Background and Aims: The ProSeal™ laryngeal mask airway (PLMA) has a soft cuff which tends to fold on itself during insertion, resulting in reduced first-attempt success rate. We compared the standard introducer technique of PLMA insertion with a novel method to prevent folding of the cuff using a Rüsch™ Stylet Methods: This randomised superiority trial included 120 American Society of Anesthesiologists I–II patients between 18 and 80 years, undergoing elective surgeries under general anaesthesia using a PLMA for airway management.The PLMA was inserted using the standard introducer tool in sixty patients (Group IT), while in sixty other patients, a Rüsch™ Stylet was inserted through the drain tube up to its tip. (Group ST). The primary outcome was first-attempt success rate. Secondary outcomes included overall insertion success, number of attempts, total time to successful insertion, presence of air leaks, haemodynamic response to insertion and quality of fit assessed using Brimacombe's fibre-optic scoring. Continuous variables were compared using independent t-test or Mann–Whitney U-test and categorical variables were analysed using Chi-square test or Fisher's exact test. Results: First-attempt success rate of insertion was higher in Group ST compared to Group IT (95% vs. 82%, P= 0.04). Favourable grade of placement was better in Group ST (86.7% vs. 52.5%, P< 0.001). Overall insertion success rates and haemodynamic responses were comparable between the groups. Conclusions: PLMA insertion using the stylet tool has a higher first-attempt insertion success and superior placement compared to insertion using the conventional introducer tool.
