“A COMPARATIVE CLINICAL STUDY OF PROSEAL LARYNGEAL MASK AIRWAY VERSUS AMBU AURA GAIN FOR INSERTION PARAMETERS AND AIRWAY DYNAMICS IN LAPAROSCOPIC CHOLECYSTECTOMY PATIENTS. ”

Background: Supraglottic airway devices are now routinely used in patient posted for surgery under general anaesthesia for obvious reason of stable hemodynamics and better outcome. The ProSealTM laryngeal mask airway has a modied cuff to improve the seal and a drain tube whereas Ambu® AuraGainTM (Ambu, Ballerup, Denmark), a relatively novel supraglottic airway device is integrated with gastric access and intubation capability. 66 patients posted for surgeries under general anaesthesia were Material and methods: enrolled for the study after clearance from institutional ethical committee. Patients of group A: received Proseal and group B received Ambu aura gain(AAU). Anesthesia technique was standardized. Ease of insertion, Number of attempt, Insertion time, Oropharyngeal seal pressure, Initial peak airway pressure, Peak airway pressure after insufations, Pharyngolaryngeal adverse events and Hemodynamic parameters were recorded. Demographic prole in Results: both the groups was comparable. The ease of device insertion was more smooth in PLMA than AAU group (p=0.042). The mean time taken for insertion of AAU was longer than PLMA p=0.007. mean oropharyngeal seal pressure was signicantly more in AAU than PLMA group. Whereas no of attempts, initial peak airway pressure (cm H2O), peak airway pressure after insufations (cm H2O), complications and hemodynamics were comparable in both the groups. Present study recommends that both Ambu Aura Gain and Conclusion: Proseal LMA can be effectively used in elective laparoscopic cholecystectomies under general anaesthesia.
