Indications

  1. Failure to ventilate
  2. Failure to oxygenate
  3. Inability to protect airway (gag unhelpful)
  4. Anticipated clinical course (anticipated deterioration, transport, or impending airway compromise)
  5. Increased ICP (for hyperventilation)
  6. Combative, needing imaging

Difficult BVM (MOANS)

  1. Mask seal
  2. Obesity
  3. Aged
  4. No teeth
  5. Stiffness (resistance to ventilation)

"Remove dentures to intubate; keep them in to bag/mask ventilate"

Difficult Intubation

  1. Look externally (gestalt)
  2. Evaluate 3-3-2 rule
  3. Mallampati
  4. Obstruction
  5. Neck mobility

Severe Metabolic Acidosis

  • Further drop in pH during intubation can be catastrophic
  1. Ventilate (SIMV Vt 550, FiO2 100%, Flow Rate 30 LPM, PSV 5-10, PEEP 5, RR 0)
  2. Attach end-tidal CO2 and observe value
  3. Push RSI meds
  4. Turn the respiratory rate to 12
  5. Perform jaw thrust
  6. Wait 45sec
  7. Intubate
  8. Re-attach the ventilator
  9. Immediately increase rate to 30
  10. Change Vt to 8cc/kg
  11. Change flow rate to 60 LPM (normal setting)
  12. Make sure end-tidal CO2 is at least as low as before

Nasal Intubation

  1. sniffing position (like oral ET)
  2. pretreat with lido, hurricaine, or 4cc nebulized lidocaine for 5 minutes
  3. Tube size = 1.0 mm smaller
  4. listen with stethoscope at end of tube (breath sounds become louder as tube approaches cords)
  5. 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.
