Damage Control Resuscitation Principles
Damage control resuscitation (DCR) is a systematic approach combining permissive hypotension, early balanced blood product administration, rapid hemorrhage control, and prevention of the lethal triad (hypothermia, acidosis, coagulopathy) to maximize survival in severely hemorrhagic trauma patients 1, 2.
Core Resuscitation Strategy
Hemodynamic Targets
- Maintain systolic BP 80-90 mmHg (MAP 50-60 mmHg) until hemorrhage is controlled in patients without traumatic brain injury (TBI) 1
- Escalate to MAP ≥80 mmHg in severe TBI (GCS <8) to maintain cerebral perfusion 1
- Add noradrenaline if restricted volume strategy fails to maintain target pressure 1
- Use dobutamine for myocardial dysfunction 1
This permissive hypotension strategy prevents dilutional coagulopathy and limits ongoing blood loss until definitive hemorrhage control is achieved 2, 3.
Fluid Management
- Initiate with 0.9% NaCl or balanced crystalloid solution 1
- Avoid hypotonic solutions (Ringer's lactate) in severe head trauma 1
- Restrict colloid use due to adverse hemostatic effects 1
- Minimize crystalloid administration overall—the era of massive crystalloid resuscitation is over 3, 4
Hemostatic Resuscitation
Blood Product Administration
Implement early balanced transfusion strategy using either 1:
- FFP:pRBC ratio of at least 1:2 with high platelet:pRBC ratio, OR
- Fibrinogen concentrate or cryoprecipitate plus pRBC
- Target hemoglobin 70-90 g/L 1
- Administer blood products resembling whole blood composition early in resuscitation 4
- Use whole blood when available 5
Antifibrinolytic Therapy
Administer tranexamic acid (TXA) immediately 1:
- Loading dose: 1g IV over 10 minutes (en route to hospital if feasible)
- Maintenance: 1g IV over 8 hours
- Must be given within 3 hours of injury
- Do not await viscoelastic assessment results before administration 1
Coagulation Monitoring
- Use goal-directed strategy guided by viscoelastic monitoring and/or standard laboratory values 1
- Continue resuscitation measures based on these parameters 1
Temperature Management
Implement early measures to reduce heat loss and actively warm hypothermic patients to achieve and maintain normothermia 1. Hypothermia is a critical component of the lethal triad and must be aggressively prevented 3, 6.
Hemorrhage Control
Surgical Approach
Perform damage control surgery in patients with 1:
- Hemorrhagic shock with ongoing bleeding
- Coagulopathy
- Vascular and pancreatic injuries
- Hypothermia, acidosis, and/or combined abdominal inaccessible major anatomic injury
- Need for time-consuming procedures
The surgical strategy involves abbreviated procedures to control hemorrhage and contamination, followed by ICU resuscitation and planned re-operation 4, 7.
Pelvic Trauma
- Apply pelvic binder pre-hospital for suspected pelvic fracture 1
- Perform early pelvic ring closure and stabilization in hemorrhagic shock 1
- Consider temporary extra-peritoneal packing when bleeding is ongoing or angioembolization cannot be achieved timely 1
Adjunctive Measures
- Consider REBOA (resuscitative endovascular balloon occlusion of the aorta) for noncompressible life-threatening hemorrhage 1
- Use topical hemostatic agents with other surgical measures for moderate arterial bleeding or venous/parenchymal injuries 1
- Consider cell salvage for severe bleeding from abdominal, pelvic, or thoracic cavities 1
Additional Critical Elements
- Prevent and correct hypocalcemia 6, 7
- Avoid acidosis through balanced resuscitation and rapid hemorrhage control 6, 7
- Implement team-based protocols for rapid patient delivery to definitive care (OR or interventional radiology) 3
Common Pitfalls
- Delaying TXA administration beyond 3 hours renders it ineffective 1
- Excessive crystalloid administration worsens dilutional coagulopathy 3, 4
- Failing to recognize that DCR is a time-dependent intervention requiring immediate implementation 2, 3
- Not adjusting blood pressure targets for TBI patients, risking secondary brain injury 1
