Management of Brain Bleeding from Head Trauma
Immediate non-contrast head CT is mandatory for all patients with suspected traumatic brain injury, followed by urgent neurosurgical consultation if intracranial hemorrhage is confirmed, while simultaneously maintaining mean arterial pressure ≥80 mmHg and correcting any coagulopathy. 1
Immediate Diagnostic Workup
Imaging Priority
- Obtain urgent non-contrast head CT scan immediately without delaying for laboratory results if the patient is stable enough for transport 1
- Non-contrast head CT is the definitive first-line imaging study and should not be delayed 1
- For hemodynamically stable patients with high-energy injuries, proceed directly to CT assessment 1
Essential Laboratory Studies
- Order coagulation panel (PT/INR, aPTT) to evaluate for coagulopathy 1
- Obtain complete blood count with hemoglobin and platelet count 1
- Measure serum lactate to estimate extent of bleeding and shock 1
- Measure base deficit as an alternative marker for bleeding and tissue hypoperfusion 1
- Type and crossmatch blood products in preparation for potential transfusion 1
Neurological Assessment
- Perform urgent neurological evaluation including pupillary assessment and Glasgow Coma Scale (GCS) motor score 1
- Document mechanism of injury as this identifies patients at risk for significant hemorrhage 1
Hemodynamic Management
Blood Pressure Targets
- Maintain mean arterial pressure ≥80 mmHg in patients with severe traumatic brain injury (GCS <8) 2, 3
- Maintain systolic blood pressure >100 mmHg during initial interventions 1, 3
- For patients with combined hemorrhagic shock and severe TBI, prioritize cerebral perfusion with MAP ≥80 mmHg 1
Fluid Resuscitation Strategy
- Use 0.9% normal saline as the crystalloid of choice for fluid resuscitation in brain injury 3
- Avoid hypotonic solutions such as Ringer's lactate in patients with severe head trauma as they can worsen cerebral edema 2
- Restrict colloid use due to adverse effects on hemostasis 2
- For isolated TBI without hemorrhagic shock, avoid restricted volume strategies that may compromise cerebral perfusion 2
Vasopressor Support
- Administer noradrenaline in addition to fluids if target arterial pressure cannot be maintained 2
- Infuse dobutamine if myocardial dysfunction is present 2
Coagulation Management
Platelet Transfusion
- Maintain platelet count above 50×10⁹/L in patients with ongoing bleeding and/or traumatic brain injury 3
- This threshold is critical for patients with TBI regardless of active bleeding status 3
Red Blood Cell Transfusion
- Transfuse red blood cells when hemoglobin level is <7 g/dL 3
- Consider higher transfusion threshold for elderly patients or those with limited cardiovascular reserve 3
- Target hemoglobin of 70-90 g/L if erythrocyte transfusion is necessary 2
Coagulopathy Reversal
- Perform early, repeated hemostasis monitoring including PT/INR, fibrinogen, and platelet counts 2
- Verify absence of coagulopathy before considering any elective interventions 4
Neurosurgical Considerations
Immediate Consultation
- Obtain urgent neurosurgical consultation immediately after CT confirms intracranial hemorrhage 1
- Do not delay consultation for additional workup 1
- All salvageable patients with life-threatening brain lesions require immediate neurosurgical evaluation 1
Intracranial Pressure Management
- Mannitol 0.25 to 2 g/kg body weight as 15-25% solution over 30-60 minutes for reduction of intracranial pressure 5
- For pediatric patients: 1-2 g/kg body weight or 30-60 g/m² body surface area over 30-60 minutes 5
- Use filter in administration set when infusing 25% mannitol 5
- Monitor renal function closely as mannitol can cause acute kidney injury 5
Critical Pitfalls to Avoid
Respiratory Management
- Avoid routine hyperventilation as it worsens outcomes in TBI patients 1
- Only use hyperventilation if there are signs of imminent cerebral herniation 1
Secondary Brain Injury Prevention
- Avoid hypotension and hypoxia, which worsen secondary brain injury 1
- Do not use hypotonic fluids in severe head trauma 2
Monitoring Complications
- Mannitol may increase cerebral blood flow and risk of postoperative bleeding in neurosurgical patients 5
- Mannitol may worsen intracranial hypertension in children with generalized cerebral hyperemia during first 24-48 hours post-injury 5
- Monitor electrolytes (sodium, potassium) carefully during mannitol administration 5
Thromboprophylaxis Timing
- Apply early mechanical thromboprophylaxis with intermittent pneumatic compression while patient is immobile and has bleeding risk 2
- Delay pharmacological thromboprophylaxis until at least 24 hours after bleeding has been controlled 2, 4
- Combine pharmacological and mechanical prophylaxis within 24 hours after bleeding control until patient is mobile 2
- Do not use graduated compression stockings 2
Special Populations
Anticoagulated Patients
- Patients on anticoagulants have increased risk of initial hemorrhage and mortality 6
- Larger bleeds are associated with substantially higher mortality risk 7
- The risk of delayed intracranial hemorrhage in anticoagulated patients with normal initial CT is approximately 0.6% 8
