目的探讨激光散斑成像技术能否用于监测脊髓血流动力学的变化。
Objective to investigate whether laser speckle imaging technique can be used to monitor the changes of spinal cord hemodynamics.
结论脊髓损伤后持续性压迫使损伤脊髓血流量恢复减慢，病理损害加重。
Conclusion Continued compression aggravates pathologic injury through affecting the recovery of local spinal cord blood flow.
目的检测高位脊髓损伤患者伤后不同时期大脑动脉血流速度变化特点。
ObjectiveTo study the speciality of cerebral blood flow velocity of patients with spinal cord injury at different stages after injury.
同时用氢清除法检测脊髓灰质血流量的改变。
Meanwhile, the blood flow in the gray matter of spinal cord was determined by measuring the hydrogen clearance.
结论当转流量达到腹主动脉近端原血流量的70%时主动脉转流能较好地防止腹主动脉阻断1小时所造成的脊髓损伤。
Conclusion the spinal cord injury caused by abdominal aorta occlusion for 1 hour could be well prevented when the flow of aortic bypass was up to 70% of the volume of abdominal aorta flow.
急性脊髓损伤后血流动力学的变化提示进行性的“创伤后缺血”，静脉回流受阻可能是引起创伤后缺血的一个重要因素。
Such changes after acute spinal cord injury indicate progressive post-injury ischemia. The occlusion of veins may be an important contributor to post-injury ischemia.
