应用闪光视觉诱发电位检测颅内压的临床观察

The clinical observation of intracranial pressure measurement by Flash Visual Evoked Potential

目的:应用闪光视觉诱发电位(fVEP)对脑血管病患者进行无创颅内压检测,以了解脑血管疾病急性期颅内压的变化情况,以进一步指导临床治疗。方法:采用fVEP与腰椎穿刺法检测30例脑血管疾病住院患者的颅内压水平,腰穿检测均于fVEP完成后立即进行,并根据检测结果及时给予评估及记录。结果:fVEP无创颅内压测量值与腰椎穿刺测量值比较差异无显著性,存在显著的相关性(t=0.4688,P>0.05,r=0.984,tr=29.479,P<0.001)。结论:fVEP无创颅内压检测仪测量颅内压力可以安全、快速、长期、动态反映颅内压的变化。结果准确可靠。

Objective： To investigate changes of intracranial pressure（ICP） in acute stage of cerebrovascular disease by non-invasive measurement of Flash Visual Evoked Potential（FVEP）. Methods： The ICP of 30 cerebrovascular disease patients were measure by FVEP. Secondly, their cerebral spinalfluid （CSF） pressures were detected through lumbar puncture immediately and compared with ICP. Results： The ICP was no significant difference between FVEP and lumbar puncture（t=0. 4688, P~ 0.05）. A linear relationship between them was observed. （r=0. 984, tr=29. 479, P%0. 001）. Conclusion： FVEP is a safety, rapidly, long-term and dynamic detection method of ICP.
