A 31-year-old male is transported to the trauma center via ambulance following an assault … — USMLE Step 3

A 31-year-old male is transported to the trauma center via ambulance following an assault with a sharp object. He sustained a single stab wound to the left anterolateral neck, horizontally aligned with the cricoid cartilage. He appears severely distressed, diaphoretic, and is clutching his neck. His temperature is $36.6^\circ\text{C}$ ( $97.9^\circ\text{F}$ ), pulse is $142\text{/min}$ , blood pressure is $78/42\text{ mm Hg}$ , and respirations are $32\text{/min}$ . Oxygen saturation is $90\%$ on ambient air. Physical examination demonstrates a $4\text{-cm}$ laceration with pulsatile hemorrhage that is only partially controlled with direct pressure by the emergency responders. A prominent, tense hematoma is visibly enlarging and deviating the larynx to the contralateral side, accompanied by biphasic stridor. Which of the following interventions are mandatory immediate next steps in this patient's procedural management? (Select all that apply.)

Endotracheal intubation to secure the airwayCevap
Exploratory cervicotomy in the operating suiteCevap
C
Computed tomography angiography of the cervical vessels
D
Direct transfer to the intensive care unit for continuous hemodynamic monitoring
E
Urgent flexible esophagoscopy to evaluate for aerodigestive tract injury

Cevap

The mandatory immediate next steps are securing the airway with endotracheal intubation and performing an exploratory cervicotomy in the operating suite.

The correct interventions directly address the life-threatening conditions in a patient presenting with penetrating neck trauma and 'hard signs' of vascular or aerodigestive injury. Hard signs include hemodynamic instability (shock), a rapidly expanding or pulsatile hematoma, active severe hemorrhage, massive subcutaneous emphysema, or airway compromise (such as stridor). The presence of any hard sign mandates immediate surgical exploration (cervicotomy) in the operating suite to achieve hemostasis. Additionally, because the expanding hematoma is deviating the trachea and causing symptomatic compression (stridor), securing the airway via endotracheal intubation is a critical concurrent procedural priority before complete anatomical airway obstruction occurs.

Adım Adım Çözüm

Identify clinical markers of severity in penetrating neck trauma.

The patient exhibits 'hard signs' including hemodynamic instability (shock), an expanding pulsatile hematoma, and airway compromise (stridor).

Hard signs dictate the divergence between medical/diagnostic management and immediate surgical intervention.

Determine the optimal sequencing of interventions.

Diagnostic imaging and monitoring must be bypassed in favor of definitive procedural management.

Delays in achieving hemostasis and airway control in patients with hard signs lead to high mortality.

Select the appropriate procedural interventions.

Endotracheal intubation and exploratory cervicotomy are chosen.

Intubation prevents imminent loss of the airway from external compression, while cervicotomy provides definitive control of the bleeding source.

Anahtar Kavram

Management of penetrating neck trauma with hard signs requires immediate airway stabilization and emergent surgical exploration, bypassing diagnostic imaging.
