Airway Management Decision Process
CONTROL THE AIRWAY Airway Management Decision Process (Judge how aggressive you need to be.) -Time/Distance -Personnel -Equipment -Other Considerations?
14
“Evaluate for signs of difficult intubation”
CONTROL THE AIRWAY “Evaluate for signs of difficult intubation” (this may help in your decision as well) -Obesity -Small body habitus -Small jaw -Large teeth -Burns -Trauma -Anaphylaxis -Stridor
15
CONTROL THE AIRWAY The PCP vs. ACP airway decision may not be based on one single factor, but rather based on an overall assessment of many factors.
16
CONTROL THE AIRWAY Pre-Intubation -Prepare Equipment -Hyper-oxygenate

24
CONTROL THE AIRWAY What is your back-up plan today? prolonged BVM…
another provider… a smaller tube… better lighting… additional suctioning…

Nasotracheal Intubation
CONTROL THE AIRWAY Nasotracheal Intubation Indications: “Patient still breathing but in respiratory failure and in whom oral intubation is impossible or difficult.”
28
Nasotracheal Intubation
CONTROL THE AIRWAY Nasotracheal Intubation Contraindications: -Apnea -Resistance in the nares -Blood clotting or anticoagulation problems -Basilar Skull Fx (?)
29
-Prepare patient and nostril -Insert on inspiration
STEP 4. CONTROL THE AIRWAY Nasotracheal Intubation Technique: -Prepare patient and nostril -Prepare tube -Insert on inspiration -Take your time Complications: -Bleeding
30
Intubation Confirmation
. CONFIRM THE AIRWAY Intubation Confirmation Good, Better, Best Traditional Direct Visualization Lung Sounds Tube Condensation Technology Based ETCO2 (monitor) EDD (bulb) Colormetric (cap) Pulse Ox change

ALTERNATIVES TO ETI Laryngeal Mask Airway Developed in 1981 at the Royal London Hospital By Dr Archie Brain
33
Not a substitute for definitive airway management
STEP 7. ALTERNATIVES TO ETI Laryngeal Mask Airway Indications: -When definitive airway management cannot be obtained. (ETT) Not a substitute for definitive airway management
34
Contraindication/Limitations:
ALTERNATIVES TO ETI Laryngeal Mask Airway Contraindication/Limitations: -Obesity -Non-secure -Size based -Not a med route
35
Laryngeal Mask Airway Weight Based Sizing <5kg = Size 1
ALTERNATIVES TO ETI Laryngeal Mask Airway Weight Based Sizing <5kg = Size 1 5-10 kg = Size 2 20-30 kg = Size 2.5 Small Adult= Size 3 Average Adult = Size 4 Large Adult = Size 5
36
*If in doubt, check the LMA
ALTERNATIVES TO ETI Laryngeal Mask Airway Average Adult Woman = 4 Average Adult Male = 5 *If in doubt, check the LMA
37
Laryngeal Mask Airway Procedure: ALTERNATIVES TO ETI -Hyper oxygenate
-Check cuff -Lubricate posterior cuff -Head in neutral or slightly flexed position -Insert following hard palate (use index finger to guide) -Stop when met with resistance -Let go and inflate cuff (visualize “pop”) -Confirm and secure
38
ALTERNATIVES TO ETI Laryngeal Mask Airway Air volume is variable depending on cuff size and individual patient anatomy General Guideline: Size 1 = 4 ml Size 2 = 10 ml Size 2.5 = 14 ml Size 3 = 20 ml Size 4 = 30 ml Size 5 = 40 ml
39
Laryngeal Mask Airway Common Provider Problems:
ALTERNATIVES TO ETI Laryngeal Mask Airway Common Provider Problems: -Failure to seat properly -Sizing difficulties -Aspiration

King Airway
41
King Airway Why Known Issues
Unconscious / unresponsive patients without gag reflex Blind insertion technique Alternative to E.T.T. Known Issues Obtaining proper seal / placement Is NOT a medication route for Endotracheal drugs Multiple sizes, based on height, also multiple cuff volumes Contraindications Responsive patients with an intact gag reflex. Patients with known esophageal disease. Patients who have ingested caustic substances.
44
User Tip The key to insertion is to get the distal tip of King Airway around the corner in the posterior pharynx, under the base of the tongue. Experience has indicated that the lateral approach, in conjunction with a chin lift, facilitates the placement of the King Airway. Alternatively, a laryngoscope or tongue depressor can be used to lift the tongue anteriorly to allow easy advancement of the airway into place.
46
Insertion #1
47
Insertion #2
48
Insertion #3 As the King Airway is advanced around the corner
in the posterior pharynx, it is important that the tip of the device be maintained at the midline. If the tip is placed or deflected laterally, it may enter into the piriform fossa and the tube will appear to bounce back upon full insertion and release. Keeping the tip at the midline assures that the distal tip is properly placed in the upper esophagus.
49
Insertion #4
50
Insertion #5 Air Volume Required for Cuff Inflation: Size #3: 55 ml
51
Insertion #6 Attach Bag While gently bagging, simultaneously withdraw the King Airway until ventilation is easy and free-flowing. Can the King tube device be used for PPV? Yes, in unresponsive non breathing pts
53
Is there an optimal head position for insertion?
Sniffing position, but the head can be in neutral position. For obese patient’s, elevation of the shoulders & upper back should be considered. How long can the King tube be left in place? Up to 8 hours. For longer procedures it is important to monitor& limit cuff pressure to 60 cm H20 or less. If my patient needs to be on a mechanical ventilator, do I need to replace the tube? Due to the King tube’s improved ventilatory seal, it is less frequent that the tube needs to be exchanged compared to other supraglottic airways. Can a laryngoscope be used? Yes, but it is not routinely used. It may be used by the inexperienced user, or difficult airway. What volume of pressure is needed to properly inflate the cuffs? The least amount needed to create a seal at the desired ventilatory pressures. Each tube size is different What reference point for the centimeter depth markings on the tubes? The cm markings indicate the distance from the distal ventilatory opening. The markings serve as a visual reference after placement and can be used to document insertion depth.
54
LAST RESORT! Indications SURGICAL AIRWAYS -Obstruction -Facial Trauma
-Intubation or other alternatives impossible -Trismus (clenching) ->8 years old (for open procedures) LAST RESORT!

Symptomatic Patients get treated electrically
Chest pain Shortness of breath Pulmonary edema Hypotension Diaphoresis Decreased LOA
65
Vagal Manuvers/CSM For stable patients with signs of clinically significant tachy rhythms CSM “Fake” the baroreceptors into thinking BP is too high so slows HR down Vagal manuvers- increase ITP to see if can stimulate a vagal response Patients <70 or with no bruits in carotid arteries
