Prevention of aspiration under general anesthesia by use of the size 2½ ProSeal^TM laryngeal mask airway in a 6‐year‐old boy: a case report

Abstract

We report a case where use of the size 2 1/2 ProSeal laryngeal mask airway helped to prevent pulmonary aspiration of regurgitated gastric fluid. We describe the management of this case and discuss the potential advantages of this modified laryngeal mask airway for supraglottic airway management in pediatric patients.

An update on newer pediatric supraglottic airways with recommendations for clinical use

“…Second‐generation devices typically provide a better ‘second seal’ which can support higher airway pressures than first‐generation devices. The improved airway seal with the added gastric access channel helps reduce the risk of gastric insufflation, allows for more effective positive pressure ventilation (PPV), and offers some protection against unexpected regurgitation and aspiration .…”

The design of the perfect pediatric supraglottic airway device

“…Second‐generation devices of both older (Laryngeal Mask Airway ProSeal) and newer (Laryngeal Mask Airway Supreme, i‐gel, Ambu AuraGain) models have all shown to easily facilitate the insertion of an orogastric drain through the SGA's gastric channel outlet . There have been case reports and opinions by some clinicians that a second‐generation device allows them to spot regurgitation sooner (since they see it coming out of the gastric outlet), compared to using a first‐generation SGA . Due to the very low risk of pulmonary aspiration with the use of SGAs, it cannot be determined which second‐generation device is most superior.…”

Klinischer Einsatz der ProSeal®-Kehlkopfmaske bei Säuglingen, Kindern und Jugendlichen

“…In einer Reihe von klinischen Studien an Säuglingen, Kleinkindern und Schulkindern konnte nachgewiesen werden, dass die PLMA höhere p leak -Werte als die CLMA aufweist und einen zuverläs-sigen Zugang zum Magen erlaubt [5,6,8,11]. Darüber hinaus gibt es Hinweise, dass die PLMA -bei korrekter Positionierung -eine pulmonale Aspiration regurgitierten Magensekrets zu verhindern vermag [7,9,10].…”
