The Laryngeal Tube Suction-Disposable (LTS-D, (VBM Medizintechnik GmbH, Sulz, Germany), is a second generation single-use supraglottic airway devices (SADs) with gastric access, for airway management in spontaneously and mechanically ventilated patients undergoing general anesthesia.~The AuraGain is a second generation laryngeal mask, satisfying airway management needs by integrating gastric access and ventilation capability in an anatomically curved single-use device that facilitates rapid establishment of a safe airway.~The two devices have now pediatric sizes.~To date, there is no published data comparing the LTS-D and the DLMA AG during mechanical ventilation in pediatric patients. The investigators hypothesized that the LTS-D and the DLMA AG perform similarly during mechanical ventilation despite differences in their structural design.~The chief aim of this prospective randomized study was to compare the LTS-D and the DLMA AG with respect to:~time to achieve an effective airway,~ease of insertion,~need for interventions to achieve an effective airway,~cuff seal (leak) pressure at an intracuff pressure of 60 cm H2O,~ventilatory variables during mechanical ventilation,~fiberoptic score,~gastric tube insertion and~adverse perioperative events.
The study compared the Laryngeal Tube Suction Disposable (LTS-D) with the Disposable Laryngeal Mask Ambu® AuraGain™ (DLMA AG) during general anesthesia in pediatric patients.~The investigators hypothesized that the LTS-D and the DLMA AG performed similarly during mechanical ventilation despite differences in their structural design.
