Popis: Abstract Background Supraglottic airway devices (SADs) are the mainstay for airway management in pediatric ambulatory surgeries and may often be a suitable alternative to endotracheal intubation due to their favorable profile. Optimal oropharyngeal leak pressure of SAD is essential for adequate ventilation and prevention of aspiration. Occasionally, lateral position is required for administration of regional block or for the surgery itself. We aim to compare the oropharyngeal leak pressure of igel™ and LMA Supreme™ in children in lateral position. A prospective, randomized study was performed on eighty children of either sex, weighing 5–10 kg, belonging to ASA grade I and II undergoing elective surgery requiring lateral position. The primary objective was comparison of Oropharyngeal leak pressure of both devices in lateral position. Secondary objectives included assessment of insertion success rate, number of insertion attempts and manipulations, time and ease of insertion; and comparison of fiberoptic view of the larynx, fractional volume loss, and displacement with respect to both devices in supine and lateral position. Results Oropharyngeal leak pressure of i-gel™ was higher than that of LMA Supreme™ in both supine (25.4 ± 1.4 cm H2O Vs 22.9 ± 1.5 cm H2O) and lateral position (23.9 ± 1.6 vs 21.5 ± 1.5 cm H2O) and was statistically significant (p
