Comparison of LMA Supreme, i-gel, and Baska Mask for Airway Management during Laparoscopic Cholecystectomy: A Prospective Randomized Comparative Study from North India.

Background: The supraglottic airway device (SAD) has proved to be an appropriate alternative to endotracheal intubation in laparoscopic surgeries owing to various advantages, namely, decreased airway manipulation and stable hemodynamics.

Aims: We compared the efficacy in terms of oropharyngeal leak pressure (OLP) and safety of laryngeal mask airway (LMA)-Supreme (LMA-S), i-gel, and Baska mask in patients undergoing laparoscopic cholecystectomy.

Settings and design: Ninety patients posted for elective laparoscopic cholecystectomy were selected for a prospective randomized comparative study in a tertiary care center.

Materials and methods: The study comprised three groups of 30 each based on the different SADs used Group-LS with LMA-Supreme, Group-IG with i-gel, and Group-BM with Baska mask. The secondary objectives were device insertion time, ease of insertion, changes in the peak airway pressure (PAP), heart rate, mean arterial pressure, and airway complications (sore throat, dysphagia. dysphonia, lip/tongue or dental injury, etc.) between three groups.

Statistical analysis: The quantitative data were analyzed using the one-way analysis of variance test and Bonferroni post hoc multiple comparison test. Qualitative data were compared using Chi.squared test.

Results: OLP was significantly higher (P = 0.005) in the Baska mask than i-gel and LMA-S groups just after insertion and during carboperitonium. There was no significant difference in time for device insertion, number of attempts, ease of insertion, and use of manipulation (P > 0.05). However, the gastric tube insertion time was significantly lower in Group BM (9.59 ± 2.78) than Group IG with 12.79 ± 3.47 and Group LS with 10.84 ± 3.68 (P < 0.05). There were no significant differences between the groups with regard to changes in the PAP, heart rate, mean arterial pressure at different time intervals, and complications.

Conclusion: Baska mask provided a significantly higher OLP compared to i-gel and LMA-S without significant airway morbidity in laparoscopic surgeries.
