微透析技术为微侵袭、连续动态监测活体脑细胞外液神经生化物质变化的方法。近年来国内外应用微透析技术对动脉瘤性蛛网膜下腔出血(aSAH)患者进行连续监测,通过对细胞外液中葡萄糖、乳酸、丙酮酸等脑能量代谢指标以及兴奋性氨基酸、甘油等生化物质代谢变化的监测来研究脑血管痉挛、脑缺血以及延迟性缺血性神经功能障碍,同时随着更多有潜在价值的标记物的发现,aSAH的微透析监测范围更加广泛。 Microdialysis technology for micro-invasion, continuous dynamic monitoring of living brain extracellular fluid neurobiochemical changes in the method. In recent years, the application of microdialysis at home and abroad for the continuous monitoring of patients with aneurysmal subarachnoid hemorrhage (aSAH), glucose metabolism through the extracellular fluid, lactate, pyruvate and other brain energy metabolism and excitatory amino acids, glycerol and other biochemical The monitoring of changes in the metabolism of substances to study cerebral vasospasm, cerebral ischemia and delayed ischemic neurological dysfunction, while with more potential value of the discovery of markers, aSAH microdialysis monitoring a wider range.
