Management of Head Trauma Patients with Normal Vital Signs

Initial Assessment

The World Journal of Emergency Surgery recommends performing an urgent neurological evaluation, including pupil assessment and Glasgow Coma Scale motor score, to determine the severity of brain damage in head trauma patients with normal vital signs 1
Obtain brain and cervical CT scan without delay to identify potential intracranial injuries in head trauma patients with normal vital signs 2
Consider using transcranial Doppler as part of the initial assessment to evaluate brain hemodynamics and estimate cerebral perfusion in head trauma patients with normal vital signs 3
Assess for signs requiring immediate tracheal intubation, including GCS ≤ 8, significantly deteriorating conscious level, loss of protective laryngeal reflexes, bilateral fractured mandible, and copious bleeding into the mouth in head trauma patients with normal vital signs 4, 5

Urgent neurosurgical consultation and intervention is required for head trauma patients with life-threatening brain lesions, and position the patient with 20-30° head-up tilt to reduce intracranial pressure (ICP) 1, 6
Maintain systolic blood pressure > 100 mmHg or mean arterial pressure > 80 mmHg in head trauma patients with life-threatening brain lesions 1
Consider ICP monitoring in patients in coma with radiological signs of intracranial hypertension, and maintain PaO₂ ≥ 13 kPa and PaCO₂ between 4.5-5.0 kPa 1, 6

Transfer patients to a specialized center with neurosurgical facilities as soon as possible, ensuring proper positioning during transfer with 20-30° head-up tilt while maintaining spinal immobilization if indicated 2, 7
Maintain continuous monitoring of vital signs and neurological status during transfer, and prepare appropriate medications including sedatives, analgesics, anticonvulsants, and vasoactive drugs 4, 6, 7

Do not delay neurological evaluation and brain CT scan in head trauma patients, even with normal vital signs, as deterioration can occur rapidly 1
Avoid transporting patients with unstable vital signs; stabilize first before transfer 5
Remember that normal vital signs do not exclude serious intracranial pathology; vigilant monitoring is still required 3
Avoid excessive fluid administration which may worsen cerebral edema; use isotonic solutions (0.9% saline) when fluids are needed 6

For patients requiring emergency neurosurgery, maintain platelet count > 50,000/mm³ (higher values are advisable) 1
Maintain blood glucose levels between 6-10 mmol/L in head trauma patients with normal vital signs 5
Despite normal vital signs, consider the possibility of occult hemorrhage elsewhere that may later manifest as hemodynamic instability 8
Early transfer to a specialized neurosurgical center improves outcomes in patients with severe traumatic brain injury 2
