摘　　要：目的　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病人2 4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 . 0 5 )。2例因脑充血死亡。结论　脑充血多为双侧性,可引起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 explore the cerebral hemodynamics and the effect of brain hyperemia in acute head-injured patients with intracranial hematomas (ICH) evacuated. Methods The velocities of basal 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 cranial decompressive windows. Results Two patients 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 the hyperemic group was higher than that of the nonhyperemic group. Conclusions 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.
