Baska Mask is non-inferior to tracheal tube in preventing airway contamination during controlled ventilation in elective nasal surgeries: A randomised controlled trial

Abstract

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.

Safety and Efficacy of the Baska Mask Versus Endotracheal Intubation in 64 Women Undergoing Elective Laparoscopic Gynecological Surgery Under General Anesthesia: A Prospective Single-Center Study

“…A previous study reported that the Baska mask demonstrated a level of utility comparable to that of SAD. Many studies have also been conducted to evaluate the effectiveness of the Baska mask compared to other airway devices [ 7 – 9 , 17 – 24 ]. In most studies, the Baska mask was considered an appropriate SAD for maintaining stable hemodynamics, effective tidal volume, and suitable airway pressures.…”

Recent advances in airway management

“…Along with this, it has been equipped with a gastric reflux high-flow suction clearance system. [ 27 ] Another inclusion is the LMA protectorÔ. Distinct from other SADs, it contains two gastric drainage channels and a pharyngeal chamber to drain the gastric contents.…”

Airway management considerations in patients with vocal fold implants

“…The most interesting is the advances in the supraglottic airway devices with enhanced protection against aspiration which may be comparable to the ETT (51). In the management of patients with VFI, using these devices would avoid contact with the implant.…”
