男性頸脊髓損傷病患之膈神經傳導檢查

Abstract

phrenic nerve paralysis. For analysis influence of different level of C-SCI on phrenic nerve conduction study, we collected 51 cases including 35 cervical spinal cord injury (C-SCI) patients and 16 normal controls in this study. The patients were divided into the group A with C-SCI level above or at C4 (N=18), group B with C-SCI level below or at C5 (N=17)and group C with normal control subjects (N=16).The phrenic nerve was stimulated at the supramaximal level and the onset latency, amplitude and duration of compound muscle action potential (CMAP) were analyzed. The results are as followed : (1) The CMAP amplitude of group A is significantly less than group B and group C (P＜0.05,respectively). (2) The mean maximal CMAP amplitude is on the 7th intercostal space/anterior axillary line (ICS/AXL) of all the three groups except left side of group B. (3) When comparing the subgroup divided according to the severity of injury, we find that CMAP amplitude is lower on the more severe injury subgroup. (4)There are no difference of CMAP latency and duration in all three groups. The conclusions are as follow: (1) The CMAP amplitude of group A (high C- SCI combined with phrenic nerve injury) is significantly less than the other groups. (2) The best recording position is on the 7th intercostal space.
