A Prospective Randomized Study Comparing Fiberoptic Bronchoscope Endotracheal Intubation Between the Intubating Laryngeal Tube Suction and the LMA Protector

Detailed Description: Securing the airway is a pivotal skill for anesthesiologist and emergency providers. Endotracheal intubation (ETI) is considered the gold standard for securing the airway. Induction time during anesthesia may sometimes present unexpected difficulties during ETI.

When ETI via laryngoscopy has failed, the use of a supraglottic airway device (SGAD) has been recommended. Previous studies suggested that compare intubation with laryngoscope, SGADs enables rapid and effective airway control. Improved second generation SGADs enable ventilation and oxygenation, but also include a second channel that separates the trachea from the esophagus preventing aspiration. According with the results of the Fourth National Audit Project of the Royal College of Anesthetist will bets and the Difficult Airway Society, the second generation SGADs should be uses instead the first generation.

Some of the second generations of SGADs have a ventilation channel that allow the insertion of an endotracheal tube.

Two of these devices recently introduced in the market are the intubating Laryngeal Tube Suction Disposable (iLTS-D) and the Laryngeal Mask Airway Protector [5, 6] The intubating Laryngeal Tube Suction- Disposable (iLTS-D) (VBM, Germany) is a new updated version of the Laryngeal Tube-Suction Disposable (LTS-D). [5] It has a ventilator channel with a 13.5mm internal diameter, which enables the passage of an Endotracheal Tube (ETT) No 7.5 mm. for fiberoptic guidance. Similarly to the LTS-D, the iLTS-D also has a separate channel for gastric tubes placement up to a size of 18 Fr. The device is latex free, made of PVC, and like the original laryngeal tube (LT), can be inserted blindly.

The iLTS-D comes in one size. According to the depth of insertion, the device will be equivalent to size 4 for patients 175 to 190 cm tall, or size 5 for patients taller than 190 cm.
