Abstract

Background: Supraglottic devices have revolutionized the airway management by providing the patent airway without endotracheal intubation. Proseal LMA has gastric drainage tube along with dorsal and ventral cuff. The Baska Mask® have membrane instead of cuff which inflates on every breath during Positive Pressure Ventilation (PPV). Aim: to compare BASKA mask and Proseal LMA in terms of safety and efficacy during positive pressure ventilation. Subjects and Methods: Settings and Design: Prospective, randomized, interventional study was conducted in 100 patients following approval by the Board of Studies and Ethical Committee. Patients were divided in two groups of 50 each. Written informed consent was taken before taking for surgery. Baska mask and Proseal LMA were compared as ventilatory conduit to compare the time to achieve effective ventilation, oropharyngeal leak pressure, fiberoptic laryngeal view scoring by POGO (Percentage of Glottic Opening) Scoring and pharyngolaryngeal morbidity. Statistical Analysis: done with the help of SPSS version 14 and p value less than 0.05 was taken significant Results: Total time required to achieving effective ventilation (seconds) was significantly less in BM group compared to group PLA (22.2 ± 6.91 sec vs 26.36 ± 8.66 sec, P < 0.001). Mean OLP was better in group BM (32.3.5 ± 3.01 cm H2O vs 31.06 ± 2.82 cm H2O). Anatomical alignment of SGD with glottis (POGO 100 %) was similar in both the groups, the group BM (43/50) and group PLA (41/50). Laryngopharyngeal morbidity was comparable between two groups. Conclusion: Our study support that the BASKA Mask is an effective conduit, provides better seal in significantly less time compared to ProSeal laryngeal mask and could be safely use for airway management in surgical patients.
