Massive Hemorrhage – Reassessment Matters
MARCH: Massive Hemorrhage – Reassessment Matters
🔴 Scenario
You arrive first on scene of a vehicle vs pedestrian crash.
A bystander applied a tourniquet to the patient’s left thigh.
EMS is 6–8 minutes out. The patient is conscious, pale, and anxious.
M – Massive Hemorrhage
✅ What To Do
  • Reassess the tourniquet Is it high and tight? Is bleeding fully controlled?
  • If bleeding continues: Tighten the tourniquet until bleeding stops Apply a second tourniquet above the first if needed
  • Check for hidden bleeding Groin, buttocks, armpits, behind knees
  • If a tourniquet can’t be placed: Pack the wound and apply direct pressure
👀 What To Look For
  • Blood soaking through clothing or bandages
  • Pooling blood beneath the patient
  • Pale or clammy skin
  • Fast pulse or increasing anxiety (early shock signs)
🆚 Civilian vs Law Enforcement Response
🧍‍♂️Civilian Focus
  • Prioritize personal safety
  • Call 911 early
  • Use commercial or improvised tourniquets
  • Apply direct pressure if unsure
  • Reassess only if safe to do so
Goal: Stop the bleeding until help arrives
Law Enforcement / First Responder Focus
  • Ensure scene security
  • Apply rapid hemorrhage control
  • Carry and use department-issued TQs and hemostatic gauze
  • Perform systematic MARCH reassessments
  • Prepare for handoff to EMS
Goal: Stabilize, reassess, and maintain control until transport
👨‍🏫 Instructor Note
Tourniquets fail more often from poor placement or hesitation than from overuse.
Pain is expected. Bleeding control always comes first.
Reassess after movement, stress, or time passes.
🔑 Key Takeaway
The first tourniquet isn’t the finish line — reassessment saves lives.
