急性外伤性颅内血肿病人CT及短潜时体感诱发电位动态观察

The consecutive observation of CT and SSEP for the patients with acute traumatic intracranial hematoma

目的探讨对急性外伤性颅内血肿 (ATICH)病人同时进行CT及短潜时体感诱发电位(SSEP)动态检查的临床意义及两者之间的关系。方法对 1 1 6例ATICH病人同时进行CT和SSEP动态检查 ,分析血肿类型、部位、血肿量与SSEP的关系 ,动态观察CT和SSEP的变化情况及两者间的关系。结果SSEP的变化与血肿类型、部位、血肿量密切相关 ,动态CT扫描可及时发现迟发性血肿、血肿或脑水肿的变化 ,并可及时发现新血肿的形成、术后血肿残留和再出血 ,SSEP可反映颅内结构的功能改变 ,并与CT变化基本一致。结论对ATICH病人同时进行CT和SSEP动态检查能全面客观地监测血肿的演变 。

Objective To study the relationship between computerized tomography (CT) and short latency somatosensory evoked potential (SSEP) and their value of dynamic observation for the patients with acute traumatic intracranial hematoma (ATICH). Methods The CT and SSEP of 116 patients with ATICH were consecutively observed. The category , location, volume of hematoma shown on CT were analysed. Results The changes of SSEP were significantly associated with category, location and volume of hematoma. The consecutive CT scan could reveal delayed hematoma, changes of primary hamatonma and edema, residual hematoma and bleeding after operation. The SSEP could find changes of cerebral function and the abnormal SSEP was mainly parallel with CT scan. Conclusion The consecutive observation of CT and SSEP could monitor the development of ATICH and aid in management for these patients.
