目的研究右侧星状神经节阻滞对糖尿病患者自主神经功能的影响。方法 50例糖尿病患者接受了右侧星状神经节阻滞。记录并分析右侧星状神经节阻滞前后的平均动脉压(MAP)、心率(HR)及心率变异性(HRV),包括低频功率(LF),高频功率(HF)及LF/HF比值变化。结果与阻滞前比较,阻滞后HR下降[(84.6±6.5)次/分vs.(72.3±4.4)次/分](P<0.05),血压无明显变化。阻滞前后LF[(110.2±17.5)vs.(76.1±18.4)]和LF/HF比值[(2.42±1.41)vs.(1.52±1.32)],阻滞后显著小于阻滞前(P<0.01),HF无明显改变(P>0.05)。结论 右侧星状神经节阻滞通过调节交感-迷走神经活性,可使糖尿病患者自主神经系统功能的失衡状况得到改善。
Objective To study the effect of right stellate ganglion block on autonomic nervous function in diabetic patients. Methods Fifty patients with diabetes underwent right stellate ganglion block. Mean arterial pressure (MAP), heart rate (HR) and heart rate variability (HRV), including low frequency power (LF), high frequency power (HF) and LF / HF ratio before and after right stellate ganglion block were recorded and analyzed Variety. Results Compared with pre-arrest, the HR of post-arrest decreased [(84.6 ± 6.5) times / minute vs. (72.3 ± 4.4) beats / minute) (P <0.05). LF [(110.2 ± 17.5) vs. (76.1 ± 18.4)] and LF / HF ratio [(2.42 ± 1.41 vs. 1.52 ± 1.32)] before and after block were significantly lower than those before block (P <0.01 ), HF did not change significantly (P> 0.05). Conclusions Right stellate ganglion blockade improves the imbalance of autonomic nervous system function in diabetic patients by regulating sympathetic-vagal activity.
