摘　　要：目的探讨星状神经节阻滞(SGB)对老年冠心病患者全麻诱导插管期心率变异性(HRV)的影响。方法60例择期行腹腔镜手术老年冠心病患者,随机分为对照组(C组)、左侧星状神经节阻滞组(L组)和右侧星状神经节阻滞组(R组),每组20例。L和R组行SGB后全身麻醉,C组只行全身麻醉。分别于入室后10min(T0)、麻醉诱导后(T1)及气管插管后(T2)用心率变异功率谱分析技术(HRPSA)观察患者HRV的变化。结果T1时三组HRV低频段(LF)、高频段(HF)、低频/高频(LF/HF)和总功率频段(TP)均显著降低(P<0.05),R组LF低于其他组(P<0.05);T2时三组LF、HF、LF/HF及TP较T0时均显著升高(P<0.05),R组LF与LF/HF升高程度显著低于其他组(P<0.05)。结论右侧SGB能抑制全麻诱导插管期的心脏交感神经活性,保持血液动力学稳定,提高老年冠心病患者全麻诱导插管期的安全性。Objective To investigate the effects of stellate ganglion block （SGB） on heart rate variability during induction and tracheal intubation of general anesthesia in the elderly with coronary heart disease （CHD）. Methods Sixty CHD patients were randomly divided into three groups （n= 20 each） Which were group C contrast, group L left SGB and group R right SGB. With power spectral analysis of heart rate variability, heart rate variability （HRV） was observed After entering operation room 10 min （To）, after induction （T1） and after intubation （T2）. Results Compared to at To ;LF, LF/HF, TP decreased significantly at T1, LF of group R was lower than that of the other groups. Compared to at T0,LF, LF/HF, TP increased significantly at T2, The LF and LF/HF levels in group R significantly lower than those of the other groups, Conelusion Right SGB significantly decrease the sympathetic nervous activity and maintain hemodynamic stability during induction and tracheal intubation of general anesthesia,impress the safety of induction and tracheal intubation in elderly with CHI.
