Abstract

The supraglottic airway devices are novel devices that have revolutionized airway management and have replaced endotracheal tube in anaesthesia. With the advent of newer supraglottic devices for better airway control, we are comparing efficacy of the Baska mask and LMA supreme. Setting And Design: Fifty participants posted for elective surgery under GA were selected for prospective double blinded randomized controlled study. Materials And Methods: Total of fifty participants who were undergoing elective surgery under GA of less than 60 min duration, belonging to ASA physical status 1 and II, aged 18 to 60 years were randomised into two groups. Group A: Baska mask and group B: LMA supreme. After induction with propofol 2mg/kg,fentanyl 2µ/kg and Atracurium 0.5 mg/ kg, patients were inserted with either Buska mask or LMA supreme. The efficacy is compared in terms of first-time insertion success rate, the number of attempts for correct placements, device insertion time, leak pressure, ease of insertion of gastric tube and incidence of intraoperative and postoperative complications between the two devices. Results: There was no significant difference among demographic variables between the groups. The ease of insertion was significant with 96% in group B compared to 72% in group A. Time taken for insertion also found to be significantly shorter in group B(11.88±2.56) vs group A (14.24±4.96).Oropharyngeal leak pressure was significantly higher(p<0.001) in group A than group B. There was no significant difference between the groups with regards to gastric tube insertion, intraoperative and postoperative complications. Conclusion: We conclude that, LMA supreme was found to have a better ease of insertion compared to Buska mask. The Buska mask provides higher oropharyngeal leak pressure and thus provides better airway protection compared to LMA supreme.
