基于TCD脑血流频谱评估颅脑损伤患者颅内压的研究进展

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

经颅多普勒(TCD)可以动态无创地监测和评估脑血管血流动力学变化,而颅内压(ICP)是评估颅脑损伤患者颅内病情的重要指标。临床工作中一直在探索一种准确、方便的无创ICP监测方法,由于TCD具有床旁无创、低廉快捷的优势,并且通过TCD检测脑血流频谱还可间接评估ICP变化,对临床治疗有重要的指导意义。本文综合国内外研究,结合ICP监测技术和TCD技术,并整合既往文献中基于搏动指数建立ICP评估模型的公式方法,就TCD脑血流频谱评估ICP的研究进展作一综述。

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.
