Clinical application of transcranial Doppler ultrasonography in PICU / 中国小儿急救医学

ABSTRACT

Transcranial Doppler ultrasonography(TCD)can be usd to monitor the cerebral blood flow changes noninvasively in real time. It provides important information for cerebrovascular hemodynamics in children with nervous system diseases,especially for the critically ill children.TCD is widely used in diagnosis and therapy of traumatic brain injury,increased intracranial pressure,cerebral vasospasm,stroke,cerebral vascular dysfunction,central nervous system infection,brain death.TCD can reveal the cerebral perfusion and the response to the treatment and help to guide the treatment.Besides,through the analysis of the change of the cerebrovascular hemodynamics,we can find the underlying pathophysiology mechanism of the diseases. In this paper,the application of TCD was reviewed to spread the use of TCD in monitoring and treantment of children in PICU.
