ETT Introducer Difficult Airway Management Flashcards
What equipment is necessary for RGW -assisted intubation?
1) J-Tipped Guide wire (J-wire) 0.035”– 60 cm minimum length. 2) 2 Hemostats 3) Small diameter ETT or ETT introducer
What three techniques are used for a difficult airway or traumatically injured airway?
1)Cricothyroid puncture to obtain access 2)high-pressure oxygenation and ventilation (HPOV) 3)retrograde Guide wire- assisted endotracheal integration (RGW)
What is the primary purpose of high-pressure oxygenation and ventilation (HPOV)?
Oxygenate patient (not ventilation)
What is the life-threatening problem related to loss of upper airway patency?
Hypoxia (not hypercapnia)
What is a contraindication for HPOV technique
Complete airway obstruction
What equipment is needed for high-pressure oxygenation & ventilation (HPOV) ?
1) High-pressure small diameter oxygen supply tubing 2) Three-way stopcock (turn so that all ports are open) 3) high-pressure oxygen supply connector 4) Oxygen flow meter with nipple Or Anesthesia machine fresh gas outlet with 6mm ETT connector
What flow should be set for the HPOV technique?
Flow should be set to flush
Equipment that comes in and HPOV-RGW kit?
10 mL syringe with needle Vile lidocaine 2% 14 gauge IV catheter 0.035 flexible J-wire 60 cm longer Hemostats Alcohol prep pads Low compliance oxygen tubing Three-way stopcock Threaded nipple for oxygen flow meter 6 mm ETT connector for anesthesia machine
Which practitioner-based error accounts for the greatest percentage of “acute” errors when using HPOV technique
50% account for catheter p lacement not confirmed
What practitioner based errors account for the greatest percentage of “intermediate” errors in the HPOV technique
Inadequate oxygenation
What is special about the ETT introducer?
it has a lumen to provide HPOV
What does HPOV stand for?
High-pressure oxygenation ventilation
What is the catheter memory in the distal 2 cm of the ETT introducer?
15 – 30°
How do you know that the ETT introducer is in the trachea?
By Tactile feedback. Once the tip of the Introducer is through the glottis you will feel the bump of the tracheal rings.
What structure of the glottis must you be able to see in order to use the ETT introducer?
The epiglottis. It is used to lift the body of the epiglottis then slide into the vocal chords
