Indications
- Failure to ventilate
- Failure to oxygenate
- Inability to protect airway (gag unhelpful)
- Anticipated clinical course (anticipated deterioration, transport, or impending airway compromise)
- Increased ICP (for hyperventilation)
- Combative, needing imaging
Difficult BVM (MOANS)
- Mask seal
- Obesity
- Aged
- No teeth
- Stiffness (resistance to ventilation)
"Remove dentures to intubate; keep them in to bag/mask ventilate"
Difficult Intubation
- Look externally (gestalt)
- Evaluate 3-3-2 rule
- Mallampati
- Obstruction
- Neck mobility
Severe Metabolic Acidosis
- Further drop in pH during intubation can be catastrophic
- NIV (SIMV Vt 550, FiO2 100%, Flow Rate 30 LPM, PSV 5-10, PEEP 5, RR 0)
- Attach end-tidal CO2 and observe value
- Push RSI:Rapid Sequence Intubation (RSI) meds
- Turn the respiratory rate to 12
- Perform jaw thrust
- Wait 45sec
- Intubate
- Re-attach the ventilator
- Immediately increase rate to 30
- Change Vt to 8cc/kg
- Change flow rate to 60 LPM (normal setting)
- Make sure end-tidal CO2 is at least as low as before
GI Bleeder
- Empty the stomach
- Place an NG and suction out blood
- Varices are not a contraindication
- Metoclopramide 10mg IV
- Increases LES tone
- Place an NG and suction out blood
- Intubate with HOB at 45°
- Consider Glidescope
- Preoxygenate!
- Want to avoid bagging if possible
- Intubation meds
- Use sedative that is BP stable (etomidate, ketamine)
- Use paralytics (actually increases LES tone)
- If need to bag:
- Bag gently and slowly (10BPM)
- Consider placing LMA
- If pt vomits place in Trendelenberg
- If pt aspirates anticipate a sepsis-like syndrome
- May need pressors, additional fluid (not abx!)
Nasal Intubation
- sniffing position (like oral ET)
- pretreat with lido, hurricaine, or 4cc nebulized lidocaine for 5 minutes
- Tube size = 1.0 mm smaller
- listen with stethoscope at end of tube (breath sounds become louder as tube approaches cords)
- when tube hits cords patient will cough, back up 1 or 2 cm. wait for beginning of inspiration, as patient begins inspiration advance 3-4 cm (tube should be 22-26cm in women, 23-28cm in men)
tips: occlude other nostril to hear better, cricoid pressure when advancing, use a small suciton catheter as a seldinger guide, precurve tube before insertion.
