H反射在格林巴利综合征早期中的诊断价值

The Diagnostic Value of H Reflex in Early Stage of Guillain- Barre Syndrome

目的探讨H反射在格林巴利综合征(GBS)早期中的诊断价值。方法回顾性分析我院2014年1月至2016年1月30例GBS患者早期的神经电生理资料,结合神经传导速度(NCV)和F波,评估H反射在早期GBS的意义,其中H反射检测内容包括潜伏期、波幅;F波检测内容包括潜伏期、波幅、出现率;NCV检测内容包括:运动神经传导速度、波幅、远端潜伏期和感神经传导速度、波幅。结果30例GBS患者中,H反射异常率66.67%,F波异常率40%,NCV异常率23.33%。H反射异常率高于F波、NCV,差异具有统计学意义。结论 H反射是GBS早期的敏感指标,在进行格林巴利综合征患者的神经电生理检查时,H反射可作为常规检测项目。

Objective To explore the diagnostic value of H reflex in the early stage of Guillain-Barre syndrome（GBS）. Method The neuroelectrophysiologic al data of 30 patients with GBS from January 2014 to January 2016 were analyzed retrospectively. The significance of H reflexes in early GBS was evaluated by combining the nerve conduction velocity（NCV） and F wave. The content of H reflex detection Include latency, amplitude; F wave detection, including latency, amplitude, the incidence; NCV detection include： motor nerve conduction velocity, amplitude, distal latency and sensory nerve conduction velocity, amplitude. Result The abnormal rate of H reflex was 66.67%, the abnormal rate of F wave was 40% and the abnormal rate of NCV was 23.33% in 30 cases of GBS. H reflex abnormalities higher than F wave, NCV, the difference was statistically significant. Conclusion H reflex is a sensitive indicator of early GBS, in patients with Guillain-Barré syndrome neurophysiological examination, H reflex can be used as routine testing items.
