“…have addressed this issue by attaching two 12-Fr Tri-Flo suction catheters to the distal barrel of the flexible LMA on the posterior surface. [ 14 ] With this modification, they were able to prevent post-extubation complications even in patients with significant intra-operative bleeding. The BM supraglottic airway, has an inbuilt provision for performing the same function.…”

Background and Aims: Baska Mask, a newly designed third-generation supraglottic device, has a sump where the pharyngeal secretions can collect and be suctioned out continuously. We aimed to study the effectiveness of Baska Mask in preventing airway contamination during nasal surgeries. Our primary objective was to assess airway soiling using fibreoptic bronchoscopy. Total airway manipulation time, haemodynamic parameters during device insertion and post-operative oro-pharyngeal morbidities were the secondary objectives. Methods: Eighty-four participants undergoing nasal surgeries were randomised to either have their airway maintained with Baska Mask (Group-BM) or Endotracheal tube (Group-TT). Fibreoptic bronchoscopy was performed at the end of the surgery and the airway was inspected for signs of contamination. Total airway manipulation time, haemodynamic parameters during device insertion and post-operative oro-pharyngeal morbidities were also assessed. Unpaired Student's t test was used for parametric data and Chi-square test for nonparametric data. One-way analysis of variance (ANOVA) was used for the intra-group analysis of haemodynamic data. Results: Tracheal contamination was not observed in any patient in either group. Time taken for device insertion (Group TT: 24.24 ± 6.86 s vs. Group BM: 24.22 ± 7.3 s; P = 0.97) was similar in both the groups. The total airway manipulation time was 2 min longer in Group-TT ( P = 0.000) due to additional time taken for insertion of throat pack. Haemodynamic parameters during device insertion were stable and post-operative oro-pharyngeal morbidities were fewer with Baska Mask when compared to Tracheal tube. Conclusions: Baska Mask is non-inferior to tracheal tube in preventing tracheal contamination in patients undergoing nasal surgeries.
