摘要
目的观察长寿老年(≥90岁)患者术前、术后心率变异性(HRV)的变化。方法选择择期非心脏手术老年患者12例,以动态心电图(DMSHolter5.0型)监测每例患者术前日23:00至术晨7:00及术后1、2d相同时间段HRV的变化。结果与术前比较,术后1、2d,总功率(TP)、高频功率(HF)、低频功率(LF)、LF/HF和极低频功率(VLF)明显降低(P<0.05或0.01)。结论经受麻醉、手术创伤等应激后,老年患者心自主神经功能受损,以交感神经调节心脏活性受损和均衡性改变为主。
Objective To observe the changes of the pre- and post-operative heart rate variability（HRV） in longevous senile patients （≥90 years old）. Methods Twelve senile patients undergone selective non-cardiac surgery were selected and changes of HRV were continuously monitored by dynamic electrocardiogram（DMS Holter 5.0, USA） from 23：00 intraday to 7：00 in the morning before operation. Results Compared with those before surgery, TP, HF, LF,LF/HF and VLF were significantly decreased on the 1^st days after surgery （P〈0. 05 or 0. 01）. Conclusion After the stresses such as anesthesia, surgical trauma, the functions of cardiac autonomic nervous system were impaired markedly in elder patients, manifested by impaired sympathetic modulation and the balance between sympathetic and parasympathetic nervous function.
