ICU Advantage - Intubation Lecture Notes

Introduction

  • Presenter: Eddie Watson
  • Platform: ICU Advantage
  • Objective: To simplify complex critical care subjects, particularly airway management through intubation in ICU.

Overview of Intubation

  • Definition: Intubation involves inserting a flexible tube (endotracheal tube) through the vocal cords into the trachea.
  • Methods:
    • Orotracheal (through the mouth)
    • Nasotracheal (through the nose)
  • Purpose: To ensure open airway and control ventilation and oxygenation.
  • Tools: Ventilator or bag valve mask.
  • Benefits: Control over breath volume, frequency, and oxygen percentage. Protects airway from aspiration.
  • Risks: Invasive and uncomfortable, potential complications discussed further.

Indications for Intubation

  1. Respiratory Failure
    • Types: Hypercapnic, hypoxic, or mixed.
    • Conditions: Need for CO2 clearance, high oxygen levels for hypoxia.
    • Note: Non-invasive support may not always be sufficient.
  2. Decreased Mental Status
    • GCS ≤ 8 indicates need for intubation.
    • Common in brain injury, strokes, overdoses.
  3. Medical Procedures
    • Require sedation or anesthesia affecting consciousness and airway protection.
    • Examples: EGDs, TEE, bronchoscopy.
  4. Airway Issues
    • Injury, swelling, edema threatening airway integrity.
    • Includes trauma to face/neck/chest.
  5. Aspiration Risk
    • Inability to clear airway or bleeding risks (trauma, varices, epistaxis).
  6. Apnea
    • Absence of breathing due to overdose, brain injury.

Contraindications for Intubation

  • Patient Wishes: Against intubation as per code status.
  • Physical Obstructions: Trauma or foreign body blocking safe tube passage.
  • Cervical Spine Fractures: Special caution needed.
  • Alternative Methods: Surgical airway (trach, crike) if intubation is not safe.

Complications of Intubation

  • Failed Intubation: Difficulty due to anatomy, obstruction or practitioner's skill.
  • Esophageal Intubation: Medical emergency requiring immediate action.
  • Pulmonary Aspiration: Risk until tube is placed and cuffed.
  • Physical Complications: Laryngospasm, bleeding, vocal cord damage.
  • Infection Risk: Ventilator Acquired Pneumonia (VAP).
  • Tube-Related Injuries: Cuff pressure, long intubation complications.
  • Patient Discomfort: Sedation often required, risks of delirium.

Conclusion

  • Preparation & Knowledge: Essential to manage intubation risks.
  • Next Steps: Future lessons will cover the intubation process.
