Comparison of oropharyngeal leak pressure of LMA Protector and LMA ProSeal in anaesthetised paralysed patients - A randomised controlled trial.

Background And Aims: In the present study, we hypothesised that the laryngeal mask airway (LMA) Protector would provide higher oropharyngeal leak pressure (OLP) than LMA ProSeal. Thus, we planned this study to compare the clinical performance of LMA Protector and LMA ProSeal in terms of OLP as a primary objective and insertion characteristics as secondary objectives.

Methods: Ninety patients of either gender, aged 18-70 years, were randomised into groups PS (LMA ProSeal) and (LMA Protector).
