Difficulty: MediumInitial Stabilization and Triage

A 24-year-old man is brought to the emergency department by paramedics after sustaining a stab wound to the right upper chest during an altercation. On arrival, he is stuporous, diaphoretic, and in severe respiratory distress. His temperature is 36.5°C (97.7°F), blood pressure is 74/40 mmHg, pulse is 142/min, respirations are 36/min, and pulse oximetry shows 84% on a non-rebreather mask. Physical examination reveals a 3-cm laceration in the right second intercostal space at the midclavicular line. The trachea is visibly deviated to the left, and the jugular veins are prominently distended. Auscultation demonstrates completely absent breath sounds over the right hemithorax with hyperresonance to percussion. Which of the following simultaneous initial stabilization steps are indicated immediately? (Select two)

  1. Perform a right-sided needle or finger thoracostomyAnswer
  2. Establish two large-bore peripheral intravenous linesAnswer
  3. C
    Perform rapid sequence endotracheal intubation
  4. D
    Obtain a stat portable chest radiograph
  5. E
    Perform a focused assessment with sonography for trauma (FAST)

Answer

The most appropriate simultaneous initial steps are to perform a right-sided needle or finger thoracostomy and to establish two large-bore peripheral intravenous lines.
This patient presents with classic signs of a tension pneumothorax following penetrating chest trauma, including profound hypotension, severe respiratory distress, unilateral absence of breath sounds, contralateral tracheal deviation, and jugular venous distention. The accumulating air creates severely elevated intrathoracic pressure that compresses the superior and inferior vena cava, drastically reducing venous return and leading to obstructive shock. The correct initial management requires simultaneous, life-saving interventions: immediate mechanical decompression of the pleural space (via needle or finger thoracostomy) to restore venous return and cardiac output, alongside the establishment of large-bore intravenous access to facilitate the volume and blood product resuscitation appropriate for a hemodynamically unstable major trauma patient.

Step-by-Step Solution

1
Identify the primary pathophysiologic derangement from the clinical signs.
The patient has obstructive shock secondary to a right-sided tension pneumothorax, evidenced by severe hypotension, absent right breath sounds, tracheal deviation, and distended neck veins.
Recognizing the clinical triad of tension pneumothorax is essential because it dictates emergent, empiric intervention without waiting for diagnostic confirmation.
2
Determine the necessary simultaneous interventions for stabilization.
Immediate pleural decompression and concurrent securement of vascular access.
Pleural decompression relieves the obstructive intrathoracic pressure to restore cardiac output, while large-bore intravenous access ensures readiness for volume and blood resuscitation required in penetrating trauma.
