Comparative study of safety of Baska mask and Proseal LMA with respect to the oropharyngeal seal in a tertiary centre

Abstract

Background: Traditionally, endotracheal intubation has been the standard practice for administering general anaesthesia for most of the surgeries. Now a number of supraglottic airway devices (SAD) have been introduced in the clinical practice offering a simple and effective alternative to the endotracheal intubation, avoiding the use of laryngoscope to put the ETT (endotracheal tube) which is associated with exaggerated hemodynamic response. Method: The present prospective comparative study was conducted in the Department of anaesthesiology and Intensive Care, Government Medical College, Jammu. After attaining approval of the Ethical committee of the Institute, present study included 90 patients of either gender ranging from 18 – 70 years, belonging to ASA grade I and II scheduled for elective surgery of less than 2 hours duration under general anaesthesia. Patients were randomly allocated into Group P (PLMA) &Group B (Baska mask) of 45patients in each group. Result: Mean oropharyngeal leak pressure for Group P and Group B was almost equal (30.1 ± 3.08 cm H 2 O vs 30.7 ± 2.59 cm H 2 O after 5 minutes and 30.4 ± 3.09 cm H 2 O vs 31.6 ± 2.55 cm H 2 O after 30 minutes of device placement respectively). Conclusion: Oropharyngeal seal provided by the Baska mask is comparable with that of Proseal LMA with no difference in postoperative oropharyngeal morbidity.
