a Transcranial Doppler Study of Locally Using Dexamethasone after Brain Injury in Rabbits

Since the introduction of transcranial Doppler (TCD) by Aaslid[1], the measurement of the blood flow velocity (BFV) in basal cerebral arteries has been possible, which offers the advantage of being an easily portable and noninvasive method of assessing intracranial hemodynamics. Yet, TCD in the observation of post－traumatic treatment has not been universally applied. It was once thought that a large dose of steroid had an obvious therapeutic effect on brain trauma and cerebral edema. As t…
