Summary We compared the performance of the Intersurgical Solus TM laryngeal mask airway (LMA) with that of the i‐gel in 120 patients of ASA physical status during general anaesthesia with respect to oropharyngeal leak pressure, peak airway pressure, airway manipulation, insertion time, fibreoptic view, ventilatory parameters, and peri‐operative complications . After receiving a standardised induction of anaesthesia, either a Solus LMA (60 patients) or an i‐gel (60 patients) was inserted. One hundred and fifteen patients completed the study. The leak pressure was significantly higher in the LMA group than the i‐gel group (mean (SD) 22.7 (7.7) cmH 2 O vs 19.3 (7.1) cmH 2 O; p = 0.02). A better fibreoptic view of the larynx was obtained in patients in the LMA group (p = 0.02) compared to those in the i‐gel group and less airway manipulation was required in the LMA group (p < 0.01). Both devices have good performance with very low peri‐operative complications . However, the Solus LMA provides a better oropharyngeal seal, provides a better fibreoptic view, and requires less manipulation to secure the airway than the i‐gel.
