Airway Management with the King Airway LTD Device. By Kevin Malicky
Objectives • Understanding the description and use of King LTD. • Requirements needed for LTD use • Clinical studies involving King LTD airways • Sizes and insertion of King LTD • The overall success rate of King LTD • Minimal disadvantages to LTD use
King Airways • The KING LTD is supplied clean and is a non-sterile device • It consists of a curved tube with ventilation apertures located between two inflatable cuffs. • The distal cuff is designed to seal the esophagus • Proximal cuff is intended to seal the oropharynx
King LTD Uses • The nurse can insert the King LTD in emergency situation with minimal training. • Cardiac arrest • Respiratory distress/arrest.
Training Requirements • Quarterly training with SIM’S man on insertion of King LTD. • Annual training videos on updates for insertion. • OR time for insertion required each quarter to maintain competency.
Clinical Studies • Insertion was determined to be easy and a patent airway was achieved in all 50 patients. • Successful mechanical ventilation in 169 of 175 patients. With 3 patients unsuccessful due to high pressure volumes. • In a trial of 60 all 60 patients had the LTD inserted successfully on the first attempt.
King Airway Sizes • The King LTD is available in size 3, 4, & 5 and can be used with patients 35 inches (90 cm) and taller • Adult sizes are based on the patient's height. • Size 2 and 2.5 are only available For Pediatric. • Pediatric sizes are based on the patient’s height or weight
How do you insert a King LTD • Insert the airway until the hub is at the level of the teeth. • Inflating the cuffs • Withdrawing the KING LTD airway until ventilation is optimized results in the best depth of insertion. • No need to check for Bilateral breath sounds.
Advantages • Emergency ventilation can take place within 15 seconds without a laryngoscope. • Requires minimal movement of patient head. • Requires minimal education to insert. • The King laryngeal airway is designed to be inserted without direct visualization. • Minimal risk of aspiration. • The KING LTD provides a secure, non-intubating emergency airway when direct laryngoscopy is not feasible
Disadvantage • Only make limited sizes. • The KING LTD can be used in routine procedures only up to 8 hours. • Unable to place medication down the tube. • Trauma related to balloon in trachea.
Summary • With minimal experience the nurse can insert the King LTD. • The patient can be ventilated with a King Airway. • Minimal aspiration with a King Airway. • Patient can be intubated without a laryngoscope.
