To compare Proseal laryngeal mask airway & supreme laryngeal mask airway as ventilatory devices

Abstract

Background: The present study was conducted to compare Proseal laryngeal mask airway (PLMA) and Supreme laryngeal mask airway (SLMA) as ventilatory devices during general anaesthesia. Materials & Methods: The present study was conducted on 30 patients of both genders undergoing elective surgery. Patients were divided into 2 groups of 15 each. Group I patients were given Proseal laryngeal mask airway and group II were given supreme laryngeal mask airway. In both groups, insertion times, number of insertion attempts, Haemodynamic response to insertion, ease of insertion of airway device and gastric tube, oropharyngeal leak pressure (OLP) and pharyngolaryngeal morbidity were assessed. Results: In group I (cm H2O), OLP1 was 34.2 and in group II was 28.4, OLP2 in group I was 34.2 and in group II was 28.5, OLP3 in group I was 34.3 and in group II was 28.6. The difference was significant (P
