Golden Hour in Trauma

1. Definition of Golden Hour

• The Golden Hour refers to the first 60 minutes following a traumatic injury, during which rapid assessment, resuscitation, and definitive care can significantly impact survival.

• Coined by Dr. R. Adams Cowley (Father of Trauma Medicine).

• A delay in treatment beyond this period leads to higher mortality and complications.

2. Physiological Basis of the Golden Hour

During trauma, rapid deterioration occurs due to:

(A) Hemorrhagic Shock

• Leading cause of preventable trauma deaths.

• Uncontrolled bleeding → Hypovolemia → Hypoxia → Multi-organ failure.

(B) Traumatic Brain Injury (TBI)

• Secondary brain injury (due to hypotension, hypoxia, or hypercapnia) worsens neurological outcomes.

• GCS < 8 → Early intubation required.

(C) Systemic Inflammatory Response

• Trauma triggers a hyperinflammatory state, increasing the risk of coagulopathy, sepsis, and multi-organ dysfunction syndrome (MODS).

3. Components of Golden Hour Management

(A) Prehospital Care

• Rapid Scene Assessment using ABCDE approach.

• Immediate Airway Control (Intubation if GCS < 8).

• Control Hemorrhage (Tourniquet, direct pressure, TXA if needed).

• IV/IO Access & Fluid Resuscitation (Permissive hypotension in uncontrolled bleeding).

• Early Notification to Trauma Center (Trauma Team Activation).

(B) Emergency Department Resuscitation

• Primary Survey (ABCDE):

• A: Secure airway, intubate if needed.

• B: Oxygenation, ventilate if required.

• C: Stop bleeding, blood transfusion (Massive Transfusion Protocol if required).

• D: Neurological assessment (GCS).

• E: Exposure and prevent hypothermia.

• Secondary Survey:

• Head-to-toe examination.

• Imaging (FAST, X-ray, CT if stable).

(C) Definitive Care

• Emergency Surgery if needed (Laparotomy, Damage Control Surgery).

• ICU Management for critically ill trauma patients.
