Kleine–Brueggeney M, et al. – This study provides a comparative assessment of the performance of the pediatric LMA Supreme, Air–Q and Ambu Aura–i. Findings demonstrated that airway leak pressures ranged from 16 to 18 cmH₂O, enabling positive pressure ventilation with all successful supraglottic airway devices (SGA). The LMA Supreme provided the highest success rates and was also rated easiest to insert.
