Endotracheal Intubation

Airway · Anesthesia/ICU · 5–10 min

Placement of a cuffed tube through the vocal cords into the trachea for controlled ventilation and airway protection.

Indications

  • Respiratory failure
  • Airway protection (GCS ≤ 8)
  • Cardiac arrest
  • Anticipated deterioration
  • General anesthesia

Contraindications

  • No absolute; caution in unstable C-spine, difficult airway

Equipment

  • Laryngoscope + blades (Mac 3–4)
  • ETT 7.0–8.0 (F) 7.5–8.5 (M) + stylet
  • 10 mL syringe
  • Bougie
  • Suction (Yankauer)
  • ETCO2 detector
  • BVM + O2
  • Rescue: LMA, cricothyrotomy kit
  • Drugs: induction + paralytic

Positioning

  • Sniffing position; ear-to-sternal notch alignment; ramp obese patients.

Consent

Step-by-step (0/7)

Tap to complete

1. Pre-oxygenate

100% O2 × 3 min or 8 vital-capacity breaths.

Pearl: Apneic O2 via NC 15 L/min extends safe time

2. Prepare

3. Induce & paralyze

4. Laryngoscopy

5. Pass tube

6. Confirm

7. Secure

Immediate complications

  • Esophageal intubation
  • Right mainstem
  • Hypoxia
  • Dental trauma
  • Vocal cord injury
  • Aspiration
  • Hemodynamic collapse

Delayed complications

  • Sore throat
  • Subglottic stenosis
  • VAP

Recognition

  • No ETCO2
  • Unilateral breath sounds
  • Falling SpO2

Initial management

  • Withdraw & re-attempt
  • Reposition if mainstem
  • Call for help early

Prevention

  • Pre-oxygenate
  • ETCO2 confirmation
  • Bougie use
  • Check depth

Post-procedure observation

  • Continuous SpO2, ETCO2
  • Sedation/analgesia titration

Monitoring

  • Cuff pressure q4h
  • ETT position on CXR

Documentation

  • Grade of view (Cormack-Lehane)
  • Attempts
  • Drugs used
  • Depth

Patient instructions

  • Confirm placement on transfer
