【摘要】 目的探讨颈髓损伤者24 h动态血压的变化规律。方法监测42例颈段(C3～C7)、45例胸腰段(T8～L4)脊髓损伤患者24h动态血压,分别比较两组白天坐位、立位收缩压(dSBP)和舒张压(dDBP),夜间卧位收缩压(nSBP)和舒张压(nDBP)以及收缩压的夜间血压下降率。结果两组白天立位收缩压和舒张压、夜间收缩压下降率有显著性差异(P<0.01),颈段脊髓损伤患者坐位、立位收缩压有显著性差异(P<0.01)。结论颈段脊髓损伤者存在体位性低血压,且夜间收缩压下降率倒置。更多还原

【Abstract】 Objective To explore 24-hour ambulatory blood pressure of patients with cervical spinal cord injury.Methods 42 patients with cervical spinal cord injury and 45 patients with thoracic-lumbar spinal cord injury were included.Their 24-hour ambulatory blood pressures were monitored.Their day systolic blood pressure(dSBP) and day diastolic blood pressure(dDBP) when seating and standing,night SBP and DBP,and SBP descending rate at night were compared.Results There were significant differences in dSBP and dDBP when standing,and SBP descending rate at night between 2 groups(P<0.01).There was significant difference in dSBP between seating and standing position in patients with cervical spinal cord injury(P<0.01).Conclusion There is orthostatic hypotension in cervical spinal cord injury patients and their SBP descending rate at night is upside down.更多还原
