What is the initial management of a patient with a history of neck trauma?

Initial Management of Neck Trauma

The initial management of a patient with neck trauma should follow a systematic approach based on clinical stability, with immediate surgical exploration for unstable patients showing hard signs, and CT angiography as the first-line imaging for stable patients without hard signs requiring immediate intervention. 1

Primary Assessment and Stabilization

• Immediate assessment using Advanced Trauma Life Support (ATLS) principles with focus on airway, breathing, and circulation 2
• Early spine immobilization for any patient with suspected spinal cord injury to limit neurological deficit progression 1
• For patients requiring intubation with suspected cervical spine injury:
  • Use manual in-line stabilization with removal of the anterior part of cervical collar during intubation 1
  • Employ rapid sequence induction with direct laryngoscopy and gum elastic bougie without Sellick maneuver 1

Clinical Evaluation and Decision Making

• Classify patients based on clinical stability and presence of "hard signs" or "soft signs" 1

Hard Signs (requiring immediate surgical exploration):

• Active hemorrhage
• Expanding hematoma
• Hemodynamic instability
• Airway compromise
• Massive subcutaneous emphysema 1

Soft Signs (requiring further evaluation):

• Non-pulsatile hematoma
• Dysphonia
• Minor subcutaneous emphysema
• Dysphagia 1

Hemodynamic Management

• Maintain systolic blood pressure >110 mmHg in patients with suspected spinal cord injury to reduce mortality 1
• Ensure adequate volume resuscitation while avoiding over-resuscitation 2

Imaging Protocol for Stable Patients

• CT angiography (CTA) is the first-line imaging modality with 90-100% sensitivity and 98.6-100% specificity for vascular injuries 1
• CTA simultaneously evaluates extravascular soft tissue and aerodigestive injuries with high sensitivity (100%) and specificity (93.5-97.5%) 1
• Initial radiographs may be useful to identify radio-opaque foreign bodies, soft-tissue swelling, airway compromise, fractures, and subcutaneous emphysema before proceeding to CTA 1
• CT esophagography may be performed in conjunction with CTA for suspected digestive tract injuries (sensitivity 95-100%) 1

Additional Imaging Considerations

• Catheter angiography is reserved for:
  • Equivocal CTA findings with concerning penetrating foreign body trajectory
  • Cases where endovascular therapy is planned 1
• MRI is valuable for evaluating spinal cord injury, traumatic disk injury, and ligamentous injury in stable patients without metallic foreign bodies 1, 3
• Ultrasound has limited utility in neck trauma due to overlying soft tissue injury and limited evaluation of deep structures 1

Management Algorithm

1. Unstable patient with hard signs:

   • Immediate surgical exploration without delay for imaging 1, 2

2. Stable patient:

   • Proceed with CTA regardless of injury zone 1
   • Based on CTA findings:
     • Negative: Observation with serial examinations 1, 2
     • Positive: Targeted management based on specific injuries identified 1

Common Pitfalls to Avoid

• Delaying surgical exploration in patients with hard signs of vascular or aerodigestive injury 1, 2
• Failing to maintain cervical spine immobilization during initial assessment and management 1
• Overlooking subtle signs of aerodigestive tract injuries, which may present with minimal symptoms initially 4
• Relying solely on physical examination without appropriate imaging in stable patients 1
• Neglecting to consider potential end-organ injury, particularly to the brain, when cervical vascular injury is present 1
