A randomized comparison of the i‐gel^™ with the self‐pressurized air‐Q^™ intubating laryngeal airway in children

Abstract

Our results showed that the i-gel had easier insertion and better sealing function, and the air-Q SP provided improved fiberoptic views in children requiring general anesthesia.

A randomized comparison of volume- and pressure-controlled ventilation in children with the i-gel

“…The oropharyngeal leak pressure is consistent with previous studies reporting 21 to 26 cm H 2 O. [12–14] In comparison, gastric insufflation was presented in 20.6% of patients in our study, which is higher than in a study by Kim et al (9%) [13] but lower than observed in another study by Kim et al (30%). [14] This discrepancy might be related to the detection period.…”

“…Gastric insufflation was detected on US in 3 of that 8 cases. In most studies, including our study, [13,14,20] ventilation was acceptable in grade 3/4, but increased PIP following grade worsening may induce gastric insufflation and oropharyngeal leakage during PPV. [4,6] If there is no room for the escape of air outside the oral cavity, leaked oropharyngeal gas can be forced into the stomach.…”

“…[4] In several studies investigating the fiberoptic bronchoscopy position of the i-gel, grade 3 (only visible epiglottis) or 4 (vocal cords were not visible) was found in 10% to 40% of subjects. [13,14,20] Although it is considered that the flattened stem of i-gel improves its stabilization and prohibits its malposition, a manipulation could be required often to maintain stability of this device. [24] And also, i-gel can be displaced after postural change as in a caudal block.…”

“…[14] This discrepancy might be related to the detection period. In these previous studies using i-gel without a gastric tube, [13,14] gastric insufflation was detected by auscultation at the time of leak pressure measurement. In most studies measuring oropharyngeal leak pressure of the SGAs in children, the adjustable pressure-limiting valve was set at 30 to 40 cm H 2 O with a gas flow of 3 L/min.…”

Interdisziplinär konsentierte Stellungnahme zum Atemwegsmanagement mit supraglottischen Atemwegshilfen in der Kindernotfallmedizin

“…Hier besteht der den larynxumschließende Anteil aus einem thermoplastischen Elastomer, das durch Körperwärme weicher wird und sich somit der jeweiligen Anatomie anpasst. Diese findet auch bei Kindern zunehmend Einsatz[19,24,33], Studien zur i-gel® sind im Folgenden aber noch nicht berücksichtigt. Ein aus der klinischen Praxis häufig berichtetes Problem scheint die spontane Dislokationstendenz zu sein, die in weiteren Kinderstudien noch evaluiert werden muss.Abgewinkelte, gebogene LM mit vorgeformter L-Form (z.…”
