目的探讨脑外伤后TCD的表现和变化规律以及TCD与伤情及预后的关系。方法选择100例于伤后24~48h内入院的成年脑外伤患者行TCD检测。结果伤后1~3d出现血管痉挛,6~8d达峰值,10~13d已明显减轻;重伤组血管痉挛的发生率和程度明显高于轻伤组,血管痉挛程度越重,预后越差。结论TCD可及时、准确、无创的进行脑血管检测,有利于早期发现血管痉挛的发生及严重程度,可以作为指导治疗的一个指标。
Objective To investigate the changes of TCD after traumatic brain injury and the relationship between TCD and injury and prognosis. Methods 100 adult patients with traumatic brain injury admitted within 24-48 hours after injury were examined by TCD. Results Vasospasm occurred 1 ~ 3 days after injury and peaked at 6 ~ 8 days. It was significantly reduced at 10 ~ 13 days. The incidence and extent of vasospasm in severe injury group were significantly higher than those in slight injury group. The more vasospasm was, the worse the prognosis was. Conclusion TCD can be timely, accurate and noninvasive detection of cerebrovascular disease, is conducive to the early detection of the occurrence and severity of vasospasm, can be used as an indicator of treatment.
