We assessed the effects of Saam (traditional Korean) acupuncture on the autonomic nervous system in night-shift nurses using power-spectral heart-rate variability (HRV) analysis.
This study had a 2 × 4 cross-over design with a series of six (n = 1) controlled trials. Six night-shift nurses were randomly divided into two groups, and each nurse received four acupuncture treatments on the third day of night-shift work. One group started with Saam acupuncture (gallbladder jeonggyeok), while the other started with sham acupuncture. Saam acupuncture and sham acupuncture were applied in turn. HRV was measured before and after treatment. For statistical analysis, the results of the two groups were combined, and a Bayesian model was used to compare the changes in HRV values before and after treatment, between Saam and sham acupuncture.
As the ratio of low- to high-frequency power (LF/HF) for HRV increased on the third day of night-shift work in the pilot study, HRV measurements were made on the third day. Compared with sham acupuncture, Saam acupuncture reduced sympathetic activity; the overall median treatment effect estimate in LF normalised units decreased by -17.4 (confidence interval (CI): -26.67, -8.725) and that for LF/HF decreased by -1.691 (CI: -3.222, -0.3789). The overall median treatment effect estimate in HF normalised units increased by 17.41 (CI: 6.393, 27.13) with Saam acupuncture, suggesting an increase in parasympathetic activity.
Saam acupuncture may attenuate the imbalance between sympathetic and parasympathetic activities induced by night-shift work in nurses.
我们使用心率变异性（HRV）功率谱分析评估了传统韩式针刺（Saam）对倒班护士自主神经系统的影响。
本研究采用 2×4 交叉设计，共有 6 个（n=1）对照试验系列。6 名倒班护士随机分为两组，每位护士在夜班工作的第三天接受 4 次针刺治疗。一组先进行 Saam 针刺（胆囊经），另一组先进行 sham 针刺。Saam 针刺和 sham 针刺依次进行。治疗前后测量 HRV。统计分析时，将两组结果合并，采用贝叶斯模型比较治疗前后 HRV 值的变化，以及 Saam 针刺与 sham 针刺之间的差异。
在先导研究中，随着夜班第三天 HRV 中低到高频功率比（LF/HF）的增加，进行了 HRV 测量。与 sham 针刺相比，Saam 针刺降低了交感神经活性；LF 归一化单位的总体中位数治疗效果估计值降低了-17.4（置信区间：-26.67，-8.725），LF/HF 的降低了-1.691（置信区间：-3.222，-0.3789）。Saam 针刺使 HF 归一化单位的总体中位数治疗效果估计值增加了 17.41（置信区间：6.393，27.13），提示副交感神经活性增加。
Saam 针刺可能会减轻护士夜间工作引起的交感和副交感活动失衡。
