交感肾上腺系统不能维持直立位的脑灌注压。
The sympathoadrenal system is unable to maintain cerebral perfusion pressure in the upright posture.
早期维持有效脑血流量及脑灌注压对改善脑出血的预后有重要的意义。
Maintaining the effective volume of cerebral blood flow and cerebral perfusion pressure on the early stage will have a great significance on improving the prognosis of cerebral hemorrhage.
结果患儿的预后与脑受压程度、ct值、颅内压和脑灌注压密切相关。
Results Poor prognosis was associated with severe brain compression, decreased CT value over the edematous brain, increased intra cranial pressure and reduced cerebral perfusion.
当交感肾上腺系统不能维持直立位的脑灌注压时，就会发生直立不耐受。
Orthostatic intolerance results when the sympathoadrenal system is unable to maintain cerebral perfusion pressure in the upright posture.
目的 ：应用新西兰兔急性局限性颅高压模型 ，研究经颅多谱勒频谱参数与脑灌注压的关系。
