Fifteen Hundred Reasons to Open the Chest - Trauma Surgery clinical simulation case. A 28-year-old male presenting 8 minutes after sustaining a single...
Age: 28 • Gender: Male • Setting: Emergency Triage
Clinical Presentation & History
A 28-year-old male presenting 8 minutes after sustaining a single left-sided anterior chest stab wound during an altercation. He is agitated, tachypneic, and hypotensive with decreased left-sided breath sounds and a rapid, gushing hemorrhage from a 32Fr thoracostomy tube placed in the trauma bay.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Phase 1 — Initial Trauma Bay Assessment & Tube Thoracostomy
The 1,500 mL rule for emergent thoracotomy after penetrating chest trauma is one of the highest-yield trauma surgery numbers. Some sources use >200 mL/hour ongoing as the alternate criterion.
Massive transfusion in trauma is balanced 1:1:1 (PRBC:FFP:platelets) — component-dominant resuscitation is associated with higher death from exsanguination in PROPPR.
Calcium is the silent killer of massive transfusion — every unit of citrated blood product chelates ionized calcium; replace empirically with 1–2 g Ca-gluconate per 4 units of blood.
TXA within 3 hours of injury reduces death from bleeding (CRASH-2); benefit is lost or reversed beyond 3 hours or with inappropriate use.
Damage-control surgery: control bleeding and contamination first, restore physiology in ICU, then return for definitive repair 24–48 hours later.
EDT (emergency department thoracotomy) has the highest survival of any indication in penetrating thoracic injury (~10–35%), but is futile in blunt trauma without signs of life.
Autotransfused shed blood has no functional fibrinogen or platelets — must be supplemented with FFP and platelets.
