短时心率变异测量辅助诊断儿童心血管神经机能症

应用短时心率变异(HRV)分析,研究44例心血管神经机能症患儿站、卧二个体位的自主神经功能。结果显示:与正常儿童相比,无论站或卧位患儿的SDNN、HRV INDEX、RMSSD、PNN50、TP、LF、HF、HFnorm均低于正常儿,统计处理有显著差异(P<0.01)。而HR、LF/HF、LFnorm较正常儿高,统计处理有差异(P<0.05)。结论:44例心血管神经机能症患儿,迷走神经活性降低,交感神经相对值增高,交感副交感平衡状态发生了改变。

心血管神经机能症的短时心率变异研究

应用短时心率变异（HRV）分析研究108例心血管神经机能症患者站卧两个体位的自主神经功能。结果显示：与正常人相比，心血管神经机能症患者站卧位的SDNN、HRVindex、RMSSD、PNN50、TP、LF、HF、HFnorm均低于正常人（P＜0．01）；而LF／HF、LFnorm高于正常人（P＜0．05）；正常人由卧位转为站位时，自主神经发生相应调节，表现交感神经活性增加，迷走神经活性降低。心血管神经机能症患者卧位变站位时HRV变化趋势与正常人基本相同，只是变化程度减小（LF／HF除外）。正常人SDNN、HRVindex、RMSSD、PNNS50、TP、LF、HFnorm与年龄呈负相关（P＜0．05）。心血管神经机能症患者除站位LF外，HRV各指标与年龄的相关比较均P＞0．05。

Near-infrared spectroscopy in adult cardiac surgery： between conflicting results and unexpected uses

Neurological complications after cardiac surgery, rang- ing from permanent stroke to transient dysfunction, repre- sent a key issue in the management of geriatric patients. Many patients aged 70 or more have history of neurological dysfunctions, which increases the risk of complications and sequelae, Severe neurologic diseases, such as strokes, occur in up to 6% of patients undergoing cardiac surgery. Therefore, in the setting of fragile patients, prevention is more important than treatment. There are several intraop- erative mechanisms of neurological injury, such as embo- lism, inflammation, intraoperative anemia,
