Abstract:
Objective To investigate the clinical value of measurement of phrenic nerve conduction function.Methods Evoked potentials of the phrenic nerve were measured in 292 patients with brachial plexus injuries.According to the normal value that was established in the electromyogram in our hospital,we divided them into normal and abnormal evoked potential groups,and then,the latent period and wave amplitude in the two groups were compared.Results Compared to those in the normal potential group,the latent period in abnormal group was significantly high and wave amplitude low(P＜0.05).Conclusion Measurement of phrenic nerve conduction is convenient,safe,and reliable to evaluate the conduction function of the phrenic nerve.
