老年带状疱疹后神经痛患者的自主神经功能观察

INVESTIGATION OF AUTONOMIC NERVOUS FUNCTION IN GERIATRIC PATIENTS WITH POSTHERPETIC NEURALGIA

目的:观察老年带状疱疹后神经痛患者的自主神经状态。方法:选取老年带状疱疹后神经痛患者33例为观察组(P组),正常老年人50例为对照组(C组)。采用HRV检测仪,观察两组的心率变异性情况。结果:P组心率变异性频谱分析低频正常化单位(LF%)、低高频功率比值(LF/HF)明显高于C组(P>0.05);高频功率(HF)、低频功率(LF)和高频正常化单位(HF%)与C组相比无统计学差异性(P>0.05)。结论:老年带状疱疹后神经痛患者自主神经功能紊乱,交感神经功能处于优势。

Objective：To study the autonomic nervous function in geriatric patients with postherpetic neuralgia.Methods：A total of 83 geriatric subjects were divided into two groups.33 cases with postherpetic neuralgia were enrolled in the observation group （P group）,whereas 50 normal elderly people were included in the control group （C group）.The heart rate variability of subjects in the two groups was monitored by HRV detector.Results：The low frequency power in normalized unit （LF％） and ratio of LF to HF （LF/HF） in P group were both significantly higher than those in C group （P ＞ 0.05）.There was no significant difference between two groups in high frequency power （HF）,low frequency power （LF） and high frequency power in normalized unit （HF％） （P ＞ 0.05）.Conclusion：Compared with those in C group,geriatric patients with postherpetic neuralgia share the characteristics of autonomic nervous dysfunction and sympathetic hyperfunction.
