isolate the glottis opening between an oropharyngeal cuff and an esophageal cuff
Like the Combitube, the King LT is designed for blind placement and has a large proximal cuff and small distal cuff.Unlike the Combitube, the tip of the King LT is designed to be placed into the esophagus only.The shape of the King LT and the size of the tip make it unlikely to be placed into the trachea.
Indications~CombitubeContraindicationsrelatively: foreign body upper airway obstruction
Placement of the King LT1st step: choose the proper size King LT available only in adolescent and adult sizes size 3: yellow, 4-5 feet in height size 4: red, 5-6 feet in height size 5 designed for patients >6 feet in height.Check the cuffs and then completely deflate them prior to placementLubricate the device with a water- based lubricant.best patient position: sniffing position
Placement of the King LTHold the LT at the connector with the dominant hand and hold the mouth open by grasping the chin with the nondominant hand.Introduce the tip of the device into the corner of the mouth while rotating the tube 45°-90° so that the blue orientation line on the tube is touching the corner of the mouth.Pass the tip of the device into the mouth and under the tongue.
Placement of the King LTAs the tip passes under the base of the tongue, rotate the tube back to the midline so that the blue orientation line faces the ceiling.advance the King LT until the connector is aligned with the teethInflate the cuffs with the minimum volume necessary to create a good seal.Ventilate with a bag-valve system and confirm placement with chest rise, breath sounds, and capnography.
