LMA Pro SealTM vs. i- GelTM in ventilated children: A randomised, crossover study using the size 2 mask.

Background The Laryngeal Mask Airway ( LMA) ProSeal^TM and the i- Gel^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- Gel^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- Gel^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 H₂O, respectively. Fiberoptic position of the airway tube for the LMA ProSeal^TM and the i- Gel^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- Gel^TM in non-paralysed ventilated children.
