Critical Cases - Stab Wound to the Neck!

HPI: 41yo male self-inflicted stab wounds to neck and chest

 

 

PE: VS are unremarkable

GENERAL: speaking in 2 word sentences, GCS 15

NECK: Two laceration to the left anterior neck, with slow oozing and bubbling from the medial laceration, +palpable crepitus throughout the neck 

CHEST: crepitus over neck and upper chest, with small superficial laceration to the right upper chest

 

DDx:

  • Concern for injury to trachea +/- esophagus, vascular, or neuro structures
  • PTX vs hydrothorax vs pneumomediastinum

Initial management:

  • ABCs!!
  • Airway: anticipate difficult airway; use VL or fiberoptic/ flexible intubating bronchoscope for intubation and anticipate possible cricothyrotomy
  • Breathing: up to 20% have hemo- or pneumothorax
  • Circulation: hold pressure on bleeding wounds (but not both carotids simultaneously) In patients with penetrating neck trauma

Diagnostics:

  • Physical exam is >95% sensitive for detecting clinically significant vascular and aerodigestive injuries
  • CXR: note subcutaneous emphysema, +pneumomediastinum, +ETT in place, note two washers marking neck wounds

 

 

Management:

  • Assess airway and look for signs for aerodigestive injury
  • OR for neck exploration if: shock, expanding hematoma, active bleeding, subcutaneous emphysema, dysphagia, hoarseness, stridor, or obvious tracheal or esophageal injuries
  • "Hard signs" of need for OR: include air bubbling from the wound, expanding hematoma, hematemesis, shock, diminished radial pulse, +/- neuro deficits
  • This patient was intubated using VL and there was blood seen just below cords prior to passing ETT
  • Patient was taken level 0 to the OR for neck exploration 

 

Take home points:

  • Zone I → CTA chest
  • Zone II → Violation of platysma → send to OR; if not, OBSERVE. Wounds that do not penetrate the platysma are not life threatening
  • Zone III → CT neck with contrast +/- angiography. Leave impaled objects as they may be providing tamponade
  • DON’T FORGET YOUR ABCs!
