Malaysian Clinical Practice Guidelines for Early Management of Head Injury in Adults

I must note that the evidence provided does not contain the actual Malaysian Clinical Practice Guidelines for early management of head injury in adults. The studies provided are primarily international consensus guidelines (WSES, French Society of Anaesthesia) and North American clinical policies (ACEP). However, I can provide a comprehensive framework based on the highest-quality international guidelines that would typically inform Malaysian practice.

Initial Assessment and Triage

All head injury patients require immediate assessment using the Glasgow Coma Scale (GCS) and systematic evaluation for life-threatening injuries 1.

Severity Classification

  • Mild TBI: GCS 13-15 2, 3
  • Moderate TBI: GCS 9-12 1
  • Severe TBI: GCS ≤8 1

Important caveat: A GCS of 13-15 does not preclude serious intracranial injury—up to 15% of mild TBI patients have acute intracranial injury on CT, and 13.1% may show progression on repeat imaging 4.

Prehospital Management

Severe TBI patients must be managed by a prehospital medicalized team and transferred immediately to a specialized center with neurosurgical facilities 1.

Critical Prehospital Interventions

  • Maintain systolic blood pressure >110 mmHg (even a single episode of SBP <90 mmHg worsens outcome) 1
  • Control ventilation through tracheal intubation with end-tidal CO₂ monitoring, maintaining EtCO₂ between 30-35 mmHg 1
  • Maintain PaO₂ between 60-100 mmHg to prevent hypoxemia 1
  • Maintain PaCO₂ between 35-40 mmHg (avoid hypocapnia which causes cerebral vasoconstriction and ischemia) 1

Polytrauma Management Algorithm

For patients with both head injury and systemic trauma, follow this prioritized approach 1:

  1. Life-threatening hemorrhage requires immediate intervention (surgery/interventional radiology) for bleeding control (100% consensus) 1

  2. After hemorrhage control, perform urgent neurological evaluation (pupils + GCS motor score + brain CT) to determine severity of brain damage (100% consensus) 1

  3. Salvageable patients with life-threatening brain lesions require urgent neurosurgical consultation after hemorrhage control (100% consensus) 1

  4. Maintain SBP >100 mmHg or MAP >80 mmHg during interventions for life-threatening hemorrhage or emergency neurosurgery 1

Imaging Strategies

Indications for Immediate Non-Contrast Head CT

A non-contrast head CT is mandatory in head trauma patients with loss of consciousness or post-traumatic amnesia if ANY of the following is present 1, 2, 3:

  • Headache (especially severe) 1, 2, 3
  • Vomiting (≥2 episodes is high-risk) 1, 2, 5, 3
  • Age >60 years 1, 2, 3
  • Drug or alcohol intoxication 1, 3
  • Deficits in short-term memory 1, 3
  • Physical evidence of trauma above the clavicle 1, 3
  • Post-traumatic seizure 1, 3
  • GCS score <15 1, 2, 3
  • Focal neurologic deficit 1, 3
  • Coagulopathy or anticoagulation therapy 1, 2, 3

For patients WITHOUT loss of consciousness or amnesia, CT should be considered if there is 1:

  • Focal neurologic deficit
  • Vomiting
  • Severe headache
  • Age ≥65 years
  • Physical signs of basilar skull fracture
  • GCS <15
  • Coagulopathy
  • Dangerous mechanism of injury (ejection from vehicle, pedestrian struck, fall >3 feet/5 stairs)

CT Protocol

Perform brain and cervical CT scan without delay in severe TBI patients 1. The CT should include inframillimetric sections reconstructed with thickness >1mm, visualized with double fenestration (CNS and bones) 1.

Consider early CT-angiography of supra-aortic and intracranial arteries in patients with risk factors 1:

  • Cervical spine fracture
  • Focal neurological deficit unexplained by brain imaging
  • Claude Bernard-Horner syndrome
  • LeFort II or III facial fractures
  • Basilar skull fractures
  • Soft tissue neck lesions

Neurosurgical Intervention

Patients at risk for intracranial hypertension (comatose with radiological signs of IH) require ICP monitoring regardless of need for emergency extra-cranial surgery (97.5% consensus) 1.

In cases of cerebral herniation, use osmotherapy and/or temporary hypocapnia while awaiting or during emergency neurosurgery 1.

Transfusion and Coagulation Management

Maintain hemoglobin >7 g/dL during interventions (higher threshold for elderly or patients with cardiovascular disease) 1.

Maintain platelet count >50,000/mm³ for life-threatening hemorrhage intervention; higher values advisable for emergency neurosurgery including ICP probe insertion (100% consensus) 1.

Discharge Criteria and Follow-Up

Patients with mild TBI and negative head CT are at minimal risk for delayed intracranial lesions and may be safely discharged 2.

Mandatory Discharge Requirements

  • Provide both written and verbal instructions at 6th-7th grade reading level 2
  • Instruct immediate return for: memory problems, confusion, abnormal behavior, increased sleepiness, loss of consciousness, worsening headache, vision problems, or seizures 2, 5
  • Educate about postconcussive symptoms: dizziness, balance problems, nausea, vision problems, sensitivity to noise/light, depression, mood swings, anxiety, irritability, sleep disturbances 2, 5

Exceptions Requiring Individualized Assessment

The following populations may require admission despite negative CT 2:

  • Bleeding disorders
  • Anticoagulation therapy
  • Antiplatelet therapy
  • Previous neurosurgical procedures

Critical pitfall: Anticoagulated patients (including warfarin) require emergent head CT regardless of normal GCS or absence of visible injury, as normal neurologic exam does not exclude intracranial injury in this population 2.
