14King LTS-D Description
- King LTS-D consists of a curved double-lumen tube
with separate pathways for ventilation/access to
stomach - Ventilation lumen-
- ends between two inflatable cuffs with a variety
of openings to align with the laryngeal inlet - Has a 15 mm connector for attachment to
resuscitation bag or ventilator circuit - Gastric lumen-
- Separate conduit which will allow passage of up
to 18 Fr standard gastric tube
15King LTS-D Indications for use
- This device (per MIEMSS protocols) is intended
for - Patients requiring an artificial airway who have
failed direct laryngoscopy without a gag reflex
16King LTS-D Benefits
- Latex Free
- Provides the ability to provide positive pressure
ventilation as well as allowing spontaneous
breathing - Seal Pressure gt 30 cm H20
- Ease of Insertion
- Low incidence of sore throat/trauma
- Minimizes gastric insufflation
- Allows for easy passing of a gastric tube via the
gastric access lumen
17King LTS-D Warnings/Precautions
- Not proven to protect the airway from the effects
of regurgitation/aspiration - High airway pressures may divert gas to the
atmosphere - Intubation of the trachea cannot be ruled out as
a potential complication - After placement, perform standard checks for
breath sounds/utilize appropriate CO2 - Lubricate only the posterior surface of the King
LTS-D to avoid blockage of the ventilation
apertures or aspiration of lubricant - Single use only
18King LTS-D Contraindications
- Responsive patients with an intact gag reflex
- Patients with known esophageal disease
- Patients who have ingested caustic substances
- Patients lt 35 inches (per MIEMSS protocols)
