摘要
探讨急性颅脑损伤后脑血流动力学改变以及脑充血对颅内压的影响。方法：选用急性颅脑损伤颅内血肿术后患者２４例，用经颅多普勒超声仪动态监测脑底动脉及颅外颈内动脉的血流变化，通过颅外减压窗观察颅内压的变化。结果：脑充血组 １２例中 ８例同时行颅外减压术，在脑充血期间 ７例发生颅内压增高，颅内压增高发生率高于无脑充血组（Ｐ＜ ０． ０５）。 ２例因脑充血死亡。结论：脑充血多为双侧性，可引起较广泛的脑水肿及颅内压增高，脑充血严重时可出现颅内压增高危象。
Objective: To evaluate the cerebral hemodynamics and the effect of brain hyperemia in acute head - injured patients with intracranial hematomas (ICH) evacuated. Methods: The velocities of hasal cerebral arteries and extracranial internal carotid arteries were dynamically monitored by transcranial Doppler sonography in 24 acute head - injured patients after their ICH were removed. The intracranial pressure (ICP) were checked through cramal decompressive windows. Results: Two cases died due to brain hyperemia. High ICP occurred in 7 of 8 cases who had been undergone cranial decompression in 12 patients of hyperemic group. The rate of high ICP of hyperemic group was higher than (that) of the nonhyperemic group. Conclusion: Brain hyperemia takes place mostly in bilateral cerebral hemispheres and may result in extensive brain edema and high ICP. High ICP crisis can occur in the acute head -- injured patients with severe brain hyperemia.
