摘要

目的初步评价无创脑电阻抗（cerebral electrical impedance

CEI）测定在蛛网膜下腔出血（subarachnoid hemorrhage

SAH）患者脑水肿监测中的应用价值。方法对发病后3 d内的46例SAH患者，采用50 kHz及0.1 mA的刺激电流进行连续CEI测定。以扰动系数（perturbative index，PI）表示CEI测定结果，PI值大于9.5，或连续3次或3次以上病灶侧与对侧的PI之差大于0.3定义为CEI异常。结果 21.7%（10/46）患者首次测定时发现双侧CEI明显升高，PI9.5，其中7例头部CT显示全脑水肿，另3例头部CT未显示脑水肿；其余36例首次测定时CEI在正常范围，头部CT均未显示脑水肿。间隔3 d后，CEI检测发现有5例患者PI值升高明显，复查CT显示脑水肿。结论 CEI检测可较敏感地反映SAH患者脑水肿的存在，有助于及时判断病情和指导治疗。

Abstract

Objective To evaluate the application of noninvasive cerebral electrical impedance (CEI) measurement in monitoring brain edema after subarachnoid hemorrhage (SAH). Methods CEI was measured in 46 SAH patients stimulated with an invariable secure current at a frequency of 50 kHz and an intensity of 0.1 mA within 3 d after onset of the disease. CEI was expressed as the perturbative index (PI). CEI was defined as abnormal when PI was over 9.5 or the difference in PI was over 0.3 for 3 or more 3 measurements of PI in foci and bilateral side. Results The CEI was significantly increased in 10 patients (21.7%) with their PI 9.5. Among the 10 patients

CT showed global cerebral edema in 7 and no cerebral edema in 3. The CEI was within the normal range in the remaining 36 patients with no obvious cerebral edema. The PI was significantly increased in 5 SAH patients with obvious cerebral edema in 3 d after onset of the disease. Conclusion CEI measurement can sensitively show cerebral edema in SAH patients

and judge the condition of patients and adjust their treatment.
