目的探讨脑外伤性蛛网膜下腔出血后血管痉挛引起的血流动力学改变的发生、发展规律及对预后的影响,为临床预防和治疗脑外伤性蛛网膜下腔出血后血管痉挛选择方法及治疗时间窗提供一种新的可靠的检测指标;方法采用经颅多普勒技术对98例脑外伤后蛛网膜下腔出血患者的血流动力学状态进行了动态观察,同时对经颅多普勒在脑外伤后蛛网膜下腔出血患者诊疗中的意义进行了探讨;结果血管痉挛与外伤性蛛网膜下腔出血的程度有关(P<0.05);血管痉挛累及的血管种类、数量血管痉挛持续的时间与预后密切相关(γ=0.642,P<0.05),本研究同时比较了经颅多普勒频谱及血流速度改变对血管痉挛检测的意义,发现频谱改变早于流速改变;结论脑外伤性蛛网膜下腔出血后血管痉挛引起的血流动力学改变是影响外伤性蛛网膜下腔出血患者预后的重要因素。
Objective To investigate the occurrence, development and prognosis of hemodynamic changes induced by vasospasm after traumatic subarachnoid hemorrhage and to provide a basis for the prevention and treatment of vasospasm after traumatic subarachnoid hemorrhage Treatment time window provides a new and reliable detection index; Methods The transcranial Doppler technique was used to analyze the hemodynamic status of 98 patients with subarachnoid hemorrhage after traumatic brain injury. At the same time, Le stroke in the diagnosis and treatment of patients with subarachnoid hemorrhage after traumatic brain injury were discussed; Results Vasospasm and traumatic subarachnoid hemorrhage degree (P <0.05); vasospasm involved in the types of blood vessels, the number of vasospasm continued (Γ = 0.642, P <0.05) .This study also compared the significance of transcranial Doppler spectrum and changes of blood flow velocity on the detection of vasospasm and found that the changes of the spectrum were earlier than the changes of the flow rate. Conclusion The brain injury Hemodynamic changes caused by vasospasm after sexual subarachnoid hemorrhage is an important factor affecting the prognosis of patients with traumatic subarachnoid hemorrhage.
