Primary Survey/Airway

  •  

    •  


🟠 2. Manual Airway Maneuvers

Assume C-spine injury in trauma.

  • Jaw thrust (preferred if C-spine not cleared)

  • Chin lift only if no C-spine concerns

  • Suction blood, vomitus, secretions

  • Remove foreign bodies if visible


🟡 3. Airway Adjuncts

➤ Oropharyngeal Airway (OPA)

  • For unconscious patients without gag reflex

➤ Nasopharyngeal Airway (NPA)

  • For semiconscious with intact gag reflex

  • Avoid if facial/basal skull fracture suspected


🟢 4. Oxygenation & Ventilation

  • Apply high-flow oxygen via non-rebreather mask

  • Use bag-valve-mask (BVM) if:

    • Apneic

    • Poor respiratory effort

    • Oxygen saturation remains low

BVM technique tip: Use two-person technique if possible (one maintains seal, the other squeezes bag)


🔵 5. Definitive Airway (if needed)

Indications:

  • GCS ≤ 8

  • Inadequate breathing

  • Inability to protect airway

  • Facial trauma, burns, or obstruction

Options in Prehospital Setting:

  • Endotracheal Intubation (ETI): If trained and allowed by protocol

  • Supraglottic Airways (e.g., i-gel, King LT, LMA):

    • Good backup or primary if ETI not feasible

  • Surgical Airway (Cricothyrotomy):

    • Last resort in "can’t intubate, can’t ventilate" scenario

    • Only performed by trained personnel


⚪ 6. C-Spine Protection Throughout

  • Apply rigid cervical collar

  • Maintain manual in-line stabilization during any manipulation

  • Immobilize the patient on a long spine board if indicated


🔁 7. Reassess Continuously

  • Recheck airway patency

  • Monitor oxygen saturation and breathing pattern

  • Prepare for deterioration (e.g., swelling from burns or trauma)

    • Establishing an airway in a trauma patient is a critical step and must be done promptly and carefully, as airway compromise is a leading cause of preventable death in trauma. Here's a systematic approach, often guided by Advanced Trauma Life Support (ATLS) principles:


      1. Initial Assessment

      • Assess responsiveness (AVPU: Alert, Verbal, Pain, Unresponsive).

      • Look, Listen, and Feel for signs of airway compromise:

      • Facial injuries, blood, vomitus, chest rise
      • Use of accessory muscles

      • Cyanosis or hypoxia

      • Listen: Stridor, gurgling, snoringsilence

      • Feel: Air movement, crepitus


      2. Airway with Cervical Spine Protection

      Since trauma patients, especially with blunt trauma, may have cervical spine injuries, always assume C-spine injury until ruled out.

      • Manual in-line stabilization (MILS) of the cervical spine should be maintained.

      • Avoid hyperextension of the neck.


      3. Basic Airway Maneuvers

      • Jaw thrust (preferred if C-spine injury suspected)

      • Chin lift (if no C-spine concern)

      • Clear the airway:

        • Suction blood, vomitus, debris

        • Remove visible foreign bodies


      4. Airway Adjuncts

      • Oropharyngeal airway (OPA): For unconscious patients without gag reflex

      • Nasopharyngeal airway (NPA): If semi-conscious or gag reflex intact (avoid in suspected basal skull fracture)


      5. Definitive Airway

      Indications for a definitive airway include:

      • GCS ≤ 8

      • Apnea or severe respiratory distress

      • Inability to protect airway (e.g., facial trauma, burns)

      • Hemorrhage compromising the airway

      Options:

      • Endotracheal intubation (oral route preferred; nasal generally avoided in trauma)

      • Rapid Sequence Intubation (RSI):

        • Preoxygenate

        • Administer induction agent and neuromuscular blocker

        • Intubate with MILS

      • Surgical airway (if intubation fails or is not feasible):

        • Cricothyrotomy (preferred in emergency)

        • Tracheostomy (rarely done emergently)


      6. Confirmation and Maintenance

      • Confirm tube placement with:

        • End-tidal CO₂ detection (gold standard)

        • Bilateral chest rise

        • Auscultation (5-point check)

      • Secure the airway

      • Continue cervical spine protection

      • Ventilate as needed


      7. Consider Special Scenarios

      • Facial trauma: May require surgical airway early

      • Burns/inhalation injury: Early intubation before airway edema worsens

      • Penetrating neck trauma: Secure airway and prepare for surgical intervention
