A Comparative Study Of Baska Mask And Proseal Laryngeal Mask Airway For General Anaesthesia With Intermittent Positive Pressure Ventilation

Abstract

Background: Supraglottic airway devices (SGADs) are fundamental to non-invasive airway management during general anaesthesia, providing effective ventilation with a low incidence of complications. The Baska Mask (BM) and ProSeal Laryngeal Mask Airway (PLMA) are two widely used second-generation SGADs. This study aimed to compare the efficacy and safety of these devices by evaluating parameters such as airway sealing pressure, haemodynamic stability, ease of insertion, and postoperative complications.

Methods: In a randomized comparative study, patients undergoing general anaesthesia with intermittent positive pressure ventilation (IPPV) were assigned to either the Baska Mask or ProSeal LMA group. The primary outcomes evaluated included oropharyngeal leak pressure (OLP), insertion success rate, time to insertion, haemodynamic responses, and post-insertion morbidity.

Results: The Baska Mask demonstrated a significantly higher oropharyngeal leak pressure (OLP) compared to the ProSeal LMA. It also exhibited a shorter insertion time and required fewer manipulations to achieve proper placement. Both devices provided effective ventilation, but the Baska Mask was associated with a lower incidence of postoperative sore throat and pharyngeal morbidity. Hemodynamic stability was found to be comparable between the two groups.

Conclusion: The Baska Mask offers superior sealing efficiency, ease of insertion, and reduced postoperative complications compared to the ProSeal LMA. While both devices are effective for airway management under general anaesthesia, the choice of device should be based on a comprehensive assessment of patient characteristics, procedural needs, and the anaesthetist's clinical judgment.
