摘要:
[摘要] 重型颅脑损伤(severe traumatic brain injury,sTBI)是世界范围内致死率、致残率极高的疾病,经颅多普勒(transcranial Doppler,TCD)可以高效安全地在床边监测sTBI患者的病理生理学变化,其检测结果可重复性高。TCD可以无创、实时获取脑组织二维形态,通过计算颅内血管的血流状态,获得脑血流动力学信息,通过分析脑血流速度及方向、血管自身调节功能、血管阻力变化来评估颅内压。该文就床边TCD在颅脑创伤救治的临床应用现状及展望进行综述。

Abstract:
[Abstract] Severe traumatic brain injury(sTBI) is a disease with extremely high mortality and disability rate worldwide. Transcranial Doppler(TCD) ultrasound can efficiently and safely monitor the pathophysiological changes of sTBI patients at the bedside, and its detection results are highly reproducible.TCD can obtain the two-dimensional morphology of brain tissues in a non-invasive and real-time manner. The cerebral hemodynamic information is obtained by calculating the blood flow state of intracranial vessels, and the intracranial pressure is evaluated by analyzing the velocity and direction of cerebral blood flow, the function of vascular self-regulation and the change of vascular resistance. This paper reviews the clinical application status and prospect of bedside TCD in the treatment of craniocerebral trauma.
