Background The L aryngeal M ask A irway ( LMA ) ProSeal TM and the i‐ G el TM are two extraglottic devices with either an inflatable cuff or a non‐inflatable cuff. Aim We test the hypothesis that oropharyngeal leak pressure and fiberoptic position of the airway tube differ between the size 2 LMA ProSeal TM and the i‐ G el TM in non‐paralysed ventilated children. Methods Fifty‐one children aged 1.5–6 years weighing 10–25 kg were studied using a crossover design. Anaesthesia was with remifentanil/propofol mixture. The LMA ProSeal TM and the i‐ G el TM were inserted into each patient in random order. Results Oropharyngeal leak pressure for the LMA ProSeal TM and the i‐ Gel TM was similar at 22 (5) and 21 (5) cm H 2 O, respectively. Fiberoptic position of the airway tube for the LMA ProSeal TM and the i‐ G el TM was similar, with the vocal cords visible from the distal airway tube in 94% and 96%, respectively. Conclusion We conclude that oropharyngeal leak pressure and fiberoptic position of the airway tube are similar for the size 2 LMA ProSeal TM and i‐ G el TM in non‐paralysed ventilated children.
