Transcranial Doppler on Admission of Patients With Mild to Moderate Traumatic Brain Injury (TCD)

April 25, 2014 updated by: University Hospital, Grenoble

Prospective, Multicentre, Observational Study

Patients with mild to moderate traumatic brain injury (TBI) are at risk for secondary neurological deterioration. Their outcome within the first week after injury could be predicted by clinical signs, brain CT scan and transcranial doppler (TCD) on admission to the emergency room. The investigators aim to evaluate the diagnostic performance of TCD to screen patients presented with mild to moderate TBI and mild lesions on CT scan, i.e., Trauma Coma Data Bank, TCDB classification II. The principal outcome measure is the negative predictive value of TCD.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Negative predictive value of transcranial doppler
Time Frame: within the first week after the injury

Patient with mild to moderate traumatic brain injury (Glasgow Coma Scale 9-15) and a CT scan (TCDB II).TCD is performed within 8 hours after the trauma.

Aggravation defined by:

  • a decrease in the Glasgow Coma Scale of 2 points or more from the initial value, in the absence of pharmacological sedation.
  • a neurological deterioration sufficient to warrant intervention: mechanical ventilation, sedation, osmotherapy, barbiturates, transfer to more intensive care, or neurosurgical intervention.
within the first week after the injury

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: within the first week after trauma

Number of brain CTscan performed within 7 days after the trauma.

Number of devices inserted to monitor intracranial pressure.

Secondary admissions to intensive care unit.
