Progression of intracranial pressure in patients with traumatic brain injury based on TCD cerebral blood flow spectrum

Transcranial doppler (TCD) can dynamically and non-invasively monitor and evaluate cerebral hemodynamic changes, and intracranial pressure (ICP) is an important indicator for assessing the intracranial condition of patients with traumatic brain injury. In clinical work, an accurate and convenient non-invasive ICP monitoring method has been being explored. Because TCD has the advantages of non-invasive, low-cost and quick at the bedside, and the detection of cerebral blood flow spectrum by TCD can also indirectly evaluate ICP changes. This is great significance for clinical guidance of treatment. Now this article combines domestic and foreign research, and combines ICP monitoring technology and TCD technology, the formula and method of establishing ICP evaluation model based on pulsatility index in the previous literature are integrated, and the research progress of TCD cerebral blood flow spectrum evaluation ICP is reviewed.
