Abstract

Introduction: Baska mask is a 3rd generation Supraglottic Airway Device (SGA). One of the major limitations of the SGA device is the risk of aspiration. Aim of the study: Evaluate the advantages of Baska mask over Proseal LMA in providing adequate laryngeal seal and ease of insertion. Materials and methods: A Randomized prospective single-blinded study. A study group of 40 female patients recruited and divided into 2 groups. Group I (BM-Baska Mask) with 20 patients and Group II (PLM- Proseal LMA) with 20 patients. All patients received general anesthesia with control ventilation. SGA device insertion was done once patients were anesthetized. Baseline intraoperative hemodynamic parameters and capnography were monitored. The ease of insertion was assessed by a number of attempts, time of insertion and any extra maneuver required. The airway pressure calculated as the plateau pressure with fresh gas flow at 6L and APL valve at 70cm H20. In Proseal LMA it was calculated using a handheld manometer. Results: The success rate of insertion was comparable in 2 groups. The mean time for insertion was 13.3 s while it was 19.7s for PLMA (Pvalue of 0`001). The mean airway sealing pressure was significantly higher in the BM group (p= 0.000). The seal pressure ranged from 20 -29 and 24 -37 in group I and II respectively with P value of 0.001 which makes it significant. There was no significant post-operative laryngopharyngeal morbidity in both groups. Conclusion: Baska mask provides an adequate seal with better ease of insertion when compared to Proseal LMA.
