Objectives To investigate the clinical value of non-invasive ultrasound imaging in the evaluation of brain death caused by traumatic brain injury. Methods Thirty-four patients with acute severe traumatic brain injury were admitted to hospital within 48 h after injury. All patients were monitored intracranial pressure, transcranial Doppler, echocardiography examination, collection intracranial pressure, MCA-Vs, MCA-Vd, MCA-Vm, EF, LVMPI, RVMPI and other indicators, and combined with clinical conditions and other related data for comparative study and statistical analysis. Results The blood flow spectrum was characterized by diastolic retrograde blood flow spectrum pattern and nail waveform spectrum shape when the patient had clinical brain death. For the parameters of transcranial Doppler, there were significant differences in MCA-Vm and PI between clinical brain death group and normal control group (P < 0.05). For the parameters of echocardiography, there were statistically significant differences in EF, LVMPI, and RVMPI between clinical brain death group and normal control group (P < 0.05). Conclusion Non-invasive dynamic monitoring of cerebral hemodynamics and cardiac function parameters in patients with severe craniocerebral injury can provide a high accuracy and reliability for the preliminary diagnosis of brain death in patients with severe craniocerebral injury. It is helpful for early evaluation of prognosis and provides effective monitoring methods and guidance for clinical treatment.

超声成像对脑外伤所致脑死亡的无创评估

目的探讨无创超声成像在评估颅脑外伤所致脑死亡的临床价值。方法 34例急性重型颅脑损伤患者在伤后48 h内入院。监测所有患者颅内压、经颅多普勒、超声心动图检查、采集颅内压、MCA-Vs、MCA-Vd、MCA-Vm、EF、LVMPI、RVMPI等指标,并结合临床情况等相关数据进行对比研究和统计分析。结果临床脑死亡患者的血流谱表现为舒张期逆行血流谱型和指甲波形谱型。对于经颅多普勒参数,临床脑死亡组与正常对照组的MCA-Vm和PI比较差异有统计学意义(P < 0.05)。超声心动图参数方面,临床脑死亡组与正常对照组的EF、LVMPI、RVMPI差异有统计学意义(P < 0.05)。结论 对重型颅脑损伤患者的脑血流动力学和心功能参数进行无创动态监测,可为重型颅脑损伤患者脑死亡的初步诊断提供较高的准确性和可靠性。有助于早期评估预后,为临床治疗提供有效的监测方法和指导。临床脑死亡组与正常对照组的EF、LVMPI、RVMPI比较差异有统计学意义(P < 0.05)。结论 对重型颅脑损伤患者的脑血流动力学和心功能参数进行无创动态监测,可为重型颅脑损伤患者脑死亡的初步诊断提供较高的准确性和可靠性。有助于早期评估预后,为临床治疗提供有效的监测方法和指导。临床脑死亡组与正常对照组的EF、LVMPI、RVMPI比较差异有统计学意义(P < 0.05)。结论 对重型颅脑损伤患者的脑血流动力学和心功能参数进行无创动态监测,可为重型颅脑损伤患者脑死亡的初步诊断提供较高的准确性和可靠性。有助于早期评估预后,为临床治疗提供有效的监测方法和指导。结论 对重型颅脑损伤患者的脑血流动力学和心功能参数进行无创动态监测,可为重型颅脑损伤患者脑死亡的初步诊断提供较高的准确性和可靠性。有助于早期评估预后,为临床治疗提供有效的监测方法和指导。结论 对重型颅脑损伤患者的脑血流动力学和心功能参数进行无创动态监测,可为重型颅脑损伤患者脑死亡的初步诊断提供较高的准确性和可靠性。有助于早期评估预后,为临床治疗提供有效的监测方法和指导。
