Clinical Trial 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.


Clinical Trial Description

The transcranial dopplers will be carry out on 75 brain-damaged patients by 13 emergency residents physicians after a theoretical and practical training. They will be evaluated by 8 experts. The primary endpoint will be the mean number of transcranial dopplers required to have an excellent concordance between resident and expert. The concordance between the Doppler findings of the resident and the expert would exceed 0.8 before 30 examinations. The learning curve assessed on the duration necessary to acquire good quality data should decrease rapidly with the repetition of the examinations. Validating the transcranial Doppler learning curve for junior emergency physician would allow them to perform this exam safely and efficiently. Transcranial Doppler may be easy and fast to learn but the persistence of its competency over time should be evaluated. ;
