INTRODUCTION: Supraglottic airway devices with facility for gastric suction such as Proseal LMA and I gel have been successfully used for positive pressure ventilation in laparoscopic surgeries. Baska mask, a novel device with many unique features such as self-sealing membranous cuff and effective sump drainage system was designed in such a way that the perilaryngeal seal increases incrementally with increasing airway pressures. But Baska mask was not extensively evaluated to validate its use in laparoscopic surgeries.
Aim: The efficiency of Baska mask (B), Proseal LMA (P) and I Gel (I) are compared during positive pressure ventilation in laparoscopic cholecystectomy.
METHODS: Ninety patients of ASA physical status I-II planned for laparoscopic cholecystectomy were randomized into three groups (B, I, P) of 30 each. The study was proceeded with 88 (B-30, I-29, P-29) patients. Oropharyngeal leak pressure, insertion time, effective airway time and airway morbidity were assessed and compared between the three groups. Mean, Standard deviation, Paired sample t-test, one way ANOVA with Tukey's Post-Hoc test was used to analyse the data.
RESULTS: The oropharyngeal leak pressure at insertion time was 38.33 ± 4.353 cm of H2O for group B, 30.57 ± 2.174 cm of H2O for group I, 29.36 ± 2.706 cm of H2O for group P. The leak pressure was a statistically significant between group B and other groups.
DISCUSSION AND CONCLUSION: Baska mask provided higher oropharyngeal leak pressure in comparison to other two supraglottic devices.
