Brief Summary

Transcranial Doppler is a noninvasive tool. Using velocity measurements and pulsatility index it allows the evaluation of cerebral haemodynamics. In patients presenting brain injury cerebral perfusion may be impaired. Indirect cerebral blood flow can be monitored and risk of neurological worsening can be detected using transcranial Doppler. Education and performance of emergency physicians must be evaluated on brain-injured patients because this tool is operator dependent. The main objective of this study is to estimate the average number of exams required to learn transcranial Doppler within junior emergency physicians with the achievement of their learning curve. We will perform a prospective, monocentric, observational study within the neurosurgical resuscitation department of Grenoble Alpes University Hospital.
