Blockbuster LMA versus Baska Mask in pa-tients undergoing laparoscopic cholecystec-tomy: a randomized clinical trial

Objectives: This study compared the performance and safety of the Blockbuster Laryngeal Mask Airway (LMA) and the Baska Mask (BM) in patients undergoing laparoscopic cholecystectomy (LC). Methodology: In this randomized open-label trial, 140 individuals between the ages of 18 and 60 years, underwent elcetive LC. Patients were chosen at random to receive either the Blockbuster LMA (Group L) or the Baska Mask (Group B). Results: The groups exhibited comparability in terms of insertion time, number of attempts, and success rate. Group B had a statistically significant reduction in gastric tube insertion time (P = 0.005). Oropharyngeal leak pressure (OLP) was significantly higher in Group B, both just after insertion (P < 0.001) and at 30 min (P = 0.002). Hemodynamic parameters and peak airway pressure (PAP) were insignificantly different between the groups. Postoperative complications (pain, difficulty swallowing, cough, and blood on the device) were insignificantly different between the groups. Conclusions: The BM exhibited a more effective oropharyngeal seal and facilitated the insertion of the stomach tube in comparison to the Blockbuster LMA, while both devices exhibited comparable insertion characteristics, hemodynamic profiles, and postoperative complications in patients undergoing LC.
