The investigators hypothesized that the LTSD and the DLMA AG performed similarly during mechanical ventilation despite differences in their structural design.
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:
1. time to achieve an effective airway,
2. ease of insertion,
3. need for interventions to achieve an effective airway,
4. cuff seal (leak) pressure at an intracuff pressure of 60 cm H2O,
5. ventilatory variables during mechanical ventilation,
6. fiberoptic score,
7. gastric tube insertion and
8. adverse perioperative events.

In neonatal resuscitation, laryngeal mask airway (LMA) is recommended when both face mask ventilation and endotracheal intubation fail. However, experience of LMA among obstetricians, nurses and midwi...
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
Cancers or tumors of the LARYNX or any of its parts: the GLOTTIS; EPIGLOTTIS; LARYNGEAL CARTILAGES; LARYNGEAL MUSCLES; and VOCAL CORDS.
Branches of the vagus (tenth cranial) nerve. The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. They carry efferents to all muscles of the larynx except the cricothyroid and carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
Abnormal accumulation of fluid in tissues of any part of the LARYNX, commonly associated with laryngeal injuries and allergic reactions.
