适当的过度换气可降低未受损脑区血流减少导致的高颅内压(ICP),改善脑损伤区的血流。经颅多普勒(TCD)能迅速测定脑血管对CO_2变化的反应,本文通过测定CO_2变化对严重颅内出血患者脑血流速度的作用,评定了脑血管CO_2反应性、ICP 与临床结局的相关性。选择40名患者进行研究,男25名,女15名。其中创伤性蛛网膜下腔出血12名,脑出血15名,自发
Proper hyperventilation reduces high intracranial pressure (ICP) due to reduced blood flow in intact brain regions and improves blood flow in areas of brain damage. Transcranial Doppler (TCD) can rapidly determine the response of cerebrovascular to changes in CO 2. In this paper, the effects of CO 2 changes on cerebral blood flow velocity in patients with severe intracranial hemorrhage were measured to evaluate the correlation between cerebrovascular CO 2 reactivity and ICP and clinical outcome Sex. 40 patients were selected for study, 25 males and 15 females. Traumatic subarachnoid hemorrhage in which 12, 15 cerebral hemorrhage, spontaneous
