Study Notes
Hemorrhage Classifications in Trauma
- Common Cause of Shock: Hypovolemia secondary to hemorrhage is the leading cause of shock in trauma patients.
Hemorrhage Classifications
-
Class I Hemorrhage:
- Blood loss: Approximately 500 mL or 15% of total blood volume
- Heart Rate (HR): Up to 100 bpm
- Blood Pressure (BP): Typically normal
- Urine Output (UOP): Decreased (20-30 mL/hour)
- Symptoms: Mild anxiety
-
Class II Hemorrhage:
- Blood loss: 1000-1500 mL or 20-30% of total blood volume
- Pulse pressure: Decreased
- Capillary refill delay: More than 2 seconds
-
Class III Hemorrhage:
- Blood loss: 1500-2000 mL or 30-40% of total blood volume
- HR: Greater than 120 bpm
- BP: Decreased
- Respiratory Rate (RR): 30-40 breaths per minute
- UOP: Decreased (5-15 mL/hour)
- Symptoms: Very anxious, confused, capillary refill delay greater than 2 seconds
- Treatment: Crystalloid solutions and/or blood products
-
Class IV Hemorrhage:
- Blood loss: More than 2000 mL or more than 40% of total blood volume
- HR: Exceeding 140 bpm
- RR: Greater than 35 breaths per minute
- Pulse pressure: May be immeasurable
- UOP: Negligible
- Symptoms: Confused, lethargic, prolonged capillary refill
- Treatment: Crystalloid solutions or blood products
Key Intervention
- Treatment for Hypovolemic Shock: Priority is to stop the bleeding followed by the administration of Lactated Ringer’s solution to restore fluid balance.
