I‑gel versus Air‑Q airway devices for children aged 1–10 during general anesthesia
Effect of I-gel and Air-Q SP LMAs on Oropharyngeal Leak Pressure and Gastric Insufflation in Children: An Ultrasonography-Guided Randomized Study
This test compares I‑gel and Air‑Q to see which is easier to place, gives a better airway seal, and causes less air in the stomach for children aged 1–10 having general anesthesia.

What this trial studies
Children aged 1–10 undergoing elective surgery with planned supraglottic airway use will receive either an I‑gel or an Air‑Q device during general anesthesia. Clinicians will record insertion ease and speed, measure airway seal quality, and use ultrasound to check device position and detect gastric insufflation. All procedures fall within routine anesthesia practice and ultrasound provides a noninvasive way to detect stomach air. The results will compare practical performance and safety measures between the two commonly used pediatric airway devices.
Who should consider this trial
Good fit: Children aged 1–10 years with ASA physical status I–II scheduled for elective surgery under general anesthesia where a supraglottic airway is planned and whose parent or guardian provides consent.
Not a fit: Children with predicted difficult airways, significant pulmonary disease, gastroesophageal reflux, morbid obesity, emergency surgery, or prior complications with supraglottic devices are excluded and unlikely to benefit from the study results.
Why it matters
Potential benefit: If one device shows clearer advantages, clinicians could choose that device to reduce airway problems and unwanted air entering the stomach during pediatric anesthesia.
How similar studies have performed: Similar device-comparison work has been performed in children and adults, with some reports favoring I‑gel for faster insertion and better seal but overall results have been mixed across settings.
