluded that I-Gel is a better device compared to PLMA in terms of dynamic compliance, peak airway pressure, airway resistance and ease of insertion. There was no significant difference in blood staining after removal of the device or trauma to lips, tongue and teeth between two groups.
